Subject: [PATCH 0002/3298] perf trace: Explicitly enable system-wide mode if
 no option is given

When no target cpu/user/task option is given, perf trace will do its job
system wide for all online cpus.  Make it explicit to reduce possible
confusion when reading code.

No functional changes intended.

Now perf trace is able to trace specified workload by forking it like
perf record does.  And also finish the tracing if the workload quits or

Adding -c option to select computation method with the current 'Delta'
computation as default. Current possible values are of this option are:
'delta' and 'ratio'.

Adding 'ratio' as new computation way to compare hist entries.  If
specified the 'Ratio' column is displayed with value 'r' computed as:

  r = A->period / B->period

with:
  - A/B being matching hist entry from first/second file specified
    (or perf.data/perf.data.old) respectively.
  - period being the hist entry period value

Adding support to sort hist entries based on the outcome of selected

'-c' option value to make such sort.

Example:

  $ perf diff -c ratio -b

  #
  #   Baseline           Ratio      Shared Object                            Symbol

         0.30%            0.17  [kernel.kallsyms]  [k] mm_alloc
         0.04%            0.20  [kernel.kallsyms]  [k] kmem_cache_alloc

  $ perf diff -c +ratio -b
  # Event 'cache-misses'
  #
  #   Baseline           Ratio      Shared Object                            Symbol

Subject: [PATCH 0007/3298] perf diff: Add weighted diff computation way to
 compare hist entries

Adding 'wdiff' as new computation way to compare hist entries.

If specified the 'Weighted diff' column is displayed with value 'd'
computed as:

   d = B->period * WEIGHT-A - A->period * WEIGHT-B

  - A/B being matching hist entry from first/second file specified
    (or perf.data/perf.data.old) respectively.
  - period being the hist entry period value
  - WEIGHT-A/WEIGHT-B being user suplied weights in the the '-c' option
    behind ':' separator like '-c wdiff:1,2'.

Subject: [PATCH 0013/3298] perf machine: Introduce find_thread method

There are cases where we want just to find a thread if it exists
already, so provide a method for that.

While doing that start moving 'machine' methods to a separate file.

Subject: [PATCH 0014/3298] perf event: No need to create a thread when
 handling PERF_RECORD_EXIT

When we were processing a PERF_RECORD_EXIT event we first used
machine__findnew_thread for both the thread exiting and for its parent,
only to use just the thread struct associated with the one exiting, and
to just delete it.

If it existed, i.e. not created at this very moment in
machine__findnew_thread, it will be moved to the machine->dead_threads
linked list, because we may have hist_entries pointing to it, but if it
was created just do be deleted, it will just sit there with no
references at all.

Use the new machine__find_thread() method so that if it is not there, we
don't create it.

As a bonus the parent thread will also not be created at this point.

Create process_fork() and process_exit() helpers to use this and make
the builtins use it instead of the generic process_task(), ditched by
this patch.

Noticed sched wasn't handling those events while introducing
perf_event__process_{fork,exit}.

Subject: [PATCH 0017/3298] perf machine: Carve up event processing specific
 from perf_tool

The perf_tool vtable expects methods that receive perf_tool and
perf_sample entries, but for tools not interested in doing any special
processing on non PERF_RECORD_SAMPLE events, like 'perf top', and for
those not using perf_session, like 'perf trace', they were using
perf_event__process passing tool and sample paramenters that were just
not used.

Provide 'machine' methods for this purpose and make the perf_event
ones use them.

Subject: [PATCH 0019/3298] perf kvm: Only process events for vcpus of interest

Minimizing processing overhead for each sample - which becomes important
for the upcoming live mode when it has to deal with 100+k events per
second.

Subject: [PATCH 0023/3298] perf tools: Add on_exit implementation

on_exit() is only available in new versions of glibc.
It is not implemented in Bionic and will lead to linking errors when
compiling for Android.

Implement a wrapper for on_exit using atexit.

The implementation for on_exit is the one sent by Bernhard Rosenkraenzer in
https://lkml.org/lkml/2012/8/23/316. The configuration part from the Makefile
is different than the one from the original patch.

Subject: [PATCH 0024/3298] perf tools: Update Makefile for Android

For cross-compiling on Android, some specific changes are needed in
the Makefile.

Update the Makefile to support cross-compiling for Android.
The original ideea for this was send by Bernhard Rosenkraenzer in
https://lkml.org/lkml/2012/8/23/316, but this is a rewrite.

Changes:
() support bionic in addition to glibc
() remove rt and pthread libraries that do not exist in Android
() use $(CFLAGS) when detecting initial compiler flags. This is needed
when setting CFLAGS as an argument of make (e.g. for setting --sysroot).
() include perf's local directory when building for Android to be able to find
relative paths if using --sysroot (e.g.: ../../include/linux/perf_event.h)

+How to compile perf for Android
+=========================================
+
+I. Set the Android NDK environment
+------------------------------------------------
+
+(a). Use the Android NDK
+------------------------------------------------
+1. You need to download and install the Android Native Development Kit (NDK).
+Set the NDK variable to point to the path where you installed the NDK:
+  export NDK=/path/to/android-ndk
+
+2. Set cross-compiling environment variables for NDK toolchain and sysroot.
+For arm:
+  export NDK_TOOLCHAIN=${NDK}/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-
+  export NDK_SYSROOT=${NDK}/platforms/android-9/arch-arm
+For x86:
+  export NDK_TOOLCHAIN=${NDK}/toolchains/x86-4.6/prebuilt/linux-x86/bin/i686-linux-android-
+  export NDK_SYSROOT=${NDK}/platforms/android-9/arch-x86
+
+This method is not working for Android NDK versions up to Revision 8b.
+perf uses some bionic enhancements that are not included in these NDK versions.
+You can use method (b) described below instead.
+
+(b). Use the Android source tree
+-----------------------------------------------
+1. Download the master branch of the Android source tree.
+Set the environment for the target you want using:
+  source build/envsetup.sh
+  lunch
+
+2. Build your own NDK sysroot to contain latest bionic changes and set the
+NDK sysroot environment variable.
+  cd ${ANDROID_BUILD_TOP}/ndk
+For arm:
+  ./build/tools/build-ndk-sysroot.sh --abi=arm
+  export NDK_SYSROOT=${ANDROID_BUILD_TOP}/ndk/build/platforms/android-3/arch-arm
+For x86:
+  ./build/tools/build-ndk-sysroot.sh --abi=x86
+  export NDK_SYSROOT=${ANDROID_BUILD_TOP}/ndk/build/platforms/android-3/arch-x86
+
+3. Set the NDK toolchain environment variable.
+For arm:
+  export NDK_TOOLCHAIN=${ANDROID_TOOLCHAIN}/arm-linux-androideabi-
+For x86:
+  export NDK_TOOLCHAIN=${ANDROID_TOOLCHAIN}/i686-linux-android-
+
+II. Compile perf for Android
+------------------------------------------------
+You need to run make with the NDK toolchain and sysroot defined above:
+  make CROSS_COMPILE=${NDK_TOOLCHAIN} CFLAGS="--sysroot=${NDK_SYSROOT}"
+
+III. Install perf
+-----------------------------------------------
+You need to connect to your Android device/emulator using adb.
+Install perf using:
+  adb push perf /data/perf
+
+If you also want to use perf-archive you need busybox tools for Android.
+For installing perf-archive, you first need to replace #!/bin/bash with #!/system/bin/sh:
+  sed 's/#!\/bin\/bash/#!\/system\/bin\/sh/g' perf-archive >> /tmp/perf-archive
+  chmod +x /tmp/perf-archive
+  adb push /tmp/perf-archive /data/perf-archive
+
+IV. Environment settings for running perf
+------------------------------------------------
+Some perf features need environment variables to run properly.
+You need to set these before running perf on the target:
+  adb shell
+  # PERF_PAGER=cat
+
+IV. Run perf
+------------------------------------------------

Subject: [PATCH 0026/3298] mtd: nand: fix Samsung SLC NAND identification
 regression

A combination of the following two commits caused a regression in 3.7-rc1
when identifying some Samsung NAND, so that some previously working NAND
were no longer detected properly:

    commit e3b88bd604283ef83ae6e8f53622d5b1ffe9d43a
    mtd: nand: add generic READ ID length calculation functions

    commit e2d3a35ee427aaba99b6c68a56609ce276c51270
    mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID

Particularly, a regression was seen on Samsung K9F2G08U0B, with the
following full 8-byte READ ID string:

    ec da 10 95 44 00 ec da

The basic problem is that Samsung manufactures both SLC and MLC NAND
that use a non-standard decoding table for deriving information from
their IDs. I have heuristically determined that all the chips that use
the new table have ID strings which wrap around after the 6th byte.
Unfortunately, I overlooked the fact that some older Samsung SLC (which
use a different decoding table) have "5 byte ID strings" which also wrap
around after the 6th byte.

This patch re-introduces a distinction between these old and new Samsung
NAND by checking that the 6th byte is non-zero, allowing both old and
new Samsung NAND to be detected properly.

Subject: [PATCH 0027/3298] mtd: ofpart: Fix incorrect NULL check in
 parse_ofoldpart_partitions()

The pointer returned by kzalloc should be tested for NULL
to avoid potential NULL pointer dereference later. Incorrect
pointer was being tested for NULL. Bug introduced by commit fbcf62a3
(mtd: physmap_of: move parse_obsolete_partitions to become separate
parser).
This patch fixes this bug.

Subject: [PATCH 0028/3298] arm: at91: use macro to declare soc boot data

Instead of check the pointer of the init function, check the new builtin bool
to known if the soc is enabled.

This is needed as with the switch to the pinctrl the init will be NULL on pure
DT SoC.

Configure the pin as pio when requested.

It is needed to configure the pin as PIO at "request time" when we are
using DT. Indeed, the muxing via old AT91 API is not allowed anymore if
we are using the plain gpiolib.

Subject: [PATCH 0031/3298] arm: at91: at91sam9x5: fix gpio number per bank

On the at91sam9x5 SoC series, GPIO banks B and D only have 19 and 22
pins. So add a property to set this parameter.

Subject: [PATCH 0033/3298] ARM: at91: add pinctrl support

This is also include the gpio controller as the IP share both.
Each soc will have to describe the SoC limitation and pin configuration via
DT.

This will allow to do not need to touch the C code when adding new SoC if the
IP version is supported.

+* Atmel AT91 Pinmux Controller
+
+The AT91 Pinmux Controler, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called periph modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the contoller controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Atmel AT91 pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'pins' selects the function mode(also named pin
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, multi drive, etc.
+
+Required properties for iomux controller:
+- compatible: "atmel,at91rm9200-pinctrl"
+- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
+  configured in this periph mode. All the periph and bank need to be describe.
+
+How to create such array:
+
+Each column will represent the possible peripheral of the pinctrl
+Each line will represent a pio bank
+
+Take an example on the 9260
+Peripheral: 2 ( A and B)
+Bank: 3 (A, B and C)
+=>
+
+  /*    A         B     */
+  0xffffffff 0xffc00c3b  /* pioA */
+  0xffffffff 0x7fff3ccf  /* pioB */
+  0xffffffff 0x007fffff  /* pioC */
+
+For each peripheral/bank we will descibe in a u32 if a pin can can be
+configured in it by putting 1 to the pin bit (1 << pin)
+
+Let's take the pioA on peripheral B
+From the datasheet Table 10-2.

+
+Required properties for pin configuration node:
+- atmel,pins: 4 integers array, represents a group of pins mux and config
+  setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
+  The PERIPH 0 means gpio.
+
+Bits used for CONFIG:
+PULL_UP(1 << 0): indicate this pin need a pull up.
+MULTIDRIVE(1 << 1): indicate this pin need to be configured as multidrive.
+
+NOTE:
+Some requirements for using atmel,at91rm9200-pinctrl binding:
+1. We have pin function node defined under at91 controller node to represent
+   what pinmux functions this SoC supports.
+2. The driver can use the function node's name and pin configuration node's
+   name describe the pin function and group hierarchy.
+   For example, Linux at91 pinctrl driver takes the function node's name
+   as the function name and pin configuration node's name as group name to
+   create the map table.
+3. Each pin configuration node should have a phandle, devices can set pins
+   configurations by referring to the phandle of that pin configuration node.
+4. The gpio controller must be describe in the pinctrl simple-bus.
+
+Examples:
+
+pinctrl@fffff400 {
+	#address-cells = <1>;
+	#size-cells = <1>;
+	ranges;
+	compatible = "atmel,at91rm9200-pinctrl", "simple-bus";
+	reg = <0xfffff400 0x600>;
+
+	atmel,mux-mask = <
+	      /*    A         B     */
+	       0xffffffff 0xffc00c3b  /* pioA */
+	       0xffffffff 0x7fff3ccf  /* pioB */
+	       0xffffffff 0x007fffff  /* pioC */
+	      >;
+
+	/* shared pinctrl settings */
+	dbgu {
+		pinctrl_dbgu: dbgu-0 {
+			atmel,pins =
+				<1 14 0x1 0x0	/* PB14 periph A */
+				 1 15 0x1 0x1>;	/* PB15 periph with pullup */
+		};
+	};
+};
+
+dbgu: serial@fffff200 {
+	compatible = "atmel,at91sam9260-usart";
+	reg = <0xfffff200 0x200>;
+	interrupts = <1 4 7>;
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_dbgu>;
+	status = "disabled";

Subject: [PATCH 0035/3298] arm: at91: dt: at91sam9 add serial pinctrl support

Set the dbgu pinctrl config by default as we have only one possible config
For other uart set the rxd/txd by default.

For at91sam9x5ek create soc based dts as we need to include specific soc dtsi.

 devm_kzalloc()

The rest of the driver is using devm_kzalloc() where possible
and this patch is just making event buffer allocation follow
the example.

Subject: [PATCH 0043/3298] usb: dwc3: core: move event buffer allocation out
 of dwc3_core_init()

This patch is in preparation for adding PM support
dwc3 driver. We want to re-use dwc3_core_init and
dwc3_core_exit() functions on resume() and suspend()
callbacks respectively.

Moving even buffer allocation away from dwc3_core_init()
will allow us to reuse the event buffer which was allocated
long ago on our probe() routine.

Subject: [PATCH 0051/3298] tick: Consolidate tick handling for high and low
 res handlers

Besides unifying code, this also adds the idle check before
processing idle accounting specifics on the low res handler.
This way we also generalize this part of the nohz code for
!CONFIG_HIGH_RES_TIMERS to prepare for the adaptive tickless
features.

Subject: [PATCH 0056/3298] GPIO: Add support for GPIO on CLPS711X-target
 platform

The CLPS711X CPUs provide some GPIOs for use in the system. This
driver provides support for these via gpiolib. Due to platform
limitations, driver does not support interrupts, only inputs and
outputs.

Subject: [PATCH 0059/3298] usb: phy: tegra remove include of <mach/iomap.h>

Almost nothing from this file is used, and the file will hopefully be
deleted soon. Copy the tiny portions that are used directly into
tegra_usb_phy.c. I believe that Venu Byravarasu is working on cleaning up
our USB driver, and those cleanups will remove the need for these
constants.

Subject: [PATCH 0063/3298] usb: dwc3: drop HAVE_CLK dependency from Exynos
 glue layer

commit 93abe8e (clk: add non CONFIG_HAVE_CLK routines)
added clk API stubs when !defined(CONFIG_HAVE_CLK).

This allows us to remove the HAVE_CLK dependency from
Exynos' glue layer and let it compile always.

Subject: [PATCH 0071/3298] staging/iio/lis3l02dq: fix building without
 irq_to_gpio

The driver has not been building for some time after the
irq_to_gpio function has been removed from the kernel.

The only board in the upstream kernel that provides
this device is the "Stargate 2", which is also maintained
by Jonathan Cameron. Rather than working around the problem
by adding new platform data for this driver, this patch
uses the of_gpio framework to get to the gpio number.

However, the stargate2 code does not (yet) use DT based
probing, so it is still broken, but at least building
allyesconfig works again.

Subject: [PATCH 0078/3298] iio: Add a logarithmic fractional value type

For ADCs or DACs the denominator for fractional types often is a power of two.
In this case we can use a shift operation instead of the rather expensive 64 bit
division. This patch adds a new fractional type which expects the denominator to
be specified as the log2 of the actual denominator. E.g. for ADCs and DACs this
will usually be the number of significant bits.

Subject: [PATCH 0081/3298] Staging: ipack: Make ipack_device_register()
 analogous to device_register().

ipack_device_register() is no longer creating the struct ipack_device
but only registering it.  Instead of releasing memory directly the new
ipack_device->release callback is called.

This is preparational work for later patches.

From bb29ab86d18da68e5c7f05814c07d5eb8bdb4652 Mon Sep 17 00:00:00 2001
From: Jens Taprogge <jens.taprogge@taprogge.org>
Date: Thu, 27 Sep 2012 12:37:28 +0200
Subject: [PATCH 0083/3298] Staging: ipack/bridges/tpci200: change
 tpci200_slot->*_phys type.

Previously the *_phys fields were of type ipack_addr_space, which use
void pointers to refer to memory addresses.  Since the *_phys fields
refer to unmapped memory, this is not correct.  Introduce a new struct
ipack_region (which uses phys_addr_t to refer to the start of a region)
and use that as a replacement for struct ipack_addr_space.

struct ipack_region is defined in ipack.h because it is planned to later
expose the physical addressed to the IPack Module drivers.

Subject: [PATCH 0085/3298] Staging: ipack/bridges/tpci200: Cleanups.

Constant renames:
 - Rename TPCI200_*_GAP to TPCI200_*_INTERVAL.
 - Rename TPCI200_MEM*_* to TPCI200_MEM*_SPACE_* (to match the other SPACE
   constants.

Make tpci200_status_timeout and tpci200_status_error const.

Subject: [PATCH 0090/3298] Staging: ipack: remove memory mapping callbacks.

Now that we have the infrastructure to use the regular function in place
and all existing users are converted, remove the map and unmap callbacks
from the ipack_bus_device->ops.

Subject: [PATCH 0091/3298] staging: ipack: Rename IPACK_MEM_SPACE to
 IPACK_MEM8_SPACE.

There also is a MEM16 space.  This will make it clear which one is
which, once support for MEM16 space is added.

Subject: [PATCH 0107/3298] Staging: bcm: Remove unneeded do while loop in
 InterfaceRDM.

This patch removes an unneeded do while loop which
sends a control message to bcm usb device. In this case,
the loop executes once because usRetries is
initialized to zero. After the first iteration
this variable will be 1. Therefore, the statement:
"usRetries < MAX_RDM_WRM_RETIRES" will evaluate to
false causing the do while statement to execute
once because MAX_RDM_WRM_RETIRES is equal to 1.

Subject: [PATCH 0118/3298] Staging: bcm: Clean up function
 CopyBufferToControlPacket in Misc.c

This patch cleans up the code in function
CopyBufferToControlPacket. Several things are
being done here: (1) remove the null
initialization from variable cntrl_buff, (2)
reverse the if statement to check if cntrl_buff
is null; if so, then write debug statement and
return -ENOMEM error code, and (3) indent the
code properly.

"==" sign, and TRUE to the right of
the equal "==" sign. This was done for

Subject: [PATCH 0120/3298] rcu: Accelerate callbacks for CPU initiating a
 grace period

Because grace-period initialization is carried out by a separate
kthread, it might happen on a different CPU than the one that
had the callback needing a grace period -- which is where the
callback acceleration needs to happen.

Fortunately, rcu_start_gp() holds the root rcu_node structure's
->lock, which prevents a new grace period from starting.  This
allows this function to safely determine that a grace period has
not yet started, which in turn allows it to fully accelerate any
callbacks that it has pending.  This commit adds this acceleration.

Subject: [PATCH 0124/3298] EHCI: improved logic for isochronous scheduling

This patch (as1608) reworks the logic used by ehci-hcd for scheduling
isochronous transfers.  Now the modular calculations are all based on
a window that starts at the last frame scanned for isochronous
completions.  No transfer descriptors for any earlier frames can
possibly remain on the schedule, so there can be no confusion from
schedule wrap-around.  This removes the need for a "slop" region of
arbitrary size.

There's no need to check for URBs that are longer than the schedule
length.  With the old code they could throw things off by wrapping
around and appearing to end in the near future rather than the distant
future.  Now such confusion isn't possible, and the existing test for
submissions that extend too far into the future will also catch those
that exceed the schedule length.  (But there still has to be an
initial test to handle the case where the schedule already extends as
far into the future as possible.)

Delays caused by IRQ latency won't confuse the algorithm unless they
are ridiculously long (over 250 ms); they will merely reduce how far
into the future new transfers can be scheduled.  A few people have
reported problems caused by delays of 50 ms or so.  Now instead of
failing completely, isochronous transfers will experience a brief
glitch and then continue normally.

(Whether this is truly a good thing is debatable.  A latency as large
as 50 ms generally indicates a bug is present, and complete failure of
audio or video transfers draws people's attention pretty vividly.
Making the transfers more robust also makes it easier for such bugs to
remain undetected.)

Finally, ehci->next_frame is renamed to ehci->last_iso_frame, because
that better describes what it is: the last frame to have been scanned
for isochronous completions.

Subject: [PATCH 0125/3298] EHCI: use the isochronous scheduling threshold

This patch (as1609) changes the way ehci-hcd uses the "Isochronous
Scheduling Threshold" in its calculations.  Until now the code has
ignored the threshold except for certain Intel PCI-based controllers.
This violates the EHCI spec.

The new code takes the threshold into account always, removing the
need for the fs_i_thresh quirk flag.  In addition it implements the
"full frame cache" setting more efficiently, moving forward only as
far as the next frame boundary instead of always moving forward 8
microframes.

Subject: [PATCH 0128/3298] EHCI: implement new semantics for URB_ISO_ASAP

This patch (as1612) updates the isochronous scheduling and processing
in ehci-hcd to match the new semantics for URB_ISO_ASAP.  It also adds
a missing "unlikely" in sitd_complete() to match the corresponding
statement in itd_complete(), and it increments urb->error_count in a
couple of places that had been overlooked.

This patch (as1614) updates the isochronous scheduling in ohci-hcd to
match the new semantics for URB_ISO_ASAP.  Testing revealed a hardware
bug in the way my OHCI controller handles expired isochronous TDs;
consequently the patch tries hard to avoid creating them (unlike the
ehci-hcd and uhci-hcd drivers).

Subject: [PATCH 0132/3298] USB: OHCI: remove ohci-pcc-soc driver.

This driver is not registered by any in-tree users, and if really needed by
some out of tree user, the same functionnality can be restored using the
ohci-platform driver using the following platform_data parameters:
	big_endian_desc = 1
	big_endian_mmio = 1
	no_big_frame_no = 1

Subject: [PATCH 0137/3298] USB: EHCI: add no_io_watchdog platform_data
 parameter to ehci-platform

Enhance the ehci-platform driver to also accept no_io_watchdog as a platform
data parameter. When no_io_watchdog is set to 1, the ehci controller will set
ehci->need_io_watchdog to 0. Since most EHCI controllers do need the I/O
watchdog to be on, only let those which need it to turn the watchdog off.

Make sure that we change need_io_watchdog after the call to ehci_setup()
because ehci_setup() will unconditionnaly set need_io_watchdog to 1.

Subject: [PATCH 0140/3298] ARM: cns3xxx: use ehci platform driver

This patch converts the cns3xxx platform to use the ehci-platform driver
instead of the ehci-cns3xxx platform driver.

The ehci-platform driver is provided with power_{on,off} callbacks to ensure
proper block gating and USB configuration of the EHCI controller.

Subject: [PATCH 0141/3298] USB: EHCI: remove CNS3xxx EHCI platform driver

The users have been converted to use the ehci platform driver instead, thus
making the ehci-cns3xxx driver obsolete, so remove it.

Subject: [PATCH 0142/3298] USB: ohci: allow platform driver to specify the
 number of ports

This patch modifies the ohci platform driver to accept the num_ports
parameter to be set via platform_data. Setting the number of ports must be
done after the call to ohci_hcd_init().

As suggested by Alan Stern, move the ohci-pci.c ohci_pci_{suspend,resume}
routines to ohci-hcd.c. Due to their move, also rename them to
ohci_{suspend,resume} to make it clear they operate on ohci_hcd. Since they
are not necessarily called, annotate them with __maybe_unused, and make them
enclosed within an #ifdef CONFIG_PM / #endif section.

 ohci_resume

Merge ohci_finish_controller_resume with ohci_resume as suggested by Alan
Stern. Since ohci_finish_controller_resume no longer exists, update the
various OHCI drivers to call ohci_resume() instead. Some drivers used to set
themselves the bit HCD_FLAG_HW_ACCESSIBLE, which is now handled by
ohci_resume().

Subject: [PATCH 0148/3298] ARM: cns3xxx: use OHCI platform driver

This patch converts the cns3xxx platform to use the ohci-platform driver which
is now suitable for use.

A previous patch converted the cns3xxx platform to use the ehci-platform
driver, and thus introduced the need to have power_{on,off} callbacks.
Since both the EHCI and OHCI platform drivers use the same same power_{on,off}
callbacks now, rename them to cns3xx_usb_power_{on,off} to show that they are
shared.

Subject: [PATCH 0154/3298] MIPS: Alchemy: use the OHCI platform driver

Convert the Alchemy platform to register the ohci-platform driver, now that
the ohci-platform driver properly handles the specific ohci-au1xxx resume
from suspend case.

This also greatly simplifies the power_{on,off} callbacks and make them
work on platform device id instead of checking the OHCI controller base
address like what was done in ohci-au1xxx.c.

Impacted defconfigs are also updated accordingly to select the OHCI platform
driver.

Subject: [PATCH 0156/3298] USB: move common alchemy USB routines to
 arch/mips/alchemy/common.c

A previous patch converted the Alchemy platform to use the OHCI and EHCI
platform drivers. As a result, all the common logic to handle USB present in
drivers/usb/host/alchemy-common.c has no reason to remain here, so we move it
to arch/mips/alchemy/common/usb.c which is a more appropriate place. This
change was suggested by Manuel Lauss.

This patch changes the ehci-platform driver to use the device managed helper
function for requesting memory region and ioremapping memory resources.
As a result the error path in the probe function is simplified, and the
platform driver remove callback does no longer need to release and iounmap
memory resources. devm_request_and_ioremap() will use either the ioremap()
or ioremap_nocache() handler depending on the resource's CACHEABLE flag, so
we are good with this change.

Subject: [PATCH 0165/3298] staging/olpc_dcon: move wait queue into dcon_priv
 struct

Another global variable (dcon_wait_queue) moved into the dcon_priv struct.
In the process, replace an instance of a manually implemented
wait_event_timeout.  This code came from Jordan's original gxfb_dcon.c
driver waaaay back in 2006; well past time for a replacement.

Subject: [PATCH 0166/3298] staging/olpc_dcon: drop fb_notifier code

Previously we registered a notifier block to inform us of any framebuffer
device changes; if the screen was blanked or unblanked, we'd put the DCON
to sleep or wake it up.

Turns out that the backlight code registers a notifier block as well
and calls the update_status hook, so we can just use that to put the DCON
to sleep.  For those status updates where the blanking isn't changed,
dcon_sleep will do nothing.

Subject: [PATCH 0167/3298] staging/olpc_dcon: drop pin frobbing code for xo1.5

This code looks in the PCI config space for pin addresses and sets up some
stuff.  However, Openfirmware has already done this for us, so there's no
need to ever do it in Linux.  According to Mitch Bradley, this OFW has been
doing this for us since at least B3 builds (pre-mass production).

Subject: [PATCH 0172/3298] staging: comedi: ssv_dnp: remove boardinfo

This driver only supports a single "boardtype". Remove the unneeded
boardinfo struct and its use in the driver. Change the "driver_name"
to match what the boardinfo supplied.

Subject: [PATCH 0185/3298] staging: comedi: cb_pcidas64: remove inline priv()
 function

The inline priv() function simply returns the dev->private pointer
to the private data.

Remove the inline funciton and just use a local variable where the
private data is used.

From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Mon, 15 Oct 2012 10:13:50 -0700
Subject: [PATCH 0186/3298] staging: comedi: gsc_hpdi: remove inline priv()
 function

The inline priv() function simply returns the dev->private pointer
to the private data.

Remove the inline function and just use a local variable where the
private data is used.

Subject: [PATCH 0187/3298] staging: comedi: ni_65xx: remove inline private()
 function

The inline private() function simply returns the dev->private pointer
to the private data.

Remove the inline function and just use a local variable where the
private data is used.

Subject: [PATCH 0189/3298] staging: comedi: poc: introduce struct poc_private

Wrap the private data used by this driver in a struct. This makes
the use of that data clearer and gets rid of the need for the casts.

From 0e05c55226bffcdd3f1393d5ab74cd0d9faff385 Mon Sep 17 00:00:00 2001
From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Mon, 15 Oct 2012 10:19:06 -0700
Subject: [PATCH 0191/3298] staging: comedi: ni_mio_common: remove devpriv
 macro

The ni_mio_common.c file is #include'd by the ni_atmio, ni_mio_cs,
and ni_pcimio drivers. Those drivers all have a devpriv macro of
this type:

This macro relies on a local variable having a specific name.
Remove its use in all the files by replacing it with a local
variable.

Some of the functions in ni_mio_common.c don't always use the
devpriv variable due to differences in how the low-level i/o
is handled by the driver. Tag the variable in those functions
with __maybe_unused to avoid compile warnings.

Subject: [PATCH 0192/3298] staging: comedi: drivers: remove remaining devpriv
 macros

The remaining comedi drivers that still have a devpriv macro
are all pretty straight forward for removing the devpriv
macro.

This macro relies on a local variable having a specific name.
Remove its use by replacing it with a local variable where
used.

The inline function alloc_private(), used to kzalloc the
dev->private memory, returns non-zero if there is an error.
Fix all the alloc_private() calls accordingly and remove any
kernel messages or obvious comments that still exist in the
drivers. Leave a comment in the skel driver.

Date: Mon, 15 Oct 2012 10:16:38 -0700
Subject: [PATCH 0193/3298] staging: comedi: s626: remove devpriv macro

Missed one... This macro relies on a local variable having
a specific name. Remove its use by replacing it with a local
variable where used.

Subject: [PATCH 0194/3298] staging: comedi: avoid a put_device(), get_device()
 sequence

In `comedi_set_hw_dev()`, if there is no change to `dev->hw_dev` (and it
is not `NULL`), don't bother putting and getting the device.

Subject: [PATCH 0195/3298] staging: comedi: always set hw_dev during
 auto-config

Auto-configuration (auto-attachment) of USB and PCI comedi devices all
goes through `comedi_auto_config_helper()`.  That is a good place to set
the comedi device's `hw_dev` pointer to the hardware `struct device` via
a call to `comedi_set_hw_dev(comedi_device, hardware_device)` as it may
obviate the need for the low-level comedi driver to make this call.

Subject: [PATCH 0208/3298] staging: vt6656: [BUG] out of bound array reference
 in RFbSetPower.

Calling RFbSetPower with uCH zero value will cause out of bound array reference.

This causes 64 bit kernels to oops on boot.

Note: Driver does not function on 64 bit kernels and should be
blacklisted on them.

Subject: [PATCH 0220/3298] staging: usbip: replaced pointer arithmetic, and
 strongly type function return.

Replaced pointer arithmetic by using array indexing, and changed
function return type for usbip_alloc_iso_desc_pdu from 'void*' to
'struct usbip_iso_packet_descriptor'.

Subject: [PATCH 0223/3298] staging: usbip: Don't leak struct file.

usbip takes a reference on a struct file which is passed in via
sysfs.  Previously, this reference was never cleaned up, although
the socket it referred to was.

This patch drops the corresponding reference (found with the
socket's ->file backpointer) instead of just closing the socket.

-        Note: when specifying an origin (originName is not NULL and not zero
-        length), this function can only be used for origins that use the
-        csr_log_text_2.h interface for registration and logging. Filtering for
-        origins that use the legacy csr_log_text.h interface must be be
-        configured using the legacy filter configuration functions that accept
-        a CsrLogTextTaskId as origin specifier. However, when not specifying an
-        origin this function also affects origins that have been registered with
-        the legacy csr_log_text.h interface. Furthermore, using this function
-        and the legacy filter configuration functions on the same origin is not
-        allowed.

Subject: [PATCH 0248/3298] gpiolib: Refactor gpio_export

The gpio_export function uses nested if statements and the status
variable to handle the failure cases. This makes the function logic
difficult to follow. Refactor the code to abort immediately on failure
using goto. This makes the code slightly longer, but significantly
reduces the nesting and number of split lines and makes the code easier
to read.

Subject: [PATCH 0249/3298] staging: dgrp: fix some warnings

Just squashing these to get them out of the analysis queue.

nd_ps_desc is an array not a pointer so comparing it with NULL is silly (be
nice if gcc shouted about this). And there are some slightly pointless
comparisons too.

Subject: [PATCH 0253/3298] drm/omap: Fix release of refill engine

During asynchronous refills, we don't wait for the refill to
finish.  However, we cannot release the engine back to the idle
list until it has actually completed the refill operation.  The
engine release will now be done in the IRQ handler, but only
for asynchronous refill operations.

Synchronous refills will continue to release the engine after they
unblock from waiting on the refill.

Subject: [PATCH 0254/3298] drm/omap: fix issue w/ fb attached to multiple
 CRTCs

When the fb is detached from one CRTC/plane, paddr was set back to
zero.  But really we don't want to do this because the fb could still
be attached to other CRTC/plane(s).  This originally worked like this
to catch cases of freeing a pinned fb (but with the refcnt'ing this
should no longer be needed).  Also, there is checking in the GEM code
for freeing a pinned GEM object, so this extra level of checking is
redundant.

Subject: [PATCH 0260/3298] staging: ccg: rename ccg init and exit functions to
 conventional names

Previous names of init and exit functions "init" and "cleanup" are
unconventional and are not friendly for source navigation with tags.
New names "ccg_init" and "ccg_exit" are conveninal and source navigation
friendly.

The line6 driver does not support 'index' and 'id' module parameters so
there is no need to keep arrays for these values.  Do what other sound
drivers do and use the scalar constants instead of dummy arrays.

    a loadable module.
  - Rename some symbols with prefix 'rts51x_' to prevent symbol name collisions
    with drivers/staging/rts_pstor when both are configured to be built-in
    objects.

Subject: [PATCH 0270/3298] staging: et131x: Use skb_headlen() where
 appropriate

(skb->len - skb->data_len) is used in several places in the et131x
driver code. Converted all instances of this to use skb_headlen()
which is more readable.

Subject: [PATCH 0271/3298] staging: et131x: Fix 64bit tx dma address handling

The driver checks that the device can handle 64bit DMA addressing in
et131x_pci_setup(), but then assumes that the top dword of a tx dma
address is always zero when creating a dma mapping in nic_send_packet().
Fix the mapping to use the higher dword of the dma_addr_t returned by
dma_map_single() and skb_frag_dma_map().

Also remove incorrect comments stating that dma_map_single() only returns
a 32 bit address.

Subject: [PATCH 0274/3298] staging: et131x: Remove USE_FBR0 define and #ifdefs

USE_FBR0 has always been defined, even in the original driver code.
Remove the define and #ifdef code to leave the code in the same state.

Subject: [PATCH 0277/3298] PM / QoS: Prepare device structure for adding more
 constraint types

Currently struct dev_pm_info contains only one PM QoS constraints
pointer reserved for latency requirements.  Since one more device
constraints type (i.e. flags) will be necessary, introduce a new
structure, struct dev_pm_qos, that eventually will contain all of
the available device PM QoS constraints and replace the "constraints"
pointer in struct dev_pm_info with a pointer to the new structure
called "qos".

Subject: [PATCH 0278/3298] PM / QoS: Introduce request and constraint data
 types for PM QoS flags

Introduce struct pm_qos_flags_request and struct pm_qos_flags
representing PM QoS flags request type and PM QoS flags constraint
type, respectively.  With these definitions the data structures
will be arranged so that the list member of a struct pm_qos_flags
object will contain the head of a list of struct pm_qos_flags_request
objects representing all of the "flags" requests present for the
given device.  Then, the effective_flags member of a struct
pm_qos_flags object will contain the bitwise OR of the flags members
of all the struct pm_qos_flags_request objects in the list.

Additionally, introduce helper function pm_qos_update_flags()
allowing the caller to manage the list of struct pm_qos_flags_request
pointed to by the list member of struct pm_qos_flags.

The flags are of type s32 so that the request's "value" field
is always of the same type regardless of what kind of request it
is (latency requests already have value fields of type s32).

Subject: [PATCH 0279/3298] PM / QoS: Prepare struct dev_pm_qos_request for
 more request types

The subsequent patches will use struct dev_pm_qos_request for
representing both latency requests and flags requests.  To make that
easier, put the node member of struct dev_pm_qos_request (under the
name "pnode") into a union called "data" that will represent the
request's  value and list node depending on its type.

Subject: [PATCH 0280/3298] PM / QoS: Introduce PM QoS device flags support

Modify the device PM QoS core code to support PM QoS flags requests.

First, add a new field of type struct pm_qos_flags called "flags"
to struct dev_pm_qos for representing the list of PM QoS flags
requests for the given device.  Accordingly, add a new "type" field
to struct dev_pm_qos_request (along with an enum for representing
request types) and a new member called "flr" to its data union for
representig flags requests.

Second, modify dev_pm_qos_add_request(), dev_pm_qos_update_request(),
the internal routine apply_constraint() used by them and their
existing callers to cover flags requests as well as latency
requests.  In particular, dev_pm_qos_add_request() gets a new
argument called "type" for specifying the type of a request to be
added.

Finally, introduce two routines, __dev_pm_qos_flags() and
dev_pm_qos_flags(), allowing their callers to check which PM QoS
flags have been requested for the given device (the caller is
supposed to pass the mask of flags to check as the routine's
second argument and examine its return value for the result).

Subject: [PATCH 0281/3298] console: implement lockdep support for console_lock

Dave Airlie recently discovered a locking bug in the fbcon layer,
where a timer_del_sync (for the blinking cursor) deadlocks with the
timer itself, since both (want to) hold the console_lock:

https://lkml.org/lkml/2012/8/21/36

Unfortunately the console_lock isn't a plain mutex and hence has no
lockdep support. Which resulted in a few days wasted of tracking down
this bug (complicated by the fact that printk doesn't show anything
when the console is locked) instead of noticing the bug much earlier
with the lockdep splat.

Hence I've figured I need to fix that for the next deadlock involving
console_lock - and with kms/drm growing ever more complex locking
that'll eventually happen.

Now the console_lock has rather funky semantics, so after a quick irc
discussion with Thomas Gleixner and Dave Airlie I've quickly ditched
the original idead of switching to a real mutex (since it won't work)
and instead opted to annotate the console_lock with lockdep
information manually.

There are a few special cases:
- The console_lock state is protected by the console_sem, and usually
  grabbed/dropped at _lock/_unlock time. But the suspend/resume code
  drops the semaphore without dropping the console_lock (see
  suspend_console/resume_console). But since the same thread that did
  the suspend will do the resume, we don't need to fix up anything.

- In the printk code there's a special trylock, only used to kick off
  the logbuffer printk'ing in console_unlock. But all that happens
  while lockdep is disable (since printk does a few other evil
  tricks). So no issue there, either.

- The console_lock can also be acquired form irq context (but only
  with a trylock). lockdep already handles that.

This all leaves us with annotating the normal console_lock, _unlock
and _trylock functions.

And yes, it works - simply unloading a drm kms driver resulted in
lockdep complaining about the deadlock in fbcon_deinit:

Subject: [PATCH 0282/3298] tty: prevent unnecessary work queue lock checking
 on flip buffer copy

When low_latency flag is set the TTY receive flip buffer is copied to the
line discipline directly instead of using a work queue in the background.
Therefor only in case a workqueue is actually used for copying data to the
line discipline we'll have to flush the workqueue.

This prevents unnecessary spin lock/unlock on the workqueue spin lock that
can cause additional scheduling overhead on a PREEMPT_RT system. On a 200
MHz AT91SAM9261 processor setup this fixes about 100us of scheduling
overhead on the TTY read call.

The goal is to stop setting and using tty->driver_data in devpts code.
It should be used solely by the driver's code, pty in this case.

First, here we remove TTY from devpts_get_tty and rename it to
devpts_get_priv. Note we do not remove type safety, we just shift the
[implicit] (void *) cast one layer up.

index was unused in devpts_get_tty, so remove that from the prototype
too.

The goal is to stop setting and using tty->driver_data in devpts code.
It should be used solely by the driver's code, pty in this case.

For the cleanup of layering, we will need the inode created in
devpts_pty_new to be stored into slave's driver_data. So we convert
devpts_pty_new to return the inode or an ERR_PTR-encoded error in case
of failure.

The move of 'inode = new_inode(sb);' from declarators to the code is
only cosmetical, but it makes the code easier to read.

The goal is to stop setting and using tty->driver_data in devpts code.
It should be used solely by the driver's code, pty in this case.

Now driver_data are managed only in the pty driver. devpts_pty_new is
switched to accept what we used to dig out of tty_struct, i.e. device
node number and index.

This also removes a note about driver_data being set outside of the
driver.

Subject: [PATCH 0287/3298] TTY: move devpts kill to pty

Now that we have control over tty->driver_data in pty, we can just
kill the /dev/pts/ in pty code too. Namely, in ->shutdown hook of
tty. For pty, this is called only once, for whichever end is closed
last. But we don't care, both driver_data are the inode as it used to
be till now.

Subject: [PATCH 0288/3298] TTY: vt, fix paste_selection ldisc handling

There used to be a single tty_ldisc_ref_wait. But then, when a
big-tty-mutex (BTM) was introduced, it has to be tty_ldisc_ref +
tty_unlock + tty_ldisc_ref_wait + tty_lock. Later, BTM was removed
from that path and tty_ldisc_ref + tty_ldisc_ref_wait remained there.
But it makes no sense now. So leave there only tty_ldisc_ref_wait.

And when we have a reference to an ldisc, actually use it in the loop.
Otherwise it may be racy.

Subject: [PATCH 0289/3298] TTY: ldisc, wait for idle ldisc in release

We reintroduced tty_ldisc_wait_idle in 100eeae2c5c (TTY: restore
tty_ldisc_wait_idle) and used in set_ldisc. Then we added it also to
the hangup path in 92f6fa09bd453 (TTY: ldisc, do not close until there
are readers). And we noted that there is one more path:
~   Before 65b770468e98 tty_ldisc_wait_idle was called also from
~   tty_ldisc_release. It is called from tty_release, so I don't think
~   we need to restore that one.

Well, I was wrong. There might still be holders of an ldisc
reference. Not from userspace, but drivers. If they take a reference
and a user closes the device immediately after that, we have a
problem. ldisc is halted and closed by TTY, but the driver still may
call some ldisc's operation and cause a crash.

So restore the tty_ldisc_wait_idle call also to the third location
where it was before 65b770468e98 (tty-ldisc: turn ldisc user count
into a proper refcount). Now we should be safe with respect to the
ldisc reference counting as all* tty_ldisc_close paths are safely
called with reference count of one.

* Not the one in tty_ldisc_setup's fail path. But that is called
  before the first open finishes. So userspace does not see it yet.
  Even thought the driver is given the TTY already via ->install, it
  should not take a reference to the ldisc yet. If some driver is to
  do this, we should put one tty_ldisc_wait_idle also in the setup.

Subject: [PATCH 0290/3298] TTY: hci_ldisc, remove invalid check in open

hci_ldisc's open checks if tty_struct->disc_data is set. And if so it
returns with an error. But nothing ensures disc_data to be NULL. And
since ld->ops->open shall be called only once, we do not need the
check at all. So remove it.

Note that this is not an issue now, but n_tty will start using the
disc_data pointer and this invalid 'if' would trigger then rendering
TTYs over BT unusable.

Subject: [PATCH 0291/3298] TTY: n_tty, simplify read_buf+echo_buf allocation

ldisc->open and close are called only once and cannot cross. So the
tests in open and close are superfluous. Remove them. (But leave sets
to NULL to ensure there is not a bug somewhere.)

And when the tests are gone, handle properly failures in open. We
leaked read_buf if allocation of echo_buf failed before. Now this is
not the case anymore.

Subject: [PATCH 0292/3298] TTY: n_tty, remove bogus checks

* BUG_ON(!tty) in n_tty_set_termios -- it cannot be called with tty ==
  NULL. It is called from two call sites. First, from n_tty_open where
  we have a valid tty. Second, as ld->ops->set_termios from
  tty_set_termios. But there we have a valid tty too.
* if (!tty) in n_tty_open -- why would the TTY layer call ldisc's
  open with an invalid TTY? No it indeed does not. All call sites have
  a tty and dereference that.
* BUG_ON(!tty->read_buf) in n_tty_read -- this used to be a valid
  check. The ldisc handling was broken some time ago when I added the
  check to ensure everything is OK. It still can catch the case, but
  no later than we move the buffer to ldisc data. Then there will be
  no read_buf in tty_struct, i.e. nothing to check for.
* if (!tty->read_buf) in n_tty_receive_buf -- this should never
  happen. All callers of ldisc->ops->receive_ops should hold a
  reference to an ldisc and close (which frees read_buf) cannot be
  called until the reference is dropped.
* if (WARN_ON(!tty->read_buf)) in n_tty_read -- the same as in the
  previous case.

Subject: [PATCH 0293/3298] TTY: audit, stop accessing tty->icount

This is a private member of n_tty. Stop accessing it. Instead, take is
as an argument.

This is needed to allow clean switch of the private members to a
separate private structure of n_tty.

Subject: [PATCH 0295/3298] TTY: move ldisc data from tty_struct: simple
 members

Here we start moving all the n_tty related bits from tty_struct to
the newly defined n_tty_data struct in n_tty proper.

In this patch primitive members and bits are moved. The rest will be
done per-partes in the next patches.

Subject: [PATCH 0296/3298] TTY: move ldisc data from tty_struct: bitmaps

Here we move bitmaps and use DECLARE_BITMAP to declare them in the new
structure. And instead of memset, we use bitmap_zero as it is more
appropriate.

Subject: [PATCH 0298/3298] TTY: move ldisc data from tty_struct: locks

atomic_write_lock is not n_tty specific, so move it up in the
tty_struct.

And since these are the last ones to move, remove also the comment
saying there are some ldisc' members. There are none now.

In some funtions we need only n_tty_data, so pass it down directly in
case tty is not needed there.

Subject: [PATCH 0300/3298] TTY: move TTY_FLUSH* flags to tty_port

They are only TTY buffers specific. And the buffers will go to
tty_port in the next patches. So to remove the need to have both
tty_port and tty_struct at some places, let us move the flags to
tty_port.

Subject: [PATCH 0301/3298] TTY: tty_buffer, cache pointer to tty->buf

During the move of tty buffers from tty_struct to tty_port, we will
need to switch all users of buf to tty->port->buf. There are many
functions where this is accessed directly in their code many times.
Cache the tty->buf pointer in such functions now and change only
single lines in each function in the next patch.

Not that it is convenient for the next patch, but the code is now also
more readable.

Subject: [PATCH 0302/3298] TTY: add port -> tty link

For that purpose we have to temporarily introduce a second tty back
pointer into tty_port. It is because serial layer, and maybe others,
still do not use tty_port_tty_set/get. So that we cannot set the
tty_port->tty to NULL at will now.

Yes, the fix would be to convert whole serial layer and all its users
to tty_port_tty_set/get. However we are in the process of removing the
need of tty in most of the call sites, so this would lead to a
duplicated work.

Instead we have now tty_port->itty (internal tty) which will be used
only in flush_to_ldisc. For that one it is ensured that itty is valid
wherever the work is run. IOW, the work is synchronously cancelled
before we set itty to NULL and also before hangup is processed.

After we need only tty_port and not tty_struct in most code, this
shall be changed to tty_port_tty_set/get and itty removed completely.

MIME-Version: 1.0

So this is it. The big step why we did all the work over the past
kernel releases. Now everything is prepared, so nothing protects us
from doing that big step.

            ~~~   ~~          ``              ~~~   ~~
The buffers are now in the tty_port structure and we can start
teaching the buffer helpers (insert char/string, flip etc.) to use
tty_port instead of tty_struct all around.

Commit 2be350fa (MIPS: Alchemy: use the ehci platform driver) and commit
e223a4cc (MIPS: Alchemy: use the OHCI platform driver) have change the Alchemy
platform code to register an EHCI and OHCI platform driver, the defconfig file
must thus be accordingly updated to build these drivers by default.

Subject: [PATCH 0308/3298] rcu: Fix comment about _rcu_barrier()/orphanage
 exclusion

In the old days, _rcu_barrier() acquired ->onofflock to exclude
rcu_send_cbs_to_orphanage(), which allowed the latter to avoid memory
barriers in callback handling.  However, _rcu_barrier() recently started
doing get_online_cpus() to lock out CPU-hotplug operations entirely, which
means that the comment in rcu_send_cbs_to_orphanage() that talks about
->onofflock is now obsolete.  This commit therefore fixes the comment.

Subject: [PATCH 0312/3298] rcu: Add a module parameter to force use of
 expedited RCU primitives

There have been some embedded applications that would benefit from
use of expedited grace-period primitives.  In some ways, this is
similar to synchronize_net() doing either a normal or an expedited
grace period depending on lock state, but with control outside of
the kernel.

This commit therefore adds rcu_expedited boot and sysfs parameters
that cause the kernel to substitute expedited primitives for the
normal grace-period primitives.

[ paulmck: Add trace/event/rcu.h to kernel/srcu.c to avoid build error.
	   Get rid of infinite loop through contention path.]

The fix introduced by a10d206e (rcu: Fix day-one dyntick-idle
stall-warning bug) has a C-language precedence error.  It turns out
that this error is harmless in that the same result is computed for all
inputs, but the code is nevertheless a potential source of confusion.
This commit therefore introduces parentheses in order to force the
execution of the code to reflect the intent.

Subject: [PATCH 0316/3298] rcu: Print remote CPU's stacks in stall warnings

The RCU CPU stall warnings rely on trigger_all_cpu_backtrace() to
do NMI-based dump of the stack traces of all CPUs.  Unfortunately, a
number of architectures do not implement trigger_all_cpu_backtrace(), in
which case RCU falls back to just dumping the stack of the running CPU.
This is unhelpful in the case where the running CPU has detected that
some other CPU has stalled.

This commit therefore makes the running CPU dump the stacks of the
tasks running on the stalled CPUs.

Subject: [PATCH 0318/3298] rcu: Dump number of callbacks in stall warning
 messages

In theory, if a grace period manages to get started despite there being
no callbacks on any of the CPUs, all CPUs could go into dyntick-idle
mode, so that the grace period would never end.  This commit updates
the RCU CPU stall warning messages to detect this condition by summing
up the number of callbacks on all CPUs.

Subject: [PATCH 0319/3298] PM / QoS: Make it possible to expose PM QoS device
 flags to user space

Define two device PM QoS flags, PM_QOS_FLAG_NO_POWER_OFF
and PM_QOS_FLAG_REMOTE_WAKEUP, and introduce routines
dev_pm_qos_expose_flags() and dev_pm_qos_hide_flags() allowing the
caller to expose those two flags to user space or to hide them
from it, respectively.

After the flags have been exposed, user space will see two
additional sysfs attributes, pm_qos_no_power_off and
pm_qos_remote_wakeup, under the device's /sys/devices/.../power/
directory.  Then, writing 1 to one of them will update the
PM QoS flags request owned by user space so that the corresponding
flag is requested to be set.  In turn, writing 0 to one of them
will cause the corresponding flag in the user space's request to
be cleared (however, the owners of the other PM QoS flags requests
for the same device may still request the flag to be set and it
may be effectively set even if user space doesn't request that).

Subject: [PATCH 0320/3298] PM / Domains: Check device PM QoS flags in
 pm_genpd_poweroff()

Make the generic PM domains pm_genpd_poweroff() function take
device PM QoS flags into account when deciding whether or not to
remove power from the domain.

After this change the routine will return -EBUSY without executing
the domain's .power_off() callback if there is at least one PM QoS
flags request for at least one device in the domain and at least of
those request has at least one of the NO_POWER_OFF and REMOTE_WAKEUP
flags set.

Subject: [PATCH 0321/3298] PM / ACPI: Take device PM QoS flags into account

Make ACPI power management routines and PCI power management
routines depending on ACPI take device PM QoS flags into account
when deciding what power state to put the device into.

In particular, after this change acpi_pm_device_sleep_state() will
not return ACPI_STATE_D3_COLD as the deepest available low-power
state if PM_QOS_FLAG_NO_POWER_OFF is requested for the device and it
will not require remote wakeup to work for the device in the returned
low-power state if there is at least one PM QoS flags request for the
device, but PM_QOS_FLAG_REMOTE_WAKEUP is not requested for it.

Accordingly, acpi_pci_set_power_state() will refuse to put the
device into D3cold if PM_QOS_FLAG_NO_POWER_OFF is requested for it.

Subject: [PATCH 0323/3298] console: use might_sleep in console_lock

Instead of BUG_ON(in_interrupt()), since that doesn't check for all
the newfangled stuff like preempt.

Note that this is valid since the console_sem is essentially used like
a real mutex with only two twists:
- we allow trylock from hardirq context
- across suspend/resume we lock the logical console_lock, but drop the
  semaphore protecting the locking state.

Now that doesn't guarantee that no one is playing tricks in
single-thread atomic contexts at suspend/resume/boot time, but
- I couldn't find anything suspicious with some grepping,
- might_sleep shouldn't die,
- and I think the upside of catching more potential issues is worth
  the risk of getting a might_sleep backtrace that would have been
  save (and then dealing with that fallout).

Subject: [PATCH 0326/3298] drivers/staging/wlags49_h2/man: remove
 CONFIG_EXPERIMENTAL

This config item has not carried much meaning for a while now and is
almost always enabled by default. As agreed during the Linux kernel
summit, remove it.

Subject: [PATCH 0327/3298] staging: comedi: remove inline alloc_private()

This inline function has a very generic name and it's only a
wrapper around a simple kzalloc(). Since the inline function
does not save any lines-of-code, instead of renaming it just
remove it and do the kzalloc() directly.

From 7fc465b106b40a598d83a0c98d0e8c2a1b4653ff Mon Sep 17 00:00:00 2001
From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Tue, 23 Oct 2012 13:43:11 -0700
Subject: [PATCH 0328/3298] staging: comedi: auto-config drivers do not need to
 set hw_dev

The comedi core now sets the 'hw_dev' pointer in the function
comedi_auto_config_helper() before calling the auto attach
function in the driver.

Remove the now unnecessary call to comedi_set_hw_dev() in the
drivers that use the auto-config attach mechanism.

Subject: [PATCH 0333/3298] staging: comedi: ni_660x: remove inline function
 board()

This function is used to get the dev->board_ptr from the
comedi_device. Remove the function and use a local variable
to hold the pointer where used. Use the comedi_board() helper
to get the pointer.

This BUG_ON can never happen. The 'chan' value comes from the comedi
core in the insn->chanspec and will always be in range for the subdevice
number of channels (s->n_chan = NUM_PFI_CHANNELS).

Subject: [PATCH 0337/3298] staging: comedi: ni_660x: cleanup
 ni_660x_dio_insn_config()

This function handles all the insn_config instructions for the
digital i/o subdevice. These functions are supposed to return
the number of instruction parameters used (insn->n) or an -errno.
Fix the switch() so that the correct result is returned for all
INSN_CONFIG_* cases.

To clarify the code, add a local variable for the 'bit' used with
the instructions used to configure and query the input/output setting
of a channel.

For aesthetic reasons, add a whitespace between each case to improve
readability.

the cpu_base->lock has been unlocked.

Subject: [PATCH 0346/3298] sched: Track the runnable average on a per-task
 entity basis

Instead of tracking averaging the load parented by a cfs_rq, we can track
entity load directly. With the load for a given cfs_rq then being the sum
of its children.

To do this we represent the historical contribution to runnable average
within each trailing 1024us of execution as the coefficients of a
geometric series.

We can express this for a given task t as:

  runnable_sum(t) = \Sum u_i * y^i, runnable_avg_period(t) = \Sum 1024 * y^i
  load(t) = weight_t * runnable_sum(t) / runnable_avg_period(t)

Where: u_i is the usage in the last i`th 1024us period (approximately 1ms)
~ms and y is chosen such that y^k = 1/2.  We currently choose k to be 32 which
roughly translates to about a sched period.

Subject: [PATCH 0348/3298] sched: Aggregate load contributed by task entities
 on parenting cfs_rq

For a given task t, we can compute its contribution to load as:

  task_load(t) = runnable_avg(t) * weight(t)

On a parenting cfs_rq we can then aggregate:

  runnable_load(cfs_rq) = \Sum task_load(t), for all runnable children t

Maintain this bottom up, with task entities adding their contributed load to
the parenting cfs_rq sum.  When a task entity's load changes we add the same
delta to the maintained sum.

Subject: [PATCH 0349/3298] sched: Maintain the load contribution of blocked
 entities

We are currently maintaining:

  runnable_load(cfs_rq) = \Sum task_load(t)

For all running children t of cfs_rq.  While this can be naturally updated for
tasks in a runnable state (as they are scheduled); this does not account for
the load contributed by blocked task entities.

This can be solved by introducing a separate accounting for blocked load:

  blocked_load(cfs_rq) = \Sum runnable(b) * weight(b)

Obviously we do not want to iterate over all blocked entities to account for
their decay, we instead observe that:

  runnable_load(t) = \Sum p_i*y^i

and that to account for an additional idle period we only need to compute:

  y*runnable_load(t).

This means that we can compute all blocked entities at once by evaluating:

  blocked_load(cfs_rq)` = y * blocked_load(cfs_rq)

Finally we maintain a decay counter so that when a sleeping entity re-awakens
we can determine how much of its load should be removed from the blocked sum.

Subject: [PATCH 0350/3298] sched: Add an rq migration call-back to sched_class

Since we are now doing bottom up load accumulation we need explicit
notification when a task has been re-parented so that the old hierarchy can be
updated.

Adds: migrate_task_rq(struct task_struct *p, int next_cpu)

(The alternative is to do this out of __set_task_cpu, but it was suggested that
this would be a cleaner encapsulation.)

Subject: [PATCH 0351/3298] sched: Account for blocked load waking back up

When a running entity blocks we migrate its tracked load to
cfs_rq->blocked_runnable_avg.  In the sleep case this occurs while holding
rq->lock and so is a natural transition.  Wake-ups however, are potentially
asynchronous in the presence of migration and so special care must be taken.

We use an atomic counter to track such migrated load, taking care to match this
with the previously introduced decay counters so that we don't migrate too much
load.

Subject: [PATCH 0353/3298] sched: Compute load contribution by a group entity

Unlike task entities who have a fixed weight, group entities instead own a
fraction of their parenting task_group's shares as their contributed weight.

Compute this fraction so that we can correctly account hierarchies and shared
entity nodes.

Subject: [PATCH 0354/3298] sched: Normalize tg load contributions against
 runnable time

Entities of equal weight should receive equitable distribution of cpu time.
This is challenging in the case of a task_group's shares as execution may be
occurring on multiple cpus simultaneously.

To handle this we divide up the shares into weights proportionate with the load
on each cfs_rq.  This does not however, account for the fact that the sum of
the parts may be less than one cpu and so we need to normalize:
  load(tg) = min(runnable_avg(tg), 1) * tg->shares
Where runnable_avg is the aggregate time in which the task_group had runnable
children.

Subject: [PATCH 0355/3298] sched: Maintain runnable averages across throttled
 periods

With bandwidth control tracked entities may cease execution according to user
specified bandwidth limits.  Charging this time as either throttled or blocked
however, is incorrect and would falsely skew in either direction.

What we actually want is for any throttled periods to be "invisible" to
load-tracking as they are removed from the system for that interval and
contribute normally otherwise.

Do this by moderating the progression of time to omit any periods in which the
entity belonged to a throttled hierarchy.

Subject: [PATCH 0356/3298] sched: Replace update_shares weight distribution
 with per-entity computation

Now that the machinery in place is in place to compute contributed load in a
bottom up fashion; replace the shares distribution code within update_shares()
accordingly.

Subject: [PATCH 0357/3298] sched: Refactor update_shares_cpu() ->
 update_blocked_avgs()

Now that running entities maintain their own load-averages the work we must do
in update_shares() is largely restricted to the periodic decay of blocked
entities.  This allows us to be a little less pessimistic regarding our
occupancy on rq->lock and the associated rq->clock updates required.

Subject: [PATCH 0358/3298] sched: Update_cfs_shares at period edge

Now that our measurement intervals are small (~1ms) we can amortize the posting
of update_shares() to be about each period overflow.  This is a large cost
saving for frequently switching tasks.

Subject: [PATCH 0359/3298] sched: Make __update_entity_runnable_avg() fast

__update_entity_runnable_avg forms the core of maintaining an entity's runnable
load average.  In this function we charge the accumulated run-time since last
update and handle appropriate decay.  In some cases, e.g. a waking task, this
time interval may be much larger than our period unit.

Fortunately we can exploit some properties of our series to perform decay for a
blocked update in constant time and account the contribution for a running
update in essentially-constant* time.

[*]: For any running entity they should be performing updates at the tick which
gives us a soft limit of 1 jiffy between updates, and we can compute up to a
32 jiffy update in a single pass.

C program to generate the magic constants in the arrays:

  #include <math.h>
  #include <stdio.h>

  #define N 32
  #define WMULT_SHIFT 32

  const long WMULT_CONST = ((1UL << N) - 1);
  double y;

  long runnable_avg_yN_inv[N];
  void calc_mult_inv() {
  	int i;
  	double yn = 0;

  	printf("inverses\n");
  	for (i = 0; i < N; i++) {
  		yn = (double)WMULT_CONST * pow(y, i);
  		runnable_avg_yN_inv[i] = yn;
  		printf("%2d: 0x%8lx\n", i, runnable_avg_yN_inv[i]);
  	}
  	printf("\n");
  }

  long mult_inv(long c, int n) {
  	return (c * runnable_avg_yN_inv[n]) >>  WMULT_SHIFT;
  }

  void calc_yn_sum(int n)
  {
  	int i;
  	double sum = 0, sum_fl = 0, diff = 0;

  	/*
  	 * We take the floored sum to ensure the sum of partial sums is never
  	 * larger than the actual sum.
  	 */
  	printf("sum y^n\n");
  	printf("   %8s  %8s %8s\n", "exact", "floor", "error");
  	for (i = 1; i <= n; i++) {
  		sum = (y * sum + y * 1024);
  		sum_fl = floor(y * sum_fl+ y * 1024);
  		printf("%2d: %8.0f  %8.0f %8.0f\n", i, sum, sum_fl,
  			sum_fl - sum);
  	}
  	printf("\n");
  }

  void calc_conv(long n) {
  	long old_n;
  	int i = -1;

  	printf("convergence (LOAD_AVG_MAX, LOAD_AVG_MAX_N)\n");
  	do {
  		old_n = n;
  		n = mult_inv(n, 1) + 1024;
  		i++;
  	} while (n != old_n);
  	printf("%d> %ld\n", i - 1, n);
  	printf("\n");
  }

  void main() {
  	y = pow(0.5, 1/(double)N);
  	calc_mult_inv();
  	calc_conv(1024);
  	calc_yn_sum(N);
  }

Subject: [PATCH 0360/3298] sched: Introduce temporary FAIR_GROUP_SCHED
 dependency for load-tracking

While per-entity load-tracking is generally useful, beyond computing shares
distribution, e.g. runnable based load-balance (in progress), governors,
power-management, etc.

These facilities are not yet consumers of this data.  This may be trivially
reverted when the information is required; but avoid paying the overhead for
calculations we will not use until then.

+ * Fair scheduling class load-balancing methods.
+ *
+ * BASICS
+ *
+ * The purpose of load-balancing is to achieve the same basic fairness the
+ * per-cpu scheduler provides, namely provide a proportional amount of compute
+ * time to each task. This is expressed in the following equation:
+ *
+ *   W_i,n/P_i == W_j,n/P_j for all i,j                               (1)
+ *
+ * Where W_i,n is the n-th weight average for cpu i. The instantaneous weight
+ * W_i,0 is defined as:
+ *
+ *   W_i,0 = \Sum_j w_i,j                                             (2)
+ *
+ * Where w_i,j is the weight of the j-th runnable task on cpu i. This weight
+ * is derived from the nice value as per prio_to_weight[].
+ *
+ * The weight average is an exponential decay average of the instantaneous
+ * weight:
+ *
+ *   W'_i,n = (2^n - 1) / 2^n * W_i,n + 1 / 2^n * W_i,0               (3)
+ *
+ * P_i is the cpu power (or compute capacity) of cpu i, typically it is the
+ * fraction of 'recent' time available for SCHED_OTHER task execution. But it
+ * can also include other factors [XXX].
+ *
+ * To achieve this balance we define a measure of imbalance which follows
+ * directly from (1):
+ *
+ *   imb_i,j = max{ avg(W/P), W_i/P_i } - min{ avg(W/P), W_j/P_j }    (4)
+ *
+ * We them move tasks around to minimize the imbalance. In the continuous
+ * function space it is obvious this converges, in the discrete case we get
+ * a few fun cases generally called infeasible weight scenarios.
+ *
+ * [XXX expand on:
+ *     - infeasible weights;
+ *     - local vs global optima in the discrete case. ]
+ *
+ *
+ * SCHED DOMAINS
+ *
+ * In order to solve the imbalance equation (4), and avoid the obvious O(n^2)
+ * for all i,j solution, we create a tree of cpus that follows the hardware
+ * topology where each level pairs two lower groups (or better). This results
+ * in O(log n) layers. Furthermore we reduce the number of cpus going up the
+ * tree to only the first of the previous level and we decrease the frequency
+ * of load-balance at each level inv. proportional to the number of cpus in
+ * the groups.
+ *
+ * This yields:
+ *
+ *     log_2 n     1     n
+ *   \Sum       { --- * --- * 2^i } = O(n)                            (5)
+ *     i = 0      2^i   2^i
+ *                               `- size of each group
+ *         |         |     `- number of cpus doing load-balance
+ *         |         `- freq
+ *         `- sum over all levels
+ *
+ * Coupled with a limit on how many tasks we can migrate every balance pass,
+ * this makes (5) the runtime complexity of the balancer.
+ *
+ * An important property here is that each CPU is still (indirectly) connected
+ * to every other cpu in at most O(log n) steps:
+ *
+ * The adjacency matrix of the resulting graph is given by:
+ *
+ *             log_2 n     
+ *   A_i,j = \Union     (i % 2^k == 0) && i / 2^(k+1) == j / 2^(k+1)  (6)
+ *             k = 0
+ *
+ * And you'll find that:
+ *
+ *   A^(log_2 n)_i,j != 0  for all i,j                                (7)
+ *
+ * Showing there's indeed a path between every cpu in at most O(log n) steps.
+ * The task movement gives a factor of O(m), giving a convergence complexity
+ * of:
+ *
+ *   O(nm log n),  n := nr_cpus, m := nr_tasks                        (8)
+ *
+ *
+ * WORK CONSERVING
+ *
+ * In order to avoid CPUs going idle while there's still work to do, new idle
+ * balancing is more aggressive and has the newly idle cpu iterate up the domain
+ * tree itself instead of relying on other CPUs to bring it work.
+ *
+ * This adds some complexity to both (5) and (8) but it reduces the total idle
+ * time.
+ *
+ * [XXX more?]
+ *
+ *
+ * CGROUPS
+ *
+ * Cgroups make a horror show out of (2), instead of a simple sum we get:
+ *
+ *                                s_k,i
+ *   W_i,0 = \Sum_j \Prod_k w_k * -----                               (9)
+ *                                 S_k
+ *
+ * Where
+ *
+ *   s_k,i = \Sum_j w_i,j,k  and  S_k = \Sum_i s_k,i                 (10)
+ *
+ * w_i,j,k is the weight of the j-th runnable task in the k-th cgroup on cpu i.
+ *
+ * The big problem is S_k, its a global sum needed to compute a local (W_i)

Subject: [PATCH 0362/3298] perf/x86: Make hardware event translations
 available in sysfs

Add support to display hardware events translations available
through the sysfs. Add 'events' group attribute under the sysfs
x86 PMU record with attribute/file for each hardware event.

This patch adds only backbone for PMUs to display config under
'events' directory. The specific PMU support itself will come
in next patches, however this is how the sysfs group will look
like:

  # ls  /sys/devices/cpu/events/
  branch-instructions
  branch-misses
  bus-cycles
  cache-misses
  cache-references
  cpu-cycles
  instructions
  ref-cycles
  stalled-cycles-backend
  stalled-cycles-frontend

The file - hw event ID mapping is:

  file                      hw event ID
  ---------------------------------------------------------------
  cpu-cycles                PERF_COUNT_HW_CPU_CYCLES
  instructions              PERF_COUNT_HW_INSTRUCTIONS
  cache-references          PERF_COUNT_HW_CACHE_REFERENCES
  cache-misses              PERF_COUNT_HW_CACHE_MISSES
  branch-instructions       PERF_COUNT_HW_BRANCH_INSTRUCTIONS
  branch-misses             PERF_COUNT_HW_BRANCH_MISSES
  bus-cycles                PERF_COUNT_HW_BUS_CYCLES
  stalled-cycles-frontend   PERF_COUNT_HW_STALLED_CYCLES_FRONTEND
  stalled-cycles-backend    PERF_COUNT_HW_STALLED_CYCLES_BACKEND
  ref-cycles                PERF_COUNT_HW_REF_CPU_CYCLES

Each file in the 'events' directory contains the term translation
for the symbolic hw event for the currently running cpu model.

  # cat /sys/devices/cpu/events/stalled-cycles-backend
  event=0xb1,umask=0x01,inv,cmask=0x01

Subject: [PATCH 0363/3298] perf/x86: Filter out undefined events from sysfs
 events attribute

The sysfs events group attribute currently shows all hw events,
including also undefined ones.

This patch filters out all undefined events out of the sysfs events
group attribute, so they don't even show up.

The pmu_lookup should return pmus that do not expose the 'events'
group attribute in sysfs. Also it should fail when any other error
during 'events' lookup is hit (pmu_aliases fails).

Subject: [PATCH 0368/3298] perf tools: Add support to specify hw event as PMU
 event term

Add a way to specify hw event as PMU event term like:

 'cpu/event=cpu-cycles/u'
 'cpu/event=instructions,.../u'
 'cpu/cycles,.../u'

The 'event=cpu-cycles' term is replaced/translated by the hw events
term translation, which is exposed by sysfs 'events' group attribute.

Add parser bits, the rest is already handled by the PMU alias code.

Subject: [PATCH 0369/3298] perf test: Add automated tests for pmu sysfs
 translated events

Add automated tests for all events found under PMU/events
directory. Tested events are in the 'cpu/event=xxx/u' format,
where 'xxx' is substituted by every event found.

The 'event=xxx' term is translated to the cpu specific term.
We only check that the event is created (not the real config
numbers) and that the modifier is properly set.

Subject: [PATCH 0374/3298] gpio/at91: auto request and configure the pio as
 input when the interrupt is used via DT

If we do this

	interrupt-parent = <&pioA>;
	interrupts = <7 0x0>;

The current core map the irq correctly but the gpio is not configured as input.
The pinctrl configure the pin as gpio with the correct mux parameter but is
not responsible to configure it as input.

So do it during the xlate

Subject: [PATCH 0377/3298] perf tools: Try to find cross-built objdump path

As we have architecture information of saved perf.data file, we can try
to find cross-built objdump path.

The triplets include support for Android (arm, x86 and mips
architectures).

Subject: [PATCH 0378/3298] Account the nr_entries in rblist properly

The nr_entries in rblist is never decremented when an element
is deleted. Also, use rblist__remove_node to delete a node in
rblist__delete(). This would keep the nr_entries sane.

Subject: [PATCH 0379/3298] perf tools: Give user better message if precise is
 not supported

Platforms (e.g., VM's) without support for precise mode get a confusing
error message. e.g.,
$ perf record -e cycles:p -a -- sleep 1

  Error: sys_perf_event_open() syscall returned with 95 (Operation not
  supported).  /bin/dmesg may provide additional information.

  No hardware sampling interrupt available. No APIC? If so then you can
  boot the kernel with the "lapic" boot parameter to force-enable it.
  sleep: Terminated

which is not clear that precise mode might be the root problem. With this
patch:

$ perf record -e cycles:p -fo /tmp/perf.data -- sleep 1
  Error:
  'precise' request may not be supported. Try removing 'p' modifier
  sleep: Terminated

v2: softened message to 'may not be' supported per Robert's suggestion

Subject: [PATCH 0382/3298] TTY: Report warning when low_latency flag is
 wrongly used

When a driver has the low_latency flag set and uses the schedule_flip()
function to initiate copying data to the line discipline, a workqueue is
scheduled in but never actually flushed. This is incorrect use of the
low_latency flag (driver should not support the low_latency flag, or use
the tty_flip_buffer_push() function instead). Make sure a warning is
reported to catch incorrect use of the low_latency flag.

This patch goes with: cee4ad1ed90a0959fc29f9d30a2526e5e9522cfa

Subject: [PATCH 0384/3298] serial/8250/8250_early: Prevent rounding error in
 uartclk

Modify divisor to select the nearest baud rate divider rather than the
lowest. It minimizes baud rate errors especially on low UART clock
frequencies.

For example, if uartclk is 33000000 and baud is 115200 the ratio is
about 17.9 The current code selects 17 (5% error) but should select 18
(0.5% error).

This 5% error in baud rate leads to garbage on receiving end, while 0.5%
doesn't.

The issue showed up when using the stock 8250 driver for
Synopsys DW UART. This was on a FPGA with ~12MHz UART clock.
When we enabled early serial, we saw garbage which was narrowed down
to the rounding error.

So the bug had been latent and it only showed up with such low clock rates.

vt8500_port is malloced in vt8500_serial_probe() and should be freed
before leaving from the error handling cases, otherwise it will
cause memory leak.
Fix it by move the allocation of vt8500_port after those test.

 administration

The global "normal" spin lock that guards the line discipline
administration is replaced by a raw spin lock. On a PREEMPT_RT system this
prevents unwanted scheduling overhead around the line discipline administration.

On a 200 MHz AT91SAM9261 processor setup this fixes about 100us of scheduling
overhead on a TTY read or write call.

Subject: [PATCH 0393/3298] tty: serial: KGDB support for PXA

Actually, in order to support KGDB over serial console one must
implement two callbacks for character polling. Clone them from
8250 driver with a bit of tuning.

Subject: [PATCH 0395/3298] serial: clps711x: Convert all static variables to
 dynamic

This patch converts all static variables of clps711x serial driver
to dynamic allocating. In this case we are should remove console_initcall()
and declare console during driver registration. Early kernel messages can
be retrieved by add "earlyprintk" option to the kernel command line.

Subject: [PATCH 0406/3298] perf trace: Support interrupted syscalls

Using the same strategies as in the tmp.perf/trace2, i.e. the 'trace'
tool implemented by tglx, just updated to the current codebase.

Example:

[root@sandy linux]# perf trace usleep 1  | tail
     2.003: mmap(addr: 0, len: 4096, prot: 3, flags: 34, fd: 4294967295, off: 0   ) = -2128396288
     2.017: mmap(addr: 0, len: 4096, prot: 3, flags: 34, fd: 4294967295, off: 0   ) = -2128400384
     2.029: arch_prctl(option: 4098, arg2: 140146949441280, arg3: 140146949435392, arg4: 34, arg5: 4294967295) = 0
     2.084: mprotect(start: 208741634048, len: 16384, prot: 1                     ) = 0
     2.098: mprotect(start: 208735956992, len: 4096, prot: 1                      ) = 0
     2.122: munmap(addr: 140146949447680, len: 91882                              ) = 0
     2.359: brk(brk: 0                                                            ) = 28987392
     2.371: brk(brk: 29122560                                                     ) = 29122560
     2.490: nanosleep(rqtp: 140735694241504, rmtp: 0                              ) = 0
     2.507: exit_group(error_code: 0
[root@sandy linux]#

For now the timestamp and duration are always on, will be selectable.

Also if multiple threads are being monitored, its tid will appear.

The ret output continues to be interpreted a la strace.

Subject: [PATCH 0410/3298] perf trace: Print the name of a syscall when
 failing to read its info

When failing to read the tracepoint event format, like currently with
sys_execve, that is not defined via SYSCALL_DEFINE macros and thus
doesn't have an entry in:

  $ ls -d /sys/kernel/debug/tracing/events/syscalls/sys_enter_*exec*
  /sys/kernel/debug/tracing/events/syscalls/sys_enter_kexec_load
  $

Subject: [PATCH 0411/3298] USB: ezusb: unexport some functions that aren't
 being used
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the ezusb code was split out, support was added for the fx2 chip
type, but no one is using these functions, so comment it out.  If
someone needs it, it can be added back in the future.

Also properly include <linux/usb/ezusb.h> into the ezusb.c file, to
ensure we catch any function prototype mis-matches

Subject: [PATCH 0412/3298] perf tools: Try to build Documentation when
 installing

There's a portion in the "perf list" output refering to the exact
specification of raw hardware events.

Since this description is in the perf-list manpage, try to build and
install the man pages, warning the user when that is not possible
due to missing packages (xmlto and asciidoc).

our USB driver, and those cleanups will remove the need for these

Removing redundant locking

Some last changes in function skel_open and finally commit
52a7499 Revert "USB: usb-skeleton.c: fix open/disconnect race"
introduced a bug in function skel_open, which this patch fixes.

Changes since v2:
- refactoring
- Removing redundant mutex synchronization.

Changes since v1:
- Fixed accordingly feedback of Oliver Neukum oneukum@suse.de: also need to drop the lock.

Subject: [PATCH 0421/3298] USB: EHCI: add condition for delay during the
 resume

Without this condition, all controllers will do this delay,
and increase the resume time.

Only enabled and unsuspended port needs this delay, but
Some buggy hardware(like Synopsys usb controller) will
clear suspend bit once they receive/send resume signal,
so it takes resume bit as consideration.

Tested it at Freescale i.mx6q Sabrelite board.

Subject: [PATCH 0423/3298] USB: EHCI: make ehci_read_frame_index platform
 independent

In preparation for splitting the ehci-hcd driver into a core library
and separate platform-specific driver modules, this patch (as1617)
changes the way ehci_read_frame_index() is handled.

Since the same core library will have to work with both PCI and
non-PCI platforms, the quirk handler routine will be compiled
unconditionally.  The decision about whether to call it or simply to
read the frame index register is made at run time, based on whether
the frame_index_bug quirk flag is set.

Subject: [PATCH 0425/3298] USB: hub_for_each_child should skip unconnected
 ports

This patch (as1619) improves the interface to the "hub_for_each_child"
macro.  The name clearly suggests that the macro iterates over child
devices; it does not suggest that the loop will also iterate over
unnconnected ports.

The patch changes the macro so that it will skip over unconnected
ports and iterate only the actual child devices.  The two existing
call sites are updated to avoid testing for a NULL child pointer,
which is now unnecessary.

Subject: [PATCH 0426/3298] USB: speed up usb_bus_resume()

This patch (as1620) speeds up USB root-hub resumes in the common case
where every enabled port has its suspend feature set (which currently
will be true for every runtime resume of the root hub).  If all the
enabled ports are suspended then resuming the root hub won't resume
any of the downstream devices.  In this case there's no need for a
Resume Recovery delay, because that delay is meant to give devices a
chance to get ready for active use.

To keep track of the port suspend features, the patch adds a
"port_is_suspended" flag to struct usb_device.  This has to be tracked
separately from the device's state; it's entirely possible for a USB-2
device to be suspended while the suspend feature on its parent port is
clear.  The reason is that devices will go into suspend whenever their
parent hub does.

Subject: [PATCH 0430/3298] staging/comedi: Use pr_ or dev_ printks in
 drivers/unioxx5.c

fixed below checkpatch warnings.
- WARNING: Prefer netdev_err(netdev, ... then dev_err(dev, ... then pr_err(...  to printk(KERN_ERR ...
- WARNING: Prefer netdev_info(netdev, ... then dev_info(dev, ... then pr_info(...  to printk(KERN_INFO ...

and added pr_fmt.

-Description: Amplicon 200 Series Digital I/O
-Author: Ian Abbott <abbotti@mev.co.uk>
-Devices: [Amplicon] PC212E (pc212e), PC214E (pc214e), PC215E (pc215e),
-  PCI215 (pci215 or amplc_dio200), PC218E (pc218e), PC272E (pc272e),
-  PCI272 (pci272 or amplc_dio200)
-Updated: Wed, 22 Oct 2008 13:36:02 +0100
-Status: works
-
-Configuration options - PC212E, PC214E, PC215E, PC218E, PC272E:
-  [0] - I/O port base address
-  [1] - IRQ (optional, but commands won't work without it)
-
-Configuration options - PCI215, PCI272:
-  [0] - PCI bus of device (optional)
-  [1] - PCI slot of device (optional)
-  If bus/slot is not specified, the first available PCI device will
-  be used.
-
-Passing a zero for an option is the same as leaving it unspecified.

-Each PPI is a 8255 chip providing 24 DIO channels.  The DIO channels
-are configurable as inputs or outputs in four groups:
-
-  Port A  - channels  0 to  7
-  Port B  - channels  8 to 15
-  Port CL - channels 16 to 19
-  Port CH - channels 20 to 23
-
-Only mode 0 of the 8255 chips is supported.
-
-Each CTR is a 8254 chip providing 3 16-bit counter channels.  Each
-channel is configured individually with INSN_CONFIG instructions.  The
-specific type of configuration instruction is specified in data[0].
-Some configuration instructions expect an additional parameter in
-data[1]; others return a value in data[1].  The following configuration
-instructions are supported:
-
-  INSN_CONFIG_SET_COUNTER_MODE.  Sets the counter channel's mode and
-    BCD/binary setting specified in data[1].
-
-  INSN_CONFIG_8254_READ_STATUS.  Reads the status register value for the
-    counter channel into data[1].
-
-  INSN_CONFIG_SET_CLOCK_SRC.  Sets the counter channel's clock source as
-    specified in data[1] (this is a hardware-specific value).  Not
-    supported on PC214E.  For the other boards, valid clock sources are
-    0 to 7 as follows:
-
-      0.  CLK n, the counter channel's dedicated CLK input from the SK1
-	connector.  (N.B. for other values, the counter channel's CLKn
-	pin on the SK1 connector is an output!)
-      1.  Internal 10 MHz clock.
-      2.  Internal 1 MHz clock.
-      3.  Internal 100 kHz clock.
-      4.  Internal 10 kHz clock.
-      5.  Internal 1 kHz clock.
-      6.  OUT n-1, the output of counter channel n-1 (see note 1 below).
-      7.  Ext Clock, the counter chip's dedicated Ext Clock input from
-	the SK1 connector.  This pin is shared by all three counter
-	channels on the chip.
-
-  INSN_CONFIG_GET_CLOCK_SRC.  Returns the counter channel's current
-    clock source in data[1].  For internal clock sources, data[2] is set
-    to the period in ns.
-
-  INSN_CONFIG_SET_GATE_SRC.  Sets the counter channel's gate source as
-    specified in data[2] (this is a hardware-specific value).  Not
-    supported on PC214E.  For the other boards, valid gate sources are 0
-    to 7 as follows:
-
-      0.  VCC (internal +5V d.c.), i.e. gate permanently enabled.
-      1.  GND (internal 0V d.c.), i.e. gate permanently disabled.
-      2.  GAT n, the counter channel's dedicated GAT input from the SK1
-	connector.  (N.B. for other values, the counter channel's GATn
-	pin on the SK1 connector is an output!)
-      3.  /OUT n-2, the inverted output of counter channel n-2 (see note
-	2 below).
-      4.  Reserved.
-      5.  Reserved.
-      6.  Reserved.
-      7.  Reserved.
-
-  INSN_CONFIG_GET_GATE_SRC.  Returns the counter channel's current gate
-    source in data[2].
-
-Clock and gate interconnection notes:
-
-  1.  Clock source OUT n-1 is the output of the preceding channel on the
-  same counter subdevice if n > 0, or the output of channel 2 on the
-  preceding counter subdevice (see note 3) if n = 0.
-
-  2.  Gate source /OUT n-2 is the inverted output of channel 0 on the
-  same counter subdevice if n = 2, or the inverted output of channel n+1
-  on the preceding counter subdevice (see note 3) if n < 2.
-
-  3.  The counter subdevices are connected in a ring, so the highest
-  counter subdevice precedes the lowest.
-
-The 'INTERRUPT' subdevice pretends to be a digital input subdevice.  The
-digital inputs come from the interrupt status register.  The number of
-channels matches the number of interrupt sources.  The PC214E does not
-have an interrupt status register; see notes on 'INTERRUPT SOURCES'
-below.

-
-When an interrupt source is enabled in the interrupt source enable
-register, a rising edge on the source signal latches the corresponding
-bit to 1 in the interrupt status register.
-
-When the interrupt status register value as a whole (actually, just the
-6 least significant bits) goes from zero to non-zero, the board will
-generate an interrupt.  For level-triggered hardware interrupts (PCI
-card), the interrupt will remain asserted until the interrupt status
-register is cleared to zero.  For edge-triggered hardware interrupts
-(ISA card), no further interrupts will occur until the interrupt status
-register is cleared to zero.  To clear a bit to zero in the interrupt
-status register, the corresponding interrupt source must be disabled
-in the interrupt source enable register (there is no separate interrupt
-clear register).
-
-The PC214E does not have an interrupt source enable register or an
-interrupt status register; its 'INTERRUPT' subdevice has a single
-channel and its interrupt source is selected by the position of jumper
-J5.
-
-COMMANDS
-
-The driver supports a read streaming acquisition command on the
-'INTERRUPT' subdevice.  The channel list selects the interrupt sources
-to be enabled.  All channels will be sampled together (convert_src ==
-TRIG_NOW).  The scan begins a short time after the hardware interrupt
-occurs, subject to interrupt latencies (scan_begin_src == TRIG_EXT,
-scan_begin_arg == 0).  The value read from the interrupt status register
-is packed into a short value, one bit per requested channel, in the
-order they appear in the channel list.

Subject: [PATCH 0434/3298] staging: comedi: amplc_dio200: remove manual
 configuration of PCI boards

Remove the code that allows PCI boards to be manually attached by the
`COMEDI_DEVCONFIG` ioctl (or the "comedi_config" application).
Supported PCI boards will be attached automatically at probe time via
`comedi_pci_auto_config()` and the `attach_pci` hook in the `struct
comedi_driver`.

Subject: [PATCH 0435/3298] staging: comedi: amplc_dio200: no need to
 manipulate PCI ref count

Now that this driver no longer supports "manual" attachment of PCI
devices in its `attach` hook (`dio200_attach()`), it no longer has code
that searches for a suitable PCI device and increments its reference
count.  Since the driver no longer has any reason for incrementing and
decrementing the PCI device's reference count, the calls to
`pci_dev_get()` and `pci_dev_put()` can be removed.

 hw_dev

The call to `comedi_set_hw_dev()` from `dio200_pci_common_attach()` is
now unnecessary since `dio200_pci_common_attach()` is now only called
from this driver's `attach_pci` hook `dio200_attach_pci()` and the
comedi core now calls `comedi_set_hw_dev()` before calling that.  Remove
the unnecessary call.

 'has_clk_gat_sce' from subdevice

The `has_clk_gat_sce` member of `struct dio200_subdev_8254` indicates
whether the board has clock and gate source selection registers.  The
same information can be obtained from read-only board layout data so
doesn't need to be set per '8254' counter subdevice.  Eliminate the
member and use the read-only data instead.  The last parameter of
`dio200_subdev_8254_init()` is used to initialize this member, so remove
that parameter as well.

Subject: [PATCH 0443/3298] staging: comedi: amplc_dio200: use register offsets
 in subdevices

Replace the absolute, modified I/O base addresses in the private data
structures for the '8254' counter and 'intr' DIO subdevices with offsets
from the main I/O base address.  `dio200_subdev_intr_init()` now needs
the offset instead of the absolute address.  `dio200_subdev_8254_init()`
now only needs the offset instead of both the absolute address and the
offset.  The '8255' DIO subdevices are unaffected as they are handled by
the external "8255" module.

This change is not useful by itself but is an intermediate step for
later changes.

Subject: [PATCH 0444/3298] staging: comedi: amplc_dio200: add functions to
 access 8254 counters

Add our own functions to manipulate the '8254' counter chip instead of
the inline ones from "8253.h".  This will make the code less messy when
we add code to support new boards later.

Subject: [PATCH 0445/3298] staging: comedi: amplc_dio200: internalize 8255 DIO
 implementation

Implement the '8255' DIO subdevice internally to this module instead of
using the external "8255" module.  I plan to add support for additional
cards to this driver that would require the I/O callback functionality
of the 8255 module, but the existing callback functions do not have much
context to handle this elegantly.  The additional cards also have extra
DIO features which cannot be handled by the existing "8255" module and
that I'd like to support some time in the future.

The bottom line is I _could_ continue using the "8255" module for a
while with a callback function, but it would turn out to be a very ugly
callback function and I'd have to ditch the use of the "8255" module as
soon as I added an extra feature to the DIO subdevice.

 access functions

Add custom functions to access hardware registers and call them instead
of calling `inb()` and `outb()` directly.  When additional cards are
supported by this driver requiring different register access methods,
the new functions will localize the register access differences to just
these functions.

Subject: [PATCH 0448/3298] staging: comedi: amplc_dio200: set dev->iobase
 before common attach

Don't pass the I/O base address to `dio200_common_attach()`.  The only
thing it does with it is set `dev->iobase` to the passed in value.  Do
that before calling `dio200_common_attach()` in order to simplify
upcoming support for different register access methods.

Subject: [PATCH 0449/3298] staging: comedi: amplc_dio200: support
 memory-mapped I/O

The boards currently supported by this module all use port I/O.  Support
memory-mapped I/O as well for future PCI/PCIe cards.

Define `struct dio200_region` to hold the type of register access and
either the port I/O base address or an ioremapped MMIO address.  Add a
member `io` to the comedi device private data (`struct dio200_private`)
to hold this.  Use this instead of `dev->iobase`.  Memory-mapped
registers are mapped in `dio200_pci_attach()` and unmapped in
`dio200_detach()`.

`dio200_detach()` now uses the private data pointer `devpriv` set to
`dev->private` but can return early if it is `NULL` because no clean-up
needs to be done in that case.

Add `mainbar` member to `struct dio200_board` to hold the PCI BAR number
for the main registers.  This is `2` for the PCI boards currently
supported (PCI215 and PCI272) but will be different for some new boards
to be supported later.

Subject: [PATCH 0451/3298] staging: comedi: amplc_dio200: add min register
 region size in board

Store the length of the main register region in new member `mainsize` of
`struct dio200_board` and initialize it in each element of
`dio200_boards[]`.  For all currently supported boards this is
initialized to `DIO200_IO_SIZE` (0x20), but will be different for newer
boards to be supported in the future.

For ISA boards, this is the actual region length requested, but for PCI
boards it's the minimum expected region length.  Verify that the PCI BAR
region length is sufficient in `dio200_attach_pci()`.

Add `mainshift` member to `struct dio200_board` to hold the amount of
left-shift required for main register offsets.  This is 0 for all the
boards currently supported so it doesn't need initializing explicitly in
any current element of `dio200_boards[]`.  It will be non-zero for some
new boards to be supported by this driver.

Modify the register access functions `dio200_read8()` and
`dio200_write8()` to take the shift into account.

Subject: [PATCH 0453/3298] staging: comedi: amplc_dio200: support PCIe215,
 PCIe236 and PCIe296

Add preliminary support for the above PCIe boards.  The interrupt
subdevice is not working yet as the boards need some additional
initialization to enable interrupts.  Reserve an unused subdevice that
will eventually become a timer subdevice.

Some unused subdevices have been added between the used subdevices on
the PCIe215 and PCIe236.  This is so the subdevice numbers will match a
pattern-matching feature to be added at a later date, where the
pattern-match specifications for a subdevice include pattern-match
results from other subdevices, specified by index.

Subject: [PATCH 0454/3298] staging: comedi: amplc_dio200: allow generation of
 PCIe interrupts

The new PCIe boards PCIe215, PCIe236 and PCIe296 need a special register
setting to allow generation of interrupts on the PCIe bus.  Add
`dio200_pcie_board_setup()` to do this and call it from
`dio200_attach_pci()` for those boards.

Subject: [PATCH 0455/3298] staging: comedi: amplc_dio200: enable enhanced
 features of PCIe boards

The new PCIe boards PCIe215, PCIe236 and PCIe296 have some enhanced
features (over the older boards), although none of these features are
supported by this driver yet.

Enable the enhanced features in hardware and use `dio200_layouts[]` to
indicate which boards support the enhanced features.

One of the enhancements of the new PCIe boards is the addition of extra
clock and gate sources.  Allow clock and gate sources up to 31 for these
boards (compared to 7 for the old boards) although most of those are
reserved for future use.

 read/write of counter

Change the `insn_read` and `insn_write` handlers of the '8254' counter
subdevices to support reading and writing multiple data values.
(Writing multiple values isn't very useful, but if that's what the user
wants....)

Subject: [PATCH 0466/3298] mei: mei_write: revamp error path handling

1. unify common amt and regular error path and use it early in the
  function
2. fix indentation
3. propagate error code directly from copy_from_user
4. print out errors using dev_err instead of dev_dbg

Subject: [PATCH 0468/3298] mei: rename mei_free_cb_private to mei_io_cb_free

1. cb_private was an old name that we depriacated in earlier
cleanups

2. we also group the funcion declaration with other _io_
functions

3. Don't check cb for NULL as mei_io_cb_free is NULL safe

Subject: [PATCH 0470/3298] Add new uio device for dynamic memory allocation

This device extends the uio_pdrv_genirq driver to provide limited
dynamic memory allocation for UIO devices.  This allows UIO devices
to use CMA and IOMMU allocated memory regions. This driver is based
on the uio_pdrv_genirq driver and provides the same generic interrupt
handling capabilities.  Like uio_prdv_genirq,
a fixed number of memory regions, defined in the platform device's
.resources field are exported to userpace. This driver adds the ability
to export additional regions whose number and size are known at boot time,
but whose memory is not allocated until the uio device file is opened for
the first time.  When the device file is closed, the allocated memory block
is freed.  Physical (DMA) addresses for the dynamic regions are provided to
the userspace via /sys/class/uio/uioX/maps/mapY/addr in the same way as
static addresses are when the uio device file is open, when no processes
are holding the device file open, the address returned to userspace is
DMA_ERROR_CODE.

 pc8736x_gpio_cleanup()

platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

since it is #if 0'ed out. It can be added back later if command

Subject: [PATCH 0480/3298] staging: comedi: cb_pcidda: add defines for the PCI
 device ids

The PCI device ids supported by this driver are used multiple
places in the code. To improve maintainability, create #define's
for them.

Subject: [PATCH 0482/3298] staging: comedi: cb_pcidda: remove private data
 variable 'dac'

The private data variable 'dac' is used to hold the PCI base
address for the board. Use the 'iobase' variable provided by
the comedi_device instead.

Subject: [PATCH 0484/3298] staging: comedi: cb_pcidda: remove private data
 variable 'digitalio'

The private data variable 'digitalio' is only used to hold the PCI
base address for the 8255 devices on the board. This value is then
passed to subdev_8255_init() and stored in it's own private data.
There is no need to keep the value in the private data for the board.

The subdev_8255_init() can fail, make sure to check for it.

This board has two 8255 subdevices, one at iobase PCI bar2 and one
at iobase PCI bar2 + 4. Init the subdevices using a for() loop to
make the code a bit more concise.

Subject: [PATCH 0490/3298] staging: comedi: cb_pcidda: remove the private data
 'status'

This variable in the private data is only used to output some
kernel noise during the attach about certian board types not
being fully tested.

All of the boards supported by this driver share a common register
map and should be compatible. Just remove the 'status' and the
noise.

Subject: [PATCH 0501/3298] staging: comedi: addi_common: use
 PCI_VENDOR_ID_ADDIDATA_OLD

The kernel provides this id in pci_ids.h. Use it instead of creating
duplicates of the id with different names.

Subject: [PATCH 0507/3298] staging: comedi: dyna_pci10xx: remove
 PCI_VENDOR_ID_DYNALOG

The PCI chip used on this board is from PLX Technologies Inc. As stated
in the comments of this driver, Dynalog does not have a registered PCI
vendor id so this board uses the PLX vendor id. The kernel provides an
id for that vendor in pci_ids.h (PCI_VENDOR_ID_PLX). Use it instead of
creating a duplicate with a different name.

Subject: [PATCH 0511/3298] edac: Fix the dimm filling for csrows-based layouts

The driver is currently filling data in a wrong way, on drivers
for csrows-based memory controller, when the first layer is a
csrow.

This is not easily to notice, as, in general, memories are
filed in dual, interleaved, symetric mode, as very few memory
controllers support asymetric modes.

While digging into a bug for i82795_edac driver, the asymetric
mode there is now working, allowing us to fill the machine with
4x1GB ranks at channel 0, and 2x512GB at channel 1:

Channel 0 ranks:
EDAC DEBUG: i82975x_init_csrows: DIMM A0: from page 0x00000000 to 0x0003ffff (size: 0x00040000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM A1: from page 0x00040000 to 0x0007ffff (size: 0x00040000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM A2: from page 0x00080000 to 0x000bffff (size: 0x00040000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM A3: from page 0x000c0000 to 0x000fffff (size: 0x00040000 pages)

Channel 1 ranks:
EDAC DEBUG: i82975x_init_csrows: DIMM B0: from page 0x00100000 to 0x0011ffff (size: 0x00020000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM B1: from page 0x00120000 to 0x0013ffff (size: 0x00020000 pages)

Instead of properly showing the memories as such, before this patch, it
shows the memory layout as:

          +-----------------------------------+
          |                mc0                |
          |  csrow0   |  csrow1   |  csrow2   |
----------+-----------------------------------+
channel1: |  1024 MB  |  1024 MB  |   512 MB  |
channel0: |  1024 MB  |  1024 MB  |   512 MB  |
----------+-----------------------------------+

as if both channels were symetric, grouping the DIMMs on a wrong
layout.

After this patch, the memory is correctly represented.
So, for csrows at layers[0], it shows:

          +-----------------------------------------------+
          |                      mc0                      |
          |  csrow0   |  csrow1   |  csrow2   |  csrow3   |
----------+-----------------------------------------------+
channel1: |   512 MB  |   512 MB  |     0 MB  |     0 MB  |
channel0: |  1024 MB  |  1024 MB  |  1024 MB  |  1024 MB  |
----------+-----------------------------------------------+

For csrows at layers[1], it shows:

        +-----------------------+
        |          mc0          |
        | channel0  | channel1  |
--------+-----------------------+
csrow3: |  1024 MB  |     0 MB  |
csrow2: |  1024 MB  |     0 MB  |
--------+-----------------------+
csrow1: |  1024 MB  |   512 MB  |
csrow0: |  1024 MB  |   512 MB  |
--------+-----------------------+

So, no matter of what comes first, the information between
channel and csrow will be properly represented.

Subject: [PATCH 0512/3298] i7300_edac: Fix error flag testing

* Right-shift the values in GET_FBD_FAT_IDX and GET_FBD_NF_IDX, so
  that the callers get the result they expect.
* Fix definition of FERR_FAT_FBD_ERR_MASK.
* Call GET_FBD_NF_IDX, not GET_FBD_FAT_IDX, when operating on
  register FERR_NF_FBD. We were lucky they have the same definition.

This fixes kernel bug #44131:
https://bugzilla.kernel.org/show_bug.cgi?id=44131

Subject: [PATCH 0513/3298] perf tools: Don't stop synthesizing threads when
 one vanishes

The perf_event__synthesize_threads routine synthesizes all the existing
threads in the system, because we don't have any kernel facilities to
ask for PERF_RECORD_{FORK,MMAP,COMM} for existing threads.

It was returning an error as soon as one thread couldn't be synthesized,
which is a bit extreme when, for instance, a forkish workload is
running, like a kernel compile.

Subject: [PATCH 0514/3298] perf trace: Count number of events for each thread
 and globally

The nr_events in trace__run was local, but we will need it in other
trace methods, move it to struct trace.

We'll also need the number of events per thread, so introduce a
nr_events method for that in struct thread_trace.

Subject: [PATCH 0518/3298] OMAPDSS: DSI: fix dsi_get_dsidev_from_id()

If dsi_get_dsidev_from_id() is called with a DSI module id that does not
exist on the board, the function will crash as omap_dss_get_output()
will return NULL.

This happens on omap3 boards when dumping DSI clocks, as the dumping
code will try to get the dsidev for DSI modules 0 and 1, but omap3 only
has DSI module 0.

Also clean up the id -> output mapping, so that if the function is
called with invalid module ID it will return NULL.

Subject: [PATCH 0523/3298] usb: serial: ftdi_sio: Add missing chars_in_buffer
 function

The driver does not wait until the hardware buffer (for data from the PC to the
UART line) is drained when tcdrain or close is called in an application.
Solution: Implement a chars_in_buffer function that checks both the software
and hardware buffer. If the TEMT (TX empty) bit of the line status register
indicates the hw buffer is not empty, let the function return at least 1. This
has been verified to work correctly with an FT232RL. The check on the hw buffer
can not be done for the original SIO device.

Subject: [PATCH 0528/3298] serial: omap: Make context_loss_cnt signed

get_context_loss_count returns an int however it is stored in
unsigned integer context_loss_cnt . This patch tries to make
context_loss_cnt int. So that in case of errors the value
(which may be negative) is not interpreted wrongly.

In serial_omap_runtime_resume in case of errors returned by
get_context_loss_count print a warning and do a restore.

Subject: [PATCH 0529/3298] serial: omap: Remove the default setting of special
 character

Special character detect enable if enabled by default.Received data
comparison with XOFF2 data happens by default.

tty provides only XOFF1 no X0FF2 is provided so no need
to enable check for XOFF2.

Keeping this enabled might give some slow transfers due to dummy xoff2
comparison with xoff2 reset value.

Since not all want the XOFF2 support lets not enable it by
default.

Subject: [PATCH 0532/3298] serial: ifx6x60: different SPI word width configure
 requires different swap process

SPI protocol driver only provide one function (swap_buf()) to swap SPI
data into big endian format, which is only available when SPI
controller's word width is 16 bits. But word width could be configured
as 8/16/32 bits, different word width configure should be mapped to
different swap methods.This patch is to make SPI protocol driver choose
the right swap function corresponding to SPI word width configuration.

This patch make use of mod_timer instead of add_timer in the mrdy_assert function.
Because the srdy interrupter can go high when we are running function mrdy_assert and mrdy_assert
can be called by multi-entry. In our medfield platform, spi stress test can encounter this
error logs triggered by the BUG_ON of add_timer function.This patch had been tested on
our medfield platform.

This patch make use of del_timer instead of del_timer_sync in the

The spi_timer function don't use any resources that may release after

Subject: [PATCH 0538/3298] of serial port driver - add clk_get_rate() support

Currently this driver expects the clock-frequency attribute. This
patch allows getting clock-frequency through clk driver API
clk_get_rate() if clock-frequency attribute is not defined.

So in the device bindings for serial device, one can add clocks
phandle to refer to the clk device to get the rate.

Subject: [PATCH 0541/3298] USB: check port changes before hub runtime suspend
 for some bug device

The hub status endpoint has a long 'bInterval', which is 255ms
for FS/LS device and 256ms for HS device according to USB 2.0 spec,
so the device connection change may be reported later more than 255ms
via status pipe.

The connection change in hub may have been happened already on the
downstream ports, but no status URB completes when it is killed
in hub_suspend(auto), so the connection change may be missed by some
buggy hub devices, which won't generate remote wakeup signal after
their remote wakeup is enabled and they are put into suspend state.

The problem can be observed at least on the below Genesys Logic, Inc.
hub devices:

	0x05e3,0x0606
	0x05e3,0x0608

In theory, there is no way to fix the problem completely, but we
can make it less likely to occur by this patch.

This patch introduces one quirk of HUB_QUIRK_CHECK_PORTS_AUTOSUSPEND
to check ports' change during hub_suspend(auto) for the buggy
devices. If ports' change is found, terminate the auto suspend and
return to working state.

So for the buggy hubs, if the connection change happend before
the ports' check, it can be handled correctly. If it happens between
the ports' check and enabling remote wakeup/entering suspend, it
will be missed. Considered the interval is quite short, it is very
less likely to happen during the window.

Subject: [PATCH 0552/3298] tty, ioctls -- Add new ioctl definitions for tty
 flags fetching

This patch defines new ioctl codes TIOCGPKT, TIOCGPTLCK,
TIOCGEXCL for fetching pty's packet mode and locking state,
and exclusive mode of tty.

[ No real handlers for the codes though, this will be
  addressed in another patch for easier review and
  bisectability ]

Subject: [PATCH 0553/3298] tty: Add get- ioctls to fetch tty status v3

For checkpoint/restore we need to know if tty has
exclusive or packet mode set, as well as if pty
is currently locked. Just to be able to restore
this characteristics.

For this sake the following ioctl codes are introduced

 - TIOCGPKT to get packet mode state
 - TIOCGPTLCK to get Pty locked state
 - TIOCGEXCL to get Exclusive mode state

Note this ioctls are a bit unsafe in terms of data
obtained consistency. The tty characteristics might
be changed right after ioctl complete. Keep it in
mind and use this ioctl carefully.

v2:
 - Use TIOC prefix for ioctl codes (by jslaby@)

Subject: [PATCH 0554/3298] staging: csr: remove panic at locking the mutex

when down_interruptible fail, means a signal occur, or any other failure
we are panicing, and it seems that we should not panic, instead we would
have done a spinlock, but currently removing the panic call.

Subject: [PATCH 0558/3298] powerpc: 52xx: nop out unsupported critical IRQs

Currently, when booting MPC52xx based platforms, we get:

        mpc52xx_irqhost_map: invalid irq: virq=16, l1=0, l2=3
        irq: irq-16==>hwirq-0x3 mapping failed: -22
        [WARNing skipped]

The warning is wrong since the mapping itself is valid. However, there is no
support for that type of IRQ currently. Print a proper warning and bind the irq
to a no_irq chip.

The LPB FIFO interrupt is a peripheral interrupt, thus its L1 cell
has to be 2 instead of 3. Fix it and while at it, move the lpbfifo
node to the common dtsi file.

This patch fixes the irqdomain warning:

Commit 185bae1095188aa199c9be64d6030d8dbfc65e0a ("OMAPDSS: DSS: Cleanup
cpu_is_xxxx checks") broke the DSS clocks configuration by erroneously
using the clock parameters applicable to all other OMAP34xx SoCs for the
OMAP363x. This went unnoticed probably because the cpu_is_omap34xx()
class check wasn't seen as matching the OMAP363x subclass.

Fix it by checking for the OMAP363x subclass before checking for the
OMAP34xx class.

it turns out that current implementation of Mode 1
DMA added a few regressions to some users, so we
need to revert this patch and let author work on
a better version of Mode 1 DMA support.

Subject: [PATCH 0565/3298] gpiolib: add gpio get direction callback support

Add .get_direction callback to gpio_chip. This allows gpiolib
to check the current direction of a gpio.
Used to show the correct gpio direction in sysfs and debug entries.

If callback is not set then gpiolib will work as previously;
e.g. guessing everything is input until a direction is set.

Subject: [PATCH 0567/3298] gpio/tegra: convert to use linear irqdomain

The Tegra driver tries to do the work of irq_domain_add_linear()
by reserving a bunch of descriptors somewhere and keeping track
of the base offset, then calling irq_domain_add_legacy(). Let's
stop doing that and simply use the linear IRQ domain.

For this to work: use irq_create_mapping() in the IRQ iterator
so that the descriptors get allocated here.

Subject: [PATCH 0569/3298] gpio/em: convert to linear IRQ domain

The code in the em driver seems to want to try to do the job of
the linear IRQ domain (allocate descriptors and grab a virtual
range). So why not just use the linear IRQ domain? The code is
now cut down so we don't need isolated functions for this.

Also note that we use irq_create_mapping() to make sure
descriptors are allocated for these IRQs.

Also fixed the FIXME to remove the domain after use.

The special checks for whether we have a base IRQ offset or not
is surplus if we use the simple IRQ domain. The IRQ offset
zero will be interpreted as a linear domain case.

Plus this makes sure we allocate descriptors where need be, or
warn if they are preallocated with SPARSE_IRQ.

Subject: [PATCH 0573/3298] usb: musb: da8xx: use platform_device_unregister in
 da8xx_remove()

platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

 CONFIG_X86_MPPARSE when either ACPI or SFI is present

MPS tables are not needed for systems that have proper ACPI
support. This is also true for systems that have SFI in place.

So this patch allows the configuration (turning off) of
CONFIG_X86_MPPARSE when either ACPI or SFI is present.

Subject: [PATCH 0583/3298] tools lib traceevent: Do not generate dependency
 for system header files

Ingo reported (again!) that 'make clean' on perf/traceevent does not
work due to some reason with system header file. Quotes Ingo:

 "Note that the old dependency related build failure thought to be
  fixed in commit 860df5833e46 is back:

   make[1]: *** No rule to make target
   `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'.  Stop.

  'make clean' itself does not work in libtraceevent:

   comet:~/tip/tools/lib/traceevent> make clean
   make: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'.  Stop.

  So I had to clean it out manually:

   comet:~/tip/tools/lib/traceevent> git ls-files --others | xargs rm
   comet:~/tip/tools/lib/traceevent>

  and then things build fine."

Try to fix it by excluding system headers from dependency generation.

It might be useful to see what's happening behind us rather than just
waiting few seconds during the config checking.

Also align the CHK message with other ones.

Currently checking mmap support in libelf failed due to wrong flags.

    CHK libelf
    CHK libdw

    CHK -DLIBELF_MMAP
/tmp/ccYJwdR0.o: In function `main':

This cannot happen since we checked the elf_begin() when checking
libelf and it succeeded.

Fix it by using a same flag with libelf checking.

Subject: [PATCH 0589/3298] perf inject: Merge sched_stat_* and sched_switch
 events

You may want to know where and how long a task is sleeping. A callchain
may be found in sched_switch and a time slice in stat_iowait, so I add
handler in perf inject for merging this events.

My code saves sched_switch event for each process and when it meets
stat_iowait, it reports the sched_switch event, because this event
contains a correct callchain. By another words it replaces all
stat_iowait events on proper sched_switch events.

I use the next sequence of commands for testing:

  perf record -e sched:sched_stat_sleep -e sched:sched_switch \
	      -e sched:sched_process_exit -g -o ~/perf.data.raw \
	      ~/test-program
  perf inject -v -s -i ~/perf.data.raw -o ~/perf.data
  perf report --stdio -i ~/perf.data

 {
	struct timespec ts1;
	struct timeval tv1;

		ts1.tv_sec = 0;
		ts1.tv_nsec = 10000000;
		nanosleep(&ts1, NULL);

		tv1.tv_sec = 0;
		tv1.tv_usec = 40000;
		select(0, NULL, NULL, NULL,&tv1);
	}
	return 1;

Subject: [PATCH 0591/3298] perf stat: Add --pre and --post command

In order to measure kernel builds, one has to do some pre/post cleanup
work in order to do the repeat build.

So provide --pre and --post command hooks to allow doing just that.

  perf stat --repeat 10 --null --sync --pre 'make -s O=defconfig-build/clean' \
	-- make -s -j64 O=defconfig-build/ bzImage

Subject: [PATCH 0592/3298] UBIFS: fix mounting problems after power cuts

This is a bugfix for a problem with the following symptoms:

1. A power cut happens
2. After reboot, we try to mount UBIFS
3. Mount fails with "No space left on device" error message

UBIFS complains like this:

UBIFS error (pid 28225): grab_empty_leb: could not find an empty LEB

The root cause of this problem is that when we mount, not all LEBs are
categorized. Only those which were read are. However, the
'ubifs_find_free_leb_for_idx()' function assumes that all LEBs were
categorized and 'c->freeable_cnt' is valid, which is a false assumption.

This patch fixes the problem by teaching 'ubifs_find_free_leb_for_idx()'
to always fall back to LPT scanning if no freeable LEBs were found.

This problem was reported by few people in the past, but Brent Taylor
was able to reproduce it and send me a flash image which cannot be mounted,
which made it easy to hunt the bug. Kudos to Brent.

-TODO:
-- support more pcie card reader of Realtek family
-- use kernel coding style
-- checkpatch.pl fixes
-- stop having thousands of lines of code duplicated with staging/rts5139
-- This driver contains an entire SD/MMC stack -- it should use the stack in
-  drivers/mmc instead, as a host driver e.g. drivers/mmc/host/realtek-pci.c;
-  see drivers/mmc/host/via-sdmmc.c as an example.
-- This driver presents cards as SCSI devices, but they should be MMC devices.

This macro relies on a local variable having a specific name.
Remove it and use the comedi_board() helper to get the pointer.

Subject: [PATCH 0605/3298] staging: comedi: dt3000: convert driver to
 attach_pci

Convert this driver to use the comedi PCI auto config mechanism
by adding an attach_pci callback.

Since this driver requires no extra configuration options, and
the attach callback is now optional, remove it.

Remove the kernel noise that is output when the attach fails
for various reasons.

Use the found 'dev->board_name' for the resource name passed to
comedi_pci_enable() and request_irq().

Pass on the error returned from request_irq() instead of returning
-EINVAL on error.

Since this driver no longer walks the pci bus to find the pci_dev,
remove the pci_dev_put() in the detach.

Subject: [PATCH 0613/3298] staging: comedi: dt3000: remove dev_dbg() noise

Remove most of the dev_dbg() output from this driver. Most of it
is just noise.

For now I have left the dev_dbg() in the dt3k_send_cmd() function.
I still have not quite figured out how the low-level i/o works in
this driver...

Subject: [PATCH 0615/3298] staging: comedi: dt3000: change return type of
 dt3k_send_cmd to void

None of the callers check the return value. Just make it a void.

Flip the status check at the end of the function to check for an
error before outputing the dev_dbg(). Use __func__ for the function
name in the message.

Subject: [PATCH 0616/3298] staging: comedi: me_daq: fix pointer dereference in
 me_detach()

As pointed out by Dan Carpenter, dev_private could be NULL when it
is checked before calling comedi_pci_disable(). The private data
variable 'plx_regbase_size' is only used to see if the pci device
has been enabled.

Remove that variable from the private data and just use the unused
dev->iobase variable to let the detach know that the pci device
is enabled.

Subject: [PATCH 0617/3298] staging: comedi: me_daq: cleanup ioremap of PCI bar
 2

PCI bar 2 is the main i/o address for this driver. Currently the
pci_resource_len of the bar is stored in the private data but
it is never used.

Remove 'me_regbase_size' from the private data. Also, remove the
local variables used for the pci_resource_start and _len. Just
pass the values directly to the ioremap().

Remove the kernel noise when the ioremap fails.

Factor out the code in me_attach_pci() that handles the PLX-Bug
workaround to a separate function.

This looks odd. It appears that the bug workaround either swaps
PCI bars 0 and 5 or it modifies PCI bar 0. Shouldn't this happen
before PCI bar 0 is ioremap'ed?

Subject: [PATCH 0628/3298] staging: comedi: me_daq: remove pci_dev_put() in
 detach

This driver uses the comedi auto config mechanism and does not
walk the pci bus to find the pci_dev. It should not be calling
pci_dev_put() to decrement the ref count.

Subject: [PATCH 0629/3298] staging: comedi: me_daq: fix me_ao_insn_read()

This function is supposed to return the analog output value for
a specified channel. The channel number is packed in insn->chanspec,
which is an unsigned int, and unpacked using the CR_CHAN() macro.

Currently this function is trying to use the chanspec as an array.
This works only if a single data value is read.

Fix the function so that the desired channel is determined and all
the data returned is from that channel.

Also, fix the return. The comedi core expects insn_read functions to
return the number of data values (insn->n).

Subject: [PATCH 0631/3298] staging: comedi: me_daq: remove incomplete analog
 input command support

The analog input subdevice functions me_ai_do_cmd_test() and me_ai_do_cmd()
are only stubbed in. They both just return 0.

The me_ai_cancel() function does have code to stop any running conversions
but the me_ai_insn_read() function does that also.

Just remove the incomplete functions and remove SDF_CMD_READ from the
subdevice_flags.

Fix the function so that it checks the instruction, data[0], and
does the correct action based on it.

Subject: [PATCH 0636/3298] staging: comedi: me_daq: cleanup me_dio_insn_bits()

This function only needs to update the output channel state when
the 'mask' (data[0]) indicates that the state is changing. It's
also supposed to return the state for all the input and output
channels in data[1].

This function appears to work correctly but it's coded quite
differently form the other comedi drivers. Rework the function so
it follows the normal form. Also, use a couple local variables
for the mmio addresses used to read/write the dio ports.

Subject: [PATCH 0637/3298] staging: comedi: me_daq: cleanup me_ai_insn_read()

Fix the use of insn->chanspec with the CR_CHAN, CR_RANGE, and CR_AREF
macros. insn->chanspec is an unsigned int not an array.

Cleanup the comments when creating the 'val' to write to the channel
list fifo so that the code is a bit more readable.

Use the 'val' variable when getting the value from the ADC fifo and
then munging the data. This cleans up the goofy line breaks.

This function still does not follow the expectations of the comedi core.
It is supposed to read insn->n values from the channel and return those
values. Currently it only reads a single value.

This seems like a cut and paste bug.  Smatch complains that we don't
allocate enough memory for a set_stakey_rsp struct.  In fact this is
used as a set_assocsta_rsp struct throughout and that also matches the
name of the function.

Subject: [PATCH 0641/3298] Staging: remove telephony drivers

We said we would wait until the 3.6 kernel release to remove these
drivers.  So we waited 6 months longer, that should be fine.

If anyone wants them back, it is trivial to revert these, but given that
I don't think they even build anymore, I doubt anyone will want them.

-Linux Quicknet-Drivers-Howto
-Quicknet Technologies, Inc. (www.quicknet.net)
-Version 0.3.4  December 18, 1999
-
-1.0  Introduction
-
-This document describes the first GPL release version of the Linux
-driver for the Quicknet Internet PhoneJACK and Internet LineJACK
-cards.  More information about these cards is available at
-www.quicknet.net.  The driver version discussed in this document is
-0.3.4.
-
-These cards offer nice telco style interfaces to use your standard
-telephone/key system/PBX as the user interface for VoIP applications.
-The Internet LineJACK also offers PSTN connectivity for a single line
-Internet to PSTN gateway.  Of course, you can add more than one card
-to a system to obtain multi-line functionality.  At this time, the
-driver supports the POTS port on both the Internet PhoneJACK and the
-Internet LineJACK, but the PSTN port on the latter card is not yet
-supported.
-
-This document, and the drivers for the cards, are intended for a
-limited audience that includes technically capable programmers who
-would like to experiment with Quicknet cards.  The drivers are
-considered in ALPHA status and are not yet considered stable enough
-for general, widespread use in an unlimited audience.
-
-That's worth saying again:
-
-THE LINUX DRIVERS FOR QUICKNET CARDS ARE PRESENTLY IN A ALPHA STATE
-AND SHOULD NOT BE CONSIDERED AS READY FOR NORMAL WIDESPREAD USE.
-
-They are released early in the spirit of Internet development and to
-make this technology available to innovators who would benefit from
-early exposure.
-
-When we promote the device driver to "beta" level it will be
-considered ready for non-programmer, non-technical users.  Until then,
-please be aware that these drivers may not be stable and may affect
-the performance of your system.
-
-
-1.1 Latest Additions/Improvements
-
-The 0.3.4 version of the driver is the first GPL release.  Several
-features had to be removed from the prior binary only module, mostly
-for reasons of Intellectual Property rights.  We can't release
-information that is not ours - so certain aspects of the driver had to
-be removed to protect the rights of others.  
-
-Specifically, very old Internet PhoneJACK cards have non-standard
-G.723.1 codecs (due to the early nature of the DSPs in those days).
-The auto-conversion code to bring those cards into compliance with
-today's standards is available as a binary only module to those people
-needing it.  If you bought your card after 1997 or so, you are OK -
-it's only the very old cards that are affected.
-
-Also, the code to download G.728/G.729/G.729a codecs to the DSP is
-available as a binary only module as well.  This IP is not ours to
-release.  
-
-Hooks are built into the GPL driver to allow it to work with other
-companion modules that are completely separate from this module.

-
-2.0  Requirements
-
-2.1  Quicknet Card(s)
-
-You will need at least one Internet PhoneJACK or Internet LineJACK
-cards.  These are ISA or PCI bus devices that use Plug-n-Play for
-configuration, and use no IRQs.  The driver will support up to 16
-cards in any one system, of any mix between the two types.
-
-Note that you will need two cards to do any useful testing alone, since
-you will need a card on both ends of the connection.  Of course, if
-you are doing collaborative work, perhaps your friends or coworkers
-have cards too.  If not, we'll gladly sell them some!
-
-
-2.2  ISAPNP
-
-Since the Quicknet cards are Plug-n-Play devices, you will need the
-isapnp tools package to configure the cards, or you can use the isapnp
-module to autoconfigure them.  The former package probably came with
-your Linux distribution.  Documentation on this package is available
-online at:
-
-http://mailer.wiwi.uni-marburg.de/linux/LDP/HOWTO/Plug-and-Play-HOWTO.html
-
-The isapnp autoconfiguration is available on the Quicknet website at:
-
-    http://www.quicknet.net/develop.htm
-
-though it may be in the kernel by the time you read this.
-
-
-3.0  Card Configuration 
-
-If you did not get your drivers as part of the linux kernel, do the
-following to install them:
-
-   a.  untar the distribution file.  We use the following command:
-        tar -xvzf ixj-0.x.x.tgz
-
-This creates a subdirectory holding all the necessary files.  Go to that
-subdirectory.
-
-   b.  run the "ixj_dev_create" script to remove any stray device
-files left in the /dev directory, and to create the new officially
-designated device files.  Note that the old devices were called 
-/dev/ixj, and the new method uses /dev/phone.  
-
-   c.  type "make;make install" - this will compile and install the
-module.
-
-   d.  type "depmod -av" to rebuild all your kernel version dependencies.
-
-   e.  if you are using the isapnp module to configure the cards
-       automatically, then skip to step f.  Otherwise, ensure that you
-       have run the isapnp configuration utility to properly configure
-       the cards.
-
-       e1. The Internet PhoneJACK has one configuration register that
-           requires 16 IO ports.  The Internet LineJACK card has two
-           configuration registers and isapnp reports that IO 0
-           requires 16 IO ports and IO 1 requires 8.  The Quicknet
-           driver assumes that these registers are configured to be
-           contiguous, i.e. if IO 0 is set to 0x340 then IO 1 should
-           be set to 0x350.
-
-           Make sure that none of the cards overlap if you have
-           multiple cards in the system.
-
-           If you are new to the isapnp tools, you can jumpstart
-           yourself by doing the following:
-
-      e2.  go to the /etc directory and run pnpdump to get a blank
-           isapnp.conf file.
-
-	   	pnpdump > /etc/isapnp.conf
-
-      e3.  edit the /etc/isapnp.conf file to set the IO warnings and
-           the register IO addresses. The IO warnings means that you
-           should find the line in the file that looks like this:
-
-	   (CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
-
-	   and you should edit the line to look like this:
-
-	   (CONFLICT (IO WARNING)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) #
-	   or WARNING
-
-           The next step is to set the IO port addresses.  The issue
-           here is that isapnp does not identify all of the ports out
-           there.  Specifically any device that does not have a driver
-           or module loaded by Linux will not be registered.  This
-           includes older sound cards and network cards.  We have
-           found that the IO port 0x300 is often used even though
-           isapnp claims that no-one is using those ports.  We
-           recommend that for a single card installation that port
-           0x340 (and 0x350) be used.  The IO port line should change
-           from this:
-
-	   (IO 0 (SIZE 16) (BASE 0x0300) (CHECK))
-
-	   to this:
-
-	   (IO 0 (SIZE 16) (BASE 0x0340) )
-
-       e4.  if you have multiple Quicknet cards, make sure that you do
-            not have any overlaps.  Be especially careful if you are
-            mixing Internet PhoneJACK and Internet LineJACK cards in
-            the same system.  In these cases we recommend moving the
-            IO port addresses to the 0x400 block.  Please note that on
-            a few machines the 0x400 series are used.  Feel free to
-            experiment with other addresses.  Our cards have been
-            proven to work using IO addresses of up to 0xFF0.
-
-       e5.  the last step is to uncomment the activation line so the
-            drivers will be associated with the port.  This means the
-            line (immediately below) the IO line should go from this:
-
-            # (ACT Y)
-
-            to this:
-
-	    (ACT Y)
-
-            Once you have finished editing the isapnp.conf file you
-            must submit it into the pnp driverconfigure the cards.
-            This is done using the following command:
-
-	    isapnp isapnp.conf
-
-	    If this works you should see a line that identifies the
-            Quicknet device, the IO port(s) chosen, and a message
-            "Enabled OK".
-
-   f.  if you are loading the module by hand, use insmod.  An example
-of this would look like this:
-
-	insmod phonedev
-	insmod ixj dspio=0x320,0x310 xio=0,0x330
-
-Then verify the module loaded by running lsmod. If you are not using a
-module that matches your kernel version, you may need to "force" the
-load using the -f option in the insmod command.
-
-	insmod phonedev
-	insmod -f ixj dspio=0x320,0x310 xio=0,0x330
-
-
-If you are using isapnp to autoconfigure your card, then you do NOT
-need any of the above, though you need to use depmod to load the
-driver, like this:
-
-	depmod ixj
-
-which will result in the needed drivers getting loaded automatically.
-
-   g.  if you are planning on having the kernel automatically request
-the module for you, then you need to edit /etc/conf.modules and add the
-following lines:
-
-	options ixj dspio=0x340 xio=0x330 ixjdebug=0
-
-If you do this, then when you execute an application that uses the
-module the kernel will request that it is loaded.
-
-  h.  if you want non-root users to be able to read and write to the 
-ixj devices (this is a good idea!) you should do the following:
-
-     - decide upon a group name to use and create that group if 
-       needed.  Add the user names to that group that you wish to 
-       have access to the device.  For example, we typically will
-       create a group named "ixj" in /etc/group and add all users
-       to that group that we want to run software that can use the 
-       ixjX devices.
-
-     - change the permissions on the device files, like this:
-	
-       chgrp ixj /dev/ixj*	
-       chmod 660 /dev/ixj*
-	
-Once this is done, then non-root users should be able to use the
-devices.  If you have enabled autoloading of modules, then the user
-should be able to open the device and have the module loaded
-automatically for them.
-
-
-4.0 Driver Installation problems.
-
-We have tested these drivers on the 2.2.9, 2.2.10, 2.2.12, and 2.2.13 kernels
-and in all cases have eventually been able to get the drivers to load and 
-run.  We have found four types of problems that prevent this from happening.
-The problems and solutions are:
-
-  a. A step was missed in the installation.  Go back and use section 3
-as a checklist.  Many people miss running the ixj_dev_create script and thus
-never load the device names into the filesystem.
-
-  b. The kernel is inconsistently linked.  We have found this problem in
-the Out Of the Box installation of several distributions.  The symptoms 
-are that neither driver will load, and that the unknown symbols include "jiffy"
-and "kmalloc".  The solution is to recompile both the kernel and the
-modules.  The command string for the final compile looks like this:
-
-    In the kernel directory:
-    1.  cp .config /tmp
-    2.  make mrproper
-    3.  cp /tmp/.config .
-    4.	make clean;make bzImage;make modules;make modules_install
-
-This rebuilds both the kernel and all the modules and makes sure they all 
-have the same linkages.  This generally solves the problem once the new 
-kernel is installed and the system rebooted.
-
-  c. The kernel has been patched, then unpatched.  This happens when
-someone decides to use an earlier kernel after they load a later kernel.
-The symptoms are proceeding through all three above steps and still not
-being able to load the driver.  What has happened is that the generated
-header files are out of sync with the kernel itself.  The solution is
-to recompile (again) using "make mrproper".  This will remove and then
-regenerate all the necessary header files.  Once this is done, then you 
-need to install and reboot the kernel.  We have not seen any problem
-loading one of our drivers after this treatment.
-
-5.0  Known Limitations
-
-We cannot currently play "dial-tone" and listen for DTMF digits at the
-same time using the ISA PhoneJACK.  This is a bug in the 8020 DSP chip
-used on that product.  All other Quicknet products function normally
-in this regard.  We have a work-around, but it's not done yet.  Until
-then, if you want dial-tone, you can always play a recorded dial-tone
-sound into the audio until you have gathered the DTMF digits.

 gpio_clps711x_init()

platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

Subject: [PATCH 0651/3298] srcu: Add DEFINE_SRCU()

In old days, we had two different API sets for dynamic-allocated per-CPU
data and DEFINE_PER_CPU()-defined per_cpu data, and because SRCU used
dynamic-allocated per-CPU data, its srcu_struct structures cannot be
declared statically.  This commit therefore introduces DEFINE_SRCU()
and DEFINE_STATIC_SRCU() to allow statically declared SRCU structures,
using the new static per-CPU interfaces.

Subject: [PATCH 0653/3298] rcu: Fix unrecovered RCU user mode in
 syscall_trace_leave()

On x86-64 syscall exit, 3 non exclusive events may happen
looping in the following order:

1) Check if we need resched for user preemption, if so call
schedule_user()

2) Check if we have pending signals, if so call do_notify_resume()

3) Check if we do syscall tracing, if so call syscall_trace_leave()

However syscall_trace_leave() has been written assuming it directly
follows the syscall and forget about the above possible 1st and 2nd
steps.

Now schedule_user() and do_notify_resume() exit in RCU user mode
because they have most chances to resume userspace immediately and
this avoids an rcu_user_enter() call in the syscall fast path.

So by the time we call syscall_trace_leave(), we may well be in RCU
user mode. To fix this up, simply call rcu_user_exit() in the beginning
of this function.

This fixes some reported RCU uses in extended quiescent state.

Subject: [PATCH 0654/3298] ARM: pxa: hx4700: Fix backlight PWM device number

Recent changes to PXA PWM support changed the PXA27X PWM device
numbering scheme.

The linux-3.5 PXA PWM driver followed the hardware numbering scheme for
the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear
numbering scheme:

Address		Hardware	3.5 pwm_id	3.6-rc1 pwm_id
0x40b00000	PWM0		0		0
0x40b00010	PWM2		2		1
0x40c00000	PWM1		1		2
0x40c00010	PWM3		3		3

The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id
must be changed from 1 to 2.

This patch fixes the backlight PWM device number and at the same time
moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

Subject: [PATCH 0655/3298] ARM: pxa/spitz_pm: Fix hang when resuming from STR

Devices that use spitz_pm.c will fail to resume
from STR (Suspend To Ram) when the charger plug is inserted
or removed when a device is in STR mode. The culprit is
a misconfigured gpio line - GPIO18. GPIO18 should be configured as a
regular GPIO input but it gets configured as an alternate function
GPIO18_RDY. And then later in postsuspend() it gets configured as
a regular GPIO18 input line.

Fix this by removing the GPIO18_RDY configuration so that GPIO18
only gets configured as a regular gpio input.

Subject: [PATCH 0665/3298] pinctrl/nomadik: allow to support several ranges
 per GPIO bank

With DB8500 the number of GPIO chips = number GPIO bank =
number of GPIO ranges.

With DB8540, a new GPIO range configuration is used, some GPIO
banks can have several GPIO ranges.

For example, DB8540 GPIO bank0 (GPIO0 to GPIO32) have 2 GPIO
ranges:
    - GPIO0 to GPIO17  : routed
    - GPIO18 to GPIO21 : hole
    - GPIO22 to GPIO28 : routed
    - GPIO29 to GPIO32 : hole

Previously, during nmk_pinctrl_probe(), all GPIO ranges were
parsed, as GPIO ranges are larger than the number of GPIO chips,
a warning occurs. This commit allows each bank to have several
GPIO ranges.

rename from arch/arm/plat-nomadik/include/plat/gpio-nomadik.h
rename to include/linux/platform_data/pinctrl-nomadik.h

From 287f121c8b9535a124397ee880f1dc493a88746a Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Wed, 10 Oct 2012 14:35:17 +0200
Subject: [PATCH 0667/3298] pinctrl/nomadik: merge old pincfg header

This merges the old <plat/pincfg.h> header into
<linux/platform_data/pinctrl-nomadik.h> and rids us of
yet one more <plat/*> include.

Subject: [PATCH 0676/3298] perf tools: Add a global variable "const char
 *input_name"

Currently many perf commands annotate/evlist/report/script/lock etc all
support "-i" option to chose a specific perf data, and all of them
create a local "input_name" to save the file name for that perf data.

Since most of these commands need it, we can add a global variable for
it, also it can some other benefits:

1. When calling script browser inside hists/annotation browser, it needs
to know the perf data file name to run that script.

2. For further feature like runtime switching to another perf data file,
this variable can also help.

Subject: [PATCH 0677/3298] perf script: Add more filter to find_scripts()

As suggested by Arnaldo, many scripts have their own usages and need
capture specific events or tracepoints, so only those scripts whose
target events match the events in current perf data file should be
listed in the script browser menu.

This patch will add the event match checking, by opening "xxx-record"
script to cherry pick out all events name and comparing them with
those inside the perf data file.

Subject: [PATCH 0678/3298] perf scripts browser: Add a browser for perf script

Create a script browser, so that user can check all the available
scripts for current perf data file and run them inside the main perf
report or annotation browsers, for all perf samples or for samples
belong to one thread/symbol.

Please be noted: current script browser is only for report use, and
doesn't cover the record phase, IOW it must run against one existing
perf data file.

The work flow is, users can use function key to list all the available
scripts for current perf data file in system and chose one, which will
be executed with popen("perf script -s xxx.xx",) and all the output
lines are put into one ui browser, pressing 'q' or left arrow key will
make it return to previous browser.

Subject: [PATCH 0681/3298] perf header: Add is_perf_magic() func

With this function, other modules can basically check whether a file is
a legal perf data file by checking its first 8 bytes against all
possible perf magic numbers.

Change the function name from check_perf_magic to more meaningful
is_perf_magic as suggested by acme.

Subject: [PATCH 0682/3298] perf record: Fix mmap error output condition

The mmap_pages default value is not power of 2 (UINT_MAX).

Together with perf_evlist__mmap function returning error value different
from EPERM, we get misleading error message: "--mmap_pages/-m value must
be a power of two."

Fixing this by adding extra check for UINT_MAX value for this error
condition.

Subject: [PATCH 0683/3298] perf python: Initialize 'page_size' variable

The commit 0c1fe6b:

 'perf tools: Have the page size value available for all tools'

Broke the python binding because the global variable 'page_size' is
initialized on the main() routine, that is not called when using
just the python binding, causing evlist.mmap() to fail because it
expects that variable to be initialized to the system's page size.

Fix it by initializing it on the binding init routine.

Subject: [PATCH 0687/3298] clk: Don't return negative numbers for unsigned
 values with !clk

Some of the helper functions return negative error codes if
passed a NULL clock. This can lead to confusing behavior when the
expected return value is unsigned. Fix up these accessors so that
they return unsigned values (or bool in the case of is_enabled).
This way we can't interpret NULL clocks as having valid and
interesting values.

Subject: [PATCH 0690/3298] clk: ux500: Update sdmmc clock to 100MHz for u8500

For u8500 and using 100MHz as the frequency also requires the ape opp 100
voltage, thus use the prcmu_opp_volt_scalable clock type.

Subject: [PATCH 0693/3298] CLK: clk-twl6040: Initial clock driver for OMAP4+
 McPDM fclk clock

On OMAP4+ platforms the functional clock for the McPDM IP is suplied by
the twl6040 codec (bit clock on the PDM bus).
This common clock driver for twl6040 will register the mcpdm_fclk clock to
be used by the McPDM driver to make sure that the needed clocks are
available when needed.

Subject: [PATCH 0695/3298] clk: Common clocks implementation for Versatile
 Express

This patch adds a DT and non-DT based implementation of
the common clock infrastructure for Versatile Express
platform. It registers (statically or using DT) all
required fixed clocks, initialises motherboard's SP810
cell (that provides clocks for SP804 timers) and
explicitly registers VE "osc" driver, to make the
clock generators available early.

Subject: [PATCH 0697/3298] clk: Add devm_clk_{register,unregister}()

Some clock drivers can be simplified if devres takes care of
unregistering any registered clocks along error paths. Introduce
devm_clk_register() so that clock drivers get unregistration for
free along with simplified error paths.

Subject: [PATCH 0700/3298] vtime: Make vtime_account_system() irqsafe

vtime_account_system() currently has only one caller with
vtime_account() which is irq safe.

Now we are going to call it from other places like kvm where
irqs are not always disabled by the time we account the cputime.

So let's make it irqsafe. The arch implementation part is now
prefixed with "__".

vtime_account_idle() arch implementation is prefixed accordingly
to stay consistent.

Subject: [PATCH 0701/3298] kvm: Directly account vtime to system on guest
 switch

Switching to or from guest context is done on ioctl context.
So by the time we call kvm_guest_enter() or kvm_guest_exit()
we know we are not running the idle task.

As a result, we can directly account the cputime using
vtime_account_system().

There are two good reasons to do this:

* We avoid some useless checks on guest switch. It optimizes
a bit this fast path.

* In the case of CONFIG_IRQ_TIME_ACCOUNTING, calling vtime_account()
checks for irq time to account. This is pointless since we know
we are not in an irq on guest switch. This is wasting cpu cycles
for no good reason. vtime_account_system() OTOH is a no-op in
this config option.

* We can remove the irq disable/enable around kvm guest switch in s390.

A further optimization may consist in introducing a vtime_account_guest()
that directly calls account_guest_time().

Subject: [PATCH 0702/3298] cputime: Specialize irq vtime hooks

With CONFIG_VIRT_CPU_ACCOUNTING, when vtime_account()
is called in irq entry/exit, we perform a check on the
context: if we are interrupting the idle task we
account the pending cputime to idle, otherwise account
to system time or its sub-areas: tsk->stime, hardirq time,
softirq time, ...

However this check for idle only concerns the hardirq entry
and softirq entry:

* Hardirq may directly interrupt the idle task, in which case
we need to flush the pending CPU time to idle.

* The idle task may be directly interrupted by a softirq if
it calls local_bh_enable(). There is probably no such call
in any idle task but we need to cover every case. Ksoftirqd
is not concerned because the idle time is flushed on context
switch and softirq in the end of hardirq have the idle time
already flushed from the hardirq entry.

In the other cases we always account to system/irq time:

* On hardirq exit we account the time to hardirq time.
* On softirq exit we account the time to softirq time.

To optimize this and avoid the indirect call to vtime_account()
and the checks it performs, specialize the vtime irq APIs and
only perform the check on irq entry. Irq exit can directly call
vtime_account_system().

CONFIG_IRQ_TIME_ACCOUNTING behaviour doesn't change and directly
maps to its own vtime_account() implementation. One may want
to take benefits from the new APIs to optimize irq time accounting
as well in the future.

Subject: [PATCH 0703/3298] cputime: Separate irqtime accounting from generic
 vtime

vtime_account() doesn't have the same role in
CONFIG_VIRT_CPU_ACCOUNTING and CONFIG_IRQ_TIME_ACCOUNTING.

In the first case it handles time accounting in any context. In
the second case it only handles irq time accounting.

So when vtime_account() is called from outside vtime_account_irq_*()
this call is pointless to CONFIG_IRQ_TIME_ACCOUNTING.

To fix the confusion, change vtime_account() to irqtime_account_irq()
in CONFIG_IRQ_TIME_ACCOUNTING. This way we ensure future account_vtime()
calls won't waste useless cycles in the irqtime APIs.

Subject: [PATCH 0704/3298] staging: csr: remove func_enter macro

this macro is used for debugging purposes,

it actually defined as

if (unifi_debug >= 5) {
	printk("unifi => %s\n", __FUNCTION__);
}

which produces too many of those prints if the unifi_debug is >=5.
remove these calls and the macro itself altogether

Subject: [PATCH 0705/3298] staging: csr: remove func_exit macro

this macro is used for debugging purposes,

it actually defined as

if (unifi_debug >= 5) {
	printk("unifi: <= %s\n", __FUNCTION__);
}

which produces too many of those prints if the unifi_debug is >=5.
remove these calls and the macro itself altogether

Subject: [PATCH 0706/3298] staging: csr: remove func_exit_r macro

this macro is used for debugging purposes,

it actually defined as

if (unifi_debug >= 5) {
	printk("unifi: <= %s %d\n", __FUNCTION__, (int)rc);
}

which produces too many of those prints if the unifi_debug is >=5.
remove these calls and the macro itself altogether

Subject: [PATCH 0711/3298] staging/rtl8192e: Fix compile warning 'is static
 but declared in .. which is not static'

When compiling this driver I get these compile warnings:

function 'rtllib_is_empty_essid' which is not static [enabled by

rtllib.h:2620:3: warning: '______f' is static but declared in inline

These functions are declared as extern inline but not 'overloaded'
anywhere so we can declare them static inline and get rid of the
warnings.

 issue

Fix a coccinelle warning catched by Fengguang's 0-DAY system:
+ drivers/staging/dgrp/dgrp_net_ops.c:1061:11-27: ERROR: nd is NULL but dereferenced.

Put the "done:" label a bit down would solve this issue.

Subject: [PATCH 0715/3298] staging: comedi: change type of auto-config context

Change the type of the context parameter passed to
`comedi_auto_config_helper()` from `void *` to `unsigned long`.  It's
currently just an internal change and all current internal usages pass
pointers in the context, but future uses of this function may pass
integer values or pointer values at the whim of a lower-level comedi
driver and the `unsigned long` type expresses this better as it is
commonly used in the Linux kernel to hold such values.

Subject: [PATCH 0716/3298] staging: comedi: rename old auto-config functions

Rename `comedi_auto_config()` to `comedi_old_auto_config()`, and
`comedi_auto_config_wrapper()` to `comedi_old_auto_config_wrapper()`.
These functions are deprecated and will be removed once the few
remaining low-level comedi drivers that use them have been updated.
(The low-level drivers in question support auto-configuration of
detected comedi devices, but still use the `attach()` hook in their
`struct comedi_driver` to do so.)

This internal change frees up the name `comedi_auto_config` for future
use.

Subject: [PATCH 0717/3298] staging: comedi: add generic auto-config functions

Add (and export) generic auto-config function `comedi_auto_config()` to
allow hardware devices on arbitrary bus types (e.g. platform devices,
spi devices, etc.) to be auto-configured as comedi devices.  This uses a
new `auto_attach()` hook in the `struct comedi_driver`.  This new hook
will eventually replace the bus-specific `attach_pci()` and
`attach_usb()` hooks in the low-level comedi drivers.

When the `auto_attach()` hook is called in the low-level driver, the
`hw_dev` member of the `struct comedi_device` will have already been set
to the hardware device passed to `comedi_auto_config()`.  The low-level
driver can convert this to some bus-device wrapper structure pointer,
possibly with the help of the `context` parameter that is passed
unchanged from the `comedi_auto_config()` call.

Also export the existing `comedi_auto_unconfig()` function as the
matching call to `comedi_auto_config()`.

Allow `comedi_pci_auto_config()` and `comedi_usb_auto_config()` to use
the new `auto_attach()` hook in the low-level driver's `struct
comedi_driver` if it is set and the `attach_pci()` or `attach_usb()`
hook (for PCI or USB respectively) is `NULL`.

Eventually, the `auto_attach()` hook will be the only way of
auto-configuring hardware devices as comedi devices and the bus-type
specific `attach_pci()` and `attach_usb()` hooks will be removed.

Subject: [PATCH 0725/3298] ARM: OMAP2+: clockdomain: Fix OMAP4 ISS clk domain
 to support only SWSUP

Since CAM domain (ISS) has no module wake-up dependency
with any other clock domain of the device and the dynamic
dependency from L3_main_2 is always disabled, the domain
needs to be in force wakeup in order to be able to access
it for configure (sysconfig) it or use it.

Also since there is no clock in the domain managed automatically
by the hardware, there is no use to configure automatic
clock domain transition. SW should keep the SW_WKUP domain
transition as long as a module in the domain is required to
be functional.

Subject: [PATCH 0726/3298] ARM: OMAP: hwmod: wait for sysreset complete after
 enabling hwmod

When waking up from off-mode, some IP blocks are reset automatically by
hardware. For this reason, software must wait until the reset has
completed before attempting to access the IP block.

This patch fixes for example the bug introduced by commit
6c31b2150ff96755d24e0ab6d6fea08a7bf5c44c ("mmc: omap_hsmmc: remove access
to SYSCONFIG register"), in which the MMC IP block is reset during
off-mode entry, but the code expects the module to be already available
during the execution of context restore.

This version includes a fix from Kevin Hilman <khilman@ti.com> for
GPIO problems on the 37xx EVM - thanks Kevin.

Subject: [PATCH 0732/3298] perf, powerpc: Fix hw breakpoints returning -ENOSPC

I've been trying to get hardware breakpoints with perf to work
on POWER7 but I'm getting the following:

  % perf record -e mem:0x10000000 true

    Error: sys_perf_event_open() syscall returned with 28 (No space left on device).  /bin/dmesg may provide additional information.

    Fatal: No CONFIG_PERF_EVENTS=y kernel support configured?

  true: Terminated

(FWIW adding -a and it works fine)

Debugging it seems that __reserve_bp_slot() is returning ENOSPC
because it thinks there are no free breakpoint slots on this
CPU.

I have a 2 CPUs, so perf userspace is doing two perf_event_open
syscalls to add a counter to each CPU [1].  The first syscall
succeeds but the second is failing.

On this second syscall, fetch_bp_busy_slots() sets slots.pinned
to be 1, despite there being no breakpoint on this CPU.  This is
because the call the task_bp_pinned, checks all CPUs, rather
than just the current CPU. POWER7 only has one hardware
breakpoint per CPU (ie. HBP_NUM=1), so we return ENOSPC.

The following patch fixes this by checking the associated CPU
for each breakpoint in task_bp_pinned.  I'm not familiar with
this code, so it's provided as a reference to the above issue.

FYI, there are new sparse warnings:

This patch makes it static and also adds the static keyword to

'events_sysfs_show' was not declared.

Subject: [PATCH 0734/3298] x86/ce4100: Fix pm_poweroff

The CE4100 platform is currently missing a proper pm_poweroff
implementation leading to poweroff making the CPU spin forever
and the CE4100 platform does not enter a low-power mode where
the external Power Management Unit can properly power off the
system. Power off on this platform is implemented pretty much
like reboot, by writing to the SoC built-in 8051 microcontroller
mapped at I/O port 0xcf9, the value 0x4.

The default reboot is via ACPI for this platform, and the CEFDK
bootloader actually supports this, but will issue a system power
off instead of a real reboot. Setting the reboot method to be
KBD instead of ACPI ensures proper system reboot.

Subject: [PATCH 0736/3298] x86/ce4100: Fix PCI configuration register access
 for devices without interrupts

Some CE4100 devices such as the:

 - DFX module (01:0b.7)
 - entertainment encryption device (01:10.0)
 - multimedia controller (01:12.0)

do not have a device interrupt at all.

This patch fixes the PCI controller code to declare the missing
PCI configuration register space, as well as a fixup method for
forcing the interrupt pin to be 0 for these devices. This is
required to ensure that pci drivers matching on these devices
will be able to honor the various PCI subsystem calls touching
the configuration space.

Subject: [PATCH 0737/3298] sched/autogroup: Fix crash on reboot when autogroup
 is disabled

Due to these two commits:

  8323f26ce342 sched: Fix race in task_group()
  800d4d30c8f2 sched, autogroup: Stop going ahead if autogroup is disabled

... autogroup scheduling's dynamic knobs are wrecked.

With both patches applied, all you have to do to crash a box is
disable autogroup during boot up, then reboot.. boom, NULL pointer
dereference due to 800d4d30 not allowing autogroup to move things,
and 8323f26ce making that the only way to switch runqueues.

Remove most of the (dysfunctional) knobs and turn the remaining
sched_autogroup_enabled knob readonly.

If the user fiddles with cgroups hereafter, once tasks
are moved, autogroup won't mess with them again unless
they call setsid().

No knobs, no glitz, nada, just a cute little thing folks can
turn on if they don't want to muck about with cgroups and/or
systemd.

Subject: [PATCH 0739/3298] perf header: Fix numa topology printing

Andrew reported that the commit 7e94cfcc9d20 ("perf header: Use pre-
processed session env when printing") regresses the header output.  It
was because of a missed string pointer calculation in the loop.

Subject: [PATCH 0740/3298] perf tools: Fix strbuf_addf() when the buffer needs
 to grow

This was found during chasing down the header output regression.  The
strbuf_addf() was checking buffer length with a result of vscnprintf()
which cannot be greater than that of strbuf_avail().

Since numa topology and pmu mapping info in header were converted to use
strbuf, it sometimes caused uninteresting behaviors with the broken
strbuf.

Fix it by using vsnprintf() which returns desired output string length
regardless of the available buffer size and grow the buffer if needed.

Subject: [PATCH 0757/3298] Staging: bcm: Remove typedef for
 stLocalSFChangeIndicationAlt and call directly.

This patch removes typedef for
stLocalSFChangeIndicationAlt, changes the
name of the struct to bcm_change_indication,
and removes a comment. In addition, any
calls to typedef stLocalSFChangeIndicationAlt
are changed to call the struct directly.

Subject: [PATCH 0763/3298] staging: comedi: rtd520: cleanup pci bar ioremap

Use the size returned by pci_resource_len() when ioremap'ing the
pci bars instead of assuming a size.

Factor the common code that does the low-level reset of the board
out of rtd_init_board() and rtc_detach().

Fix the if test in rtd_detach() before doing the reset, devpriv->lcfg
could be NULL at this point.

Subject: [PATCH 0767/3298] staging: comedi: rtd520: remove broken USE_DMA code

It appears the dma code in this driver is seriously broken.
Enabling USE_DMA causes the driver to not even compile.

Just remove all the dma code for now.

Subject: [PATCH 0769/3298] staging: comedi: rtd520: convert driver to
 attach_pci

Convert this driver to use the comedi PCI auto config mechanism
by adding an attach_pci callback.

Since this driver requires no extra configuration options, and
the attach callback is now optional, remove it.

Use the found 'dev->board_name' for the resource name passed to
comedi_pci_enable() and request_irq().

Since this driver no longer walks the pci bus to find the pci_dev,
remove the pci_dev_put() in the detach.

Subject: [PATCH 0771/3298] staging: comedi: rtd520: remove DPRINTK messages

These are all development debug messages. A lot of them are in
the interrupt routine and probably shouldn't be there. Some of
the others are actually commented out.

Just remove all of them.

Subject: [PATCH 0772/3298] staging: comedi: rtd520: remove 'intCount' from the
 private data

This variable is cleared when an ai command is initiated and then
incremented with each interrupt. Other than that it's never used.
Just remove it.

Subject: [PATCH 0774/3298] staging: comedi: rtd520: allow attaching without
 interrupt support

Interrupts ares only required for the ai subdevice command support.

Allow the driver to attach to the board even if request_irq() fails.
Only hook up the command support if the interrupt is available.

Subject: [PATCH 0785/3298] staging: comedi: addi_common: move module init code
 to EOF

Move the module_{init,exit} code and associated variables to the end
of the file.

Use module_comedi_pci_driver() to remove the module init boilerplate.

For aesthetic reasons, rename the comedi_driver and pci_driver from
driver_* to *_driver.

Remove the forward declarations for i_ADDI_{Attach,Detach}.

Subject: [PATCH 0786/3298] staging: comedi: addi-data: move the main
 #include's to the drivers

The addi-data drivers are all built by the main driver files including
addi-data/addi_common.c. That file then includes other files depending
on what driver is being compiled. This is makes the code quite messy
and hard to follow.

Start cleaning it up by removing the unneeded #include's in addi_common.c
and moving the some of the comedi #include's into the individual driver
files.

This is the first step in getting rid of the #ifdef'ery in addi_common.c.

Subject: [PATCH 0788/3298] staging: comedi: addi-data: remove the addi-data
 #include ifdef'ery

Move the addi-data specific #include's from addi_common.h to the
individual driver files.

The apci-1710, apci-3200, and apci-3300 drivers still have floating
point code in them and are currently disabled in the Kconfig and
Makefile. For now, move the fpu_{begin,end} functions from addi_common.c
to the main driver file so we can get rid of the #ifdef'ery.

From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Mon, 29 Oct 2012 16:52:20 -0700
Subject: [PATCH 0789/3298] staging: comedi: addi-data: remove the
 MODULE_DEVICE_TABLE #ifdef'ery

Move the MODULE_DEVICE_TABLE for each addi-data driver from addi_common.c
to the individual driver files. This removes the need #ifdef'ery.

Subject: [PATCH 0790/3298] staging: comedi: addi-data: remove the boardinfo
 #ifdef'ery

Move the boardinfo for each addi-data driver from addi_common.c to
the individual driver files. This removes the need #ifdef'ery.

Subject: [PATCH 0791/3298] staging: comedi: addi_common: remove the extra
 cruft

The individual addi-data files all define ADDIDATA_DRIVER_NAME. Remove
the #ifndef/#define for it in addi_common.c.

Remove the commented out MODULE_* stuff. The individual addi-data drivers
have this information.

Remove the, badly formatted, function comments. The functions are
obvious.

Subject: [PATCH 0810/3298] staging: comedi: addi_eeprom: make
 v_EepromWaitBusy() static

This function is only used in this file. Move it to remove the need
for the forward declaration.

Also, remove the comment about an error in the data book. It's not
really an error just someones misunderstanding about doing a byte
read of a dword register.

Move them to remove the need for the forward declarations.

Also, remove some of the more obvious comments and fix a couple coding

From aa36c7720aa65417a992c9722a2ee34c74572d50 Mon Sep 17 00:00:00 2001
From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Mon, 29 Oct 2012 17:03:36 -0700
Subject: [PATCH 0812/3298] staging: comedi: addi_eeprom: make the eeprom
 helper functions static

The functions used to read the eeprom header information blocks are
only used in this file. Move them to remove the need for the forward
declarations.

The i_EepromReadTimerHeader() function is currently not being used.
Block it out with and #if 0/#endif until it's determined if it should
be removed.

Subject: [PATCH 0813/3298] staging: comedi: addi_eeprom: remove the last
 forward declarations

None of the functions in this file are exported. Make them static and
remove the unnecessary forward declarations.

Subject: [PATCH 0814/3298] staging: comedi: addi_eeprom: rename
 'dw_Address'/'w_PCIBoardEepromAddress'

This variable is actually the PCI bar 0 i/o address of the device found
with pci_resource_start().

For aesthetic reasons, rename it to 'iobase' and change to type to an
unsigned long.

Subject: [PATCH 0815/3298] staging: comedi: addi_eeprom: rename
 'pc_PCIChipInformation'

This variable is the pointer to the string name of the eeprom type
found on the board. This name comes from the boardinfo of the
driver.

For aesthetic reasons, rename it to simply 'type'.

 v_EepromCs76Read()

Add namespace to the function by renaming the CamelCase function to
addi_eeprom_read_93c76().

Change the return type of the function to unsigned short and just
return the read value instead of passing it through a pointer.

Rename the CamelCase parameters and local variables.

Make addi_eeprom_cmd_93c76() return the last value so it does not
need to be calculated.

Rename the EE_READ and EE76_CMD_LEN defines so they have namespace
associated with the other 93c76 defines.

Cleanup the loop that reads the eeprom bits so it's a bit more concise.

Subject: [PATCH 0824/3298] staging: comedi: addi_eeprom: move the eeprom
 offset to addi_eeprom_readw()

All the addi_eeprom_readw() calls have the offset to the start of user
data (0x100) as part of the address calculation. Create a define for this
constant and move it's addition to the address into addi_eeprom_readw().

Subject: [PATCH 0825/3298] staging: comedi: addi_eeprom: cleanup
 i_EepromReadMainHeader()

Consolidate the two loops used to read the main header data and the
individual function header data from the eeprom.

The structs used to read the main header are not used outside this
function so remove them by reading the eeprom data into local
variables used in the loop.

Consolidate the 'timer' function cases.

 i_EepromReadDigitalInputHeader()

Add namespace by renaming this CamelCase function to
addi_eeprom_read_di_info().

Refactor the function so that it stores the data from the eeprom directly
in the private data instead of using the a struct to pass the data back
to i_EepromReadMainHeader(). This allows removing the str_DigitalInputHeader
struct.

Leave the reads of the unused eeprom data for now.

The return value is always 0 and it's never checked. Change it to void.

 i_EepromReadTimerHeader()

Use this function to set the private data instead of doing it in the
i_EepromReadMainHeader() function. Keep the eeprom read code #if 0'ed
out for now.

Add namespace by renaming this CamelCase function to
addi_eeprom_read_timer_info().

Remove the unused str_TimerMainHeader and str_TimerDetails structs.

The return value is always 0 and it's never checked. Change it to void.

Subject: [PATCH 0831/3298] staging: comedi: addi_eeprom: cleanup
 i_EepromReadMainHeader()

Add namespace by renaming this CamelCase function to
addi_eeprom_read_info().

Remove the 'type' parameter. This parameter is a char pointer to the
string name of the eeprom type used on the board. This can be found
when needed using the dev pointer.

Change the parameter order so that the comedi_device pointer is passed
first.

The return value is always 0 and it's never checked. Change it to void.

Subject: [PATCH 0836/3298] staging: comedi/drivers: use auto_attach instead of
 attach_usb

Change the usbdux, usbduxfast and usbduxsigma drivers to use the new
`auto_attach()` method instead of the `attach_usb()` method.  I plan to
remove the `attach_usb()` and `attach_pci()` methods from `struct
comedi_driver` once nothing is using them.

From 750af5e568d060ec6994cdcb4e86cdddfcd473c0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0837/3298] staging: comedi/drivers: use auto_attach instead of
 attach_pci

Change comedi drivers for PCI boards to use the new `auto_attach()`
method instead of the `attach_pci()` method.  I plan to remove the
`attach_pci()` and `attach_usb()` methods from `struct comedi_driver`
once nothing is using them.

Tag the functions with `__devinit` where they are not already so tagged,
as they are only called during PCI probe.

so no point in getting userspace's hopes up.

Subject: [PATCH 0844/3298] Tools: hv: Don't return loopback addresses

Don't return loopback addresses and further don't terminate
the IP address strings with a semicolon. This is the current
behavior of Windows guests.

Subject: [PATCH 0845/3298] PM / QoS: Fix the return value of
 dev_pm_qos_update_request()

Commit e39473d (PM / QoS: Make it possible to expose PM QoS device
flags to user space) introduced __dev_pm_qos_update_request() to be
called internally by dev_pm_qos_update_request(), but forgot to make
the latter actually use the return value of the former.  Fix this
mistake.

Subject: [PATCH 0847/3298] staging: et131x: Refactor nic_rx_pkts() to remove
 indenting

In nic_rx_pkts() some large chunks of code are indented in 'if (len)'
sections. Refactor the code to remove these indents and re-join longer
split lines.

Subject: [PATCH 0849/3298] staging: et131x: Remove unnecessary NULL pointer
 assignments

During a previous refactoring excerise, two NULL pointer assingments
were moved to their respective pointer declarations. Dan Carpenter
correctly points out that these assignments are not needed.
Removing them.

Also two small whitespace changes - rejoining split lines, as they are
now less than 80 chars.

Subject: [PATCH 0850/3298] staging: et131x: Remove unnecessary PHY register
 write

The PHY registers are now being controlled from the connected phydev,
so there shouldn't be any reason for the et131x code to perform any
extra setup. Removing the interrupt setup code, and register defines
that are now unused.

On testing, no changes in behaviour were experienced.

theres no point in checking the col variable,
its always zero, and wont print a new line, actually
its better to have a new line after a set of characters
printed, instead of confusing with the concatenated
characters when called multiple times at a time.

-  NAME
-  CsrLogLevelTextSet
-
-  DESCRIPTION
-  Set the text logging level for a given origin and optionally sub origin
-  by name. If either string is NULL or zero length, it is interpreted as
-  all origins and/or all sub origins respectively. If originName is NULL
-  or zero length, subOriginName is ignored.
-
-  Passing NULL or zero length strings in both originName and subOriginName
-  is equivalent to calling CsrLogLevelTextSetAll, and overrides all
-  previous filter configurations for all origins and sub origins.
-
-  Passing NULL or a zero length string in subOriginName overrides all
-  previous filter configurations for all sub origins of the specified
-  origin.
-
-Note: the supplied strings may be accessed after the function returns
-and must remain valid and constant until CsrLogDeinit is called.
-
-Note: when specifying an origin (originName is not NULL and not zero
-length), this function can only be used for origins that use the
-csr_log_text_2.h interface for registration and logging. Filtering for
-origins that use the legacy csr_log_text.h interface must be be
-configured using the legacy filter configuration functions that accept
-a CsrLogTextTaskId as origin specifier. However, when not specifying an
-origin this function also affects origins that have been registered with
-the legacy csr_log_text.h interface. Furthermore, using this function
-and the legacy filter configuration functions on the same origin is not
-allowed.
-
-PARAMETERS
-originName - a string containing the name of the origin. Can be NULL or
-zero length to set the log level for all origins. In this case, the
-subOriginName parameter will be ignored.
-subOriginName - a string containing the name of the sub origin. Can be
-NULL or zero length to set the log level for all sub origins of the
-specified origin.
-warningLevelMask - The desired log level for the specified origin(s) and
-sub origin(s).

Subject: [PATCH 0860/3298] USB: fix build with XEN and EARLY_PRINTK_DBGP
 enabled but USB_SUPPORT disabled

Since there's no possible caller of dbgp_external_startup() and
dbgp_reset_prep() when !USB_EHCI_HCD, there's no point in building and
exporting these functions in that case. This eliminates a build error
under the conditions listed in the subject, introduced with the merge
f1c6872e4980bc4078cfaead05f892b3d78dea64.

Subject: [PATCH 0864/3298] USB: fix build with XEN and EARLY_PRINTK_DBGP
 enabled but USB_SUPPORT disabled

Since there's no possible caller of dbgp_external_startup() and
dbgp_reset_prep() when !USB_EHCI_HCD, there's no point in building and
exporting these functions in that case. This eliminates a build error
under the conditions listed in the subject, introduced with the merge
f1c6872e4980bc4078cfaead05f892b3d78dea64.

When rts51x_read_status() returns USB_STOR_TRANSPORT_ERROR,
an error happens. This patch fixes build warning as below:

Subject: [PATCH 0876/3298] serial: jsm: Convert jsm_printk to jsm_dbg

These printks should all be emitted at KERN_DEBUG level.
Make them dependent on CONFIG_DEBUG or (#define DEBUG)
simplify the code a bit.

Add missing newlines where appropriate.

Most all of these messages could be deleted too.

Subject: [PATCH 0877/3298] serial: 8250_pci: use module_pci_driver to simplify
 the code

Use the module_pci_driver() macro to make the code simpler
by eliminating module_init and module_exit calls.

dpatch engine is used to auto generate this patch.

Subject: [PATCH 0878/3298] uart: update the sysfs handler to use uart_get_info

The two patches needed are now in the tree. The first added the sysfs
interface and directly accesses the uartclk. The second provides a
proper interface for getting the values.

Wire them together.

This formes a basis for both get and set methods for any of the other uart
properties and we can now fill them out further.

Subject: [PATCH 0879/3298] uart: tidy the uart_get_info API

We pass both port and state because the original caller had both to hand.
With all the attribute callers this won't be true so do the conversion in
the function itself.

The current callers all do lock/query/unlock. This won't be true for future
set based cases but there are plenty of get ones that will exist so split
the code with a helper for the future cases.

+ * which
+ *   -checks-if-tty-buffer-has-char-to-send
+ *   -writes-data-to-uart
+ *   -enable-tx-intr
+ *
+ * Once data bits are pushed out, controller raises the Tx-room-avail-Interrupt.
+ * The first thing Tx ISR does is disable further Tx interrupts (as this could
+ * be the last char to send, before settling down into the quiet polled mode).
+ * It then calls the exact routine used by tty layer write to send out any
+ * more char in tty buffer. In case of sending, it re-enables Tx-intr. In case

Subject: [PATCH 0882/3298] x86/mce: Do not change worker's running cpu in
 cmci_rediscover().

cmci_rediscover() used set_cpus_allowed_ptr() to change the current process's
running cpu, and migrate itself to the dest cpu. But worker processes are not
allowed to be migrated. If current is a worker, the worker will be migrated to
another cpu, but the corresponding  worker_pool is still on the original cpu.

In this case, the following BUG_ON in try_to_wake_up_local() will be triggered:
BUG_ON(rq != this_rq());

This will cause the kernel panic. The call trace is like the following:

This patch removes the set_cpus_allowed_ptr() call, and put the cmci rediscover
jobs onto all the other cpus using system_wq. This could bring some delay for
the jobs.

If an attempt is made to transmit a packet that is over the device's
MTU then we log it using the datapath's name.  However, it is much
more helpful to use the device name instead.

Subject: [PATCH 0884/3298] openvswitch: Store flow key len if ARP opcode is
 not request or reply.

We currently only extract the ARP payload if the opcode indicates
that it is a request or reply.  However, we also only set the
key length in these situations even though it should still be
possible to match on the opcode.  There's no real reason to
restrict the ARP opcode since all have the same format so this
simply removes the check.

Subject: [PATCH 0889/3298] staging:iio: Consolidate adt7310 and adt7410 driver

The adt7310 is the SPI version of the adt7410, so there is no need to have a
separate driver for it. The register map layout is a bit different, i.e. the
addresses of the register differ, but the individual register layouts are
identical. We solve this by adding a small look-up table, which translates
adt7410 register addresses to ad7310 register addresses.

Subject: [PATCH 0892/3298] ARM: OMAP2+: hwmod: add flag to prevent hwmod code
 from touching IP block during init
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add HWMOD_EXT_OPT_MAIN_CLK flag to indicate that this IP block is
dependent on an off-chip functional clock that is not guaranteed to be
present during initialization.  IP blocks marked with this flag are
left in the INITIALIZED state during kernel init.

This is a workaround for a hardware problem.  It should be possible to
guarantee that at least one clock source will be present and active
for any IP block's main functional clock.  This ensures that the hwmod
code can enable and reset the IP block.  Resetting the IP block during
kernel init prevents any bogus bootloader, ROM code, or previous OS
configuration from affecting the kernel.  Hopefully a clock
multiplexer can be added on future SoCs.

N.B., at some point in the future, it should be possible to query the
clock framework for this type of information.  Then this flag should
no longer be needed.

Subject: [PATCH 0893/3298] ARM: OMAP4: hwmod data: do not enable or reset the
 McPDM during kernel init
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolve this kernel boot message:

omap_hwmod: mcpdm: cannot be enabled for reset (3)

The McPDM on OMAP4 can only receive its functional clock from an
off-chip source.  This source is not guaranteed to be present on the
board, and when present, it is controlled by I2C.  This would
introduce a board dependency to the early hwmod code which it was not
designed to handle.  Also, neither the driver for this off-chip clock
provider nor the I2C code is available early in boot when the hwmod
code is attempting to enable and reset IP blocks.  This effectively
makes it impossible to enable and reset this device during hwmod init.

At its core, this patch is a workaround for an OMAP hardware problem.
It should be possible to configure the OMAP to provide any IP block's
functional clock from an on-chip source.  (This is true for almost
every IP block on the chip.  As far as I know, McPDM is the only
exception.)  If the kernel cannot reset and configure IP blocks, it
cannot guarantee a sane SoC state.  Relying on an optional off-chip
clock also creates a board dependency which is beyond the scope of the
early hwmod code.

This patch works around the issue by marking the McPDM hwmod record
with the HWMOD_EXT_OPT_MAIN_CLK flag.  This prevents the hwmod
code from touching the device early during boot.

Subject: [PATCH 0902/3298] usb: gadget: network: fix bind() error path

I think this is wrong since 72c973dd ("usb: gadget: add
usb_endpoint_descriptor to struct usb_ep"). If we fail to allocate an ep
or bail out early we shouldn't check for the descriptor which is
assigned at ep_enable() time.

This function works only on FS or HS. If the gadget is HS capable only
HS descriptors are assigned. If we plug it to an 1.1 host it won't work
because we have only 2.0 descriptors. This patch changes the behavior to
provide both sets.

Subject: [PATCH 0907/3298] usb: gadget: uvc: fix error path in
 uvc_function_bind()

The "video->minor = -1" assigment is done in V4L2 by
video_register_device() so it is removed here.
Now. uvc_function_bind() calls in error case uvc_function_unbind() for
cleanup. The problem is that uvc_function_unbind() frees the uvc struct
and uvc_bind_config() does as well in error case of usb_add_function().
Removing kfree() in usb_add_function() would make the patch smaller but
it would look odd because the new allocated memory is not cleaned up.
However it is not guaranteed that if we call usb_add_function() we also
get to the bind function.
Therefore the patch extracts the conditional cleanup from
uvc_function_unbind() applies to uvc_function_bind().
uvc_function_unbind() now contains only the complete cleanup which is
required once everything has been registrated.

Subject: [PATCH 0908/3298] usb: gadget: always update HS/SS descriptors and
 create a copy of them

HS and SS descriptors are staticaly created. They are updated during the
bind process with the endpoint address, string id or interface numbers.

After that, the descriptor chain is linked to struct usb_function which
is used by composite in order to serve the GET_DESCRIPTOR requests,
number of available configs and so on.

There is no need to assign the HS descriptor only if the UDC supports
HS speed because composite won't report those to the host if HS support
has not been reached. The same reasoning is valid for SS.

This patch makes sure each function updates HS/SS descriptors
unconditionally and uses the newly introduced helper function to create a
copy the descriptors for the speed which is supported by the UDC.

While at that, also rename f->descriptors to f->fs_descriptors in order
to make it more explicit what that means.

Subject: [PATCH 0909/3298] usb: gadget: remove DMA_ADDR_INVALID from f_uac2
 and gadgetfs

DMA_ADDR_INVALID is used by the UDC driver and the gadgets should
provide only a buffer address. Everything else should be taken core of
by the UDC and udc-core.

Subject: [PATCH 0910/3298] usb: gadget: uac2: provide a variable for interface
 and alt settings

This patch removes the shifting and masking of interface and its alt
setting and provides its own variable.

This looks better and is smaller:

Subject: [PATCH 0912/3298] usb: gadget: let f_* use usb_string_ids_tab() where
 it makes sense

Instead of calling usb_string_id() multiple times I replace it with one
usb_string_ids_tab(). The NULL pointer in struct usb_string with "" and
are not overwritten in fail or unbind case.

The conditional assignment remains because some gadgets recycle the string
ID because the same descriptor (and string ID) is used if we have more
than one config descriptor.

Subject: [PATCH 0913/3298] usb: gadget: dummy_hdc: prepare for multiple
 instances

This patch replaces the single pdev variable by an array. One change:
The device id is no longer -1 (i.e. none) but 0.
This is prepation work for multiple instances of the dummy_hcd + udc
which should help to test gadget framework with multiple UDCs.

Subject: [PATCH 0914/3298] usb: gadget: dummy_hcd: add setup / cleanup of
 multiple HW intances

This patch creates & adds multiple instances of the HCD and UDC. We have
a new module option "num" which says how many emulated UDCs + HCDs we
want. The default value is one and currently the maximum is one as well.
This will change soon.

Subject: [PATCH 0915/3298] usb: gadget: dummy_hcd: remove global
 the_controller variable

The one thing that makes two UDCs+HCDs impossible is the global
the_controller variable. This patch changes this. After device
allocation we allocate the "the_controller" variable and pass it as
platform_data to the UDC and its companion.
We can have now multiple instances dummy hcd and therefore I change the
limit from one to two. I was able to test this with g_ncm adn g_zero:

|# lsusb
|Bus 001 Device 002: ID 0525:a4a0 Netchip Technology, Inc. Linux-USB "Gadget Zero"
|Bus 002 Device 002: ID 0525:a4a1 Netchip Technology, Inc. Linux-USB Ethernet Gadget
|Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
|Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I was able to start testusb -a and ifconfig usb[01] up with no complains.

Subject: [PATCH 0916/3298] usb: dwc3: remove custom unique id handling

The lockless implementation of the unique id is quite impressive (:P)
but dirver's core can handle it, we can remove it and make our code a
little smaller.

Subject: [PATCH 0917/3298] usb: musb: read MUSB_POWER register only when
 required.

This is part of the workaround for AM35x advisory Advisory 1.1.20.
The advisory says that the IPSS bridge can't handle 8 & 16 bit read
access. An 8bit read access to MUSB_POWER results in an 32bit read
access which also reads INTRTX and therefore may lose interrupts.
This patch tries to minimize reads to MUSB_POWER and perform them only
when required.

Subject: [PATCH 0918/3298] usb: musb: avoid FADDR read access

This is part of the workaround for AM35x advisory Advisory 1.1.20.
The advisory says that the IPSS bridge can't handle 8 & 16 bit read
access. An 8bit read access to FADDR results in an 32bit read
access which also reads INTRTX and therefore may lose interrupts.
This patch removes any reads to FADDR as they are not really required.

Subject: [PATCH 0921/3298] perf tools: Warn about missing libelf

When perf detects no libelf during the build, it'll use internal mini
elf parser instead of libelf.  But as it only supports minimal
functionalities, it also disables support to 'probe' builtin command.

Currently it didn't warned to user.  Fix it.

Subject: [PATCH 0922/3298] perf tools: Add info about cross compiling for
 Android ARM

Without defining ARCH=arm, building perf for Android ARM will fail,
because it needs architecture specific files.

So add related relevant information to the android documentation.

Subject: [PATCH 0923/3298] perf tools: Speed up the perf build time by
 simplifying the perf --version string generation

Building perf is pretty slow on trees that have a lot of commits
relative to the nearest Git tag. This slowness manifests itself during
version string generation:

 $ perf stat --null --repeat 3 --sync --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN
 PERF_VERSION = 3.7.rc3.1458.g5399b3b
 PERF_VERSION = 3.7.rc3.1458.g5399b3b
 PERF_VERSION = 3.7.rc3.1458.g5399b3b

 Performance counter stats for 'util/PERF-VERSION-GEN' (3 runs):

       2.857503976 seconds time elapsed                                          ( +-  0.22% )

The build can be even slower than that, when one over NFS volumes.

The reason for the slowness is that util/PERF-VERSION-GEN uses "git
describe" to generate the string, which has to count the "number of
commits distance" from the nearest tag - the ".1458." count in the
output above. For that Git had to extract and decompress 1458 Git
objects, which takes time and bandwidth.

But this "number of commits" value is mostly irrelevant in practice. We
either want to know an approximate tag name, or we want to know the
precise sha1.

So this patch simplifies the version string to:

 PERF_VERSION = 3.7.rc3.g5399b3b.dirty

which speeds up the version string generation script by an order of
magnitude:

 $ perf stat --null --repeat 3 --sync --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN
 PERF_VERSION = 3.7.rc3.g5399b3b.dirty
 PERF_VERSION = 3.7.rc3.g5399b3b.dirty
 PERF_VERSION = 3.7.rc3.g5399b3b.dirty

Subject: [PATCH 0924/3298] perf tools: Further speed up the perf build

There's another source of overhead in the perf version string generator:

   git update-index -q --refresh

... which will iterate the whole checked out tree. This can be pretty
slow on NFS volumes, but takes some time even with local SSD disks and a
fully cached kernel tree:

 $ perf stat --null --repeat 3 --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN
 PERF_VERSION = 3.7.rc3.g5399b3b.dirty
 PERF_VERSION = 3.7.rc3.g5399b3b.dirty
 PERF_VERSION = 3.7.rc3.g5399b3b.dirty

 Performance counter stats for 'util/PERF-VERSION-GEN' (3 runs):

       0.306999221 seconds time elapsed                                          ( +-  0.56% )

So remove the .dirty differentiator as well - it adds little information
because locally patched git trees are common, but seldom are the perf
tools modified.

So a lot of version strings are reported as 'dirty' while in fact they
are pristine perf builds. For example 99% of my perf builds are not
patched but the kernel tree is slightly patched, which adds the .dirty
tag.

Eliminating that tag speeds up version generation by another order of
magnitude:

 $ perf stat --null --repeat 3 --sync --pre "rm -f PERF-VERSION-FILE" util/PERF-VERSION-GEN
 PERF_VERSION = 3.7.rc3.g4b0bd3
 PERF_VERSION = 3.7.rc3.g4b0bd3
 PERF_VERSION = 3.7.rc3.g4b0bd3

(Also clean up some of the comments around this code.)

Subject: [PATCH 0925/3298] perf tools: Handle --version string generation on
 machines without git

If git is installed we'll have a 'perf --version' output of this form:

$ make -j8 -C tools/perf/ O=/home/acme/git/build/perf install
$ perf --version
perf version 3.7.rc3.g3afad6

Now on a machine without git installed:

$ mv  /home/acme/bin/git /home/acme/bin/git.OFF
$ make -j8 -C tools/perf/ O=/home/acme/git/build/perf install
$ perf --version
perf version 3.7.0-rc2

That is, no error message due to git not being installed will appear on the
screen and instead the version string in the top level Makefile will be
used.

From 52502bf201a85b5b51a384037a002d0b39093df0 Mon Sep 17 00:00:00 2001
From: Jiri Olsa <jolsa@redhat.com>
Date: Wed, 31 Oct 2012 15:52:47 +0100
Subject: [PATCH 0932/3298] perf tests: Add framework for automated
 perf_event_attr tests

The idea is run perf session with kidnapping sys_perf_event_open
function. For each sys_perf_event_open call we store the perf_event_attr
data to the file to be checked later against what we expect.

You can run this by:
  $ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v

v2 changes:
  - preserve errno value in the hook

Subject: [PATCH 0933/3298] USB: serial: remove driver version information

Remove all MODULE_VERSION macros and driver-version information (except
for garmin_gps which uses it in a status reply).

It is the kernel version that matters and not some private version
scheme which rarely even gets updated.

Subject: [PATCH 0934/3298] USB: remove iteration limit in hub_tt_work()

This patch (as1621) removes the limit on the number of loops allowed
in hub_tt_work().  The value is arbitrary, and it's silly to have a
limit in the first place -- anything beyond the limit would not get
handled.

Besides, it's most unlikely that we'll ever need to clear more than a
couple of TT buffers at any time.

Subject: [PATCH 0935/3298] USB: EHCI: remove unused Link Power Management code

This patch (as1622) removes the USB-2.1 Link Power Management code
from the ehci-hcd driver.  This code was never integrated with
usbcore, it is full of bugs, and it was not getting used by anybody.

However, the debugging code for dumping the LPM-related fields in the
EHCI registers is left in place.  In theory it might be useful to see
these values, even though we don't use them.

This essentially amounts to a partial revert of commit
aa4d8342988d0c1a79ff19b2ede1e81dfbb16ea5 (USB: EHCI: EHCI 1.1
addendum: preparation) and an almost full revert of commit
48f24970144479c29b8cee6d2e1dbedf6dcf9cfb (USB: EHCI: EHCI 1.1
addendum: Basic LPM feature support) plus its follow-ons.

Subject: [PATCH 0936/3298] USB: EHCI: remove ehci_port_power() routine

This patch (as1623) removes the ehci_port_power() routine and all the
places that call it.  There's no reason for ehci-hcd to change the
port power settings; the hub driver takes care of all that stuff.

There is one exception: When the controller is resumed from
hibernation or following a loss of power, the ports that are supposed
to be handed over to a companion controller must be powered on first.
Otherwise the handover won't work.  This process is not visible to the
hub driver, so it has to be handled in ehci-hcd.

There are many modems in addition to the D-Link DWM 652
exposing the CD interface in modem mode, and some expose
an integrated card reader as well. Always ignore these
interfaces.

Matching on device and interface class with with unspecified

different from USB_DEVICE_AND_INTERFACE_INFO which requires
the full interface class/subclass/protocol triplet.

Subject: [PATCH 0941/3298] x86, amd: Disable way access filter on Piledriver
 CPUs

The Way Access Filter in recent AMD CPUs may hurt the performance of
some workloads, caused by aliasing issues in the L1 cache.
This patch disables it on the affected CPUs.

The issue is similar to that one of last year:
http://lkml.indiana.edu/hypermail/linux/kernel/1107.3/00041.html
This new patch does not replace the old one, we just need another
quirk for newer CPUs.

The performance penalty without the patch depends on the
circumstances, but is a bit less than the last year's 3%.

The workloads affected would be those that access code from the same
physical page under different virtual addresses, so different
processes using the same libraries with ASLR or multiple instances of
PIE-binaries. The code needs to be accessed simultaneously from both
cores of the same compute unit.

More details can be found here:
http://developer.amd.com/Assets/SharedL1InstructionCacheonAMD15hCPU.pdf

CPUs affected are anything with the core known as Piledriver.
That includes the new parts of the AMD A-Series (aka Trinity) and the
just released new CPUs of the FX-Series (aka Vishera).
The model numbering is a bit odd here: FX CPUs have model 2,
A-Series has model 10h, with possible extensions to 1Fh. Hence the
range of model ids.

Subject: [PATCH 0943/3298] tracing: Allow tracers to start at core initcall

There's times during debugging that it is helpful to see traces of early
boot functions. But the tracers are initialized at device_initcall()
which is quite late during the boot process. Setting the kernel command
line parameter ftrace=function will not show anything until the function
tracer is initialized. This prevents being able to trace functions before
device_initcall().

There's no reason that the tracers need to be initialized so late in the
boot process. Move them up to core_initcall() as they still need to come
after early_initcall() which initializes the tracing buffers.

print_max and use_max_tr in struct tracer are "int" variables and

Subject: [PATCH 0945/3298] ring-buffer: Add a 'dropped events' counter

The existing 'overrun' counter is incremented when the ring
buffer wraps around, with overflow on (the default). We wanted
a way to count requests lost from the buffer filling up with
overflow off, too. I decided to add a new counter instead
of retro-fitting the existing one because it seems like a
different statistic to count conceptually, and also because
of how the code was structured.

Subject: [PATCH 0946/3298] tracing: Expand ring buffer when trace_printk() is
 used

Since tracing is not used by 99% of Linux users, even though tracing
may be configured in, it does not make sense to allocate 1.4 Megs
per CPU for the ring buffers if they are not used. Thus, on boot up
the ring buffers are set to a minimal size until something needs the
and they are expanded.

This works well for events and tracers (function, etc), but for the
asynchronous use of trace_printk() which can write to the ring buffer
at any time, does not expand the buffers.

On boot up a check is made to see if any trace_printk() is used to
see if the trace_printk() temp buffer pages should be allocated. This
same code can be used to expand the buffers as well.

Subject: [PATCH 0948/3298] tracing: Have tracing_sched_wakeup_trace() use
 standard unlock_commit

The functon tracing_sched_wakeup_trace() does an open coded unlock
commit and save stack. This is what the trace_nowake_buffer_unlock_commit()
is for.

Subject: [PATCH 0949/3298] tracing: Cache comms only after an event occurred

Whenever an event is registered, the comm of tasks are saved at
every task switch instead of saving them at every event. But if
an event isn't executed much, the comm cache will be filled up
by tasks that did not record the event and you lose out on the comms
that did.

Here's an example, if you enable the following events:

echo 1 > /debug/tracing/events/kvm/kvm_cr/enable
echo 1 > /debug/tracing/events/net/net_dev_xmit/enable

Note, there's no kvm running on this machine so the first event will
never be triggered, but because it is enabled, the storing of comms
will continue. If we now disable the network event:

echo 0 > /debug/tracing/events/net/net_dev_xmit/enable

and look at the trace:

cat /debug/tracing/trace
            sshd-2672  [001] ..s2   375.731616: net_dev_xmit: dev=eth0 skbaddr=ffff88005cbb6de0 len=242 rc=0

We see that process 2672 which triggered the events has the comm "sshd".
But if we run hackbench for a bit and look again:

cat /debug/tracing/trace
           <...>-2672  [001] ..s2   375.731616: net_dev_xmit: dev=eth0 skbaddr=ffff88005cbb6de0 len=242 rc=0

The stored "sshd" comm has been flushed out and we get a useless "<...>".

But by only storing comms after a trace event occurred, we can run
hackbench all day and still get the same output.

!CONFIG_TRACING both declares and defines (empty) trace_printk.
The first one is not redundant so it can be removed.

 attach_pci

Change the rtd520 driver to use the new `auto_attach()` method in
`struct comedi_driver` instead of the `attach_pci()` method.  I plan to
remove the `attach_pci()` and `attach_usb()` methods once nothing is
using them.

Tag the new `rtd520_auto_attach()` function definition with `__devinit`
as it is only called during PCI probe.

Subject: [PATCH 0957/3298] staging: ozwpan: use tasklet_kill in device
 remove/release process

Some driver uses tasklet_disable in device remove/release process,
tasklet_disable will inc tasklet->count and return. If the tasklet
is not handled yet under some softirq pressure, the tasklet will be
placed on the tasklet_vec, never have a chance to be excuted. This might
lead to a heavy loaded ksoftirqd, wakeup with pending_softirq, but
tasklet is disabled. tasklet_kill should be used in this case.

Subject: [PATCH 0970/3298] staging: comedi: hwdrv_apci3120: remove forward
 declarations

This source file is #include'd when building the addi_apci_3001 and
addi_apci_3120 drivers. All the functions in this file are actually
static and should not be exported to the kernel.

Move some of the functions to remove the need for the forward declarations
and make all of the functions in this file static. Note, this patch does
not try to fix any of the coding style issues in the functions.

Also, remove most of the big comment blocks preceding each function.
Leave the 'task' information for some of them to assist in later cleanup.

Subject: [PATCH 0977/3298] staging: comedi: APCI1710_82x54: remove forward
 declarations

This source file is #include'd when building the addi_apci_1710 driver.
All the functions in this file are actually static and should not be
exported to the kernel.

Move some of the functions to remove the need for the forward declarations
and make all of the functions in this file static. Note, this patch does
not try to fix any of the coding style issues in the functions.

Subject: [PATCH 0979/3298] staging: comedi: APCI1710_Chrono: remove forward
 declarations

This source file is #include'd when building the addi_apci_1710 driver.
All the functions in this file are actually static and should not be
exported to the kernel.

Move some of the functions to remove the need for the forward declarations
and make all of the functions in this file static. Note, this patch does
not try to fix any of the coding style issues in the functions.

Subject: [PATCH 0981/3298] staging: comedi: APCI1710_INCCPT: remove forward
 declarations

This source file is #include'd when building the addi_apci_1710 driver.
All the functions in this file are actually static and should not be
exported to the kernel.

Move some of the functions to remove the need for the forward declarations
and make all of the functions in this file static. Note, this patch does
not try to fix any of the coding style issues in the functions.

All the functions in this file are actually static and should not be
exported to the kernel.

Move some of the functions to remove the need for the forward declarations
and make all of the functions in this file static. Note, this patch does
not try to fix any of the coding style issues in the functions.

Subject: [PATCH 0985/3298] staging: comedi: hwdrv_apci3200: remove forward
 declarations

This source file is #include'd when building the addi_apci_3200 and
addi_apci_3300 driver. All the functions in this file are actually
static and should not be exported to the kernel.

Move some of the functions to remove the need for the forward declarations
and make all of the functions in this file static. Note, this patch does
not try to fix any of the coding style issues in the functions.

These defines were needed for the #ifdef'ery that used to exist
in addi_common.c. Since that has been removed these are no longer
used.

From 20a22b706b8ee37d1a2282f2c9bf7f2c73a5a7a5 Mon Sep 17 00:00:00 2001
From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Tue, 30 Oct 2012 18:06:33 -0700
Subject: [PATCH 0989/3298] staging: comedi: addi_apci_*: add
 module_comedi_pci_driver()

Pull the module init code out of addi_common.c and add it to
each addi-data driver. Rename the data and functions so they
have namespace associated with the drivers.

Subject: [PATCH 0992/3298] usb: phy: add R-Car USB phy driver

This patch adds Renesas R-Car USB phy driver.
It supports R8A7779 chip at this point.

R-Car has some USB controllers, but has only one phy-initializer.
So, this driver is counting users.

Subject: [PATCH 0993/3298] usb: musb: remove hand-crafted id handling

This replaced the handcrafted id handling by the PLATFORM_DEVID_AUTO
value which should do the same thing.

This patch probably also fixes ux500 because I did not find the "musbid"
variable to remove. And we close a tiny-unlikely race window becuase the
old code gave the id back before device was destroyed in the remove
case.

Subject: [PATCH 0994/3298] futex: Handle futex_pi OWNER_DIED take over
 correctly

Siddhesh analyzed a failure in the take over of pi futexes in case the
owner died and provided a workaround.
See: http://sourceware.org/bugzilla/show_bug.cgi?id=14076

The detailed problem analysis shows:

Futex F is initialized with PTHREAD_PRIO_INHERIT and
PTHREAD_MUTEX_ROBUST_NP attributes.

T1 lock_futex_pi(F);

T2 lock_futex_pi(F);
   --> T2 blocks on the futex and creates pi_state which is associated
       to T1.

T1 exits
   --> exit_robust_list() runs
       --> Futex F userspace value TID field is set to 0 and
           FUTEX_OWNER_DIED bit is set.

T3 lock_futex_pi(F);
   --> Succeeds due to the check for F's userspace TID field == 0
   --> Claims ownership of the futex and sets its own TID into the
       userspace TID field of futex F
   --> returns to user space

T1 --> exit_pi_state_list()
       --> Transfers pi_state to waiter T2 and wakes T2 via
       	   rt_mutex_unlock(&pi_state->mutex)

T2 --> acquires pi_state->mutex and gains real ownership of the
       pi_state
   --> Claims ownership of the futex and sets its own TID into the
       userspace TID field of futex F
   --> returns to user space

T3 --> observes inconsistent state

This problem is independent of UP/SMP, preemptible/non preemptible
kernels, or process shared vs. private. The only difference is that
certain configurations are more likely to expose it.

So as Siddhesh correctly analyzed the following check in
futex_lock_pi_atomic() is the culprit:

	if (unlikely(ownerdied || !(curval & FUTEX_TID_MASK))) {

We check the userspace value for a TID value of 0 and take over the
futex unconditionally if that's true.

AFAICT this check is there as it is correct for a different corner
case of futexes: the WAITERS bit became stale.

Now the proposed change

-	if (unlikely(ownerdied || !(curval & FUTEX_TID_MASK))) {
+       if (unlikely(ownerdied ||
+                       !(curval & (FUTEX_TID_MASK | FUTEX_WAITERS)))) {

solves the problem, but it's not obvious why and it wreckages the
"stale WAITERS bit" case.

What happens is, that due to the WAITERS bit being set (T2 is blocked
on that futex) it enforces T3 to go through lookup_pi_state(), which
in the above case returns an existing pi_state and therefor forces T3
to legitimately fight with T2 over the ownership of the pi_state (via
pi_state->mutex). Probelm solved!

Though that does not work for the "WAITERS bit is stale" problem
because if lookup_pi_state() does not find existing pi_state it
returns -ERSCH (due to TID == 0) which causes futex_lock_pi() to
return -ESRCH to user space because the OWNER_DIED bit is not set.

Now there is a different solution to that problem. Do not look at the
user space value at all and enforce a lookup of possibly available
pi_state. If pi_state can be found, then the new incoming locker T3
blocks on that pi_state and legitimately races with T2 to acquire the
rt_mutex and the pi_state and therefor the proper ownership of the
user space futex.

lookup_pi_state() has the correct order of checks. It first tries to
find a pi_state associated with the user space futex and only if that
fails it checks for futex TID value = 0. If no pi_state is available
nothing can create new state at that point because this happens with
the hash bucket lock held.

So the above scenario changes to:

T1 lock_futex_pi(F);

T2 lock_futex_pi(F);
   --> T2 blocks on the futex and creates pi_state which is associated
       to T1.

T1 exits
   --> exit_robust_list() runs
       --> Futex F userspace value TID field is set to 0 and
           FUTEX_OWNER_DIED bit is set.

T3 lock_futex_pi(F);
   --> Finds pi_state and blocks on pi_state->rt_mutex

T1 --> exit_pi_state_list()
       --> Transfers pi_state to waiter T2 and wakes it via
       	   rt_mutex_unlock(&pi_state->mutex)

T2 --> acquires pi_state->mutex and gains ownership of the pi_state
   --> Claims ownership of the futex and sets its own TID into the
       userspace TID field of futex F
   --> returns to user space

This covers all gazillion points on which T3 might come in between
T1's exit_robust_list() clearing the TID field and T2 fixing it up. It
also solves the "WAITERS bit stale" problem by forcing the take over.

Another benefit of changing the code this way is that it makes it less
dependent on untrusted user space values and therefor minimizes the
possible wreckage which might be inflicted.

As usual after staring for too long at the futex code my brain hurts
so much that I really want to ditch that whole optimization of
avoiding the syscall for the non contended case for PI futexes and rip
out the maze of corner case handling code. Unfortunately we can't as
user space relies on that existing behaviour, but at least thinking
about it helps me to preserve my mental sanity. Maybe we should
nevertheless :)

Subject: [PATCH 0995/3298] genirq: Provide means to retrigger parent

Attempts to retrigger nested threaded IRQs currently fail because they
have no primary handler. In order to support retrigger of nested
IRQs, the parent IRQ needs to be retriggered.

To fix, when an IRQ needs to be resent, if the interrupt has a parent
IRQ and runs in the context of the parent IRQ, then resend the parent.

Also, handle_nested_irq() needs to clear the replay flag like the
other handlers, otherwise check_irq_resend() will set it and it will
never be cleared.  Without clearing, it results in the first resend
working fine, but check_irq_resend() returning early on subsequent
resends because the replay flag is still set.

Problem discovered on ARM/OMAP platforms where a nested IRQ that's
also a wakeup IRQ happens late in suspend and needed to be retriggered
during the resume process.

Subject: [PATCH 0996/3298] irq: Set CPU affinity right on thread creation

As irq_thread_check_affinity is called ONLY inside the while loop in
the irq thread, the core affinity is set only when an interrupt
occurs. This patch sets the core affinity right after the irq thread
is created and before it waits for interrupts. In real-tiime targets
that do not typically change the core affinity of irqs during
run-time, this patch will save additional latency of an irq thread in
setting the core affinity during the first interrupt occurrence for
that irq.

Also, remove the parameter from v_pci_card_list_init() that caused
this information to be dumped.

Subject: [PATCH 1003/3298] staging: comedi: addi-data: remove io_addr array
 from card data

The io_addr array in the card data holds the PCI bar base addresses
returned by pci_resource_start(). Remove this array and just use
pci_resource_start() where needed in i_ADDI_Attach().

This also allows getting rid of i_pci_card_data() since it now
does nothing.

Subject: [PATCH 1004/3298] staging: comedi: addi-data: absorb pci_card_alloc()
 into i_ADDI_Attach()

The function pci_card_alloc() enables the pci device by calling
comedi_pci_enable() and then optionally calls pci_set_master() to
enable bus mastering for DMA.

Absorb this code directly into i_ADDI_Attach() as is more typical
for comedi PCI drivers. Also, remove the now unused i_Master
parameter from ptr_select_and_alloc_pci_card().

Subject: [PATCH 1007/3298] staging: comedi: addi-data: remove attach option to
 disable dma

This pci driver currently uses the comedi legacy attach mechanism
which allows the user to pass configuration options to the driver
when it is attached to the comedi subsystem. The use of these
configuration options is preventing the conversion of the addi-data
drivers to the comedi auto attach mechanism.

For the addi-data drivers, option[2] is used to enable/disable dma.
The default (0) action is to enable dma is the driver supports it.

Remove this configuration option and just enable dma if it is
supported.

Subject: [PATCH 1009/3298] staging: comedi: addi-data: use attach_pci callback

Use the comedi pci auto config mechanism to attach the addi-data
drivers. This allows removing all the PCI bus walking code.

Add a function, addi_find_boardinfo(), to find the driver specific
boardinfo. Since this function is currently in the common code we
have to use the pointer to the boardinfo that is stored in the
comedi_driver pointer.

Subject: [PATCH 1011/3298] staging: comedi: addi-data: remove 'allocated' from
 the private data

This variable is only used as a flag to indicate that the pci device
has been enabled. Use the comedi_device 'iobase' variable to indicate
this instead. This is how it's normally handled in the comedi pci
drivers.

Make the call to comedi_pci_disabled() in i_ADDI_Detach() common
and move it to the end of the function. Both the if and else case
require it.

This variable is only used in the detach of the addi-data boards to
indicate that the attach of the board was successful and that the reset
function can be called. We can use the dev->iobase variable to indicate
this instead. Once this variable is set the attach always completes.

Subject: [PATCH 1013/3298] staging: comedi: addi-data: remove
 addi_amcc_s5933.h

Now that the PCI bus walking has been removed from the addi-data
drivers, the only differenced between addi_amcc_s9533.h and the
standard comedi amcc_s5933.h is the additional defines for the
apci3120 "ADDON RELATED ADDITIONS". Move those defines to
hwdrv_apci3120.c.

Modify all the addi-data drivers to then include the standard
comedi amcc_s5933.h header and delete the duplicate in addi-data.

Subject: [PATCH 1029/3298] staging: comedi: skel: do auto-attachment of PCI
 devices

This driver is an example of how to write a Comedi driver and includes
some code for handling PCI devices, but not very much.  It calls
`comedi_pci_auto_config()` at PCI probe time.  That normally expects to
call the comedi driver's `auto_attach()` hook (or the deprecated
`attach_pci()` hook), but will fall back to using the `attach()` hook
that should only be used for attaching devices "manually" via the
`COMEDI_DEVCONFIG` ioctl.

Add an `auto_attach()` hook (`skel_auto_attach()`) to handle
auto-attachment of supported PCI devices.  Add comments to the
`attach()` hook (`skel_attach()`) to indicate that it shouldn't
generally allow PCI devices to be attached that way (and probably isn't
needed at all for PCI-only Comedi drivers).  Add code to the `detach()`
hook (`skel_detach()`) to disable PCI devices enabled by the
`auto_attach()` hook.

`skel_auto_attach()` calls new function `skel_find_pci_board()` to find
a matching element in `skel_boards[]`.  PCI device ID information has
been added to `skel_boards[]` to give the function something to look
for.

Remove the `pci_dev` member of `struct skel_private` as drivers now use
the `hw_dev` member of `struct comedi_device` to get at the PCI device.

add the check and fail if it returns other than 0.

Subject: [PATCH 1039/3298] serial:ifx6x60:Prevent data transfer when IFX6x60
 port is shutdown

This patch is to implement following 2 places to avoid potential error when IFX6x60 port shutdown:
1) Clear Flag IFX_SPI_STATE_IO_AVAILABLE to disable data transfer when Modem port is shutdown;
2) Clear Flag IFX_SPI_STATE_IO_IN_PROGRESS and IFX_SPI_STATE_IO_READY when reopen port.
This is because last port shutdown may happen when SPI/DMA transfer is in progress, if the last
data transfer is not completed(for example due to modem reset), the Flag IFX_SPI_STATE_IO_IN_PROGRESS
will be set forever, so when IFX port is activated again, IFX_SPI_STATE_IO_IN_PROGRESS will prevent
transferring data forever. And if don't clear IFX_SPI_STATE_IO_READY, it may cause one more SPI frame
transferring in spit there is not data need to be transfer.

Subject: [PATCH 1041/3298] USB: EHCI: prepare to make ehci-hcd a library
 module

This patch (as1624) prepares ehci-hcd for being split up into a core
library and separate platform driver modules.  A generic
ehci_hc_driver structure is created, containing all the "standard"
values, and a new mechanism is added whereby a driver module can
specify a set of overrides to those values.  In addition the
ehci_setup(), ehci_suspend(), and ehci_resume() routines need to be
EXPORTed for use by the drivers.

As a side effect of this change, a few routines no longer need to be
marked __maybe_unused.

Subject: [PATCH 1042/3298] USB: EHCI: make ehci-pci a separate driver

This patch (as1625) splits the PCI portion of ehci-hcd out into its
own separate driver module, called ehci-pci.  Consistently with the
current practice, the decision whether to build this module is not
user-configurable.  If EHCI and PCI are enabled then the module will
be built, always.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes a term's translation in Documentation/zh_CN/arm64/memory.txt
The modification is based on Catalin Marinas <catalin.marinas@arm.com>'s
suggestion:
    "memory" in "ffffffc000000000 ffffffffffffffff 256GB memory"
    should  be treated as "kernel logical memory map",
    so the translation should be "内核逻辑内存映射".

Subject: [PATCH 1046/3298] mei: normalize timeouts definitions

1. The hardware book defines timeouts in seconds
 so we stick to this and define the wrapper function
 mei_secs_to_jiffies  around  msecs_to_jiffies
 to use be used instead multiplying by HZ

2. We add name space prefix MEI_ to all timer defines

For sake of amthif consolidation move amthif specific code from
mei_write to mei_amthif_write

The original mei_amthif_write to mei_amthif_send_cmd
as this function deals with sending single command
while mei_amthif_write is interface function called from
the main driver which in turns calls mei_amthif_send_cmd

Subject: [PATCH 1051/3298] staging: comedi: gsc_hpdi: use auto_attach method

This driver does not need to support manual attachment of supported PCI
devices.  Replace the `attach()` hook (`hpdi_attach()`) with an
`auto_attach()` hook (`hpdi_auto_attach()`).  This will be called via
`comedi_pci_auto_config()` at PCI probe time.

This driver no longer increments the PCI reference during attachment, so
remove the call to `pci_dev_put()` when detaching the device.

Subject: [PATCH 1052/3298] staging: comedi: gsc_hpdi: remove devpriv->hw_dev

The `hw_dev` member of `struct hpdi_private` is used to point to the
`struct pci_dev`.  This is redundant as the `struct comedi_device`
already has a pointer to the `struct device` within the `struct pci_dev`
and there is a convenient inline function, `comedi_to_pci_dev(dev)` that
returns a pointer to the `struct pci_dev`.

Remove the redundant `hw_dev` member and use alternate ways to get at
the `struct pci_dev`.

Subject: [PATCH 1053/3298] staging: comedi: gsc_hpdi: don't store physical
 base addresses

In `struct hpdi_private`, the `plx9080_phys_iobase` and
`hpdi_phys_iobase` hold the physical memory addresses from the PCI
BARs used by this driver.  The physical addresses are only really needed
when ioremapping the resources when the device is being attached by
`hpdi_auto_attach()`.  A non-zero value of the `hpdi_phys_iobase` is
also used to indicate that a call to `comedi_pci_enable()` was
successful so that `comedi_pci_disable()` should be called when the
device is detached by `hpdi_detach()`.

Remove the `plx9080_phys_iobase` and `hpdi_phys_iobase` members and use
`dev->iobase` as a flag to indicate whether `comedi_pci_disable()` needs
to be called by `hpdi_detach()`.

Subject: [PATCH 1054/3298] staging: comedi: gsc_hpdi: remove board(dev)
 function

The `board(dev)` function just casts `dev->board_ptr` to a pointer to
the private data type `struct hpdi_private` and returns it.  It's only
called from one function: `hpdi_auto_attach()`.

Remove `board()` and use a local variable to point to the `struct
hpdi_private` data structure.

Subject: [PATCH 1059/3298] staging: comedi: addi_apci_1710: separate from
 addi_common.c

This addi-data driver uses a private function to initialize all
the subdevices during the attach of the board.

Copy the code in addi_common.c to this driver and remove the #include
that caused addi_common.c to be compiled with this driver. This will
allow removing the special handling for the apci1710 board in the
common code.

Rename the attach_pci and detach functions so they have namespace
associated with this driver.

Subject: [PATCH 1060/3298] staging: comedi: addi-data: remove special handling
 for apci1710

Now that the addi_apci_1710 driver is not using addi_common.c we can
remove the CONFIG_APCI_1710 define and all the special handling for
the initialization of it's subdevices.

Also remove the i_ADDIDATA_InsnReadEeprom() function from the
addi_apci_1710 driver. This board does not have an eeprom subdevice
and does not use this function.

Subject: [PATCH 1061/3298] staging: comedi: addi_apci_1710: cleanup
 addi_find_boardinfo()

This driver uses the comedi PCI auto attach mechanism and the comedi
core does not use the boardinfo during the attach.

Now that this driver has the attach separated from addi_common.c we
can remove passing the boardinfo in the comedi_driver and cleanup
the code that finds the boardinfo.

Also, rename addi_find_boardinfo() so it has namespace associated
with this driver.

Subject: [PATCH 1062/3298] staging: comedi: addi_apci_1710: remove
 i_ADDI_Reset

This driver is now separate from the "common" code used with the
addi-data drivers. There is no need to use i_ADDI_Reset() to call
the correct "reset" function.

Remove the i_ADDI_Reset() function and the 'reset' pointer to the
real function from the boardinfo and just call the function directly
where needed.

has a localized attach we already know the use of the bars so
this information in the boardinfo is unnecessary.

Subject: [PATCH 1069/3298] staging: comedi: jr3_pci: use auto_attach method

This driver does not need to support manual attachment of supported PCI
devices.  Replace the `attach()` hook (`jr3_pci_attach()`) with an
`auto_attach()` hook (`jr3_pci_auto_attach()`).  This will be called via
`comedi_pci_auto_config()` at PCI probe time.

This driver no longer increments the PCI reference count during
attachment, so remove the call to `pci_dev_put()` when detaching the
device.

The `pci_dev` member of `struct jr3_pci_dev_private` is used to point to
the `struct pci_dev`.  This is redundant as the `struct comedi_device`
already has a pointer to the `struct device` within the `struct pci_dev`
and there is a convenient inline function, `comedi_to_pci_dev(dev)` that
returns a pointer to the `struct pci_dev`.

Remove the redundant `pci_dev` member and use alternate ways to get at
the `struct pci_dev`.

 devpriv->pci_enabled

The `pci_enabled` member of `struct jr3_pci_dev_private` is used to
indicate whether the call to `comedi_pci_enable()` was successful.  The
'detach' routine `jr3_pci_detach()` uses this to decide whether to call
`comedi_pci_disable()`.  The `iobase` member of `struct comedi_device`
is not used by this driver so it can be used for the same purpose.

Remove the `pci_enabled` member and use the spare `dev->iobase` instead.

Subject: [PATCH 1074/3298] staging: comedi: jr3_pci: update driver description
 comment

Reformat the comment used to describe the Comedi driver to use the usual
block comment style.

Update the information reflecting the fact that the driver no longer
supports manual attachment of devices via the `COMEDI_DEVCONFIG` ioctl
and `attach()` method.

Also, in the instructions indicating where to put the firmware file,
mention the expected name of the file since the driver requests the
firmware file by name.

-
-  Configuration options:
-  [0] - PCI bus number - if bus number and slot number are 0,
-                         then driver search for first unused card
-  [1] - PCI slot number

Subject: [PATCH 1077/3298] perf tests: Add attr tests under builtin test
 command

The test attr suite is run only if it's run under perf source directory,
or tests are found in installed path.

Otherwise tests are omitted (notification is displayed) and finished as
successful.

Subject: [PATCH 1089/3298] iio: Reject trailing garbage when parsing fixed
 point numbers

When parsing a fixed point number IIO stops parsing the string once it has
reached the last requested decimal place. This means that the remainder of the
string is silently accepted regardless, of whether it is part of a valid number
or not. This patch modifies the code to scan the whole string and only accept
valid numbers. Since fract_mult is 0 after the last decimal place any digit that
may follows won't affect the result.

Subject: [PATCH 1092/3298] x86: apic: Use tsc deadline for oneshot when
 available

If the TSC deadline mode is supported, LAPIC timer one-shot mode can be
implemented using IA32_TSC_DEADLINE MSR. An interrupt will be generated
when the TSC value equals or exceeds the value in the IA32_TSC_DEADLINE
MSR.

This enables us to skip the APIC calibration during boot. Also, in
xapic mode, this enables us to skip the uncached apic access to re-arm
the APIC timer.

As this timer ticks at the high frequency TSC rate, we use the
TSC_DIVISOR (32) to work with the 32-bit restrictions in the
clockevent API's to avoid 64-bit divides etc (frequency is u32 and
"unsigned long" in the set_next_event(), max_delta limits the next
event to 32-bit for 32-bit kernel).

Subject: [PATCH 1093/3298] PM / QoS: Document request manipulation requirement
 for flags

In fact, the callers of dev_pm_qos_add_request(),
dev_pm_qos_update_request() and dev_pm_qos_remove_request() for
requests of type DEV_PM_QOS_FLAGS need to ensure that the target
device is not RPM_SUSPENDED before using any of these functions (or
be prepared for the new PM QoS flags to take effect after the device
has been resumed).  Document this in their kerneldoc comments.

Because the "tsc" clock isn't in nanoseconds, the ring buffer must be
reset when changing clocks so that incomparable timestamps don't end up
in the same trace.

Tested: Confirmed switching clocks resets the trace buffer.

Subject: [PATCH 1098/3298] tracing: Separate open function from set_event and
 available_events

The open function used by available_events is the same as set_event even
though it uses different seq functions. This causes a side effect of
writing into available_events clearing all events, even though
available_events is suppose to be read only.

There's no reason to keep a single function for just the open and have
both use different functions for everything else. It is a little
confusing and causes strange behavior. Just have each have their own
function.

Subject: [PATCH 1099/3298] tracing: Remove unused function unregister_tracer()

The function register_tracer() is only used by kernel core code,
that never needs to remove the tracer. As trace_events have become
the main way to add new tracing to the kernel, the need to
unregister a tracer has diminished. Remove the unused function
unregister_tracer(). If a need arises where we need it, then we
can always add it back.

Subject: [PATCH 1100/3298] tracing: Make tracing_enabled be equal to
 tracing_on

The tracing_enabled file has been deprecated as it never was able
to serve its purpose well. The tracing_on file has taken over.
Instead of having code to keep tracing_enabled, have the tracing_enabled
file just set tracing_on, and remove the tracing_enabled variable.

This allows us to remove the tracing_enabled file. The reason that
the remove is in a different change set and not removed here is
in case we find some lonely userspace tool that requires the file
to exist. Then the removal patch will get reverted, but this one
will not.

Subject: [PATCH 1101/3298] tracing: Remove deprecated tracing_enabled file

The tracing_enabled file was used as a quick way to stop
tracers, and try to bring down overhead for things like
the latency tracers (irqsoff, wakeup, etc). But it didn't
work that well.

The tracing_on file was created as a really fast way to
stop recording into the ftrace ring buffer and can interact
with the kernel. That is a tracing_off() call in the kernel
can disable recording of events, and then from userspace one
could echo 1 into the tracing_on file to continue it. The
tracing_enabled function did too much to allow for this.

The tracing_on has taken over as a way to start and stop tracing
and the tracing_enabled file should not be used. But because of
its existance, it still confuses people. Over a year ago the
following commit was added:

 commit 6752ab4a9c30d5411b2dfdb251a3f1cb18aae487
 Author: Steven Rostedt <srostedt@redhat.com>
 Date:   Tue Feb 8 13:54:06 2011 -0500

    tracing: Deprecate tracing_enabled for tracing_on

This commit added a WARN_ON() if the tracing_enabled file's variable
was changed. After this was added, only LatencyTop complained, and
they soon fixed their tool as there was no reason that LatencyTop
should touch this file as it was using the perf ring buffers which
this file does not interact with. But since that time no one else
has complained about this WARN_ON(). Thus it is safe to assume that
this file is no longer needed. Time to get rid of it.

Subject: [PATCH 1102/3298] tracing: Use irq_work for wake ups and remove
 *_nowake_*() functions

Have the ring buffer commit function use the irq_work infrastructure to
wake up any waiters waiting on the ring buffer for new data. The irq_work
was created for such a purpose, where doing the actual wake up at the
time of adding data is too dangerous, as an event or function trace may
be in the midst of the work queue locks and cause deadlocks. The irq_work
will either delay the action to the next timer interrupt, or trigger an IPI
to itself forcing an interrupt to do the work (in a safe location).

With irq_work, all ring buffer commits can safely do wakeups, removing
the need for the ring buffer commit "nowake" variants, which were used
by events and function tracing. All commits can now safely use the
normal commit, and the "nowake" variants can be removed.

Add trace_options to the kernel command line parameter to be able to
set options at early boot. For example, to enable stack dumps of
events, add the following:

  trace_options=stacktrace

This along with the trace_event option, you can get not only
traces of the events but also the stack dumps with them.

Subject: [PATCH 1104/3298] ASoC: mxs-saif: Fix channel swap for 24-bit format

Playing 24-bit format file leads to channel swap on mx28 and the reason is that
the current driver performs one write/read to/from the SAIF_DATA register to
trigger the transfer.

This approach works fine for S16_LE case because SAIF_DATA is a 32-bit register
and thus is capable of storing the 16-bit left and right channels, but for the
S24_LE case it can only store one channel, so in order to not lose the FIFO sync
an extra read/write is needed.

Subject: [PATCH 1105/3298] x86: Don't clobber top of pt_regs in nested NMI

The nested NMI modifies the place (instruction, flags and stack)
that the first NMI will iret to.  However, the copy of registers
modified is exactly the one that is the part of pt_regs in
the first NMI.  This can change the behaviour of the first NMI.

In particular, Google's arch_trigger_all_cpu_backtrace handler
also prints regions of memory surrounding addresses appearing in
registers.  This results in handled exceptions, after which nested NMIs
start coming in.  These nested NMIs change the value of registers
in pt_regs.  This can cause the original NMI handler to produce
incorrect output.

We solve this problem by interchanging the position of the preserved
copy of the iret registers ("saved") and the copy subject to being
trampled by nested NMI ("copied").

This patch (as1628) fixes a build error in the ehci-platform driver
when compiled for the PowerPC architecture.  The error was introduced
by commit 99f91934a907df31ba878dfdd090002049dc476a (USB: EHCI: make
ehci-platform a separate driver).

The fix is simple; a few additional header-file #includes are needed.

Subject: [PATCH 1107/3298] USB: ohci-exynos: initialize registers pointer
 earlier

In the former code, we have a race condition between the first interrupt
and the regs field initilization in the usb_hcd structure.
If the OHCI irq fires before hcd->regs is set, we are getting a null
pointer dereference in ohci_irq.

When calling usb_add_hcd(), it first executes the reset() callback,
then enables the ohci interrupt, and finally executes the start()
callback. So moving the ohci_init() call which actually initializes the
reg field from start() to reset() should remove the race.

Tested by enabling the external HSIC hub in the bootloader on an exynos5
machine and booting. With the former code, this triggers an early interrupt
about 50% of the boots and a subsequent kernel panic in ohci_irq when trying
to access the registers.

Subject: [PATCH 1108/3298] USB: EHCI: fix build error by making ChipIdea host
 a normal EHCI driver

This patch (as1627) splits the ehci-hcd core code, which has become a
separate library module, out from the ChipIdea host driver.  Instead
of #include-ing ehci-hcd.c directly, the ChipIdea module will now use
the ehci-hcd library in a normal fashion.

This fixes a build error caused by commit
3e0232039967d7a1a06c013d097458b4d5892af1 (USB: EHCI: prepare to make
ehci-hcd a library module); I had forgotten about the unorthodox way
the ChipIdea driver uses the ehci-hcd code.

Subject: [PATCH 1110/3298] staging: comedi: addi_apci_3120: merge in
 addi_apci_3001 driver

The addi_apci_3120 and addi_apci_3001 drivers share the same low-level
board support code (hwdrv_apci3120). Merge the boardinfo and PCI_DEVICE
information from the addi_apci_3001 driver into the addi_apci_3120
driver and delete then delete the addi_apci_3001 driver.

Now that the apci3001 and apci3120 boards are merged we can remove
this unnecessary define.

Subject: [PATCH 1112/3298] staging: comedi: addi_apci_3120: separate from
 addi_common.c

The addi_apci_3120 driver is the only addi-data driver that supports
dma.

Copy the code in addi_common.c to this driver and remove the #include
that caused addi_common.c to be compiled with this driver. This will
allow removing the special handling for allocating and freeing the
dma buffers in the common code.

Rename the attach_pci and detach functions so they have namespace
associated with this driver.

Subject: [PATCH 1113/3298] staging: comedi: addi_common: remove dma setup/free
 code

None of the addi-data drivers that use the "common" code in addi_common.c
support dma. Remove the code that sets up the dma and allocates the buffers
in the attach and the code that frees the buffers in the detach.

 i_ADDI_Reset()

This driver is now separate from the "common" code used with the
addi-data drivers. There is no need to use i_ADDI_Reset() to call
the correct "reset" function.

Remove the i_ADDI_Reset() function and the 'reset' pointer to the
real function from the boardinfo and just call the function directly
where needed.

The addi-data "common" code always allocates 7 subdevices. This
driver is now separate from that code so we can remove the unused
subdevices.

Subject: [PATCH 1128/3298] staging: comedi: addi_apci_3120: remove the
 'i_IorangeBase*'

These values in the boardinfor were used in the common addi-data
attach code to work out use of the PCI bars. Since this driver
has a localized attach we already know the use of the bars so
this information in the boardinfo is unnecessary.

 subdevice init

Only the apci3120 board supports an analog output subdevice. The
boardinfo indicates this by setting the 'i_NbrAoChannel' value.

The range table as well as the function used for the insn_write
operation are fixed for the analog outputs. Remove this information
from the boardinfo and use it directly in the subdevice init.

 addi_find_boardinfo()

This driver uses the comedi PCI auto attach mechanism and the comedi
core does not use the boardinfo during the attach.

Now that this driver has the attach separated from addi_common.c we
can remove passing the boardinfo in the comedi_driver and cleanup
the code that finds the boardinfo.

Also, rename addi_find_boardinfo() so it has namespace associated
with this driver.

Subject: [PATCH 1137/3298] staging: et131x: Remove unused buffer[1,2]
 variables.

The fbr_lookup struct variables buffer1 and buffer2 are only assigned
and never used, so remove them.

Subject: [PATCH 1138/3298] staging: et131x: Align ring_index and fbr[]
 indicies

A ring_index value of 0 is being used to reference the free buffer ring
fbr[1] and ring_index=1 is used to reference fbr[0]. Avoid this
confusing referencing by swapping the indicies so that ring_index=0
refers to fbr[0] and vice versa.

From: Kevin McKinney <klmckinney1@gmail.com>
Date: Thu, 1 Nov 2012 23:42:22 -0400
Subject: [PATCH 1150/3298] Staging: bcm: Remove typedef for _USB_RCB and call
 directly.

This patch removes typedef for
_USB_RCB, changes the name of the
struct to bcm_usb_rcb. In addition,
any calls to typedefs USB_RCB, or
*PUSB_RCB are changed to call the
struct directly.

Subject: [PATCH 1158/3298] staging: comedi: adl_pci9118: split
 pci9118_attach()

Split most of the functionality of the attach routine `pci9118_attach()`
into a new function `pci9118_common_attach()` that can be called when
auto-attachment of devices is supported.  Move the enabling of the PCI
device and its i/o regions into this function.  Do the requesting of the
interrupt near the end of the function so it doesn't get enabled before
the device is ready.

Note that auto-attachment of PCI devices is currently broken in this
driver because the list of board names referred to by the `struct
comedi_driver` does not contain a "wildcard" entry matching the comedi
driver name.  This won't be a problem once support for the
`auto_attach()` method is added.

Don't bother recording the PCI vendor ID of each board in `boardtypes[]`
as they are all the same and the code doesn't use it anyway.

Subject: [PATCH 1160/3298] staging: comedi: adl_pci9118: support
 auto-attachment

Support auto-attachment of supported PCI devices by adding the
`auto_attach()` hook (`pci9118_auto_attach()`) to the `struct
comedi_driver`.  This is called via `comedi_pci_auto_attach()` at PCI
probe time.

Previously, the driver's call to `comedi_pci_auto_config()` would fall
back to the old method of auto-attaching devices and would fail because
it couldn't find a board name matching the driver name.  The new method
doesn't care about that.

There are still a few problems.  All the boards supported by this driver
have the same PCI vendor and device ID, so it will just pick the first
supported board type, "pci9118dg".  (Other supported board types have
different AI ranges or different AI speeds, but are otherwise the same.)
Also, manual attachment of devices allows several optional features to
be configured, such as use of an external multiplexord, specified
sample&hold delays and options to ignore certain hardware errors.  These
will all be set to defaults for auto-attached devices.  A future version
of the driver may address these issues via configurable device
attributes.

Subject: [PATCH 1161/3298] x86: hpet: Fix masking of MSI interrupts

HPET_TN_FSB is not a proper mask bit; it merely toggles between MSI and
legacy interrupt delivery. The proper mask bit is HPET_TN_ENABLE, so
use both bits when (un)masking the interrupt.

Subject: [PATCH 1164/3298] uprobes/powerpc: Do not use arch_uprobe_*_step()
 helpers

No functional changes.

powerpc is the only user of arch_uprobe_enable/disable_step() helpers,
but they should die. They can not be used correctly, every arch needs
its own implementation (like x86 does). And they do not really help
even as initial-and-almost-working code, arch_uprobe_*_xol() hooks can
easily use user_enable/disable_single_step() directly.

Change arch_uprobe_*_step() to do nothing, and convert powerpc to use
ptrace helpers. This is equally wrong, powerpc needs the arch-specific
fixes.

This patch (as1629) fixes a build error in the ChipIdea host driver
when compiled for the ARM architecture.  The error was introduced
by commit 99f91934a907df31ba878dfdd090002049dc476a (USB: EHCI: make
ehci-platform a separate driver).

The fix is simple; an additional header-file #include is needed.

Subject: [PATCH 1168/3298] staging:iio:adis16400: Fix adis16334 sampling
 frequency control

Setting the sampling frequency for the adis16334 differs from the other devices.
This patch introduces two new callback functions to the adis16400 chip_info
struct which are used to specify how to read and write the current sample rate.
The patch also introduces the proper implementations for these callbacks for the
adis16334.

Related to this is that the adis16334 has no slow mode and so we do not limit
the SPI clock rate to 300kHz during initialization. The patch adds a new flag
for devices which do have a slow mode.

Subject: [PATCH 1169/3298] staging:iio:adis16400: Fix product id check

The product id check currently ANDs the read id with 0xF000 and compares the
result to the product id from the chip info. Since none of the product ids in
the chip info table end in 0x000 the check will always fail. Furthermore it is
also wrong, the product id in the PROD_ID register will always match the part
number of the device.

Some of the ADIS16XXX devices are identical from a software point of
view with the product id register having a different content. If we keep the
current scheme of storing the product id in the chip info table this would
require us to have multiple almost identical chip info table entries. So instead
this patch changes the code to parse the product id from the device name.

Subject: [PATCH 1170/3298] staging:iio:adis16400: Remove now duplicated
 chip_table entry

The ADIS1360 and ADIS13605 are very similar and do have the same software
interface. The only difference is the contents of the PROD_ID register. Since we
now read the product id from the device name instead of the chip_info struct we
can use the same chip_table entry for both the ADIS1360 and ADIS13605.

These are accessed without a lock when ending STA PSM. If the
sta_cleanup timer accesses these lists at the same time, we might crash.

This may fix some mysterious crashes we had during
ieee80211_sta_ps_deliver_wakeup.

+The struct perf_event_attr test (attr tests) support
+====================================================
+This testing support is embedded into perf directly and is governed
+by the PERF_TEST_ATTR environment variable and hook inside the
+sys_perf_event_open function.
+
+The general idea is to store 'struct perf_event_attr' details for
+each event created within single perf command. Each event details
+are stored into separate text file. Once perf command is finished
+these files are checked for values we expect for command.
+
+The attr tests consist of following parts:
+
+tests/attr.c
+------------
+This is the sys_perf_event_open hook implementation. The hook
+is triggered when the PERF_TEST_ATTR environment variable is
+defined. It must contain name of existing directory with access
+and write permissions.
+
+For each sys_perf_event_open call event details are stored in
+separate file. Besides 'struct perf_event_attr' values we also
+store 'fd' and 'group_fd' values to allow checking for groups.
+
+tests/attr.py
+-------------
+This is the python script that does all the hard work. It reads
+the test definition, executes it and checks results.
+
+tests/attr/
+-----------
+Directory containing all attr test definitions.
+Following tests are defined (with perf commands):
+
+  perf record kill                              (test-record-basic)
+  perf record -b kill                           (test-record-branch-any)

Subject: [PATCH 1189/3298] perf tools: Use normalized arch name for searching
 objdump path

David reported that perf report for i686 target data on x86_64 host
failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need
to do it at all.  To prevent similar artifacts, normalize arch name when
comparing host and file architectures.

Subject: [PATCH 1190/3298] perf tools: Introduce struct hist_browser_timer

Currently various hist browser functions receive 3 arguments for
refreshing histogram but only used from a few places.  Also it's only
for perf top command so that it can be NULL for other (and probably
most) cases.  Pack them into a struct in order to reduce number of those
unused arguments.

This is a mechanical change and does not intend a functional change.

Date: Fri, 2 Nov 2012 14:50:06 +0900
Subject: [PATCH 1191/3298] perf report: Postpone objdump check until
 annotation requested

David reported that current perf report refused to run on a data file
captured from a different machine because of objdump.

Since the objdump tools won't be used unless annotation was requested,
checking its presence at init time doesn't make sense.

Subject: [PATCH 1194/3298] perf tests: Fix attr watermark field name typo

Currently the 'watermark' field is coded as 'watermask'.

As the type is global through the framework and tests, the typo spawned
no error.

Since we allow multiple values in event field assignment, there's no
need for 'optional' field.. old version removal leftover.

Adding some comments into attr.py script regarding the test event load.

We know that the sample buffer will at most need to hold two 16 bit samples and
the 64 bit aligned 64 bit timestamp. Preallocate a buffer large enough to hold
this instead of allocating and freeing it each time a sample is read.

Subject: [PATCH 1197/3298] staging:iio:ad7887: Rework regulator handling

Rework the regulator handling of the ad7887 driver to match more closely what we
do for other drivers. Only request the regulator if a external reference is
used, but treat it as an error if requesting the regulator fails. Also remove
the possibility to specify the reference voltage via platform data and always
use the regulator for this.

Subject: [PATCH 1198/3298] staging:iio:ad7887: Squash everything into one file

The recent cleanups have decimated the drivers code size by quite a bit. It is
only a few hundred lines in total now and we also always build buffer support,
so there really is no need to spread the driver out over multiple files. Putting
everything into one file also allows to reduce the code size a bit more by
removing a few lines of boilerplate code.

While it is not recommended to use the internal reference in two channel mode in
order to obtain optimal performance it is still possible to use it.

While we are at it also get rid of the duplicate tx_cmd_buf entries. There are
only two unique entries. One for channel 1 and one for channel 2.

Use the passed in chan spec in ad7887_read_raw instead of alawys using the first
chan spec entry from the chip info data. Since all channels have the same shift
and realbits from a functional point of view it does not matter which chan spec
is used, but the patch makes the a bit more clear.

Subject: [PATCH 1204/3298] staging: comedi: cb_pcidas64: use auto_attach
 method

This driver does not need to support manual attachment of supported PCI
devices.  Replace the `attach()` hook with an `auto_attach()` hook.
This will be called via `comedi_pci_auto_config()` at PCI probe time.

The `auto_attach()` calls new function `cb_pcidas64_find_pci_board()` to
find the correct entry in `pcidas64_boards[]` for the PCI device.

This driver no longer increments the PCI reference count during
attachment, so remove the call to `pci_dev_put()` when detaching the
device.

Subject: [PATCH 1205/3298] staging: comedi: cb_pcidas64: fix printks

Replace `printk` calls with something else.  For the `DEBUG_PRINT()`
macro, use `pr_debug()` (if `PCIDAS64_DEBUG macro defined) or
`no_printk()`.

Fix a few `DEBUG_PRINT()` calls due to compiler warnings and add
newlines where they are missing.

Subject: [PATCH 1207/3298] staging: comedi: comedidev.h: make comedi_board()
 parameter const

The inline function `comedi_board(dev)` merely returns `dev->board_ptr`.
It does not modify any members of `*dev` so make its parameter a const
pointer.

Subject: [PATCH 1208/3298] staging: comedi: cb_pcidas64: remove board(dev)
 inline

The `board(dev)` inline function returns `dev->board_ptr` cast from
`const void *` to `struct pcidas64_board *`.  It really ought to return
a `const struct pcidas64_board *`.  Rather than fix the function, just
remove it and replace the calls with a local variable `thisboard` in the
functions that call it.  `thisboard` is set to the result of the common
inline function `comedi_board(dev)` defined in "comedidev.h".

Fix a little resulting fall-out from the inline function
`ai_dma_ring_count(board)` whose parameter should have been a const
pointer.

Subject: [PATCH 1209/3298] staging: comedi: cb_pcidas64: fix forward
 declarations 1

Move `setup_subdevices()` and remove a load of forward declarations.
Added a forward declaration of `setup_subdevices()` temporarily.

Subject: [PATCH 1211/3298] staging: comedi: cb_pcidas64: fix forward
 declarations 3

Move `abort_dma()`, `disable_ai_pacing()`, `i2c_high_udelay`,
`i2c_low_udelay`, `i2c_set_sda()`, `i2c_set_scl()`, `i2c_write_byte()`,
`i2c_read_ack()`, `i2c_start()`, `i2c_stop()`, `i2c_write()`,
`get_divisor()`, `check_adc_timing()`, `disable_ai_pacing()`,
`abort_dma()`, `get_ao_divisor()`, `ao_inttrig()`,
`caldac_8800_write()`, `caldac_i2c_write()`, `check_adc_timing()`,
`get_divisor()`, and `get_ao_divisor()`, and remove their forward
declarations.

From: Ian Abbott <abbotti@mev.co.uk>
Date: Fri, 2 Nov 2012 19:18:05 +0000
Subject: [PATCH 1212/3298] staging: comedi: cb_pcidas64: fix forward
 declararions 4

Move `disable_plx_interrupts()`, `disable_ai_interrupts()`,
`enable_ai_interrupts()`, `set_ai_fifo_segment_length()`,
`set_ai_fifo_size()`, `ai_fifo_size()`, `load_ao_dma_buffer()`, and
`load_ao_dma()`, and remove forward declarations of these functions.

Subject: [PATCH 1213/3298] staging: comedi: cb_pcidas64: update driver comment

Update the comedi driver comment to reflect the fact that manual
attachment of devices is no longer supported.  Also replace the request
to file a bug report about unidentified PCI device IDs with a request to
let the maintainers know about such devices.

Reformat the comment using the usual block comment style.

Subject: [PATCH 1214/3298] staging: comedi: addi_apci_1032: separate from
 addi_common.c

The addi_apci_1032 driver is a simple digital input board with 32
optically isolated inputs. Using the addi-data "common" code introduces
a lot of bloat.

Copy the code in addi_common.c to this driver and remove the #include
that caused addi_common.c to be compiled with this driver. This will
allow removing the special handling for allocating and freeing the
dma buffers in the common code.

Rename the attach_pci and detach functions so they have namespace
associated with this driver.

Subject: [PATCH 1215/3298] staging: comedi: addi_apci_1032: remove
 i_ADDI_Reset()

This driver is now separate from the "common" code used with the
addi-data drivers. There is no need to use i_ADDI_Reset() to call
the correct "reset" function.

Remove the i_ADDI_Reset() function and the 'reset' pointer to the
real function from the boardinfo and just call the function directly
where needed.

Subject: [PATCH 1221/3298] staging: comedi: addi_apci_1032: board has 32
 digital inputs

This board always has 32 digital inputs. Remove the test when
initializing the subdevice.

Also, since this board is the only one supported by this driver,
remove the boardinfo about the digital inputs and just use the
data directly in the subdevice init.

Subject: [PATCH 1227/3298] staging: comedi: addi_apci_1032: remove unnecessary
 eeprom code

Now that this driver is separate from the "common" addi-data code,
the eeprom does not contain any information required to make this
driver work.

Remove the unneeded initalization of the 's_EeParameters' and the
code that reads the eeprom to fill in the parameters.

Also, since reading the eeprom is not really interesting, remove
the EEPROM subdevice.

 boardinfo

This driver supports only one boardtype. Since this driver uses the
comedi auto attach mechanism, the information left in the boaridnfo
is not required to attach this driver to the comedi subsystem.

Remove the boardinfo data and its use in the driver.

Subject: [PATCH 1232/3298] staging: comedi: addi_apci_1032: fix
 i_APCI1032_ReadMoreDigitalInput()

This function is the insn_bits operation for the digital input subdevice.
According to the comedi API it's supposed return the status of the inputs
in data[1]. The addi-drivers abuse the API and try to make it conform to
their own use.

Fix this function so it follows the comedi API.

This function is the insn_read operation for the digital input subdevice.
This operation can be emulated by the comedi core now that the insn_bits
operation follows the comedi API. Remove this now unnecessary function.

 v_ADDI_Interrupt()

There is no need for this function to call v_APCI1032_Interrupt()
in hwdrv_apci1032.c to reset the board. Just move the code from
v_APCI1032_Interrupt() directly into this function.

Rename the CamelCase function to apci1032_interrupt().

Rename the CamelCase local variable used to read/write the control
register.

Change the return from IRQ_RETVAL(1) to IRQ_HANDLED.

Subject: [PATCH 1238/3298] staging: comedi: addi_apci_1032: add a subdevice
 for the interrupt support

This board supports a single interrupt that can be generated by an AND/OR
combination of 16 of the input channels.

Create a separate subdevice, similar to the comedi_parport driver, to
handle this interrupt.

Move the i_APCI1032_ConfigDigitalInput() operation from the digital
input subdevice to this new subdevice. Rename the CamelCase function
to apci1032_intr_insn_config().

Subject: [PATCH 1239/3298] staging: comedi: addi_apci_1032: remove send_sig()
 use

The addi-data drivers use send_sig() to let the user know when an
interrupt has occurred. The "standard" way to do this in the comedi
subsystem is to have a subdevice that supports asynchronous commands
and use comedi_event() to signal the user.

Remove the send_sig() usage in this driver. This also allows removing
the dev->private usage since tsk_Current was the only member still
being used in the private data.

Subject: [PATCH 1240/3298] staging: comedi: addi_apci_1032: hook-up the
 interrupt subdevice

The board supported by this driver can generate an interrupt based
on the state of input channels 0-15.

The apci1032_intr_insn_config() function is used to configure which
inputs are used to generate the interrupt. Currently this function
is broken since it does not follow the comedi API for insn_config
functions. Fix this function by implementing the, currently unused,
config instruction INSN_CONFIG_DIGITAL_TRIG.

Add the remaining subdevice operations necessary for the interrupt
subdevice to support async commands.

Fix the subdevice initialization so that if the interrupt is not
available the subdevice is set as COMEDI_SUBD_UNUSED.

Subject: [PATCH 1247/3298] ASoC: wm8978: pll incorrectly configured when codec
 is master

When MCLK is supplied externally and BCLK and LRC are configured as outputs
(codec is master), the PLL values are only calculated correctly on the first
transmission.  On subsequent transmissions, at differenct sample rates, the
wrong PLL values are used.  Test for f_opclk instead of f_pllout to determine
if the PLL values are needed.

PCH platforms and VLV should map DPMS standby and suspend modes to off, but

Subject: [PATCH 1252/3298] usb: musb: dsps: reduce musb instance to one

Currently multiple phy's of the same type are not supported, hence
reduce musb instances to one. This helps in supporting at least one
instance of musb, rather than having none. Even without this, it was
observed that both instances were working (by luck), but this holds
good iff wrapper is part of Image. And it is not correct for both
controller's to be associated with same phy, here it was working
because phy is a nop one. And having wrapper as a module and
rmmod'ing would crash.

This can be reverted once multi phy support for same type is available
and driver is enhanced to make use of it.

Subject: [PATCH 1254/3298] usb: musb: dsps: control module handling (quirk)

am335x uses nop transceiver driver and need to enable builtin phy
by writing into usb_ctrl register available in system control
module register space. This is being added at musb glue driver
layer until a separate system control module driver is available.

Proper solution is to make use of control module driver, but it is
not expected to be ready soon.

Other options available are providing control module register space
as memory resource via DT or using omap hwmod.

DT approach has been rejected by Rob Herring, while resources are
being moved from hwmod to DT. And both of the above approaches
require that control module registers be configured in wrapper
itself requring a quirk in driver as well as DT or hwmod.

Here another option is used, providing driver with control module
register physical address. Even though this a hack, there is no other
option left till control module driver is ready. As of now only
am335x is using dsps wrapper, and so driver is made aware of am335x
control module physical address.

Please note that this is a temporary arrangment till omap control
module driver is available.

 usbhsh_hub_status_data()

Because usbhsh_hub_status_data() will be called many times,
there are too many obstructive/useless debug informations if driver has #define DEBUG.
Thus, other important dev_dbg() information will hide.
This patch removed obstructive/useless dev_dbg().

Subject: [PATCH 1257/3298] usb: renesas_usbhs: host: add endpoint user counter

renesas_usbhs attaches pipe to endpoint when urb was queued, and it will be
detached when transfer was done.  Multi device controlling was enabled by this
behavior.

Now renesas_usbhs driver tried to wait until detaching if urb was queued to
endpoint which already has been attached to pipe, and it created strange driver
behavior.

But it can re-use this attached pipe if multi urb was queued.  This patch
implements it.

Subject: [PATCH 1259/3298] usb: musb: remove generic_interrupt

This patch is based on the discussion of a previous patch to fix an issue
where the omap2430 musb driver is not working for N9/N950.

Moving all the interrupt handling to the devices. Avoids inclusion of generic
interrupt and breakage due to sometimes misleading CONFIG options. This makes
sure usb always works if on of the subdrivers is chosen. Tested on Nokia N9/N950.

Partially clean up CONFIG_SOC_OMAP3430 which is not necessary in the cases
where I removed it. Also helps with the removal work of those options that
Tony Lindgren predicted would happen at some point.

Subject: [PATCH 1261/3298] device_cgroup: fix unchecked cgroup parent usage

In 4cef7299b478687 ("device_cgroup: add proper checking when changing
default behavior") the cgroup parent usage is unchecked.  root will not
have a parent and trying to use device.{allow,deny} will cause problems.
For some reason my stressing scripts didn't test the root directory so I
didn't catch it on my regular tests.

Subject: [PATCH 1263/3298] device_cgroup: fix RCU usage

dev_cgroup->exceptions is protected with devcgroup_mutex for writes
and RCU for reads; however, RCU usage isn't correct.

* dev_exception_clean() doesn't use RCU variant of list_del() and
  kfree().  The function can race with may_access() and may_access()
  may end up dereferencing already freed memory.  Use list_del_rcu()
  and kfree_rcu() instead.

* may_access() may be called only with RCU read locked but doesn't use
  RCU safe traversal over ->exceptions.  Use list_for_each_entry_rcu().

Export asm/{svm.h,vmx.h,perf_regs.h} so that they can be disintegrated.

It looks from previous commits that the first two should have been exported,
but the header-y lines weren't added to the Kbuild.

I'm guessing that asm/perf_regs.h should be exported too.

Subject: [PATCH 1276/3298] usb: renesas_usbhs: use transfer counter if IN
 direction bulk pipe

received data will break if it was bulk pipe and large data size,
because pipe kept BUF PID even though it doesn't have enough buffer.
To avoid this issue, renesas_usbhs can use transfer counter.
Pipe PID will be NAK if it didn't have enough buffer by this patch.

renesas_usbhs has strange address mapping.
Thus, it is difficult to calculate transfer counter setting address.
This patch use fixed table for it.

Subject: [PATCH 1277/3298] arch: Change defconfigs to point to g_mass_storage.

The File-backed Storage Gadget (g_file_storage) is being removed, since
it has been replaced by Mass Storage Gadget (g_mass_storage).  This commit
changes defconfigs point to the new gadget.

Subject: [PATCH 1278/3298] usb: gadget: Remove File-backed Storage Gadget
 (g_file_storage).

The File-backed Storage Gadget (g_file_storage) gadget has been replaced
with Mass Storage Gadget (g_mass_storage) which uses the composite
framework.  This commit removes g_file_storage (and most references to it).

- * The File-backed Storage Gadget acts as a USB Mass Storage device,
- * appearing to the host as a disk drive or as a CD-ROM drive.  In addition
- * to providing an example of a genuinely useful gadget driver for a USB
- * device, it also illustrates a technique of double-buffering for increased
- * throughput.  Last but not least, it gives an easy way to probe the
- * behavior of the Mass Storage drivers in a USB host.
- *
- * Backing storage is provided by a regular file or a block device, specified
- * by the "file" module parameter.  Access can be limited to read-only by
- * setting the optional "ro" module parameter.  (For CD-ROM emulation,
- * access is always read-only.)  The gadget will indicate that it has
- * removable media if the optional "removable" module parameter is set.
- *
- * The gadget supports the Control-Bulk (CB), Control-Bulk-Interrupt (CBI),
- * and Bulk-Only (also known as Bulk-Bulk-Bulk or BBB) transports, selected
- * by the optional "transport" module parameter.  It also supports the
- * following protocols: RBC (0x01), ATAPI or SFF-8020i (0x02), QIC-157 (0c03),
- * UFI (0x04), SFF-8070i (0x05), and transparent SCSI (0x06), selected by
- * the optional "protocol" module parameter.  In addition, the default
- * Vendor ID, Product ID, release number and serial number can be overridden.
- *
- * There is support for multiple logical units (LUNs), each of which has
- * its own backing file.  The number of LUNs can be set using the optional
- * "luns" module parameter (anywhere from 1 to 8), and the corresponding
- * files are specified using comma-separated lists for "file" and "ro".
- * The default number of LUNs is taken from the number of "file" elements;
- * it is 1 if "file" is not given.  If "removable" is not set then a backing
- * file must be specified for each LUN.  If it is set, then an unspecified
- * or empty backing filename means the LUN's medium is not loaded.  Ideally
- * each LUN would be settable independently as a disk drive or a CD-ROM
- * drive, but currently all LUNs have to be the same type.  The CD-ROM
- * emulation includes a single data track and no audio tracks; hence there
- * need be only one backing file per LUN.
- *
- * Requirements are modest; only a bulk-in and a bulk-out endpoint are
- * needed (an interrupt-out endpoint is also needed for CBI).  The memory
- * requirement amounts to two 16K buffers, size configurable by a parameter.
- * Support is included for both full-speed and high-speed operation.
- *
- * Note that the driver is slightly non-portable in that it assumes a
- * single memory/DMA buffer will be useable for bulk-in, bulk-out, and
- * interrupt-in endpoints.  With most device controllers this isn't an
- * issue, but there may be some with hardware restrictions that prevent
- * a buffer from being used by more than one endpoint.
- *
- * Module options:
- *
- *	file=filename[,filename...]
- *				Required if "removable" is not set, names of
- *					the files or block devices used for
- *					backing storage
- *	serial=HHHH...		Required serial number (string of hex chars)
- *	ro=b[,b...]		Default false, booleans for read-only access
- *	removable		Default false, boolean for removable media
- *	luns=N			Default N = number of filenames, number of
- *					LUNs to support
- *	nofua=b[,b...]		Default false, booleans for ignore FUA flag
- *					in SCSI WRITE(10,12) commands
- *	stall			Default determined according to the type of
- *					USB device controller (usually true),
- *					boolean to permit the driver to halt
- *					bulk endpoints
- *	cdrom			Default false, boolean for whether to emulate
- *					a CD-ROM drive
- *	transport=XXX		Default BBB, transport name (CB, CBI, or BBB)
- *	protocol=YYY		Default SCSI, protocol name (RBC, 8020 or
- *					ATAPI, QIC, UFI, 8070, or SCSI;
- *					also 1 - 6)
- *	vendor=0xVVVV		Default 0x0525 (NetChip), USB Vendor ID
- *	product=0xPPPP		Default 0xa4a5 (FSG), USB Product ID
- *	release=0xRRRR		Override the USB release number (bcdDevice)
- *	buflen=N		Default N=16384, buffer size used (will be
- *					rounded down to a multiple of
- *					PAGE_CACHE_SIZE)
- *
- * If CONFIG_USB_FILE_STORAGE_TEST is not set, only the "file", "serial", "ro",
- * "removable", "luns", "nofua", "stall", and "cdrom" options are available;
- * default values are used for everything else.
- *
- * The pathnames of the backing files and the ro settings are available in
- * the attribute files "file", "nofua", and "ro" in the lun<n> subdirectory of
- * the gadget's sysfs directory.  If the "removable" option is set, writing to
- * these files will simulate ejecting/loading the medium (writing an empty
- * line means eject) and adjusting a write-enable tab.  Changes to the ro
- * setting are not allowed when the medium is loaded or if CD-ROM emulation
- * is being used.
- *
- * This gadget driver is heavily based on "Gadget Zero" by David Brownell.
- * The driver's SCSI command interface was based on the "Information
- * technology - Small Computer System Interface - 2" document from
- * X3T9.2 Project 375D, Revision 10L, 7-SEP-93, available at
- * <http://www.t10.org/ftp/t10/drafts/s2/s2-r10l.pdf>.  The single exception
- * is opcode 0x23 (READ FORMAT CAPACITIES), which was based on the
- * "Universal Serial Bus Mass Storage Class UFI Command Specification"
- * document, Revision 1.0, December 14, 1998, available at
- * <http://www.usb.org/developers/devclass_docs/usbmass-ufi10.pdf>.

-/*
- *				Driver Design
- *
- * The FSG driver is fairly straightforward.  There is a main kernel
- * thread that handles most of the work.  Interrupt routines field
- * callbacks from the controller driver: bulk- and interrupt-request
- * completion notifications, endpoint-0 events, and disconnect events.
- * Completion events are passed to the main thread by wakeup calls.  Many
- * ep0 requests are handled at interrupt time, but SetInterface,
- * SetConfiguration, and device reset requests are forwarded to the
- * thread in the form of "exceptions" using SIGUSR1 signals (since they
- * should interrupt any ongoing file I/O operations).
- *
- * The thread's main routine implements the standard command/data/status
- * parts of a SCSI interaction.  It and its subroutines are full of tests
- * for pending signals/exceptions -- all this polling is necessary since
- * the kernel has no setjmp/longjmp equivalents.  (Maybe this is an
- * indication that the driver really wants to be running in userspace.)
- * An important point is that so long as the thread is alive it keeps an
- * open reference to the backing file.  This will prevent unmounting
- * the backing file's underlying filesystem and could cause problems
- * during system shutdown, for example.  To prevent such problems, the
- * thread catches INT, TERM, and KILL signals and converts them into
- * an EXIT exception.
- *
- * In normal operation the main thread is started during the gadget's
- * fsg_bind() callback and stopped during fsg_unbind().  But it can also
- * exit when it receives a signal, and there's no point leaving the
- * gadget running when the thread is dead.  So just before the thread
- * exits, it deregisters the gadget driver.  This makes things a little
- * tricky: The driver is deregistered at two places, and the exiting
- * thread can indirectly call fsg_unbind() which in turn can tell the
- * thread to exit.  The first problem is resolved through the use of the
- * REGISTERED atomic bitflag; the driver will only be deregistered once.
- * The second problem is resolved by having fsg_unbind() check
- * fsg->state; it won't try to stop the thread if the state is already
- * FSG_STATE_TERMINATED.
- *
- * To provide maximum throughput, the driver uses a circular pipeline of
- * buffer heads (struct fsg_buffhd).  In principle the pipeline can be
- * arbitrarily long; in practice the benefits don't justify having more
- * than 2 stages (i.e., double buffering).  But it helps to think of the
- * pipeline as being a long one.  Each buffer head contains a bulk-in and
- * a bulk-out request pointer (since the buffer can be used for both
- * output and input -- directions always are given from the host's
- * point of view) as well as a pointer to the buffer and various state
- * variables.
- *
- * Use of the pipeline follows a simple protocol.  There is a variable
- * (fsg->next_buffhd_to_fill) that points to the next buffer head to use.
- * At any time that buffer head may still be in use from an earlier
- * request, so each buffer head has a state variable indicating whether
- * it is EMPTY, FULL, or BUSY.  Typical use involves waiting for the
- * buffer head to be EMPTY, filling the buffer either by file I/O or by
- * USB I/O (during which the buffer head is BUSY), and marking the buffer
- * head FULL when the I/O is complete.  Then the buffer will be emptied
- * (again possibly by USB I/O, during which it is marked BUSY) and
- * finally marked EMPTY again (possibly by a completion routine).
- *
- * A module parameter tells the driver to avoid stalling the bulk
- * endpoints wherever the transport specification allows.  This is
- * necessary for some UDCs like the SuperH, which cannot reliably clear a
- * halt on a bulk endpoint.  However, under certain circumstances the
- * Bulk-only specification requires a stall.  In such cases the driver
- * will halt the endpoint and set a flag indicating that it should clear
- * the halt in software during the next device reset.  Hopefully this
- * will permit everything to work correctly.  Furthermore, although the
- * specification allows the bulk-out endpoint to halt when the host sends
- * too much data, implementing this would cause an unavoidable race.
- * The driver will always use the "no-stall" approach for OUT transfers.
- *
- * One subtle point concerns sending status-stage responses for ep0
- * requests.  Some of these requests, such as device reset, can involve
- * interrupting an ongoing file I/O operation, which might take an
- * arbitrarily long time.  During that delay the host might give up on
- * the original ep0 request and issue a new one.  When that happens the
- * driver should not notify the host about completion of the original
- * request, as the host will no longer be waiting for it.  So the driver
- * assigns to each ep0 request a unique tag, and it keeps track of the
- * tag value of the request associated with a long-running exception
- * (device-reset, interface-change, or configuration-change).  When the
- * exception handler is finished, the status-stage response is submitted
- * only if the current ep0 request tag is equal to the exception request
- * tag.  Thus only the most recently received ep0 request will get a
- * status-stage response.
- *
- * Warning: This driver source file is too long.  It ought to be split up
- * into a header file plus about 3 separate .c files, to handle the details
- * of the Gadget, USB Mass Storage, and SCSI protocols.

Subject: [PATCH 1279/3298] usb: gadget: storage_common: Remove FSG specific
 definitions.

Since g_file_storage has been removed, this commit removes code from
the storage_common.c file which has been used by file_storage.c only
(and not by f_mass_storage.c).

 #ifdef DUMP_MSGS

Subject: [PATCH 1280/3298] usb: gadget: storage_common: Drop #ifdefs used for
 the sake of FSG.

storage_common.c has been used by both file_storage.c and f_mass_storage.c
which had some different requirements in a few places.  To accomodate for
that, storage_common.c provided configuratian macros which were to be
defined (or not) prior to the file #inclusion.  Because now
file_storage.c is no longer with us, we can remove support for those
macros and thus simplify the code slightly.

 a function.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since function-line macros are to be avoided, this commit replaces
the fsg_lun_is_open() macro with a static inline function.

While at it, this commit also adds “inline” modifier to the
fsg_lun_from_dev() function.

Subject: [PATCH 1282/3298] usb: gadget: Remove reference to is_dualspeed from
 sysfs.

This commit removes the /sys/devices/platform/<UDC>/udc/<UDC>/is_dualspeed
file and is_dualspeeed line from /sys/devices/platform/ci13xxx_*/udc/device
file.

The is_dualspeed file is superseded by maximum_speed in the same directory
and is_dualspeed line in device file is superseded by max_speed line in
the same file.

The maximum_speed/max_speed specifies maximum speed supported by UDC.
To check if dualspeeed is supported, check if the value is >= 3.

Subject: [PATCH 1283/3298] usb: gadget: g_ether: fix frame size check

Checking skb->len against ETH_FRAME_LEN assumes a 1514
ethernet frame size. With an 802.1Q VLAN header, ethernet
frame length can now be 1518. Validate frame length against that.

Subject: [PATCH 1292/3298] rcu: Document alternative RCU/reference-count
 algorithms

The approach for mixing RCU and reference counting listed in the RCU
documentation only describes one possible approach.  This approach can
result in failure on the read side, which is nice if you want fresh data,
but not so good if you want simple code.  This commit therefore adds
two additional approaches that feature unconditional reference-count
acquisition by RCU readers.  These approaches are very similar to that
used in the security code.

+
+The key point is that the initial reference added by add() is not removed
+until after a grace period has elapsed following removal.  This means that
+search_and_reference() cannot find this element, which means that the value
+of el->rc cannot increase.  Thus, once it reaches zero, there are no
+readers that can or ever will be able to reference the element.  The
+element can therefore safely be freed.  This in turn guarantees that if
+any reader finds the element, that reader may safely acquire a reference
+without checking the value of the reference counter.
+
+In cases where delete() can sleep, synchronize_rcu() can be called from
+delete(), so that el_free() can be subsumed into delete as follows:
+
+4.
+delete()
+{
+    spin_lock(&list_lock);
+    ...
+    remove_element
+    spin_unlock(&list_lock);

The ->onofflock field in the rcu_state structure at one time synchronized
CPU-hotplug operations for RCU.  However, its scope has decreased over time
so that it now only protects the lists of orphaned RCU callbacks.  This
commit therefore renames it to ->orphan_lock to reflect its current use.

Subject: [PATCH 1294/3298] rcu: Avoid counter wrap in
 synchronize_sched_expedited()

There is a counter scheme similar to ticket locking that
synchronize_sched_expedited() uses to service multiple concurrent
callers with the same expedited grace period.  Upon entry, a
sync_sched_expedited_started variable is atomically incremented,
and upon completion of a expedited grace period a separate
sync_sched_expedited_done variable is atomically incremented.

However, if a synchronize_sched_expedited() is delayed while
in try_stop_cpus(), concurrent invocations will increment the
sync_sched_expedited_started counter, which will eventually overflow.
If the original synchronize_sched_expedited() resumes execution just
as the counter overflows, a concurrent invocation could incorrectly
conclude that an expedited grace period elapsed in zero time, which
would be bad.  One could rely on counter size to prevent this from
happening in practice, but the goal is to formally validate this
code, so it needs to be fixed anyway.

This commit therefore checks the gap between the two counters before
incrementing sync_sched_expedited_started, and if the gap is too
large, does a normal grace period instead.  Overflow is thus only
possible if there are more than about 3.5 billion threads on 32-bit
systems, which can be excluded until such time as task_struct fits
into a single byte and 4G/4G patches are accepted into mainline.
It is also easy to encode this limitation into mechanical theorem
provers.

Subject: [PATCH 1295/3298] rcu: Move synchronize_sched_expedited() state to
 rcu_state

Tracing (debugfs) of expedited RCU primitives is required, which in turn
requires that the relevant data be located where the tracing code can find
it, not in its current static global variables in kernel/rcutree.c.
This commit therefore moves sync_sched_expedited_started and
sync_sched_expedited_done to the rcu_state structure, as fields
->expedited_start and ->expedited_done, respectively.

Subject: [PATCH 1297/3298] rcu: Create directory for each flavor of rcu

This patch will create subdirectory according to each flavor of rcu, the new
structure will be:

	/debugfs/rcu/ -> rsp_0
		      -> rsp_1
		      -> ...

So we can go to '/debugfs/rcu/rsp_0' and get the cpu info of rsp_0 there.
The flavors of RCU are currently rcu_bh, rcu_preempt, and rcu_sched.

Subject: [PATCH 1298/3298] rcu: Fundamental facility for 'CPU units sequence
 reading'

This patch add the fundamental facility used by the following patches, so we
can implement the 'CPU units sequence reading' later.

This helps us avoid losing data when there are too many CPUs and too
small of a buffer, since this new approach allows userspace to read out
the data one CPU at a time.  Thus, if the buffer is not large enough,
userspace will get whatever CPUs fit, and can then issue another read
for the remainder of the data.

Subject: [PATCH 1304/3298] rcu: Fix tracing formatting

The rcu_state structure's ->completed field is unsigned long, so this
commit adjusts show_one_rcugp()'s printf() format to suit.  Also add
the required ACCESS_ONCE() directives while we are in this function.

Subject: [PATCH 1309/3298] rcu: Remove old debugfs interfaces and also RCU
 flavor name

This commit removes the old debugfs interfaces, so that the new
directory-per-RCU-flavor versions remain.  Because the RCU flavor is
given by the directory name, there is no need to print it out, so remove
the name from the printout.

Subject: [PATCH 1311/3298] perf tools: Don't try to lookup objdump for live
 mode

Arnaldo reported that annotation during perf top resulted in a segfault.
It was because the env->arch was NULL and we don't set it for a live
session.  In fact, no need to look up objdump in this case since we can
use system's default (native) objdump.

Subject: [PATCH 1312/3298] perf diff: Start moving to support matching more
 than two hists

We want to match more than two hists, so that we can match more than two
perf.data files and moreover, match hist_entries (buckets) in multiple
events in a group.

So the "baseline"/"leader" will instead of a ->pair pointer, use a
list_head, that will link to the pairs and hists__match use it.

Following that perf_evlist__link will link the hists in its evsel
groups.

Subject: [PATCH 1314/3298] perf hists: Introduce hists__link

That given two hists will find the hist_entries (buckets) in the second
hists that are for the same bucket in the first and link them, then it
will look for all buckets in the second that don't have a counterpart in
the first and will create a dummy counterpart that will then be linked
to the entry in the second.

For multiple events this will be done pairing the leader with all the
other events in the group, so that in the end the leader will have all
the buckets in all the hists in a group, dummy or not while the other
hists will be left untouched.

Previously there were blind spots because we were not looking at symbols
that didn't ocurred in the latest run:

  [ perf record: Captured and wrote 0.018 MB perf.data (~801 samples) ]
  # perf record usleep 1

Before:

Subject: [PATCH 1316/3298] gpio: tegra: fix suspend/resume apis

Following are changes done to fix the suspend/resume
functionality of tegra gpio driver:
- Protect suspend/resume callbacks with CONFIG_PM_SLEEP
  because CONFIG_PM doesn't actually enable any of the PM callbacks, it
  only allows to enable CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME.
  This means if CONFIG_PM is used to protect system sleep callbacks
  then it may end up unreferenced if only runtime PM is enabled.

- Fix the suspend/resume APIs declaration as per callback prototype.

 creation"

This reverts commit d8c3ef256f88b7c6ecd673d03073b5645be9c5e4.

Above mentioned change was made along with multi usb phy change and
adding DT support for nop transceiver. But other two changes did not
make it to mainline. This in effect makes dsps musb wrapper unusable
even for single instance.

Hence revert it so that at least single instance can be supported.

Commit d065bd810b6deb67d4897a14bfe21f8eb526ba99
(mm: retry page fault when blocking on disk transfer) and
commit 37b23e0525d393d48a7d59f870b3bc061a30ccdb
(x86,mm: make pagefault killable)

The above commits introduced changes into the x86 pagefault handler
for making the page fault handler retryable as well as killable.

These changes reduce the mmap_sem hold time, which is crucial
during OOM killer invocation.

Port these changes to unicore32.

Subject: [PATCH 1331/3298] arch/unicore32: remove CONFIG_EXPERIMENTAL

This config item has not carried much meaning for a while now and is
almost always enabled by default. As agreed during the Linux kernel
summit, remove it.

Subject: [PATCH 1333/3298] MIPS: compat: Implement is_compat_task() by testing
 for 32-bit address space.

So far is_compat_task() was testing for 32-bit registers if O32 support
was enabled and if O32 support was disabled but N32 enabled it was testing
for 32-bit address space.  So if both O32 and N32 were enabled a N32
task was not considered a compat task, whops.

This still leaves potential cases where O32 and N32 need different treatment
unsolved.  But that's another commit.

Subject: [PATCH 1336/3298] MIPS: Remove irqflags.h dependency from bitops.h

The "else clause" of most functions in bitops.h invoked
raw_local_irq_{save,restore}() and in doing so had a dependency on
irqflags.h.  This fix moves said code to bitops.c, removing the
dependency.

Subject: [PATCH 1337/3298] MIPS: Make irqflags.h functions preempt-safe for
 non-mipsr2 cpus

For non MIPSr2 processors, such as the BMIPS 5000, calls to
arch_local_irq_disable() and others may be preempted, and in doing
so a stale value may be restored to c0_status.  This fix disables
preemption for such processors prior to the call and enables it
after the call.

Those functions that needed this fix have been "outlined" to
mips-atomic.c, as they are no longer good candidates for inlining.

This bug was observed in a BMIPS 5000, occuring once every few hours
in a continuous reboot test.  It was traced to the write_lock_irq()
function which was being invoked in release_task() in exit.c.
By placing a number of "nops" inbetween the mfc0/mtc0 pair in
arch_local_irq_disable(), which is called by write_lock_irq(), we
were able to greatly increase the occurance of this bug.  Similarly,
the application of this commit silenced the bug.

Subject: [PATCH 1338/3298] pinctrl/nomadik: make independent of prcmu driver

Currently there are some unnecessary criss-cross
dependencies between the PRCMU driver in MFD and a lot of
other drivers, mainly because other drivers need to poke
around in the PRCM register range.

In cases like this there are actually just a few select
registers that the pinctrl driver need to read/modify/write,
and it turns out that no other driver is actually using
these registers, so there are no concurrency issues
whatsoever.

So: don't let the location of the register range complicate
things, just poke into these registers directly and skip
a layer of indirection.

Take this opportunity to add kerneldoc to the pinctrl
state container.

Subject: [PATCH 1341/3298] [media] dvb_usb_v2: switch interruptible mutex to
 normal

Fixes error: dvb_usb_v2: pid_filter() failed=-4

error code -4 is EINTR, Interrupted system call

That error blocks I/O in some cases as -EINTR error was returned
by the mutex which was protecting USB control messages. We want
configure hardware to sleep mode on every case after tuning is
stopped. That kind of behavior blocks it, leaving hardware some
unwanted state in worst case.

That error was seen every time when af9015 was plugged to USB1.1
which leads use of hardware PID filters. Stop tuning (tzap) with
ctrl+c failed as driver tries to remove hardware PID filters.

Tested with every hardware which uses routine in question.

Subject: [PATCH 1342/3298] perf test: fix a build error on builtin-test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recently I build perf and get a build error on builtin-test.c. The error is as
following:

$ make
    CC perf.o
    CC builtin-test.o
cc1: warnings being treated as errors
builtin-test.c: In function ‘sched__get_first_possible_cpu’:

builtin-test.c:998: warning: implicit declaration of function ‘CPU_CLR_S’
builtin-test.c:998: warning: nested extern declaration of ‘CPU_CLR_S’
make: *** [builtin-test.o] Error 1

This problem is introduced in 3e7c439a. CPU_ALLOC and related macros are
missing in sched__get_first_possible_cpu function. In 54489c18, commiter
mentioned that CPU_ALLOC has been removed. So CPU_ALLOC calls in this
function are removed to let perf to be built.

Subject: [PATCH 1345/3298] jffs2: Fix lock acquisition order bug in
 jffs2_write_begin

jffs2_write_begin() first acquires the page lock, then f->sem. This
causes an AB-BA deadlock with jffs2_garbage_collect_live(), which first
acquires f->sem, then the page lock:

jffs2_garbage_collect_live
    mutex_lock(&f->sem)                         (A)
    jffs2_garbage_collect_dnode
        jffs2_gc_fetch_page
            read_cache_page_async
                do_read_cache_page
                    lock_page(page)             (B)

jffs2_write_begin
    grab_cache_page_write_begin
        find_lock_page
            lock_page(page)                     (B)
    mutex_lock(&f->sem)                         (A)

We fix this by restructuring jffs2_write_begin() to take f->sem before
the page lock. However, we make sure that f->sem is not held when
calling jffs2_reserve_space(), as this is not permitted by the locking
rules.

The deadlock above was observed multiple times on an SoC with a dual
ARMv7 (Cortex-A9), running the long-term 3.4.11 kernel; it occurred
when using scp to copy files from a host system to the ARM target
system. The fix was heavily tested on the same target system.

Subject: [PATCH 1346/3298] Bluetooth: Fix having bogus entries in
 mgmt_read_index_list reply

The mgmt_read_index_list uses one loop to calculate the max needed size
of its response with the help of an upper-bound of the controller count.
The second loop is more strict as it checks for HCI_SETUP (which might
have gotten set after the first loop) and could result in some indexes
being skipped. Because of this the function needs to readjust the event
length and index count after filling in the response array.

Subject: [PATCH 1347/3298] Bluetooth: Fix error status when pairing fails
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When pairing fails due to wrong confirm value, the management layer
doesn't report a proper error status. It sends
MGMT_STATUS_CONNECT_FAILED instead of MGMT_STATUS_AUTH_FAILED.

Most of management functions that receive a status as a parameter
expects for it to be encoded as a HCI status. But when a SMP pairing
fails, the SMP layer sends the SMP reason as the error status to the
management layer.

This commit maps all SMP reasons to HCI_ERROR_AUTH_FAILURE, which will
be converted to MGMT_STATUS_AUTH_FAILED in the management layer.

Subject: [PATCH 1348/3298] Bluetooth: Notify about device registration before

It is important that the monitor interface gets notified about
a new device before its power on procedure has been started.

For some reason that is no longer working as expected and the power
on procedure runs first. It is safe to just notify about device
registration and trigger the power on procedure afterwards.

Subject: [PATCH 1355/3298] perf annotate: Don't try to follow jump target on
 PLT symbols

The perf annotate browser on TUI can identify a jump target for a
selected instruction.  It assumes that the jump target is within the
function but it's not the case of PLT symbols which have offset out of
the function as a target.

Since it caused a segmentation fault, do not try to follow jump target
on the PLT symbols.

Subject: [PATCH 1356/3298] perf annotate: Merge same lines in summary view

The --print-line option of perf annotate command shows summary for
each source line.  But it didn't merge same lines so that it can
appear multiple times.

* before:

To do that, introduce percent_sum field so that the normal
line-by-line output doesn't get changed.

This is because:

          enum pevent_func_arg_type type;

this enum doesn't have any negative value, so gcc makes it an 'unsigned

Subject: [PATCH 1365/3298] cpufreq: db8500: Fetch cpufreq table from platform
 data

By fetching the table as platform data we do not need the internally
hardcoded cpufreq table anymore.

Moreover the corresponding arm_opp idx2opp table, used for mapping
frequency to correct opp bits is also removed. This due to that the
opp bits is put directly in the index field of the cpufreq table.

Subject: [PATCH 1366/3298] mfd: db8500: Connect ARMSS clk to ARM OPP

ARMSS clk directly maps it's frequency towards the cpufreq table.
To be able to update the ARMSS clk rate, a new set_rate function for
the ARMSS clk is added, which also will trigger a corresponding ARM
OPP request. Additionally an ARMSS clk round_rate function is added
to fetch valid cpufreq frequencies.

Subject: [PATCH 1368/3298] clk: ux500: Add armss clk and fixup smp_twd clk for
 u8500

The new armss clk is a prcmu_scalable_rate clk which represents
the ARMSS clk. This then makes it possible to convert the smp_twd
clk to a fixed factor clock type, using a fixed divider of 2 and
with the armss clk as parent.

Subject: [PATCH 1370/3298] clk: fix return value check in
 bcm2835_init_clocks()

In case of error, the function clk_register_fixed_rate() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().

This callback buffer is meant to be opaque to users, but basically
adds a very simple pass through buffer to which data may be
pushed when it is inserted into the buffer list.

Subject: [PATCH 1382/3298] staging:iio:adc:max1363 consolidate files.

For a long while now the max1363 core has selected the
buffer anyway. For a while I meant to make the separation
work again, but given how long it has been it is probably
time to conclude it will never happen and settle for tidying
up what we have.

Subject: [PATCH 1386/3298] staging:iio:adc:max1363 cleanup regulator handling.

For historical reasons the regulator handling was a little clunky. This
patch brings it inline with a more standard ordering wrt to allocation
of the iio_device.

Subject: [PATCH 1390/3298] of/fdt: Don't copy garbage after "/" in root node
 path

The root node path must be internally converted to "/", or various
pieces of code looking for it that way will fail. The code to do
that however had a bug where we might incorrectly append pieces
of the original path from the fdt to the "/".

We should probably add a proper dedicated accessor for the root node
but in the meantime this patch should fix it.

Subject: [PATCH 1392/3298] pinctrl: reserve pins when states are activated

This switches the way that pins are reserved for multiplexing:

We used to do this when the map was parsed, at the creation of
the settings inside the pinctrl handle, in pinmux_map_to_setting().

However this does not work for us, because we want to use the
same set of pins with different devices at different times: the
current code assumes that the pin groups in a pinmux state will
only be used with one single device, albeit different groups can
be active at different times. For example if a single I2C driver
block is used to drive two different busses located on two
pin groups A and B, then the pins for all possible states of a
function are reserved when fetching the pinctrl handle: the
I2C bus can choose either set A or set B by a mux state at
runtime, but all pins in both group A and B (the superset) are
effectively reserved for that I2C function and mapped to the
device. Another device can never get in and use the pins in
group A, even if the device/function is using group B at the
moment.

Instead: let use reserve the pins when the state is activated
and drop them when the state is disabled, i.e. when we move to
another state. This way different devices/functions can use the
same pins at different times.

We know that this is an odd way of doing things, but we really
need to switch e.g. an SD-card slot to become a tracing output
sink at runtime: we plug in a special "tracing card" then mux
the pins that used to be an SD slot around to the tracing
unit and push out tracing data there instead of SD-card
traffic.

As a side effect pinmux_free_setting() is unused but the stubs
are kept for future additions of code.

Subject: [PATCH 1393/3298] pinctrl: mvebu: allow plat-orion architectures to
 use pinctrl-mvebu

The mach-kirkwood and mach-dove architectures have not yet been
integrated into the mach-mvebu directory, which should ultimately
contain the support for all Marvell SoCs from the Engineering Business
Unit.

However, before this can happen, we need to let mach-kirkwood and
mach-dove use the pinctrl-mvebu driver, which supports the kirkwood
and dove SoC families. In order to do that, we make this driver
available as soon as PLAT_ORION is selected, instead of using
ARCH_MVEBU as a condition. In the long term, PLAT_ORION should
disappear and be fully replaced by ARCH_MVEBU, but the plan is to make
the migration step by step, by first having the existing mach-*
directories for Marvell SoCs converge on several infrastructures,
including the pinctrl one.

Also, like the spear pinctrl driver, we put all pinctrl-mvebu Kconfig
options under a if, in order to avoid having certain options
(PINCTRL_DOVE, PINCTRL_KIRKWOOD, etc.) selecting an option
(PINCTLR_MVEBU) which itself has a dependency (on ARCH_MVEBU). In this
a construct, the dependency is in fact ignored due to the selects.

Subject: [PATCH 1395/3298] pinctrl: mvebu: move to its own directory

Like the spear platform, the mvebu platform has multiple files: one
core file, and then one file per SoC family. More files will be added
later, as support for mach-orion5x and mach-mv78xx0 SoCs is added to
pinctrl-mvebu. For those reasons, having a separate subdirectory,
drivers/pinctrl/mvebu/ makes sense, and it had already been suggested
by Linus Wallej when the driver was originally submitted.

Subject: [PATCH 1396/3298] pinctrl: sirf: enable the driver support new
 SiRFmarco SoC

The driver supports old up SiRFprimaII SoCs, this patch makes it support
the new SiRFmarco as well.
SiRFmarco, as a SMP SoC, adds new SIRFSOC_GPIO_PAD_EN_CLR registers, to
disable GPIO pad, we should write 1 to the corresponding bit in the new
CLEAR register instead of writing 0 to SIRFSOC_GPIO_PAD_EN.

Subject: [PATCH 1398/3298] Revert "pinctrl: remove pinctrl_remove_gpio_range"

This reverts earlier commit which removed
pinctrl_remove_gpio_range(), because at that time there
weren't any more users of that routine. It was removed as the
removal of ranges was done in unregister of pinctrl.

But as we are now registering stuff from gpiolib, we may
remove and insert a gpio module multiple times. So, we
need this routine again.

Subject: [PATCH 1399/3298] gpiolib: provide provision to register pin ranges

pinctrl subsystem needs gpio chip base to prepare set of gpio
pin ranges, which a given pinctrl driver can handle. This is
important to handle pinctrl gpio request calls in order to
program a given pin properly for gpio operation.

As gpio base is allocated dynamically during gpiochip
registration, presently there exists no clean way to pass this
information to the pinctrl subsystem.

After few discussions from [1], it was concluded that may be
gpio controller reporting the pin range it supports, is a
better way than pinctrl subsystem directly registering it.

+GPIO controllers and the pinctrl subsystem
+------------------------------------------
+
+A GPIO controller on a SOC might be tightly coupled with the pinctrl
+subsystem, in the sense that the pins can be used by other functions
+together with an optional gpio feature. We have already covered the
+case where e.g. a GPIO controller need to reserve a pin or set the
+direction of a pin by calling any of:
+
+pinctrl_request_gpio()
+pinctrl_free_gpio()
+pinctrl_gpio_direction_input()
+pinctrl_gpio_direction_output()
+
+But how does the pin control subsystem cross-correlate the GPIO
+numbers (which are a global business) to a certain pin on a certain
+pin controller?
+
+This is done by registering "ranges" of pins, which are essentially
+cross-reference tables. These are described in
+Documentation/pinctrl.txt
+
+While the pin allocation is totally managed by the pinctrl subsystem,
+gpio (under gpiolib) is still maintained by gpio drivers. It may happen
+that different pin ranges in a SoC is managed by different gpio drivers.
+
+This makes it logical to let gpio drivers announce their pin ranges to
+the pin ctrl subsystem before it will call 'pinctrl_request_gpio' in order
+to request the corresponding pin to be prepared by the pinctrl subsystem
+before any gpio usage.
+
+For this, the gpio controller can register its pin range with pinctrl
+subsystem. There are two ways of doing it currently: with or without DT.
+
+For with DT support refer to Documentation/devicetree/bindings/gpio/gpio.txt.
+
+For non-DT support, user can call gpiochip_add_pin_range() with appropriate
+parameters to register a range of gpio pins with a pinctrl driver. For this
+exact name string of pinctrl device has to be passed as one of the
+argument to this routine.
+
+

Subject: [PATCH 1401/3298] ARM: U300: bump IRQs to offset 32

The U300 IRQs were bumped once to offset to 1 (in order to avoid
using IRQ 0 which is now NO_IRQ). This was OK as we were still
passing the number of irqs in the .nr_irqs field of the machine,
with descriptors allocated at boot time.

However .nr_irqs should be 0, leading the system to reserve the
first 16 IRQs. Then the VIC driver will complain that IRQs 1
thru 15 are pre-allocated, so to avoid this and use free
descriptors, move all IRQs up to offset 32.

This will all be done away with as we migrate to device tree,
so it is an interim solution.

Subject: [PATCH 1402/3298] pinctrl/coh901: use irqdomain, allocate irqdescs

This switches the COH 901 pinctrl driver to allocate its GPIO
IRQs dynamically, and start to use a linear irqdomain to map
from the hardware IRQs.

This way we can cut away the complex allocation of IRQ numbers
from the <mach/irqs.h> file.

Subject: [PATCH 1407/3298] gpiolib: fix up function prototypes etc

Commit 69e1601bca88809dc118abd1becb02c15a02ec71
"gpiolib: provide provision to register pin ranges"

Got most of it's function prototypes wrong, so fix this up by:

- Moving the void declarations into static inlines in
  <linux/gpio.h> (previously the actual prototypes were declared
  here...)

- Declare the gpiochip_add_pin_range() and
  gpiochip_remove_pin_ranges() functions in <asm-generic/gpio.h>
  together with the pin range struct declaration itself.

- Actually only implement these very functions in gpiolib.c
  if CONFIG_PINCTRL is set.

- Additionally export the symbols since modules will need to
  be able to do this.

gpiochip_remove_pin_ranges(). But the contents are exactly
the same so remove the OF one and rely on the range deletion
in the core.

Subject: [PATCH 1410/3298] gpiolib: call pin removal in chip removal function

This makes us call gpiochio_remove_pin_ranges() in the
gpiochip_remove() function, so we get rid of ranges when
freeing the chip.

Subject: [PATCH 1411/3298] gpiolib: separation of pin concerns

The fact that of_gpiochip_add_pin_range() and
gpiochip_add_pin_range() share too much code is fragile and
will invariably mean that bugs need to be fixed in two places
instead of one.

So separate the concerns of gpiolib.c and gpiolib-of.c and
have the latter call the former as back-end. This is necessary
also when going forward with other device descriptions such
as ACPI.

This is done by:

- Adding a return code to gpiochip_add_pin_range() so we can
  reliably check whether this succeeds.

- Get rid of the custom of_pinctrl_add_gpio_range() from
  pinctrl. Instead create of_pinctrl_get() to just retrive the
  pin controller per se from an OF node. This composite
  function was just begging to be deleted, it was way to
  purpose-specific.

- Use pinctrl_dev_get_name() to get the name of the retrieved
  pin controller and use that to call back into the generic
  gpiochip_add_pin_range().

Now the pin range is only allocated and tied to a pin
controller from the core implementation in gpiolib.c.

Subject: [PATCH 1412/3298] gpiolib: iron out include ladder mistakes

The <*/gpio.h> includes are updated again: now we need to account
for the problem introduced by commit:
595679a8038584df7b9398bf34f61db3c038bfea
"gpiolib: fix up function prototypes etc"

Actually we need static inlines in include/asm-generic/gpio.h
as well since we may have GPIOLIB but not PINCTRL.
Make sure to move all the CONFIG_PINCTRL business
to the end of the file so we are sure we have
declared struct gpio_chip.

And we need to keep the static inlines in <linux/gpio.h>
but here for the !CONFIG_GENERIC_GPIO case, and then we
may as well throw in a few warnings like the other
prototypes there, if someone would have the bad taste
of compiling without GENERIC_GPIO even.

Subject: [PATCH 1416/3298] pinctrl: SPEAr: Add SoC specific gpio configuration
 routines

Different SPEAr SoCs have different approach to configure pins as gpios. Some
configure a group of gpios with single register bit and others have one bit per
gpio pin. Only earlier one is implemented till now, this patch adds support for
later one.

Here we add callbacks to SoC specific code to configure gpios in
gpio_request_enable(). That will do additional SoC specific configuration to
enable gpio pins.

We also implement this callback for SPEAr1340 in this patch.

Subject: [PATCH 1417/3298] pinctrl: lantiq: Remove ltq_pmx_disable() function

Current code adds empty ltq_pmx_disable() because pinmux_check_ops() requires
this callback to be defined.

This is not required since commit 02b50ce4cb1
"pinctrl: make pinmux disable function optional".

Thus remove ltq_pmx_disable() function.

Miles Lane has reported seeing similar splats during system suspend.

The mutex in struct led_trigger_cpu appears to have no function: it
resides in a per-cpu data structure which never changes after the
trigger is registered.  So just remove it.

(1<<optname) is undefined behavior in C with a negative optname or
optname larger than 31.  In those cases the result of the shift is
not necessarily zero (e.g., on x86).

This patch simplifies the code with a switch statement on optname.
It also allows the compiler to generate better code (e.g., using a
64-bit mask).

Subject: [PATCH 1422/3298] USB: fix endpoint-disabling for failed config
 changes

This patch (as1631) fixes a bug that shows up when a config change
fails for a device under an xHCI controller.  The controller needs to
be told to disable the endpoints that have been enabled for the new
config.  The existing code does this, but before storing the
information about which endpoints were enabled!  As a result, any
second attempt to install the new config is doomed to fail because
xhci-hcd will refuse to enable an endpoint that is already enabled.

The patch optimistically initializes the new endpoints' device
structures before asking the device to switch to the new config.  If
the request fails then the endpoint information is already stored, so
we can use usb_hcd_alloc_bandwidth() to disable the endpoints with no
trouble.  The rest of the error path is slightly more complex now; we
have to disable the new interfaces and call put_device() rather than
simply deallocating them.

Subject: [PATCH 1423/3298] USB: EHCI: miscellaneous cleanups for the library
 conversion

This patch (as1630) cleans up a few minor items resulting from the
split-up of the ehci-hcd driver:

	Remove the product_desc string from the ehci_driver_overrides
	structure.  All drivers will use the generic "EHCI Host
	Controller" string.  (This was requested by Felipe Balbi.)

	Allow drivers to pass a NULL pointer to ehci_init_driver()
	if they don't have to override any settings.

	Remove a #define symbol that is no longer used from the
	ChipIdea host driver.

	Rename overrides to pci_overrides in ehci-pci.c, for
	consistency with ehci-platform.c.

	Mark the *_overrides structures as __initdata.

Subject: [PATCH 1424/3298] USB: EHCI: bugfix: urb->hcpriv should not be NULL

This patch (as1632b) fixes a bug in ehci-hcd.  The USB core uses
urb->hcpriv to determine whether or not an URB is active; host
controller drivers are supposed to set this pointer to a non-NULL
value when an URB is queued.  However ehci-hcd sets it to NULL for
isochronous URBs, which defeats the check in usbcore.

In itself this isn't a big deal.  But people have recently found that
certain sequences of actions will cause the snd-usb-audio driver to
reuse URBs without waiting for them to complete.  In the absence of
proper checking by usbcore, the URBs get added to their endpoint list
twice.  This leads to list corruption and a system freeze.

The patch makes ehci-hcd assign a meaningful value to urb->hcpriv for
isochronous URBs.  Improving robustness always helps.

It can be legitimately triggered via procfs access.  Now, at least
2 of 3 of get_files_struct() callers in procfs are useless, but
when and if we get rid of those we can always add WARN_ON() here.
BUG_ON() at that spot is simply wrong.

support for MS 3k keyboards. However the added check using memcmp and
a compound statement breaks build on architectures where memcmp is a
macro with parameters.

hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3

On x86_64, memcmp is a function, so I did not see the error.

Subject: [PATCH 1431/3298] s390/signal: set correct address space control

If user space is running in primary mode it can switch to secondary
or access register mode, this is used e.g. in the clock_gettime code
of the vdso. If a signal is delivered to the user space process while
it has been running in access register mode the signal handler is
executed in access register mode as well which will result in a crash
most of the time.

Set the address space control bits in the PSW to the default for the
execution of the signal handler and make sure that the previous
address space control is restored on signal return. Take care
that user space can not switch to the kernel address space by
modifying the registers in the signal frame.

Subject: [PATCH 1432/3298] s390/topology: fix core id vs physical package id
 mix-up

The current topology code confuses core id vs physical package id.

In other words /sys/devices/system/cpu/cpuX/topology/core_id
displays the physical_package_id (aka socket id) instead of the
core id.
The physical_package_id sysfs attribute always displays "-1"
instead of the socket id.

Fix this mix-up with a small patch which defines and initializes
topology_physical_package_id correctly and fixes the broken
core id handling.

When in world roaming mode, allow 40 MHz to be used
on channels 12 and 13 so that an AP that is, e.g.,
using HT40+ on channel 9 (in the UK) can be used.

Subject: [PATCH 1439/3298] genirq: Always force thread affinity

Sankara reported that the genirq core code fails to adjust the
affinity of an interrupt thread in several cases:

 1) On request/setup_irq() the call to setup_affinity() happens before
    the new action is registered, so the new thread is not notified.

 2) For secondary shared interrupts nothing notifies the new thread to
    change its affinity.

 3) Interrupts which have the IRQ_NO_BALANCE flag set are not moving
    the thread either.

Fix this by setting the thread affinity flag right on thread creation
time. This ensures that under all circumstances the thread moves to
the right place. Requires a check in irq_thread_check_affinity for an
existing affinity mask (CONFIG_CPU_MASK_OFFSTACK=y)

 intel_sdvo_init() failures

Any failures in intel_sdvo_init() after the intel_sdvo_setup_output() call
left behind ghost connectors, attached (with a dangling pointer) to the
sdvo that has been cleaned up and freed. Properly destroy any connectors
attached to the encoder.

Subject: [PATCH 1442/3298] xhci: Fix conditional check in bandwidth
 calculation.

David reports that at drivers/usb/host/xhci.c:2257:

static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
    return (ep_type == ISOC_IN_EP || ep_type != INT_IN_EP);
}

The static analyser cppcheck says

[linux-3.7-rc2/drivers/usb/host/xhci.c:2257]: (style) Redundant condition: If ep_type == 5, the comparison ep_type != 7 is always true.

Maybe the original programmer intention was something like

static bool xhci_is_sync_in_ep(unsigned int ep_type)
{
    return (ep_type == ISOC_IN_EP || ep_type == INT_IN_EP);
}

Fix this.

This patch should be backported to stable kernels as old as 3.2, that
contain the commit 2b69899934c63b7b9432568584fb4c4a2924f40c "xhci: USB
3.0 BW checking."

Subject: [PATCH 1443/3298] xHCI: Fix TD Size calculation on 1.0 hosts.

The xHCI 1.0 specification made a change to the TD Size field in TRBs.
The value is now the number of packets that remain to be sent in the TD,
not including this TRB.  The TD Size value for the last TRB in a TD must
always be zero.

The xHCI function xhci_v1_0_td_remainder() attempts to calculate this,
but it gets it wrong.  First, it erroneously reuses the old
xhci_td_remainder function, which will right shift the value by 10.  The
xHCI 1.0 spec as of June 2011 says nothing about right shifting by 10.
Second, it does not set the TD size for the last TRB in a TD to zero.

Third, it uses roundup instead of DIV_ROUND_UP.  The total packet count
is supposed to be the total number of bytes in this TD, divided by the
max packet size, rounded up.  DIV_ROUND_UP is the right function to use
in that case.

With the old code, a TD on an endpoint with max packet size 1024 would
be set up like so:
TRB 1, TRB length = 600 bytes, TD size = 0
TRB 1, TRB length = 200 bytes, TD size = 0
TRB 1, TRB length = 100 bytes, TD size = 0

With the new code, the TD would be set up like this:
TRB 1, TRB length = 600 bytes, TD size = 1
TRB 1, TRB length = 200 bytes, TD size = 1
TRB 1, TRB length = 100 bytes, TD size = 0

This commit should be backported to kernels as old as 3.0, that contain
the commit 4da6e6f247a2601ab9f1e63424e4d944ed4124f3 "xhci 1.0: Update TD
size field format."

Subject: [PATCH 1444/3298] xhci: fix null-pointer dereference when destroying
 half-built segment rings

xhci_alloc_segments_for_ring() builds a list of xhci_segments and links
the tail to head at the end (forming a ring). When it bails out for OOM
reasons half-way through, it tries to destroy its half-built list with
xhci_free_segments_for_ring(), even though it is not a ring yet. This
causes a null-pointer dereference upon hitting the last element.

Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes
the output parameters to be valid upon this kind of OOM failure, and
calls xhci_ring_free() on them. Since the (incomplete) list/ring should
already be destroyed in that case, this would lead to a use after free.

This patch fixes those issues by having xhci_alloc_segments_for_ring()
destroy its half-built, non-circular list manually and destroying the
invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree().

This patch should be backported to kernels as old as 2.6.31, that
contains the commit 0ebbab37422315a5d0cb29792271085bafdf38c0 "USB: xhci:
Ring allocation and initialization."

A separate patch will need to be developed for kernels older than 3.4,
since the ring allocation code was refactored in that kernel.

Subject: [PATCH 1445/3298] xhci: Extend Fresco Logic MSI quirk.

Ali reports that plugging a device into the Fresco Logic xHCI host with
PCI device ID 1400 produces an IRQ error:

 do_IRQ: 3.176 No irq handler for vector (irq -1)

Other early Fresco Logic host revisions don't support MSI, even though
their PCI config space claims they do.  Extend the quirk to disabling
MSI to this chipset revision.  Also enable the short transfer quirk,
since it's likely this revision also has that quirk, and it should be
harmless to enable.

Subject: [PATCH 1448/3298] ARM: OMAP4: TWL: mux sys_drm_msecure as output for
 PMIC

On OMAP4 boards using the TWL6030 PMIC, the sys_drm_msecure is
connected to the MSECURE input of the TWL6030 PMIC.  This signal
controls the secure-mode operation of the PMIC.  If its not mux'd
correctly, some functionality of the PMIC will not be accessible since
the PMIC will be in secure mode.

For example, if the TWL RTC is in secure mode, most of its registers
are read-only, meaning (re)programming the RTC (e.g. for wakeup from
suspend) will fail.

To fix, ensure the signal is properly mux'd as output when TWL is
intialized.

This fix is required when using recent versions of u-boot (>= v2012.04.01)
since u-boot is no longer setting the default mux for this pin.

Subject: [PATCH 1449/3298] ARM: boot: Fix usage of kecho

Since commit edc88ceb0 (ARM: be really quiet when building with 'make -s') the
following output is generated when building a kernel for ARM:

echo '  Kernel: arch/arm/boot/Image is ready'
  Kernel: arch/arm/boot/Image is ready
  Building modules, stage 2.
echo '  Kernel: arch/arm/boot/zImage is ready'
  Kernel: arch/arm/boot/zImage is ready

As per Documentation/kbuild/makefiles.txt the correct way of using kecho is
'@$(kecho)'.

Make this change so no more unwanted 'echo' messages are displayed.

QEMU first retrieves the supported features via KVM_GET_SUPPORTED_CPUID
and then sets them later. So guest's X86_FEATURE_XSAVE should be masked
out on hosts without X86_FEATURE_XSAVE, making kvm_set_cr4 with
X86_CR4_OSXSAVE fail. Userspaces that allow specifying guest cpuid with
X86_FEATURE_XSAVE even on hosts that do not support it, might be
susceptible to this attack from inside the guest as well.

Allow setting X86_CR4_OSXSAVE bit only if host has XSAVE support.

When walking page tables we need to make sure that everything

Otherwise we might calculate e.g. a pud pointer which is not
within a pud and dereference it.
So check against TASK_SIZE (which is the ASCE limit) before
walking page tables.

Subject: [PATCH 1456/3298] s390/mm: have 16 byte aligned struct pages

Select HAVE_ALIGNED_STRUCT_PAGE on s390, so that the slub allocator can make
use of compare and swap double for lockless updates. This increases the size
of struct page to 64 bytes (instead of 56 bytes), however the performance gain
justifies the increased size:

- now excactly four struct pages fit into a single cache line; the
  case that accessing a struct page causes two cache line loads
  does not exist anymore.
- calculating the offset of a struct page within the memmap array
  is only a simple shift instead of a more expensive multiplication.

Subject: [PATCH 1457/3298] drm/i915: do not ignore eDP bpc settings from vbt

There are laptops out there that need the eDP bpc from VBT. This is
effectively a revert of

commit 4344b813f105a19f793f1fd93ad775b784648b95
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Aug 10 11:10:20 2012 +0200

    drm/i915: ignore eDP bpc settings from vbt

but putting the VBT check after the EDID check to see them both in dmesg if
this clamps more than the EDID. We have enough history with bpc clamping to
warrant the extra debug info.

Subject: [PATCH 1458/3298] [SCSI] isci: copy fis 0x34 response into proper
 buffer

SATA MICROCODE DOWNALOAD fails on isci driver. After receiving Register
Device to Host (FIS 0x34) frame Initiator resets phy.
In the frame handler routine response (FIS 0x34) was copied into wrong
buffer and upper layer did not receive any answer which resulted in
timeout and reset.
This patch corrects this bug.

Subject: [PATCH 1459/3298] MIPS: Malta: Fix interupt number of CBUS UART.

The CBUS UART's interrupt number was wrong conflicting with the interrupt
being tied to the Intel PIIX4.  Since the PIIX4's interrupt is registered
before the CBUS UART which is not being used on most systems this would
not be noticed.

Attempts to open the ttyS2 CBUS UART would result in:

genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade)
serial_link_irq_chain: request failed: -16 for irq: 18

Qemu was written to match the kernel so will need to be fixed also.

Commit f79b2d0f (USB: keyspan: fix NULL-pointer dereferences and

offsets when mapping serial port private data.  This results in
in a GPF when the port is opened.

Martin Steigerwald reported that this change caused a hard lockup when
using USB if threadirqs are enabled.  Thomas pointed out that this patch
is incorrect, and can cause problems.  So revert it to get the
previously working functionality back.

Subject: [PATCH 1467/3298] clocksource: clean up parse_pmtmr()

I changed the strict_strtoul() to kstrtouint().  That has the check
for UINT_MAX built in to it so the ifdefs can be removed.  Also
I changed a printk() to pr_info().

Subject: [PATCH 1468/3298] time/jiffies: Make clocksource_jiffies static

Commit f1b8274 ("clocksource: Cleanup clocksource selection") removed all
external references to clocksource_jiffies so there is no need to have the
symbol globally visible.

Fixes the following sparse warning:
  CHECK   kernel/time/jiffies.c kernel/time/jiffies.c:61:20: warning: symbol 'clocksource_jiffies' was not declared. Should it be static?

Subject: [PATCH 1475/3298] staging: comedi: addi_apci_3501: remove
 i_APCI3501_ConfigDigitalOutput()

This function is the digital output subdevice 'insn_config' operation.
It does not follow the comedi API and the digital output channels on
this board are not configurable. Just remove this broken function.

Subject: [PATCH 1477/3298] staging: comedi: addi_apci_3501: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single output channel or all the channels and the 'insn_bits' function to
read the state of either a single channel or all the channels.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1478/3298] staging: comedi: addi_apci_3xxx: fix digital input
 'insn_bits' function

This driver does not follow the comedi API. The digital input 'insn_bits'
function is supposed to return the status of all the input channels in
data[1]. Currently this function is returning the status in data[0]. It
is also unnecessarily testing the size of the return buffer.

Fix the function so it works like the comedi core expects. The core can
then use the function to emulate the 'insn_read' function for individual
channels. This allows removing the i_APCI3XXX_InsnReadDigitalInput()
function.

Subject: [PATCH 1479/3298] staging: comedi: addi_apci_3xxx: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1481/3298] staging: comedi: addi_apci_3200: fix digital input
 'insn_bits' function

This driver does not follow the comedi API. The digital input 'insn_bits'
function is supposed to return the status of all the input channels in
data[1]. Currently this function uses the data[0] parameter to determine
if a single channel or all thei nput channels are being read. The status
is then being returned in data[0].

Fix the function so it works like the comedi core expects. The core can
then use the function to emulate the 'insn_read' function for individual
channels.

Subject: [PATCH 1482/3298] staging: comedi: addi_apci_3200: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single or all the output channels. And it uses the 'insn_bits' function
to read either a single or all the output channel states.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1485/3298] staging: comedi: addi_apci_3120: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single or all the output channels. And it uses the 'insn_bits' function
to read either a single or all the output channel states.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

function of the digital output subdevice to enable/disable writing to
the eeprom on the board. Remove this function.

 i_APCI2200_ConfigDigitalOutput()

The digital outputs of the board supported by this driver are not
configurable. This driver abuses the comedi API and uses the 'insn_config'
function of the digital output subdevice to enable/disable writing to
the eeprom on the board. Remove this function.

Subject: [PATCH 1490/3298] staging: comedi: addi_apci_2032: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single or all the output channels. And it uses the 'insn_bits' function
to read either a single or all the output channel states.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1491/3298] staging: comedi: addi_apci_2016: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single or all the output channels. And it uses the 'insn_bits' function
to read either a single or all the output channel states.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1492/3298] staging: comedi: addi_apci_2016: remove
 i_APCI2016_ConfigDigitalOutput()

The digital outputs of the board supported by this driver are not
configurable. This driver abuses the comedi API and uses the 'insn_config'
function of the digital output subdevice to enable/disable writing to
the eeprom on the board. Remove this function.

Subject: [PATCH 1493/3298] staging: comedi: addi_apci_1564: fix digital input
 'insn_bits' function

This driver does not follow the comedi API. The digital input 'insn_bits'
function is supposed to return the status of all the input channels in
data[1]. Currently this function returns the status in data[0].

Fix the function so it works like the comedi core expects. The core can
then use the function to emulate the 'insn_read' function for individual
channels.

Subject: [PATCH 1494/3298] staging: comedi: addi_apci_1564: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single or all the output channels. And it uses the 'insn_bits' function
to read either a single or all the output channel states.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1495/3298] staging: comedi: addi_apci_1516: fix digital input
 'insn_bits' function

This driver does not follow the comedi API. The digital input 'insn_bits'
function is supposed to return the status of all the input channels in
data[1]. Currently this function returns the status in data[0].

Fix the function so it works like the comedi core expects. The core can
then use the function to emulate the 'insn_read' function for individual
channels.

Subject: [PATCH 1496/3298] staging: comedi: addi_apci_1516: fix digital output
 'insn_bits' function

This driver does not follow the comedi API. The digital output 'insn_bits'
function is passed a mask value in data[0] indicating which output bits in
data[1] are changing. The function is then supposed to update the outputs
accordingly and then return the current state of the outputs in data[1].

Currently this driver uses the 'insn_write' function to update either a
single or all the output channels. And it uses the 'insn_bits' function
to read either a single or all the output channel states.

Fix the 'insn_bits' function so it works like the comedi core expects. The
core can then use the function to emulate the 'insn_read' and 'insn_write'
functions for individual channels.

Subject: [PATCH 1497/3298] staging: comedi: addi_apci_1516: remove
 i_APCI1516_ConfigDigitalOutput()

The digital outputs of the board supported by this driver are not
configurable. This driver abuses the comedi API and uses the 'insn_config'
function of the digital output subdevice to enable/disable writing to
the eeprom on the board. Remove this function.

Subject: [PATCH 1498/3298] staging: comedi: addi_apci_1500: fix digital input
 'insn_bits' function

This driver does not follow the comedi API. The digital input 'insn_bits'
function is supposed to return the status of all the input channels in
data[1]. Currently this function returns the status in data[0].

Fix the function so it works like the comedi core expects.

The 'insn_read' and 'insn_Write' functions for the digital input subdevice
cannot be removed yet. This driver is again abusing the API and uses these
functions to initialize the board and start/stop "events" generated by the
board. These will be addressed later.

Subject: [PATCH 1502/3298] x86, cacheinfo: Base cache sharing info on CPUID
 0x8000001d on AMD

The patch is based on a patch submitted by Hans Rosenfeld.
See http://marc.info/?l=linux-kernel&m=133908777200931

Note that  CPUID Fn8000_001D_EAX slightly differs to Intel's CPUID function 4.

Bits 14-25 contain NumSharingCache. Actual number of cores sharing
           this cache. SW to add value of one to get result.

The corresponding bits on Intel are defined as "maximum number of threads
sharing this cache" (with a "plus 1" encoding).

Thus a different method to determine which cores are sharing a cache
level has to be used.

Return codes of IPA_CMD_QIPASSIST are not checked, especially the ones which
indicate that the command is not supported. As a result, the device driver
would not enable all available features on older card generations.
This patch adds proper checking and sets the bare minimum in the supported
functions flags to avoid follow-on errors.

Subject: [PATCH 1505/3298] qeth: set new mac even if old mac is gone

If the set_mac_address() function of qeth is invoked, qeth deletes
the old mac address first on OSA. Only if deletion returns
successfully the new mac address is set on OSA. Deletion may return
with a return value "MAC not found on OSA". In this case qeth
should continue setting the new mac address.

When the OSA cable is pulled, OSA forgets any set mac address. If
the OSA network interface acts as a slave to a bonding master
interface, bonding can invoke the set_mac_address function for
failover purposes and depends on successful setting of the new mac
address even though the old mac address could no longer be deleted.

Subject: [PATCH 1506/3298] net: cdc_ncm: add Huawei devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A number of Huawei 3G and LTE modems implement a CDC NCM function,
including the necessary functional descriptors, but using a non
standard interface layout and class/subclass/protocol codes.

These devices can be handled by this driver with only a minor
change to the probing logic, allowing a single combined control
and data interface.  This works because the devices
- include a CDC Union descriptor labelling the combined
  interface as both master and slave, and
- have an alternate setting #1 for the bulk endpoints on the
  combined interface.

The 3G/LTE network connection is managed by vendor specific AT
commands on a serial function in the same composite device.
Handling the managment function is out of the scope of this
driver.  It will be handled by an appropriate USB serial
driver.

Subject: [PATCH 1507/3298] tcp: tcp_replace_ts_recent() should not be called
 from tcp_validate_incoming()

We added support for RFC 5961 in latest kernels but TCP fails
to perform exhaustive check of ACK sequence.

We can update our view of peer tsval from a frame that is
later discarded by tcp_ack()

This makes timestamps enabled sessions vulnerable to injection of
a high tsval : peers start an ACK storm, since the victim
sends a dupack each time it receives an ACK from the other peer.

As tcp_validate_incoming() is called before tcp_ack(), we should
not peform tcp_replace_ts_recent() from it, and let callers do it
at the right time.

 size being 10 bytes too large

This change fixes an issue I found where VXLAN frames were fragmented when
they were up to the VXLAN MTU size.  I root caused the issue to the fact that
the headroom was 4 + 20 + 8 + 8.  This math doesn't appear to be correct
because we are not inserting a VLAN header, but instead a 2nd Ethernet header.
As such the math for the overhead should be 20 + 8 + 8 + 14 to account for the
extra headers that are inserted for VXLAN.

Subject: [PATCH 1511/3298] staging: comedi: addi-data: use auto_attach instead
 of attach_pci

Change the addi-data drivers that use the "common" code so they
attach using the generic 'auto_attach' method instead the pci
specific 'attach_pci' method. The 'attach_pci' is deprecated and
is going to be removed.

Subject: [PATCH 1513/3298] staging: comedi: addi_common.c: fix the test for
 the PCI bars

Commit: 0fcdafb83b9b4e5c48410b3ca91b1f237ad60dbc
staging: comedi: addi-data: cleanup reading of the PCI bars

Changed this test before reading the PCI bars:

	if ((this_board->pc_EepromChip == NULL)
		|| (strcmp(this_board->pc_EepromChip, ADDIDATA_9054) != 0)) {

to this:

	if (!this_board->pc_EepromChip ||
	    !strcmp(this_board->pc_EepromChip, ADDIDATA_9054)) {

I just noticed that the strcmp test is wrong.

This fixes the test and adds a comment for it.

This error "broke" the addi-data drivers but they are broken anyway
since they don't follow the comedi core API.

The addi_apci_1032 driver has been converted to follow the comedi core
API. This error effects that driver since the iobase for it should be
found in PCI bar 1 not 2. This fixes that also.

 in usbduxfastsub_ai_Irq()

The variable 'p' is initialized but never used otherwise, so
remove the unused variable.

Subject: [PATCH 1516/3298] staging: comedi: addi_apci_1032: check shared
 interrupt

In the interrupt service routine, check the device is asserting the
shared interrupt line and check that interrupts have been enabled.

When attaching the device, disable interrupts before setting up the
interrupt handler to avoid handling spurious interrupts before the
device is ready.

+TODOs
+-----
+1. Implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR
+   - I/O is handled asynchronously which presents some issues when error
+     conditions occur.
+2. Implement _robust_ console on top of this. The existing prototype console
+   driver is not ready for the big leagues yet.
+3. Expose means of controlling attach/detach of peers via sysfs. Include
+   GUID-to-port matching/whitelist/blacklist.
+
+-- Issues with firewire stack --
+1. This driver uses the same unregistered vendor id that the firewire core does
+     (0xd00d1e). Perhaps this could be exposed as a define in
+     firewire-constants.h?
+2. MAX_ASYNC_PAYLOAD needs to be publicly exposed by core/ohci
+   - otherwise how will this driver know the max size of address window to
+     open for one packet write?
+3. Maybe device_max_receive() and link_speed_to_max_payload() should be
+     taken up by the firewire core?
+4. To avoid dropping rx data while still limiting the maximum buffering,
+     the size of the AR context must be known. How to expose this to drivers?
+5. Explore if bigger AR context will reduce RCODE_BUSY responses
+   (or auto-grow to certain max size -- but this would require major surgery
+    as the current AR is contiguously mapped)
+
+-- Issues with TTY core --
+  1. Hack for alternate device name scheme
+     - because udev no longer allows device renaming, devices should have
+       their proper names on creation. This is an issue for creating the
+       fwloop<n> device with the fwtty<n> devices because although duplicating
+       roughly the same operations as tty_port_register_device() isn't difficult,
+       access to the tty_class & tty_fops is restricted in scope.
+
+       This is currently being worked around in create_loop_device() by
+       extracting the tty_class ptr and tty_fops ptr from the previously created
+       tty devices. Perhaps an add'l api can be added -- eg.,
+       tty_{port_}register_named_device().

+/**
+ * The design basis for the DMA FIFO is to provide an output side that
+ * complies with the streaming DMA API design that can be DMA'd from directly
+ * (without additional copying), coupled with an input side that maintains a
+ * logically consistent 'apparent' size (ie, bytes in + bytes avail is static
+ * for the lifetime of the FIFO).
+ *
+ * DMA output transactions originate on a cache line boundary and can be
+ * variably-sized. DMA output transactions can be retired out-of-order but
+ * the FIFO will only advance the output in the original input sequence.
+ * This means the FIFO will eventually stall if a transaction is never retired.
+ *
+ * Chunking the output side into cache line multiples means that some FIFO
+ * memory is unused. For example, if all the avail input has been pended out,
+ * then the in and out markers are re-aligned to the next cache line.
+ * The maximum possible waste is
+ *     (cache line alignment - 1) * (max outstanding dma transactions)
+ * This potential waste requires additional hidden capacity within the FIFO
+ * to be able to accept input while the 'apparent' size has not been reached.
+ *
+ * Additional cache lines (ie, guard area) are used to minimize DMA
+ * fragmentation when wrapping at the end of the FIFO. Input is allowed into the
+ * guard area, but the in and out FIFO markers are wrapped when DMA is pended.

+ *   'serial' unit specifier id
+ * - adding a unit directory to the config ROM(s) for a 'serial' unit
+ *
+ * The firewire core registers unit devices by enumerating unit directories
+ * of a node's config ROM after reading the config ROM when a new node is
+ * added to the bus topology after a bus reset.
+ *
+ * The practical implications of this are:
+ * - this probe is called for both local and remote nodes that have a 'serial'
+ *   unit directory in their config ROM (that matches the specifiers in
+ *   fwserial_id_table).
+ * - no specific order is enforced for local vs. remote unit devices
+ *
+ * This unit driver copes with the lack of specific order in the same way the
+ * firewire net driver does -- each probe, for either a local or remote unit
+ * device, is treated as a 'peer' (has a struct fwtty_peer instance) and the
+ * first peer created for a given fw_card (tracked by the global fwserial_list)
+ * creates the underlying TTYs (aggregated in a fw_serial instance).
+ *
+ * NB: an early attempt to differentiate local & remote unit devices by creating
+ *     peers only for remote units and fw_serial instances (with their
+ *     associated TTY devices) only for local units was discarded. Managing
+ *     the peer lifetimes on device removal proved too complicated.
+ *
+ * fwserial_probe/fwserial_remove are effectively serialized by the
+ * fwserial_list_mutex. This is necessary because the addition of the first peer
+ * for a given fw_card will trigger the creation of the fw_serial for that
+ * fw_card, which must not simultaneously contend with the removal of the

Subject: [PATCH 1518/3298] mac80211: deinitialize ibss-internals after
 emptiness check

The check whether the IBSS is active and can be removed should be
performed before deinitializing the fields used for the check/search.
Otherwise, the configured BSS will not be found and removed properly.

To make it more clear for the future, rename sdata->u.ibss to the
local pointer ifibss which is used within the checks.

This behaviour was introduced by
f3209bea110cade12e2b133da8b8499689cb0e2e
("mac80211: fix IBSS teardown race")

Subject: [PATCH 1519/3298] Staging: bcm: Add two products and remove an
 existing product.

This patch adds two new products and modifies
the device id table to include them. In addition,
product of 0xbccd - BCM_USB_PRODUCT_ID_SM250 is
removed because Beceem, ZTE, Sprint use this id
for block devices.

bReAllocSkb == FALSE is when data is not fed to user land.

Free and relocate skbuff.

Where data is not sent return = FALSE from RXbBulkInProcessData.

This appears to reduce false errors when a reused skbuff has old data.

Subject: [PATCH 1543/3298] tracing,x86: Add a TSC trace_clock

In order to promote interoperability between userspace tracers and ftrace,
add a trace_clock that reports raw TSC values which will then be recorded
in the ring buffer. Userspace tracers that also record TSCs are then on
exactly the same time base as the kernel and events can be unambiguously
interlaced.

Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large
timestamp values.

v2:
Move arch-specific bits out of generic code.
v3:
Rename "x86-tsc", cleanups
v7:
Generic arch bits in Kbuild.

From 8be0709f10e3dd5d7d07933ad61a9f18c4b93ca5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1544/3298] tracing: Format non-nanosec times from tsc clock
 without a decimal point.

With the addition of the "tsc" clock, formatting timestamps to look like
fractional seconds is misleading. Mark clocks as either in nanoseconds or
not, and format non-nanosecond timestamps as decimal integers.

Tested:
$ cd /sys/kernel/debug/tracing/
$ cat trace_clock
[local] global tsc
$ echo sched_switch > set_event
$ echo 1 > tracing_on ; sleep 0.0005 ; echo 0 > tracing_on

v2:
Move arch-specific bits out of generic code.
v4:
Fix x86_32 build due to 64-bit division.

Subject: [PATCH 1545/3298] tracing: Show raw time stamp on stats per cpu using
 counter or tsc mode for trace_clock

Show raw time stamp values for stats per cpu if you choose counter or tsc mode
for trace_clock. Although a unit of tracing time stamp is nsec in local or global mode,
the units in counter and TSC mode are tracing counter and cycles respectively.

Subject: [PATCH 1546/3298] tracing: Kill unused and puzzled sample code in
 ftrace.h

When doing per-cpu helper optimizing work, find that this code is so puzzled.
1. It's mark as comment text, maybe a sample function for guidelines
   or a todo work.
2. But, this sample code is odd where struct perf_trace_buf is nonexistent.
   commit ce71b9 delete struct perf_trace_buf definition.

   Author: Frederic Weisbecker <fweisbec@gmail.com>
   Date:   Sun Nov 22 05:26:55 2009 +0100

   tracing: Use the perf recursion protection from trace event

Is it necessary to keep there?
just compile test.

Subject: [PATCH 1560/3298] staging: vt6656: 64bit fixes: vCommandTimerWait
 change calculation of timer.

The timer appears to run too fast/race on 64 bit systems.

Using msecs_to_jiffies seems to cause a deadlock on 64 bit.

A calculation of (MSecond * HZ) / 1000 appears to run satisfactory.

Change BSSIDInfoCount to u32.

After this patch the driver can be successfully connect on little endian 64/32 bit systems.

From 3e779fc9491f717379343bdc15c3a20d7ff7d77f Mon Sep 17 00:00:00 2001
From: Aaro Koskinen <aaro.koskinen@iki.fi>
Date: Sun, 4 Nov 2012 21:14:42 +0200
Subject: [PATCH 1562/3298] staging: xgifb: XGI_GetLcdPtr: add separate table
 for VB_SIS301LV/VB_SIS302LV

Add a separate data table for VB_SIS301LV/VB_SIS302LV to avoid branching
and to make further cleanups easier.

Subject: [PATCH 1588/3298] Revert "Staging: Android alarm: IOCTL command
 encoding fix"

Commit 6bd4a5d96c08dc2380f8053b1bd4f879f55cd3c9 changed the
ANDROID_ALARM_GET_TIME ioctls from IOW to IOR.  While technically
correct, the _IOC_DIR bits are ignored by alarm_ioctl, so the
commit breaks a userspace ABI used by all existing Android devices
for a purely cosmetic reason.  Revert it.

Subject: [PATCH 1602/3298] staging: line6: fix quoted string across lines in
 midibuf.c

Checkpatch warns when quoted strings are split across lines.  The
rationale is that quoted strings should be left on a single line so that
grep works.  (The 80 character line limit does not apply to quoted
strings.)

There are a few instances of 80+ character lines in playback.c.  Two
instances are just because of a useless comment "this is somewhat
paranoid", so drop the comment.  Other instances are straightforward
line wrapping.

 in toneport.c

The LED value is an int, so replace strict_strtol() with kstrtoint().
It's safe to pass in the actual variable instead of a local temporary
because strto*() doesn't write to the result unless the function returns
success.

Subject: [PATCH 1609/3298] MAINTAINERS: i2c: 7 years, this is it

I have been maintaining the i2c subsystem for 7 years now, it's about
time to let someone else take over. Just before I leave, I would like
to thank several individuals who made this possible at all:

* Greg Kroah-Hartman, for his faith in my potential subsystem
  maintainer skills. Greg, I hope I met your expectations.
* Late David Brownell, for helping me convert the i2c subsystem to the
  standard device driver model. Rest in peace David, we're missing you.
* Ben Dooks, for stepping in when I asked for someone to take care of
  the huge flow of new i2c adapter drivers for embedded systems.
* Wolfram Sang, for joining the crew when it became clear that there
  was more review work than Ben and myself could deal with.

I hope I did not forget anyone, please forgive me if I did.

Another big thank is due to Wolfram again, who quickly proposed to
take over as the main i2c subsystem maintainer. This will allow for a
smooth and fast transition.

Note that I will keep maintaining all I2C/SMBus controller drivers for
PC systems as well as a few others. I am hereby updating MAINTAINERS
accordingly. I'll also keep maintaining user-space i2c-tools.

Subject: [PATCH 1611/3298] rcu: Fix batch-limit size problem

Commit 29c00b4a1d9e27 (rcu: Add event-tracing for RCU callback
invocation) added a regression in rcu_do_batch()

Under stress, RCU is supposed to allow to process all items in queue,
instead of a batch of 10 items (blimit), but an integer overflow makes
the effective limit being 1.  So, unless there is frequent idle periods
(during which RCU ignores batch limits), RCU can be forced into a
state where it cannot keep up with the callback-generation rate,
eventually resulting in OOM.

This commit therefore converts a few variables in rcu_do_batch() from
int to long to fix this problem, along with the module parameters
controlling the batch limits.

Subject: [PATCH 1614/3298] rcu: Clarify memory-ordering properties of
 grace-period primitives

This commit explicitly states the memory-ordering properties of the
RCU grace-period primitives.  Although these properties were in some
sense implied by the fundmental property of RCU ("a grace period must
wait for all pre-existing RCU read-side critical sections to complete"),
stating it explicitly will be a great labor-saving device.

Subject: [PATCH 1623/3298] staging: et131x: Avoid unnecessary calculations in
 for loop

In et131x_rx_dma_memory_alloc(), we loop over fbr_entries - the values of
fbr_align and fbr_chunksize calculated in the loop do not depend on the
loop counter and are the same for all loop iterations.

Take the calculations of these values out of the loop, as we only
need to calculate them once per loop, not once per loop iteration.

 alignment code

"The cpu return address and the DMA bus master address are both
guaranteed to be aligned to the smallest PAGE_SIZE order which
is greater than or equal to the requested size."

There are several places in the et131x.c code where these addresses are
aligned to a 4k boundary after a call to dma_alloc_coherent(),
needlessly.

Remove these alignment offset calculations, and the
et131x_align_allocated_memory() call which is only used for 4k
alignments.

Subject: [PATCH 1633/3298] staging: omap-thermal: remove freq_clip table

The API exposed by cpu cooling does not need any freq clip
table anymore. Now the cpu cooling device is smart enough
to build its own table.

For this reason, this patch removes all the code that is
generating a freq clip table and also removes all references
in data structures regarding freq clip table.

Subject: [PATCH 1635/3298] staging: omap-thermal: fix context restore function

In the context restore function, if the context is lost or
not is being checked by the contents of the counter register.
But this is logic hold good as long as counter reset value is
zero, if the reset value is non-zero then above logic doesn't
hold good. Hence removed checking of the register value and
restoring the context.

Subject: [PATCH 1637/3298] staging: comedi: addi_apci_1516: merge in
 addi_apci_2016 driver

The low-level hardware support code for these drivers, hwdrv_apci1516.c
and hwdrv_apci2016.c, is identical. Both of these boards are 16 channel
dio boards. The 1516 board has 8 input/8 output channels and the 2016
has 16 output channels.

To ease maintainability, merge the boardinfo and pci device information
from the addi_apci_2016 driver into the addi_apci_1516 driver and modify
the Kconfig and Makefile appropriately.

This allows deleting the addi_apci_2016.c and hwdrv_apci2016.c files.

Subject: [PATCH 1638/3298] staging: comedi: addi_apci_1516: add support for
 apci1016 board

The apci1016 board can also be supported by this driver. This board is
also a 16 channel dio board with 16 input channels. The apci1016 does
not have the watchdog timer feature of the apci1516 and apci2016.

Subject: [PATCH 1640/3298] staging: comedi: addi_apci_1516: define the
 watchdog control register

Add defines for the bits in the watchdog control register and use
them to remove the "magic" numbers.

Subject: [PATCH 1641/3298] staging: comedi: addi_apci_1516: separate from
 addi_common.c

This driver is for simple 16 channel dio boards. Using the addi-data
"common" code introduces a lot of bloat.

Copy the code in addi_common.c to this driver and remove the #include
that caused addi_common.c to be compiled with this driver. This will
allow removing the bloat.

Rename the attach_pci and detach functions so they have namespace
associated with this driver.

Subject: [PATCH 1645/3298] staging: comedi: addi_apci_1516: remove eeprom
 support code

Reading the eeprom on the boards supported by this driver is not
necessary. All the information required is in the boardinfo.

Remove the eeprom support code since it's not really interesting
or useful.

The same low-level reset function is used by all the boards supported

Rename the CamelCase function i_ADDI_Reset() to apci1516_reset().

Subject: [PATCH 1652/3298] staging: comedi: addi_apci_1516: simplify the PCI
 bar reading

The boards supported by this driver have an eeprom attached to a S5920
PCI controller chip. Knowing this information allows simplifying the
code that reads the PCI bars to get the iobase address.

The i_IorangeBase[012], i_PCIEeprom, and pc_EepromChip data in the
boardinfo was only needed to work out the usage of the PCI bars.
This is no longer needed so remove the data.

Subject: [PATCH 1659/3298] staging: comedi: addi_apci_1516: remove use of
 struct addi_private

The only private data this driver has is the iobase address for the
watchdog. Create a local struct to hold this information in dev->private
and remove the need for struct addi_private from the "common" code.

Subject: [PATCH 1660/3298] staging: comedi: addi_apci_1516: remove use of

The only boardinfo needed in this driver only consists of 6 data
values. The "common" addi_board has a lot of unnecessary bloat.

Create a local struct for this drivers boardinfo and remove the
need for struct addi_board in the "common" code.

Subject: [PATCH 1662/3298] staging: comedi: addi_apci_1516: cleanup
 addi_find_boardinfo()

This driver uses the comedi auto_config mechanism to attach to the
PCI board.

This mechanism does not require passing the boardinfo data in the
comedi_driver. Remove it and modify the code to directly access
the boardinfo data instead of messing with the dev->driver->board_name
pointer.

All the boards supported by this driver have the same PCI vendor id.
Remove this extra info from the boardinfo and the test for it.

Rename the function so it has namespace associated with this driver.

Subject: [PATCH 1664/3298] staging: comedi: addi_apci_1516: remove setting of
 s->len_chanlist

This value only has meaning for subdevices that support async commands.
Since this driver does not support async commands on any of its subdevices,
don't bother setting it . The comedi core will detect this and set the
value appropriately.

This value only has meaning for dio subdevices. Don't bother setting
it for the di and do subdevices in this driver.

 s->subdev_flags

The flags SDF_GROUND and SDF_COMMON only have meaning for analog
input/output subdevices. Remove these flags from the digital
input/output and timer subdevices in this driver.

The digital output subdevice does not need the SDF_READABLE flags.
Remove it.

This driver uses the comedi auto_config mechanism to attach to

comedi_to_pci_dev() will always return a valid pcidev. Remove
the unnecessary test.

 i_APCI1516_ConfigWatchdog()

This function is used by the watchdog subdevice to enable/disable and
set the timeout for the watchdog. Rename the CamelCase function to
apci1516_wdog_insn_config.

Currently this function does not follow the comed API. Recode it so
it works like the core expects. data[0] is the configuration id code
(INSN_CONFIG_*) for the configuration instruction. Two instructions
are supported:

INSN_CONFIG_ARM: enables the watchdog and sets the timeout value
INSN_CONFIG_DISARM: disables the watchdog

Subject: [PATCH 1672/3298] staging: comedi: addi_apci_1516: fix
 i_APCI1516_StartStopWriteWatchdog()

This function is used by the watchdog subdevice to "ping" the watchdog.
Rename the CamelCase function to apci1516_wdog_insn_write.

Currently this function does not follow the comed API. INSN_WRITE functions
are supposed to write insn->n values. Also, starting and stopping the
watchdog is handled by the INSN_CONFIG function.

Fix this function so it works like the comedi core expects. Also, since
the watchdog needs to be enabled in order to "ping" it, make sure it is
enabled before writing to it.

Subject: [PATCH 1681/3298] [SCSI] Add a report opcode helper

The REPORT SUPPORTED OPERATION CODES command can be used to query
whether a given opcode is supported by a device. Add a helper function
that allows us to look up commands.

We only issue RSOC if the device reports compliance with SPC-3 or
later. But to err on the side of caution we disable the command for ATA,
FireWire and USB.

Subject: [PATCH 1683/3298] [SCSI] sd: Implement support for WRITE SAME

Implement support for WRITE SAME(10) and WRITE SAME(16) in the SCSI disk
driver.

 - We set the default maximum to 0xFFFF because there are several
   devices out there that only support two-byte block counts even with
   WRITE SAME(16). We only enable transfers bigger than 0xFFFF if the
   device explicitly reports MAXIMUM WRITE SAME LENGTH in the BLOCK
   LIMITS VPD.

 - max_write_same_blocks can be overriden per-device basis in sysfs.

 - The UNMAP discovery heuristics remain unchanged but the discard
   limits are tweaked to match the "real" WRITE SAME commands.

 - In the error handling logic we now distinguish between WRITE SAME
   with and without UNMAP set.

The discovery process heuristics are:

 - If the device reports a SCSI level of SPC-3 or greater we'll issue
   READ SUPPORTED OPERATION CODES to find out whether WRITE SAME(16) is
   supported. If that's the case we will use it.

 - If the device supports the block limits VPD and reports a MAXIMUM
   WRITE SAME LENGTH bigger than 0xFFFF we will use WRITE SAME(16).

 - Otherwise we will use WRITE SAME(10) unless the target LBA is beyond
   0xFFFFFFFF or the block count exceeds 0xFFFF.

 - no_write_same is set for ATA, FireWire and USB.

Subject: [PATCH 1685/3298] i2c: at91: fix SMBus quick command

The driver claims to support SMBus quick command but it was not the
case. This patch fixes this issue. Without it, i2cdetect finds imaginary
devices. And with some IP versions, trying to send 0 byte can cause
issue when writing data to an EEPROM.

Subject: [PATCH 1686/3298] regulator: core: Avoid deadlock when
 regulator_register fails

When regulator_register fails and exits through the scrub path the
regulator_put function was called whilst holding the
regulator_list_mutex, causing deadlock.

This patch adds a private version of the regulator_put function which
can be safely called whilst holding the mutex, replacing the
aforementioned call.

Subject: [PATCH 1687/3298] iwlwifi: fix monitor mode FCS flag

When the firmware is in SNIFFER mode, it leaves
the FCS at the end of frame. Not telling mac80211
means it won't add the right flag to the radiotap
header and that confuses wireshark.

Since mac80211 doesn't have a per-packet flag, set
the HW flag dynamically. This works as the monitor
vif can only be present in the driver by itself.

This fixes a regression introduced by my

Subject: [PATCH 1689/3298] ALSA: usb-audio: Fix mutex deadlock at
 disconnection

The recent change for USB-audio disconnection race fixes introduced a
mutex deadlock again.  There is a circular dependency between
chip->shutdown_rwsem and pcm->open_mutex, depicted like below, when a
device is opened during the disconnection operation:

A. snd_usb_audio_disconnect() ->
     card.c::register_mutex ->
       chip->shutdown_rwsem (write) ->
         snd_card_disconnect() ->
           pcm.c::register_mutex ->
             pcm->open_mutex

B. snd_pcm_open() ->
     pcm->open_mutex ->
       snd_usb_pcm_open() ->
         chip->shutdown_rwsem (read)

Since the chip->shutdown_rwsem protection in the case A is required
only for turning on the chip->shutdown flag and it doesn't have to be
taken for the whole operation, we can reduce its window in
snd_usb_audio_disconnect().

Subject: [PATCH 1690/3298] i2c: omap: ensure writes to dev->buf_len are
 ordered

if we allow compiler reorder our writes, we could
fall into a situation where dev->buf_len is reset
for no apparent reason.

This bug was found with a simple script which would
transfer data to an i2c client from 1 to 1024 bytes
(a simple for loop), when we got to transfer sizes
bigger than the fifo size, dev->buf_len was reset
to zero before we had an oportunity to handle XDR
Interrupt. Because dev->buf_len was zero, we entered
omap_i2c_transmit_data() to transfer zero bytes,
which would mean we would just silently exit
omap_i2c_transmit_data() without actually writing
anything to DATA register. That would cause XDR
IRQ to trigger forever and we would never transfer
the remaining bytes.

After adding the memory barrier, we also drop resetting
dev->buf_len to zero in omap_i2c_xfer_msg() because
both omap_i2c_transmit_data() and omap_i2c_receive_data()
will act until dev->buf_len reaches zero, rendering the
other write in omap_i2c_xfer_msg() redundant.

This patch has been tested with pandaboard for a few
iterations of the script mentioned above.

Subject: [PATCH 1692/3298] doc: Add x86 CPU0 online/offline feature

If CONFIG_BOOTPARAM_HOTPLUG_CPU0 is turned on, CPU0 is hotpluggable. Otherwise,
by default CPU0 is not hotpluggable and kernel parameter cpu0_hotplug enables
CPU0 online/offline feature.

The documentations point out two known CPU0 dependencies. First, resume from
hibernate or suspend always starts from CPU0. So hibernate and suspend are
prevented if CPU0 is offline. Another dependency is PIC interrupts always go
to CPU0.

It's said that some machines may depend on CPU0 to poweroff/reboot. But I
haven't seen such dependency on a few tested machines.

Please let me know if you see any CPU0 dependencies on your machine.

Subject: [PATCH 1697/3298] kernel/cpu.c: Add comment for priority in
 cpu_hotplug_pm_callback

cpu_hotplug_pm_callback should have higher priority than
bsp_pm_callback which depends on cpu_hotplug_pm_callback to disable cpu hotplug
to avoid race during bsp online checking.

This is to hightlight the priorities between the two callbacks in case people
may overlook the order.

Ideally the priorities should be defined in macro/enum instead of fixed values.
To do that, a seperate patchset may be pushed which will touch serveral other
generic files and is out of scope of this patchset.

Add config option for launching GTK browser for the specified command by
default.  Currently only 'report' command is supported.

Adding following line to the perfconfig file will have a same effect of
specifying --gtk option on command line (unless other related options
are not given).

$ cat ~/.perfconfig

Subject: [PATCH 1718/3298] perf tools: Fix attributes for '{}' defined event
 groups

Fixing events attributes for groups defined via '{}'.

Currently 'enable_on_exec' attribute in record command and both
'disabled ' and 'enable_on_exec' attributes in stat command are set
based on the 'group' option. This eliminates proper setup for '{}'
defined groups as they don't set 'group' option.

Making above attributes values based on the 'evsel->leader' as this is
common to both group definition.

Moving perf_evlist__set_leader call within builtin-record ahead
perf_evlist__config_attrs call, because the latter needs possible group
leader links in place.

Subject: [PATCH 1719/3298] perf tools: Fix 'disabled' attribute config for
 record command

Currently the record command sets all events initially as disabled.

There's non conditional perf_evlist__enable call, that enables all
events before we exec tracee program. That actually screws whole
enable_on_exec logic, because the event is enabled before the traced
program got executed.

What we actually want is:

1) For any type of traced program:
  - all independent events and group leaders are disabled
  - all group members are enabled

   Group members are ruled by group leaders. They need to
   be enabled, because the group scheduling relies on that.

2) For traced programs executed by perf:
   - all independent events and group leaders have
     enable_on_exec set
   - we don't specifically enable or disable any event during
     the record command

   Independent events and group leaders are initially disabled
   and get enabled by exec. Group members are ruled by group
   leaders as stated in 1).

3) For traced programs attached by perf (pid/tid):
   - we specifically enable or disable all events during
     the record command

   When attaching events to already running traced we
   enable/disable events specifically, as there's no
   initial traced exec call.

Fixing appropriate perf_event_attr test case to cover this change.

Subject: [PATCH 1720/3298] perf tools: Ensure single disable call per event in
 record comand

It's possible we issue the event disable ioctl multiple times until we
read the final portion of the mmap buffer.

Ensuring just single disable ioctl call for event, because there's no
need to do that more than once.

The modifier sanity is checked later in parse-event object logic.  The
check validates modifier to contain only one instance of any modifier

Subject: [PATCH 1725/3298] perf ui gtk: Implement ui_progress functions

Implement progress update function for GTK2 front end.

Note that since it will be called before gtk main loop so that we should
call gtk event loop handler directly.

Subject: [PATCH 1726/3298] perf ui: Add ui_progress__finish()

Sometimes we need to know when the progress bar should disappear.

Checking curr >= total wasn't enough since there're cases not met that
condition for the last call.

So add a new ->finish callback to identify this explicitly.  Currently
only GTK frontend needs it.

Subject: [PATCH 1729/3298] tools: Honour the O= flag when tool build called
 from a higher Makefile

Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.

To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).

For example, take perf.  This is found in tools/perf/.  Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make.  Dependening on where
we run the build from, we see:

	make run in dir		$(OUTPUT) dir
	=======================	==================
	linux			~/zebra/tools/perf/
	linux/tools		~/zebra/perf/
	linux/tools/perf	~/zebra/

and if O= is not set, we get:

	make run in dir		$(OUTPUT) dir
	=======================	==================
	linux			linux/tools/perf/
	linux/tools		linux/tools/perf/
	linux/tools/perf	linux/tools/perf/

The output directories are created by the descend function if they don't
already exist.

Subject: [PATCH 1736/3298] usb: spear-ehci/ohci: Use devm_*() routines

This patch frees SPEAr ehci/ohci drivers from tension of freeing resources :)
devm_* derivatives of multiple routines are used while allocating resources,
which would be freed automatically by kernel.

Subject: [PATCH 1737/3298] usb: misc: usbtest: send ISO packets for g_zero

since commit b4036cc (usb: gadget: add
isochronous support to gadget zero), g_zero
has learned about isochronous transfers, which
allows us to use usbtest.ko to exercise
isochronous pipes.

All we need to do to enable that functionality
on usbtest.ko, is set the "iso" to 1 on
struct usbtest_info

Subject: [PATCH 1739/3298] TTY: hvc_console, fix port reference count going to
 zero prematurely

Commit bdb498c20040 "TTY: hvc_console, add tty install" took the port
refcounting out of hvc_open()/hvc_close(), but failed to remove the
kref_put() and tty_kref_put() calls in hvc_hangup() that were there to
remove the extra references that hvc_open() had taken.

The result was that doing a vhangup() when the current terminal was
a hvc_console, then closing the current terminal, would end up calling
destroy_hvc_struct() and making the port disappear entirely.  This
meant that Fedora 17 systems would boot up but then not display the
login prompt on the console, and attempts to open /dev/hvc0 would
give a "No such device" error.

This fixes it by removing the extra kref_put() and tty_kref_put() calls.

commit 611ae8e3f5204f7480b3b405993b3352cfa16662('enable tlb flush range
support for x86') change flush_tlb_mm_range() considerably. After this,
we test whether vmflag equal to VM_HUGETLB and it may be always failed,
because vmflag usually has other flags simultaneously.
Our intention is to check whether this vma is for hughtlb, so correct it
according to this purpose.

Subject: [PATCH 1742/3298] firmware loader: Fix the race FW_STATUS_DONE is
 followed by class_timeout

There is a race as below when calling request_firmware():
CPU1                                   CPU2
write 0 > loading
mutex_lock(&fw_lock)
...
set_bit FW_STATUS_DONE                 class_timeout is coming
                                       set_bit FW_STATUS_ABORT
complete_all &completion
...
mutex_unlock(&fw_lock)

In this time, the bit FW_STATUS_DONE and FW_STATUS_ABORT are set,
and request_firmware() will return failure due to condition in
_request_firmware_load():
	if (!buf->size || test_bit(FW_STATUS_ABORT, &buf->status))
		retval = -ENOENT;

But from the above scenerio, it should be a successful requesting.
So we need judge if the bit FW_STATUS_DONE is already set before
calling fw_load_abort() in timeout function.

As Ming's proposal, we need change the timer into sched_work to
benefit from using &fw_lock mutex also.

Subject: [PATCH 1743/3298] firmware loader: Fix the concurrent
 request_firmware() race for kref_get/put

There is one race that both request_firmware() with the same
firmware name.

The race scenerio is as below:
CPU1                                                  CPU2
request_firmware() -->
_request_firmware_load() return err                   another request_firmware() is coming -->
_request_firmware_cleanup is called -->               _request_firmware_prepare -->
release_firmware --->                                 fw_lookup_and_allocate_buf -->
                                                      spin_lock(&fwc->lock)
...                                                   __fw_lookup_buf() return true
fw_free_buf() will be called -->                      ...
kref_put -->
decrease the refcount to 0
                                                      kref_get(&tmp->ref) ==> it will trigger warning
                                                                              due to refcount == 0
__fw_free_buf() -->
...                                                   spin_unlock(&fwc->lock)
spin_lock(&fwc->lock)
list_del(&buf->list)
spin_unlock(&fwc->lock)
kfree(buf)
                                                      After that, the freed buf will be used.

The key race is decreasing refcount to 0 and list_del is not protected together by
fwc->lock, and it is possible another thread try to get it between refcount==0
and list_del.

Fix it here to protect it together.

 customize(v4) fw search path

This patch introduces one module parameter of 'path' in firmware_class
to support customizing firmware image search path, so that people can
use its own firmware path if the default built-in paths can't meet their
demand[1], and the typical usage is passing the below from kernel command
parameter when 'firmware_class' is built in kernel:

	firmware_class.path=$CUSTOMIZED_PATH

Subject: [PATCH 1748/3298] ACPI / PM: Move routines for adding/removing device
 wakeup notifiers

ACPI routines for adding and removing device wakeup notifiers are
currently defined in a PCI-specific file, but they will be necessary
for non-PCI devices too, so move them to a separate file under
drivers/acpi and rename them to indicate their ACPI origins.

Subject: [PATCH 1749/3298] ACPI / PM: Move device power state selection
 routine to device_pm.c

The ACPI function for choosing device power state is now located
in drivers/acpi/sleep.c, but drivers/acpi/device_pm.c is a more
logical place for it, so move it there.

However, instead of moving the function entirely, move its core only
under a different name and with a different list of arguments, so
that it is more flexible, and leave a wrapper around it in the
original location.

Subject: [PATCH 1750/3298] ACPI / PM: Move runtime remote wakeup setup routine
 to device_pm.c

The ACPI function for setting up devices to do runtime remote
wakeup is now located in drivers/acpi/sleep.c, but
drivers/acpi/device_pm.c is a more logical place for it, so move it
there.

No functional changes should result from this modification.

Subject: [PATCH 1751/3298] ACPI / PM: Split device wakeup management routines

Two device wakeup management routines in device_pm.c and sleep.c,
acpi_pm_device_run_wake() and acpi_pm_device_sleep_wake(), take a
device pointer argument and use it to obtain the ACPI handle of the
corresponding ACPI namespace node.  That handle is then used to get
the address of the struct acpi_device object corresponding to the
struct device passed as the argument.

Unfortunately, that last operation may be costly, because it involves
taking the global ACPI namespace mutex, so it shouldn't be carried
out too often.  However, the callers of those routines usually call
them in a row with acpi_pm_device_sleep_state() which also takes that
mutex for the same reason, so it would be more efficient if they ran
acpi_bus_get_device() themselves to obtain a pointer to the struct
acpi_device object in question and then passed that pointer to the
appropriate PM routines.

To make that possible, split each of the PM routines mentioned above
in two parts, one taking a struct acpi_device pointer argument and
the other implementing the current interface for compatibility.

Additionally, change acpi_pm_device_run_wake() to actually return
an error code if there is an error while setting up runtime remote
wakeup for the device.

Subject: [PATCH 1752/3298] ACPI / PM: Provide device PM functions operating on
 struct acpi_device

If the caller of acpi_bus_set_power() already has a pointer to the
struct acpi_device object corresponding to the device in question, it
doesn't make sense for it to go through acpi_bus_get_device(), which
may be costly, because it involves acquiring the global ACPI
namespace mutex.

For this reason, export the function operating on struct acpi_device
objects used internally by acpi_bus_set_power(), so that it may be
called instead of acpi_bus_set_power() in the above case, and change
its name to acpi_device_set_power().

Additionally, introduce two inline wrappers for checking ACPI PM
capabilities of devices represented by struct acpi_device objects.

Subject: [PATCH 1754/3298] ACPI / PM: Provide ACPI PM callback routines for
 subsystems

Some bus types don't support power management natively, but generally
there may be device nodes in ACPI tables corresponding to the devices
whose bus types they are (under ACPI 5 those bus types may be SPI,
I2C and platform).  If that is the case, standard ACPI power
management may be applied to those devices, although currently the
kernel has no means for that.

For this reason, provide a set of routines that may be used as power
management callbacks for such devices.  This may be done in three
different ways.

 (1) Device drivers handling the devices in question may run
     acpi_dev_pm_attach() in their .probe() routines, which (on
     success) will cause the devices to be added to the general ACPI
     PM domain and ACPI power management will be used for them going
     forward.  Then, acpi_dev_pm_detach() may be used to remove the
     devices from the general ACPI PM domain if ACPI power management
     is not necessary for them any more.

 (2) The devices' subsystems may use acpi_subsys_runtime_suspend(),
     acpi_subsys_runtime_resume(), acpi_subsys_prepare(),
     acpi_subsys_suspend_late(), acpi_subsys_resume_early() as their
     power management callbacks in the same way as the general ACPI
     PM domain does that.

 (3) The devices' drivers may execute acpi_dev_suspend_late(),
     acpi_dev_resume_early(), acpi_dev_runtime_suspend(),
     acpi_dev_runtime_resume() from their power management callbacks
     as appropriate, if that's absolutely necessary, but it is not
     recommended to do that, because such drivers may not work
     without ACPI support as a result.

 acpi_target_system_state()

Commit b87b49cd0efd ("ACPI / PM: Move device PM functions related to sleep
states") declared acpi_target_system_state() for CONFIG_PM_SLEEP whereas
it is only defined for CONFIG_ACPI_SLEEP, resulting in the following link
error:

drivers/built-in.o: In function `acpi_pm_device_sleep_wake':
drivers/acpi/device_pm.c:342: undefined reference to `acpi_target_system_state'
drivers/built-in.o: In function `acpi_dev_suspend_late':

drivers/built-in.o: In function `acpi_pm_device_sleep_state':
drivers/acpi/device_pm.c:221: undefined reference to `acpi_target_system_state'

Define it only for CONFIG_ACPI_SLEEP and fallback to a dummy definition
for other configs.

[rjw: The problem only occurs for exotic .configs in which
 HIBERNATE_CALLBACKS is selected by XEN_SAVE_RESTORE and neither
 SUSPEND nor HIBERNATION is set.]

 spinlock/mutex in struct

Current member names for mutex/spinlock are a little confusing.

Change the
{
	struct mutex lock;
	spinlock_t curr_lock;
}
to
{
	struct mutex mutex;
	spinlock_t lock;
}

So that the code is cleaner and easier to read.

Subject: [PATCH 1758/3298] ACPI / EC: Don't count a SCI interrupt as a false
 one

Currently when advance_transaction() is called in EC interrupt handler,
if there is nothing driver can do with the interrupt, it will be taken
as a false one.

But this is not always true, as there may be a SCI EC interrupt fired
during normal read/write operation, which should not be counted as a
false one. This patch fixes the problem.

Subject: [PATCH 1761/3298] ACPI / processor: prevent cpu from becoming online

Even if acpi_processor_handle_eject() offlines cpu, there is a chance
to online the cpu after that. So the patch closes the window by using
get/put_online_cpus().

Why does the patch change _cpu_up() logic?

The patch cares the race of hot-remove cpu and _cpu_up(). If the patch
does not change it, there is the following race.

hot-remove cpu                         |  _cpu_up()
------------------------------------- ------------------------------------
call acpi_processor_handle_eject()     |
     call cpu_down()                   |
     call get_online_cpus()            |
                                       | call cpu_hotplug_begin() and stop here
     call arch_unregister_cpu()        |
     call acpi_unmap_lsapic()          |
     call put_online_cpus()            |
                                       | start and continue _cpu_up()
     return acpi_processor_remove()    |
continue hot-remove the cpu            |

So _cpu_up() can continue to itself. And hot-remove cpu can also continue
itself. If the patch changes _cpu_up() logic, the race disappears as below:

hot-remove cpu                         | _cpu_up()
-----------------------------------------------------------------------
call acpi_processor_handle_eject()     |
     call cpu_down()                   |
     call get_online_cpus()            |
                                       | call cpu_hotplug_begin() and stop here
     call arch_unregister_cpu()        |
     call acpi_unmap_lsapic()          |
          cpu's cpu_present is set     |
          to false by set_cpu_present()|
     call put_online_cpus()            |
                                       | start _cpu_up()
                                       | check cpu_present() and return -EINVAL
     return acpi_processor_remove()    |
continue hot-remove the cpu            |

Subject: [PATCH 1762/3298] ACPI / x86: Add quirk for "CheckPoint P-20-00" to
 not use bridge _CRS_ info

This is to fix a regression https://bugzilla.kernel.org/show_bug.cgi?id=47981

The CheckPoint P-20-00 works ok before new machines (2008 and later) are
forced to use the bridge _CRS info by default in 2.6.34. Add this quirk
to restore its old way of working: not using bridge _CRS info.

 device is a container, v3

"ACPI0004","PNP0A05" and "PNP0A06" are all defined in array
container_device_ids[], so use it, but not the hard coding style.

Also, introduce a new API is_container_device() to determine if a
device is a container device.

Subject: [PATCH 1764/3298] ACPI: Fix stale pointer access to flags.lockable

During hot-remove, acpi_bus_hot_remove_device() calls ACPI _LCK
method when device->flags.lockable is set. However, this device
pointer is stale since the target acpi_device object has been
already kfree'd by acpi_bus_trim().

The flags.lockable indicates whether or not this ACPI object
implements _LCK method. Fix the stable pointer access by replacing
it with acpi_get_handle() to check if _LCK is implemented.

ACPI devices are glued with physical devices through _ADR object, ACPI

observe _HID/_CID through sysfs interfaces (hid/modalias), but there's
no way for us to check _ADR/_UID from user space.  This patch closes
this gap for ACPI developers and users.

Subject: [PATCH 1772/3298] ACPI: Make seemingly useless check in osl.c more
 understandable

There is a seemingly useless check in drivers/acpi/osl.c added by
commit bc73675 (ACPI: fixes a false alarm from lockdep), which really
is necessary to avoid false positive lockdep complaints.  Document
this and rearrange the code related to it so that it makes fewer
checks.

Subject: [PATCH 1775/3298] driver core / ACPI: Move ACPI support to core
 device and driver types

With ACPI 5 we are starting to see devices that don't natively support
discovery but can be enumerated with the help of the ACPI namespace.
Typically, these devices can be represented in the Linux device driver
model as platform devices or some serial bus devices, like SPI or I2C
devices.

Since we want to re-use existing drivers for those devices, we need a
way for drivers to specify the ACPI IDs of supported devices, so that
they can be matched against device nodes in the ACPI namespace.  To
this end, it is sufficient to add a pointer to an array of supported
ACPI device IDs, that can be provided by the driver, to struct device.

Moreover, things like ACPI power management need to have access to
the ACPI handle of each supported device, because that handle is used
to invoke AML methods associated with the corresponding ACPI device
node.  The ACPI handles of devices are now stored in the archdata
member structure of struct device whose definition depends on the
architecture and includes the ACPI handle only on x86 and ia64. Since
the pointer to an array of supported ACPI IDs is added to struct
device_driver in an architecture-independent way, it is logical to
move the ACPI handle from archdata to struct device itself at the same
time.  This also makes code more straightforward in some places and
follows the example of Device Trees that have a poiter to struct
device_node in there too.

This changeset is based on Mika Westerberg's work.

Introduce function acpi_match_device() allowing callers to match

acpi_driver_match_device() using acpi_match_device() internally and
allowing callers to match a struct device object against an array of
ACPI device IDs provided by a device driver.

Additionally, introduce macro ACPI_PTR() that may be used by device
drivers to escape pointers to data structures whose definitions
depend on CONFIG_ACPI.

Subject: [PATCH 1779/3298] ACPI: Add support for platform bus type

With ACPI 5 it is now possible to enumerate traditional SoC
peripherals, like serial bus controllers and slave devices behind
them.  These devices are typically based on IP-blocks used in many
existing SoC platforms and platform drivers for them may already
be present in the kernel tree.

To make driver "porting" more straightforward, add ACPI support to
the platform bus type.  Instead of writing ACPI "glue" drivers for
the existing platform drivers, register the platform bus type with
ACPI to create platform device objects for the drivers and bind the
corresponding ACPI handles to those platform devices.

This should allow us to reuse the existing platform drivers for the
devices in question with the minimum amount of modifications.

This changeset is based on Mika Westerberg's and Mathias Nyman's
work.

Subject: [PATCH 1780/3298] ACPI / platform: use ACPI device name instead of
 _HID._UID

Using _UID makes the ACPI platform bus code depend on BIOS to get it
right. If it doesn't we fail to create the platform device as the name
should be unique.

The ACPI core already makes a unique name when it first creates the ACPI
device so we can use that same name as the platform device name instead of
trusting that the BIOS sets the _UIDs correctly.

Subject: [PATCH 1781/3298] x86, hotplug: Wake up CPU0 via NMI instead of INIT,
 SIPI, SIPI

Instead of waiting for STARTUP after INITs, BSP will execute the BIOS boot-strap
code which is not a desired behavior for waking up BSP. To avoid the boot-strap
code, wake up CPU0 by NMI instead.

This works to wake up soft offlined CPU0 only. If CPU0 is hard offlined (i.e.
physically hot removed and then hot added), NMI won't wake it up. We'll change
this code in the future to wake up hard offlined CPU0 if real platform and
request are available.

AP is still waken up as before by INIT, SIPI, SIPI sequence.

The first cpu in irq cfg->domain is likely to be CPU 0 and may not be available

first available CPU which is online and in this irq's domain.

Subject: [PATCH 1786/3298] x86, topology: Debug CPU0 hotplug

CONFIG_DEBUG_HOTPLUG_CPU0 is for debugging the CPU0 hotplug feature. The switch
offlines CPU0 as soon as possible and boots userspace up with CPU0 offlined.
User can online CPU0 back after boot time. The default value of the switch is
off.

To debug CPU0 hotplug, you need to enable CPU0 offline/online feature by either
turning on CONFIG_BOOTPARAM_HOTPLUG_CPU0 during compilation or giving
cpu0_hotplug kernel parameter at boot.

It's safe and early place to take down CPU0 after all hotplug notifiers
are installed and SMP is booted.

Please note that some applications or drivers, e.g. some versions of udevd,
during boot time may put CPU0 online again in this CPU0 hotplug debug mode.

In this debug mode, setup_local_APIC() may report a warning on max_loops<=0
when CPU0 is onlined back after boot time. This is because pending interrupt in
IRR can not move to ISR. The warning is not CPU0 specfic and it can happen on
other CPUs as well. It is harmless except the first CPU0 online takes a bit
longer time. And so this debug mode is useful to expose this issue. I'll send
a seperate patch to fix this generic warning issue.

Subject: [PATCH 1787/3298] ACPI: Move device resources interpretation code
 from PNP to ACPI core

Move some code used for parsing ACPI device resources from the PNP
subsystem to the ACPI core, so that other bus types (platform, SPI,
I2C) can use the same routines for parsing resources in a consistent
way, without duplicating code.

Subject: [PATCH 1789/3298] ACPI: Centralized processing of ACPI device
 resources

Currently, whoever wants to use ACPI device resources has to call
acpi_walk_resources() to browse the buffer returned by the _CRS
method for the given device and create filters passed to that
routine to apply to the individual resource items.  This generally
is cumbersome, time-consuming and inefficient.  Moreover, it may
be problematic if resource conflicts need to be resolved, because
the different users of _CRS will need to do that in a consistent
way.  However, if there are resource conflicts, the ACPI core
should be able to resolve them centrally instead of relying on
various users of acpi_walk_resources() to handle them correctly
together.

For this reason, introduce a new function, acpi_dev_get_resources(),
that can be used by subsystems to obtain a list of struct resource
objects corresponding to the ACPI device resources returned by
_CRS and, if necessary, to apply additional preprocessing routine
to the ACPI resources before converting them to the struct resource
format.

Make the ACPI code that creates platform device objects use
acpi_dev_get_resources() for resource processing instead of executing
acpi_walk_resources() twice by itself, which causes it to be much
more straightforward and easier to follow.

In the future, acpi_dev_get_resources() can be extended to meet
the needs of the ACPI PNP subsystem and other users of _CRS in
the kernel.

Subject: [PATCH 1790/3298] Cleanup of invalid ACPI name handling and repair

 Implemented a change/cleanup for the handling of invalid ACPI names.
 Names are now validated and repaired only when
 1) entering a new name into the namespace and
 2) disassembling a named AML opcode. A warning is only displayed in
    debug mode or when the interpreter is in "strict" mode, since some
    working machines do in fact contain invalid ACPI names.

Subject: [PATCH 1791/3298] ACPICA: Fix unmerged utility divergences.

Utility improvements in ACPICA are partial ignored by ACPICA Linux
release.  This will lead to divergences between Linux and ACPICA.
This patch ports the entire "utility" into Linux and makes them
igored in the compilation stage by "ACPI_FUTURE_USAGE".
The following "Utility" files have been ported into the Linux:
  drivers/acpi/uttrack.c
  drivers/acpi/utcache.c
  drivers/acpi/utids.c

This patch will not affect the generated vmlinx binary.
This will decrease 274 lines of 20120913 divergence.diff.

Subject: [PATCH 1792/3298] ACPICA: Fix unmerged debugger divergences.

Debugger improvements in ACPICA are always ignored by ACPICA Linux
release.  This will lead to divergences between Linux and ACPICA.
This patch fixes such unmerged debugger updates.

Following patches are included:
1. Fixed a couple compiler warnings for extra extern
   Wed, 14 Mar 2007 21:12:19 +0000
2. Cleanup for internal Reference Object.
   Wed, 27 Aug 2008 10:11:30 -0700
3. Debugger: Lock method args for multithread command.
   Fri, 24 Apr 2009 12:28:49 -0700
4. Debugger: Add max count argument for Batch command.

5. Add new host interfaces for _OSI support.
   Thu, 5 Aug 2010 14:18:28 -0700
6. Increase debugger buffer size for method return objects.
   Wed, 17 Nov 2010 13:48:30 -0800
7. Debugger: Add command to display status of global handlers.
   Tue, 25 Jan 2011 13:47:58 -0800
8. Debugger: Split large dbcmds.c file.

From 78e25fef2751434f38c7f711ecbf8762f79f7318 Mon Sep 17 00:00:00 2001
From: Lv Zheng <lv.zheng@intel.com>
Date: Wed, 31 Oct 2012 02:25:24 +0000
Subject: [PATCH 1793/3298] ACPICA: Fix divergences of definition conflicts.

There are conflicts in the "acpi_device_id*" definitions between the
Linux and the ACPICA.  The definitions of acpi_device_id* in ACPICA
have been changed to the "acpi_pnp_device_id*".  This patch changes
the corresponding "acpica_device_id*" definitiions in the Linux.

This patch will not affect the generated vmlinx binary.
This will decrease 298 lines of 20120913 divergence.diff.

Subject: [PATCH 1794/3298] ACPICA: Fix AcpiSrc caused divergences.

There are definitions that can been converted into new styles by
the recent AcpiSrc while they remain the old styles in the Linux.
This patch fixes those definitions that will be converted by the
AcpiSrc.

This patch will not affect the generated vmlinux binary.
This will decrease 97 lines of 20120913 divergence.diff.

Subject: [PATCH 1795/3298] ACPICA: Fix indent caused divergences.

New version of "indent" program will generate different outputs that
will lead to the divergences between the Linux and the ACPICA.
This patch fixes such divergences caused by the "indent" program.
The version of the "indent" used for this patch is "GNU indent 2.2.11".

This patch will not affect the generated vmlinux binary.
This will decrease 581 lines of 20120913 divergence.diff.

Subject: [PATCH 1797/3298] ACPICA: Audit/update for ACPICA return macros and
 debug depth counter

1) Ensure that all functions that use the various TRACE macros
   also use the appropriate ACPICA return macros.
2) Ensure that all normal return statements surround the return
   expression (value) with parens.

Add some intelligence to the code that maintains the global

memory address, significantly improving performance.  When running
AcpiExec on the ASLTS test suite, speed improvements of 3X to 5X
are seen, depending on the platform and/or the environment.

Subject: [PATCH 1817/3298] cpufreq / core: Fix printing of governor and driver
 name

Arrays for governer and driver name are of size CPUFREQ_NAME_LEN or 16.
i.e. 15 bytes for name and 1 for trailing '\0'.

When cpufreq driver print these names (for sysfs), it includes '\n' or ' ' in
the fmt string and still passes length as CPUFREQ_NAME_LEN. If the driver or
governor names are using all 15 fields allocated to them, then the trailing '\n'
or ' ' will never be printed. And so commands like:

root@linaro-developer# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver

will print something like:

cpufreq_foodrvroot@linaro-developer#

Fix this by increasing print length by one character.

Subject: [PATCH 1818/3298] cpufreq: Move common part from governors to
 separate file, v2

Multiple cpufreq governers have defined similar get_cpu_idle_time_***()
routines. These routines must be moved to some common place, so that all
governors can use them.

So moving them to cpufreq_governor.c, which seems to be a better place for
keeping these routines.

Subject: [PATCH 1820/3298] cpufreq: fix jiffies/cputime mixup in
 conservative/ondemand governors

The function get_cpu_idle_time_jiffy in both the conservative and
ondemand governors use jiffies_to_usecs to convert a cputime value to
usecs which gives the wrong value on architectures where cputime and
jiffies use different units.  Only matters if NO_HZ is disabled, since
otherwise get_cpu_idle_time_us should already return a valid value, and
get_cpu_idle_time_jiffy isn't actually called.

Subject: [PATCH 1822/3298] cpufreq: governors: remove redundant code

Initially ondemand governor was written and then using its code conservative
governor is written. It used a lot of code from ondemand governor, but copy of
code was created instead of using the same routines from both governors. Which
increased code redundancy, which is difficult to manage.

This patch is an attempt to move common part of both the governors to
cpufreq_governor.c file to come over above mentioned issues.

This shouldn't change anything from functionality point of view.

Subject: [PATCH 1823/3298] cpufreq: Fix sparse warnings by updating
 cputime64_t to u64

There were few sparse warnings due to mismatch of type on function arguments.
Two types were used u64 and cputime64_t. Both are actually u64, so use u64 only.

Today most of cpufreq platform drivers are doing this check in their
target routines. Why not move it to __cpufreq_driver_target()?

Subject: [PATCH 1828/3298] cpuidle / sysfs: change function parameter

The function needs the cpuidle_device which is initially passed to the
caller.

The current code gets the struct device from the struct cpuidle_device,
pass it the cpuidle_add_sysfs function. This function calls
per_cpu(cpuidle_devices, cpu) to get the cpuidle_device.

This patch pass the cpuidle_device instead and simplify the code.

Subject: [PATCH 1830/3298] cpuidle: Quickly notice prediction failure for
 repeat mode

The prediction for future is difficult and when the cpuidle governor prediction
fails and govenor possibly choose the shallower C-state than it should. How to
quickly notice and find the failure becomes important for power saving.

cpuidle menu governor has a method to predict the repeat pattern if there are 8
C-states residency which are continuous and the same or very close, so it will
predict the next C-states residency will keep same residency time.

There is a real case that turbostat utility (tools/power/x86/turbostat)
at kernel 3.3 or early. turbostat utility will read 10 registers one by one at
Sandybridge, so it will generate 10 IPIs to wake up idle CPUs. So cpuidle menu
 governor will predict it is repeat mode and there is another IPI wake up idle
 CPU soon, so it keeps idle CPU stay at C1 state even though CPU is totally
idle. However, in the turbostat, following 10 registers reading is sleep 5
seconds by default, so the idle CPU will keep at C1 for a long time though it is
 idle until break event occurs.
In a idle Sandybridge system, run "./turbostat -v", we will notice that deep
C-state dangles between "70% ~ 99%". After patched the kernel, we will notice
deep C-state stays at >99.98%.

In the patch, a timer is added when menu governor detects a repeat mode and
choose a shallow C-state. The timer is set to a time out value that greater
than predicted time, and we conclude repeat mode prediction failure if timer is
triggered. When repeat mode happens as expected, the timer is not triggered
and CPU waken up from C-states and it will cancel the timer initiatively.
When repeat mode does not happen, the timer will be time out and menu governor
will quickly notice that the repeat mode prediction fails and then re-evaluates
deeper C-states possibility.

Below is another case which will clearly show the patch much benefit:

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <signal.h>
#include <sys/time.h>
#include <time.h>
#include <pthread.h>

volatile int * shutdown;
volatile long * count;
int delay = 20;
int loop = 8;

void usage(void)
{
	fprintf(stderr,
		"Usage: idle_predict [options]\n"
		"  --help	-h  Print this help\n"
		"  --thread	-n  Thread number\n"
		"  --loop     	-l  Loop times in shallow Cstate\n"
		"  --delay	-t  Sleep time (uS)in shallow Cstate\n");
}

void *simple_loop() {
	int idle_num = 1;
	while (!(*shutdown)) {
		*count = *count + 1;

		if (idle_num % loop)
			usleep(delay);
		else {
			/* sleep 1 second */
			usleep(1000000);
			idle_num = 0;
		}
		idle_num++;
	}

}

static void sighand(int sig)
{
	*shutdown = 1;
}

int main(int argc, char *argv[])
{
	sigset_t sigset;
	int signum = SIGALRM;
	int i, c, er = 0, thread_num = 8;
	pthread_t pt[1024];

	static char optstr[] = "n:l:t:h:";

	while ((c = getopt(argc, argv, optstr)) != EOF)
		switch (c) {
			case 'n':
				thread_num = atoi(optarg);
				break;
			case 'l':
				loop = atoi(optarg);
				break;
			case 't':
				delay = atoi(optarg);
				break;
			case 'h':
			default:
				usage();
				exit(1);
		}

	printf("thread=%d,loop=%d,delay=%d\n",thread_num,loop,delay);
	count = malloc(sizeof(long));
	shutdown = malloc(sizeof(int));
	*count = 0;
	*shutdown = 0;

	sigemptyset(&sigset);
	sigaddset(&sigset, signum);
	sigprocmask (SIG_BLOCK, &sigset, NULL);
	signal(SIGINT, sighand);
	signal(SIGTERM, sighand);

	for(i = 0; i < thread_num ; i++)
		pthread_create(&pt[i], NULL, simple_loop, NULL);

	for (i = 0; i < thread_num; i++)
		pthread_join(pt[i], NULL);

	exit(0);
}

Get powertop V2 from git://github.com/fenrus75/powertop, build powertop.
After build the above test application, then run it.
Test plaform can be Intel Sandybridge or other recent platforms.
#./idle_predict -l 10 &
#./powertop

We will find that deep C-state will dangle between 40%~100% and much time spent
on C1 state. It is because menu governor wrongly predict that repeat mode
is kept, so it will choose the C1 shallow C-state even though it has chance to
sleep 1 second in deep C-state.

While after patched the kernel, we find that deep C-state will keep >99.6%.

Subject: [PATCH 1831/3298] cpuidle: Quickly notice prediction failure in
 general case

The prediction for future is difficult and when the cpuidle governor prediction
fails and govenor possibly choose the shallower C-state than it should. How to
quickly notice and find the failure becomes important for power saving.

The patch extends to general case that prediction logic get a small predicted
residency, so it choose a shallow C-state though the expected residency is large
. Once the prediction will be fail, the CPU will keep staying at shallow C-state
for a long time. Acutally, the CPU has change enter into deep C-state.
So when the expected residency is long enough but governor choose a shallow
C-state, an timer will be added in order to monitor if the prediction failure.

When C-state is waken up prior to the adding timer, the timer will be cancelled
initiatively. When the timer is triggered and menu governor will quickly notice
prediction failure and re-evaluates deeper C-states possibility.

Subject: [PATCH 1832/3298] cpuidle: Set residency to 0 if target Cstate not
 enter

When cpuidle governor choose a C-state to enter for idle CPU, but it notice that
there is tasks request to be executed. So the idle CPU will not really enter
the target C-state and go to run task.

In this situation, it will use the residency of previous really entered target
C-states. Obviously, it is not reasonable.

So, this patch fix it by set the target C-state residency to 0.

Subject: [PATCH 1833/3298] cpuidle: Get typical recent sleep interval

The function detect_repeating_patterns was not very useful for
workloads with alternating long and short pauses, for example
virtual machines handling network requests for each other (say
a web and database server).

Instead, try to find a recent sleep interval that is somewhere
between the median and the mode sleep time, by discarding outliers
to the up side and recalculating the average and standard deviation
until that is no longer required.

This should do something sane with a sleep interval series like:

	200 180 210 10000 30 1000 170 200

The current code would simply discard such a series, while the
new code will guess a typical sleep interval just shy of 200.

The original patch come from Rik van Riel <riel@redhat.com>.

Subject: [PATCH 1834/3298] cpuidle / sysfs: move structure declaration into
 the sysfs.c file

The structure cpuidle_state_kobj is not used anywhere except
in the sysfs.c file. The definition of this structure is not
needed in the cpuidle header file. This patch moves it to the
sysfs.c file in order to encapsulate the code a bit more.

Subject: [PATCH 1835/3298] cpuidle: fixup device.h header in cpuidle.h

The "struct device" is only used in sysfs.c.

The other .c files including the private header "cpuidle.h"
do not need to pull the entire headers tree from there as they
don't manipulate the "struct device".

This patch fixes this by moving the header inclusion to sysfs.c
and adding a forward declaration for the struct device.

Subject: [PATCH 1837/3298] cpuidle: move driver checking within the lock
 section

The code is racy and the check with cpuidle_curr_driver should be
done under the lock.

I don't find a path in the different drivers where that could happen
because the arch specific drivers are written in such way it is not
possible to register a driver while it is unregistered, except maybe
in a very improbable case when "intel_idle" and "processor_idle" are
competing. One could unregister a driver, while the other one is
registering.

Subject: [PATCH 1838/3298] cpuidle: prepare the cpuidle core to handle
 multiple drivers

This patch is a preparation for the multiple cpuidle drivers support.

As the next patch will introduce the multiple drivers with the Kconfig
option and we want to keep the code clean and understandable, this patch
defines a set of functions for encapsulating some common parts and splits
what should be done under a lock from the rest.

Subject: [PATCH 1839/3298] cpuidle: support multiple drivers

With the tegra3 and the big.LITTLE [1] new architectures, several cpus
with different characteristics (latencies and states) can co-exists on the
system.

The cpuidle framework has the limitation of handling only identical cpus.

This patch removes this limitation by introducing the multiple driver support
for cpuidle.

This option is configurable at compile time and should be enabled for the
architectures mentioned above. So there is no impact for the other platforms
if the option is disabled. The option defaults to 'n'. Note the multiple drivers
support is also compatible with the existing drivers, even if just one driver is
needed, all the cpu will be tied to this driver using an extra small chunk of
processor memory.

The multiple driver support use a per-cpu driver pointer instead of a global
variable and the accessor to this variable are done from a cpu context.

In order to keep the compatibility with the existing drivers, the function
'cpuidle_register_driver' and 'cpuidle_unregister_driver' will register
the specified driver for all the cpus.

The semantic for the output of /sys/devices/system/cpu/cpuidle/current_driver
remains the same except the driver name will be related to the current cpu.

The /sys/devices/system/cpu/cpu[0-9]/cpuidle/driver/name files are added
allowing to read the per cpu driver name.

Subject: [PATCH 1840/3298] PM / devfreq: Core updates to support devices which
 can idle

Prepare devfreq core framework to support devices which
can idle. When device idleness is detected perhaps through
runtime-pm, need some mechanism to suspend devfreq load
monitoring and resume back when device is online. Present
code continues monitoring unless device is removed from
devfreq core.

This patch introduces following design changes,

 - use per device work instead of global work to monitor device
   load. This enables suspend/resume of device devfreq and
   reduces monitoring code complexity.
 - decouple delayed work based load monitoring logic from core
   by introducing helpers functions to be used by governors. This
   provides flexibility for governors either to use delayed work
   based monitoring functions or to implement their own mechanism.
 - devfreq core interacts with governors via events to perform
   specific actions. These events include start/stop devfreq.
   This sets ground for adding suspend/resume events.

The devfreq apis are not modified and are kept intact.

Subject: [PATCH 1842/3298] PM / devfreq: Add current freq callback in device
 profile

Devfreq returns governor predicted frequency as current frequency
via sysfs interface. But device may not support all frequencies
that governor predicts. So add a callback in device profile to get
current freq from driver. Also add a new sysfs node to expose
governor predicted next target frequency.

sscanf returns 0 when an invalid parameter like:

cause the command not to return back to command
prompt.

Instead, just return -EINVAL when sscanf does not
return 1.

This is done for min_freq, max_freq and polling_interval

Subject: [PATCH 1848/3298] PM / OPP: predictable fail results for opp_find*
 functions, v2

Currently the opp_find* functions return -ENODEV when:
a) it cant find a device (e.g. request for an OPP search on device
   which was not registered)
b) When it cant find a match for the search strategy used

This makes life a little in-efficient for users such as devfreq
to make reasonable judgement before switching search strategies.

So, standardize the return results as following:
 -EINVAL for bad pointer parameters
 -ENODEV when device cannot be found
 -ERANGE when search fails

This has the following benefit for devfreq implementation:
The search fails when an unregistered device pointer is provided.
This is a trigger to change the search direction and search for
a better fit, however, if we cannot differentiate between a valid
search range failure Vs an unregistered device, second search goes
through the same fail return condition. This can be avoided by
appropriate handling of error return code.

With this change, we also fix devfreq for the improved search
strategy with updated error code.

Subject: [PATCH 1853/3298] driver core / PM: move the calling to
 device_pm_remove behind the calling to bus_remove_device

We hit an hang issue when removing a mmc device on Medfield Android phone by sysfs interface.

device_pm_remove will call pm_runtime_remove which would disable
runtime PM of the device. After that pm_runtime_get* or
pm_runtime_put* will be ignored. So if we disable the runtime PM
before device really be removed, drivers' _remove callback may
access HW even pm_runtime_get* fails. That is bad.

Consider below call sequence when removing a device:
device_del => device_pm_remove
             => class_intf->remove_dev(dev, class_intf)  => pm_runtime_get_sync/put_sync
             => bus_remove_device => device_release_driver => pm_runtime_get_sync/put_sync

remove_dev might call pm_runtime_get_sync/put_sync.
Then, generic device_release_driver also calls pm_runtime_get_sync/put_sync.
Since device_del => device_pm_remove firstly, later _get_sync wouldn't really wake up the device.

I git log -p to find the patch which moves the calling to device_pm_remove ahead.
It's below patch:

commit  775b64d2b6ca37697de925f70799c710aab5849a
Author: Rafael J. Wysocki <rjw@sisk.pl>
Date:   Sat Jan 12 20:40:46 2008 +0100

     PM: Acquire device locks on suspend

     This patch reorganizes the way suspend and resume notifications are
     sent to drivers.  The major changes are that now the PM core acquires
     every device semaphore before calling the methods, and calls to
     device_add() during suspends will fail, while calls to device_del()
     during suspends will block.

     It also provides a way to safely remove a suspended device with the
     help of the PM core, by using the device_pm_schedule_removal() callback
     introduced specifically for this purpose, and updates two drivers (msr
     and cpuid) that need to use it.

As device_pm_schedule_removal is deleted by another patch, we need also revert other parts of the patch,
i.e. move the calling of device_pm_remove after the calling to bus_remove_device.

Subject: [PATCH 1854/3298] staging: comedi: comedi_fc.h: introduce new helpers
 for do_cmdtest step 3

Step 3 of the do_cmdtest functions validates the arguments for the
command to be executed. Most of these are simple tests to see if the
argument "is" a value, a "min" value, or a "max" value. Each of these
tests then clamps the argument to the value if it fails the test.

Introduce three new helper functions in comedi_fc.h to handle these
tests and remove the boilerplate code from the drivers.

The new helper functions are:

cfc_check_trigger_arg_is()  - argument must be == the value
cfc_check_trigger_arg_min() - argument must be >= the value
cfc_check_trigger_arg_max() - argument must be <= the value

All of these helpers set the argument to the value and return -EINVAL
if the validation fails.

Subject: [PATCH 1898/3298] staging: comedi: ni_mio_common: use
 cfc_check_trigger_arg_*() helpers

Use the new helpers in the step 3 tests of ni_{ai,ao,cdio}_cmdtest().

Note that all the command triggers in ni_cdio_cmdtest are single source
so the extra tests are not required.

Subject: [PATCH 1899/3298] staging: comedi: addi_apci_1032: conform to new
 INSN_CONFIG_DIGITAL_TRIG

Conform to the new definition of the `INSN_CONFIG_DIGITAL_TRIG`
configuration instruction.

Return an error if the 'trigger number' in `data[1]` is non-zero or if
the configuration operation in `data[2]` is not supported.  Deal with
the 'left-shift' amount in `data[3]`.

The trigger's input channels can only be configured as a set of rising
and falling edges ('OR' mode) or as a set of high and low levels ('AND'
mode).  Preserve the old input channels to the right of the 'left-shift'
value except when switching modes.

(The 'left-shift' support is a bit of an overkill for this driver since
the trigger only has 16 input channels.)

Subject: [PATCH 1901/3298] staging: comedi: define operations for
 INSN_CONFIG_DIGITAL_TRIG

The 'addi_apci_1032' driver recently started supporting the
`INSN_CONFIG_DIGITAL_TRIG` configuration instruction, but as no other
drivers were using it before, there was no existing practice of how the
instruction should look.

Define the format to be something a bit more configurable.  In
particular, a subdevice might have more than one trigger requiring an ID
and/or `COMEDI_EV_...` flags to disambiguate them, a trigger might have
more than 32 inputs, and a trigger might need several
`INSN_CONFIG_DIGITAL_TRIG` configuration instructions to configure
completely (if there are more than 32 inputs or if it uses a combination
of edge-triggered and level-triggered inputs).

Subject: [PATCH 1902/3298] staging: comedi: remove old auto-config

All the Comedi drivers that call `comedi_pci_auto_config()` or
`comedi_usb_auto_config()` define a `auto_attach()` handler in their
`struct comedi_driver`.  There is no need to fall back to abusing the
`attach()` handler any more, so remove the code that supports that.

Subject: [PATCH 1906/3298] staging: comedi: simplify comedi_auto_attach()

`comedi_auto_config()` just calls internal function
`comedi_auto_config_helper()`, passing it a wrapper function
`comedi_auto_config_wrapper()` to handle the specifics of checking and
calling the low-level comedi driver's `auto_attach()` handler.

Since there are no other callers of `comedi_auto_config_helper()` or
`comedi_auto_config_wrapper()`, combine everything into the single
exported function `comedi_auto_config()`.

Change the ordering of the check for existence of the low-level comedi
driver's `auto_attach()` handler and the allocation of the comedi minor
device number.  This means the log message warning of the absence of the
handler now has to be refer to the hardware device instead of the
not-yet-allocated comedi device.

The usbmon feature should be used instead of manually dumping control

 * Can be turned on/off at runtime
 * Provides full USB-level traffic
 * tcpdump and wireshark support for powerful analysis
 * No driver-specific code is required

Subject: [PATCH 1913/3298] staging: line6: drop MIDI dumping code

ALSA amidi(1) and aseqdump(1) can be used to dump MIDI instead of
manually dumping MIDI messages in the driver.  The advantage of using
these existing tools is that can be used at run-time rather than
compile-time.

Subject: [PATCH 1934/3298] pstore: Fix NULL pointer dereference in console
 writes

Passing a NULL id causes a NULL pointer deference in writers such as
erst_writer and efi_pstore_write because they expect to update this id.
Pass a dummy id instead.

This avoids a cascade of oopses caused when the initial
pstore_console_write passes a null which in turn causes writes to the
console causing further oopses in subsequent pstore_console_write calls.

Subject: [PATCH 1935/3298] ipv4/ip_vti.c: VTI fix post-decryption forwarding

With the latest kernel there are two things that must be done post decryption
 so that the packet are forwarded.
 1. Remove the mark from the packet. This will cause the packet to not match
 the ipsec-policy again. However doing this causes the post-decryption check to
 fail also and the packet will get dropped. (cat /proc/net/xfrm_stat).
 2. Remove the sp association in the skbuff so that no policy check is done on
 the packet for VTI tunnels.

Due to #2 above we must now do a security-policy check in the vti rcv path
prior to resetting the mark in the skbuff.

Subject: [PATCH 1936/3298] drivers/net: fix tasklet misuse issue

In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet
on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable
in the driver init code, then tasklet_enable when it is opened. This makes
tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally,
drivers should use tasklet_init/tasklet_kill on device open/remove, and use
tasklet_disable/tasklet_enable on device suspend/resume.

Subject: [PATCH 1937/3298] net/smsc911x: Fix ready check in cases where
 WORD_SWAP is needed

The chip ready check added by the commit 3ac3546e [Always wait for
the chip to be ready] does not work when the register read/write
is word swapped. This check has been added before the WORD_SWAP
register is programmed, so we need to check for swapped register
value as well.

Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning
<steve@shawell.net> checked with SMSC and wrote:

  The chip architects have concluded we should be reading PMT_CTRL
  until we see any of bits 0, 8, 16 or 24 set.  Then we should read
  BYTE_TEST to check the byte order is correct (as we already do).

  The rationale behind this is that some of the chip variants have
  word order swapping features too, so the READY bit could actually
  be in any of the 4 possible locations.  The architects have confirmed
  that if any of these 4 positions is set the chip is ready.  The other
  3 locations will either never be set or can only go high after READY
  does (so also indicate the device is ready).

This change will check for the READY bit at the 16th position. We do
not check the other two cases (bit 8 and 24) since the driver does not
support byte-swapped register read/write.

Subject: [PATCH 1938/3298] Revert "drivers/net/phy/mdio-bitbang.c: Call
 mdiobus_unregister before mdiobus_free"

This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e.

As pointed out by Ben Hutchings, this change is not correct.

mdiobus_unregister() can't be called if the bus isn't registered yet,
however this change can result in situations which cause that to
happen.

Part of the confusion here revolves around the fact that the
callers of this module control registration/unregistration,
rather than the module itself.

Making the main driver a silent "bool" option avoid this potential

Subject: [PATCH 1950/3298] pinctrl: spear: Make get_gpio_pingroup return NULL
 when no gpio_pingroup found

Currently get_gpio_pingroup() may return NULL or ERR_PTR(-EINVAL) when
no gpio_pingroup found. The caller in gpio_request_endisable() only
checks if the return value is NULL. Return ERR_PTR(-EINVAL) for
get_gpio_pingroup() causes problem and seems not necessary.

Subject: [PATCH 1951/3298] pinctrl: plgpio: Call clk_disable_unprepare only if
 clk_prepare_enable is called

This driver allows clk_get() failure, and still work without it.
This patch adds !IS_ERR(plgpio->clk) checking in plgpio_request() error path
so we only call clk_disable_unprepare() if clk_prepare_enable() is called.

Commit e5cc8ef (ACPI / PM: Provide ACPI PM callback routines for
subsystems) introduced a build problem occuring if CONFIG_ACPI is
unset or CONFIG_PM is unset and errno.h is not included before
acpi.h, because in that case ENODEV used in acpi.h is undefined.

Fix the issue by making acpi.h include errno.h.

Subject: [PATCH 1954/3298] mtd: nand: fix Samsung SLC NAND identification
 regression

A combination of the following two commits caused a regression in 3.7-rc1
when identifying some Samsung NAND, so that some previously working NAND
were no longer detected properly:

    commit e3b88bd604283ef83ae6e8f53622d5b1ffe9d43a
    mtd: nand: add generic READ ID length calculation functions

    commit e2d3a35ee427aaba99b6c68a56609ce276c51270
    mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID

Particularly, a regression was seen on Samsung K9F2G08U0B, with the
following full 8-byte READ ID string:

    ec da 10 95 44 00 ec da

The basic problem is that Samsung manufactures both SLC and MLC NAND
that use a non-standard decoding table for deriving information from
their IDs. I have heuristically determined that all the chips that use
the new table have ID strings which wrap around after the 6th byte.
Unfortunately, I overlooked the fact that some older Samsung SLC (which
use a different decoding table) have "5 byte ID strings" which also wrap
around after the 6th byte.

This patch re-introduces a distinction between these old and new Samsung
NAND by checking that the 6th byte is non-zero, allowing both old and
new Samsung NAND to be detected properly.

Subject: [PATCH 1955/3298] mtd: nand: fix Samsung SLC detection regression

This patch fixes errors seen in identifying old Samsung SLC, due to the
following commits:

    commit e2d3a35ee427aaba99b6c68a56609ce276c51270
    mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID

    commit e3b88bd604283ef83ae6e8f53622d5b1ffe9d43a
    mtd: nand: add generic READ ID length calculation functions

Some Samsung NAND with "5-byte" ID really appear to have 6-byte IDs, with
wraparound like:

  Samsung K9K8G08U0D
  ec d3 51 95 58 ec ec d3

  Samsung K9F1G08U0C
  ec f1 00 95 40 ec ec f1

  Samsung K9F2G08U0B
  ec da 10 95 44 00 ec da

This bad wraparound makes it hard to reliably detect the difference
between Samsung SLC with 5-byte ID and Samsung SLC with 6-byte ID.

The fix is to, for now, only use the new Samsung table for MLC. We
cannot support the new SLC (K9FAG08U0M) until Samsung gives better ID
decode information.

Note that this applies in addition to the previous regression fix:

    commit bc86cf7af2ebda88056538e8edff852ee627f76a
    mtd: nand: fix Samsung SLC NAND identification regression

Together, these patches completely restore the previous detection
behavior so that we cannot see any more regressions in Samsung SLC NAND
(finger crossed). With luck, I can get a hold of a Samsung
representative and stop having to cross my fingers eventually.

This turns out to be correct and we need to pay attention to the pgoff as
well as the address when creating the virtual address for the area.
Fortunately, the bug is rarely triggered as most applications which use pgoff
tend to use large values (git being the primary one, and it uses pgoff in
multiples of 16MB) which are larger than our cache coherency modulus, so the
problem isn't often seen in practise.

Subject: [PATCH 1959/3298] s390/3215: fix tty close handling

The 3215 console always has the RAW3215_FIXED flag set, which causes
raw3215_shutdown() not to wait for outstanding I/O requests if an attached
tty gets closed.
The flag however can be simply removed, so we can guarantee that all requests
belonging to the tty have been processed when the tty is closed.

However the tasklet that belongs to the 3215 device may be scheduled even if
there is no tty attached anymore, since we have a race between console and tty
processing.
Thefore unconditional tty_wakekup() in raw3215_wakeup() can cause the following
NULL pointer dereference:

The easiest solution is simply to check if tty is NULL in the tasklet.
If it is NULL nothing is to do (no tty attached), otherwise tty_wakeup()
can be called, since we hold a reference to the tty.
This is not nice... but it is a small patch and it works.

Subject: [PATCH 1961/3298] bindings: i2c: use consistent naming for i2c
 binding descriptions

Filenames of devictree binding documentation seems to be arbitrary and
for me it is unneeded hazzle to find the corresponding documentation for
a specific driver.

Naming the description the same as the driver is a lot easier and makes
sense to me since the driver defines the binding it understands.

Also, remove a reference in one source to the binding documentation, since path
information easily gets stale.

Subject: [PATCH 1964/3298] sctp: fix /proc/net/sctp/ memory leak

Commit 13d782f ("sctp: Make the proc files per network namespace.")
changed the /proc/net/sctp/ struct file_operations opener functions to
use single_open_net() and seq_open_net().

Avoid leaking memory by using single_release_net() and seq_release_net()
as the release functions.

Discovered with Trinity (the syscall fuzzer).

Subject: [PATCH 1969/3298] clk: remove inline usage from clk-provider.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Users of GCC 4.7 have reported compiler errors due to having inline
applied to function declarations in clk-provider.h.  The definitions
exist in drivers/clk/clk.c.  An example error:

In file included from arch/arm/mach-omap2/clockdomain.c:25:0:
arch/arm/mach-omap2/clockdomain.c: In function ‘clkdm_clk_disable’:
include/linux/clk-provider.h:338:12: error: inlining failed in call to always_inline ‘__clk_get_enable_count’: function body not available
arch/arm/mach-omap2/clockdomain.c:1001:28: error: called from here
make[1]: *** [arch/arm/mach-omap2/clockdomain.o] Error 1
make: *** [arch/arm/mach-omap2] Error 2

This patch removes the use of inline from include/linux/clk-provider.h
but keeps the function definitions in drivers/clk/clk.c as inlined since
they are one-liners.

There is a typo here where '&' is used instead of '|' and it turns the

	iter->flags &= ~((1 << 2) & (1 << 4));

Subject: [PATCH 1971/3298] tcp: fix retransmission in repair mode

Currently if a socket was repaired with a few packet in a write queue,
a kernel bug may be triggered:

kernel BUG at net/ipv4/tcp_output.c:2330!
RIP: 0010:[<ffffffff8155784f>] tcp_retransmit_skb+0x5ff/0x610

According to the initial realization v3.4-rc2-963-gc0e88ff,
all skb-s should look like already posted. This patch fixes code
according with this sentence.

Here are three points, which were not done in the initial patch:
1. A tcp send head should not be changed
2. Initialize TSO state of a skb
3. Reset the retransmission time

This patch moves logic from tcp_sendmsg to tcp_write_xmit. A packet
passes the ussual way, but isn't sent to network. This patch solves
all described problems and handles tcp_sendpages.

Subject: [PATCH 1976/3298] mei: use type struct mei_cl *cl instead of void in
 struct mei_cb

We can use correct type 'struct mei_cl' instead of
'void *' for file_private in the struct mei_cb
as there is no other type assigned to this member of the structure

We rename the member from file_private to cl

Remove about 10 lines of declarations of temporary variables
used for type casting

Subject: [PATCH 1980/3298] mei: use link and unlink terms for connecting ME
 and HOST client

1. rename mei_me_cl_update_filext to mei_me_cl_link
2. rename mei_remove_client_from_file_list to mei_me_cl_unlink

Code style, documenation, and usage of both function is updated

Subject: [PATCH 1981/3298] mei: use the same bus msg for connect and
 disconnect request

structs hbm_client_connect_request and hbm_client_disconnect_request
have the same layout so we can drop the later

Add kdoc for the request and response structure so it is clear
they can be used for both purposes

Subject: [PATCH 1982/3298] tools: hv: Netlink source address validation allows
 DoS

The source code without this patch caused hypervkvpd to exit when it processed
a spoofed Netlink packet which has been sent from an untrusted local user.
Now Netlink messages with a non-zero nl_pid source address are ignored
and a warning is printed into the syslog.

Subject: [PATCH 1983/3298] tools/hv: Fix string types

Initial patch by Ben Hutchings <ben@decadent.org.uk>

Standard C strings are arrays of char, not __u8 (unsigned char).
Declare variables and parameters accordingly, and add the necessary
casts.

Subject: [PATCH 1984/3298] mm: export a function to get vm committed memory

It will be useful to be able to access global memory commitment from
device drivers.  On the Hyper-V platform, the host has a policy engine to
balance the available physical memory amongst all competing virtual
machines hosted on a given node.  This policy engine is driven by a number
of metrics including the memory commitment reported by the guests.  The
balloon driver for Linux on Hyper-V will use this function to retrieve
guest memory commitment.  This function is also used in Xen self
ballooning code.

Subject: [PATCH 1985/3298] Drivers: hv: Add Hyper-V balloon driver

Add the basic balloon driver. Windows hosts dynamically manage the guest
memory allocation via a combination memory hot add and ballooning. Memory
hot add is used to grow the guest memory upto the maximum memory that can be
allocatted to the guest. Ballooning is used to both shrink as well as expand
up to the max memory. Supporting hot add needs additional support from the
host. We will support hot add when this support is available. For now,
by setting the VM startup memory to the VM  max memory, we can use
ballooning alone to dynamically manage memory allocation amongst
competing guests on a given host.

copy_to_user() returns the number of bytes remaining to be copied, but
we want to return a negative error code here.  I fixed a couple of these
last year, but I missed this one.

Subject: [PATCH 1991/3298] serial:ifx6x60:SPI header is decoded incorrectly

This patch is to correct the bit mapping of "MORE" and "CTS" in SPI frame header.
Per SPI protocol, SPI header is encoded with length of 4 byte, which is defined
as below:
bit 0 ~ 11: current data size;
bit 12: "MORE" bit;
bit 13: reserve
bit 14 ~ 15: reserve
bit 16 ~ 27: next data size
bit 28: RI
bit 29: DCD
bit 30: CTS/RTS
bit 31: DSR/DTR

According to above SPI header structure, the bit mapping of "MORE" and "CTS" is
incorrect in function ifx_spi_decode_spi_header();

Subject: [PATCH 1995/3298] ACPI / memory-hotplug: add memory offline code to
 acpi_memory_device_remove()

The memory device can be removed by 2 ways:
 1. send eject request by SCI
 2. echo 1 >/sys/bus/pci/devices/PNP0C80:XX/eject

In the 1st case, acpi_memory_disable_device() will be called.
In the 2nd case, acpi_memory_device_remove() will be called.
acpi_memory_device_remove() will also be called when we unbind the
memory device from the driver acpi_memhotplug or a driver initialization
fails.

acpi_memory_disable_device() has already implemented a code which
offlines memory and releases acpi_memory_info struct. But
acpi_memory_device_remove() has not implemented it yet.

So the patch move offlining memory and releasing acpi_memory_info struct
codes to a new function acpi_memory_remove_memory(). And it is used by both
acpi_memory_device_remove() and acpi_memory_disable_device().

Subject: [PATCH 1996/3298] USB: fix authorization and claimed port logic

    It looks like I've run into some inconsistency in the USB stack behavior.

    The USB stack maintains, among others, two states for the attach
USB device: authorized and owned. Authorization state is accessible to
the user space code through correspondent sysfs files, the ownership
can be set by claiming the hub's port with ioctl call. Both state may
be set before the device is attached, by access the hub settings. When
the new device is attached, both authorization and ownership prevent
the kernel USB stack from setting the newly attached device
configuration, but when the device is authorized, the ownership state
is ignored. It looks like ignoring the ownership state on
authorization make the stack behavior inconsistent; it also prevents
the user space code from completely overriding configuration
selection, important for implementing workarounds for bugs in the
device configuration selection.

   The following patch makes the stack behavior more consistent, by
moving ownership test into usb_choose_configuration - the later
function is used both by generic_probe and usb_authorize_device

The memory device can be removed by 2 ways:
 1. send eject request by SCI
 2. echo 1 >/sys/bus/pci/devices/PNP0C80:XX/eject

We handle the 1st case in the module acpi_memhotplug, and handle
the 2nd case in ACPI eject notification. This 2 events may happen
at the same time, so we may touch acpi_memory_device.res_list at
the same time. This patch reimplements memory-hotremove support
through an ACPI eject notification. Now the memory device is
offlined and hotremoved only in the function acpi_memory_device_remove()
which is protected by device_lock().

Subject: [PATCH 2010/3298] TTY: pty, fix tty buffers leak

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

PTY is one of those, here we just need to use tty_port_put instead of
kfree. (Assuming tty_port_destructor does not need port->ops to be set
which we change here too.)

Subject: [PATCH 2014/3298] TTY: n_gsm, use kref from tty_port

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

Here it is enough to switch to refcounting in tty_port.

Subject: [PATCH 2015/3298] TTY: introduce tty_port_destroy

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue.

Those using refcounting are safe now, but for those which do not we
introduce a function to be called right before the tty_port is freed
by the drivers.

Subject: [PATCH 2016/3298] TTY: isicom, fix tty buffers memory leak

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

This one is special as we need more work to be done. Previously,
the tty_port was initialized at module load time, but to be able to
destroy the port and init it again, we now do the initialization in
probe and destroy in remove. I.e. at more appropriate places for that.

Subject: [PATCH 2017/3298] TTY: call tty_port_destroy in the rest of drivers

After commit "TTY: move tty buffers to tty_port", the tty buffers are
not freed in some drivers. This is because tty_port_destructor is not
called whenever a tty_port is freed. This was an assumption I counted
with but was unfortunately untrue. So fix the drivers to fulfil this
assumption.

To be sure, the TTY buffers (and later some stuff) are gone along with
the tty_port, we have to call tty_port_destroy at tear-down places.
This is mostly where the structure containing a tty_port is freed.
This patch does exactly that -- put tty_port_destroy at those places.

Subject: [PATCH 2018/3298] drivers/parport: remove depends on
 CONFIG_EXPERIMENTAL

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

Subject: [PATCH 2024/3298] misc: hpilo: ignore auxiliary HP iLO BMC's

This patch ignores auxiliary HP Lights-Out (iLO) management controllers.

All HP iLO controllers that have had the PCI subsystem device ID set to 0x1979
by the BIOS are ignored. Also changes default number of channels to 16 and
bumps the version of the module from 1.3 to 1.4.

Subject: [PATCH 2026/3298] cdc-acm: implement TIOCSSERIAL to avoid blocking
 close(2)

Some devices (ex Nokia C7) simply don't respond at all when data is sent
to some of their USB interfaces.  The data gets stuck in the TTYs queue
and sits there until close(2), which them blocks because closing_wait
defaults to 30 seconds (even though the fd is O_NONBLOCK).  This is
rarely desired.  Implement the standard mechanism to adjust closing_wait
and let applications handle it how they want to.

See also 02303f73373aa1da19dbec510ec5a4e2576f9610 for usb_wwan.c.

The real reason causes mx23 fail are:

- Calling mxs_phy_hw_init(mxs_phy) again at connection
- Error connect/disconnect nodity at hub.c

The coming patch will fix above two problems, Mike Thompson
tested his hardware works OK after commented out this delay
setting.

This reverts commit 363366cf61c544ea476f3d220f43a95cb03014f5.

Subject: [PATCH 2029/3298] usb: refine phy notify operation during connection
 and disconnection

At commit 925aa46ba963a4da6d8ee6ab1d04a02ffa8db62b, Richard Zhao
<richard.zhao@freescale.com> adds the phy notification callback
when port change occurs. In fact, this phy notification should
be added according to below rules:

1. Only set HW_USBPHY_CTRL.ENHOSTDISCONDETECT
during high speed host mode.
2. Do not set HW_USBPHY_CTRL.ENHOSTDISCONDETECT
during the reset and speed negotiation period.
3. Do not set HW_USBPHY_CTRL.ENHOSTDISCONDETECT
during host suspend/resume sequence.

Please refer: i.mx23RM(page: 413) for below rules.
http://www.freescale.com/files/dsp/doc/ref_manual/IMX23RM.pdf

Freescale i.MX SoC, i.mx23, i.mx28 and i.mx6(i.mx6SL does not
need to follow the 3rd rule) need to follow above rules.

Current code set connect notification (HW_USBPHY_CTRL.ENHOSTDISCONDETECT)
at hub_port_connect_change, it conflicts with above the 2th rule.

The correct notification setting method should be:
1. Set connect notify after the second bus reset.
2. Set disconnect notify after disconnection.

The old parameter "port" is useless for phy notify, as one usb
phy is only for one usb port. New parameter "speed" stands for
the device's speed which is on the port, this "speed" parameter
is needed at some platforms which will do some phy operations
according to device's speed.

+内核提供的用户空间辅助代码
+=========================
+
+在内核内存空间的固定地址处，有一个由内核提供并可从用户空间访问的代码
+段。它用于向用户空间提供因在许多 ARM CPU 中未实现的特性和/或指令而需
+内核提供帮助的某些操作。这些代码直接在用户模式下执行的想法是为了获得
+最佳效率，但那些与内核计数器联系过于紧密的部分，则被留给了用户库实现。
+事实上，此代码甚至可能因不同的 CPU 而异，这取决于其可用的指令集或它
+是否为 SMP 系统。换句话说，内核保留在不作出警告的情况下根据需要更改
+这些代码的权利。只有本文档描述的入口及其结果是保证稳定的。
+
+这与完全成熟的 VDSO 实现不同（但两者并不冲突），尽管如此，VDSO 可阻止
+某些通过常量高效跳转到那些代码段的汇编技巧。且由于那些代码段在返回用户
+代码前仅使用少量的代码周期，则一个 VDSO 间接远程调用将会在这些简单的
+操作上增加一个可测量的开销。
+
+在对那些拥有原生支持的新型处理器进行代码优化时，仅在已为其他操作使用
+了类似的新增指令，而导致二进制结果已与早期 ARM 处理器不兼容的情况下，
+用户空间才应绕过这些辅助代码，并在内联函数中实现这些操作（无论是通过
+编译器在代码中直接放置，还是作为库函数调用实现的一部分）。也就是说，
+如果你编译的代码不会为了其他目的使用新指令，则不要仅为了避免使用这些
+内核辅助代码，导致二进制程序无法在早期处理器上运行。
+
+新的辅助代码可能随着时间的推移而增加，所以新内核中的某些辅助代码在旧
+内核中可能不存在。因此，程序必须在对任何辅助代码调用假设是安全之前，
+检测 __kuser_helper_version 的值（见下文）。理想情况下，这种检测应该
+只在进程启动时执行一次；如果内核版本不支持所需辅助代码，则该进程可尽早
+中止执行。
+
+kuser_helper_version
+--------------------
+
+位置:	0xffff0ffc
+
+参考声明:
+
+  extern int32_t __kuser_helper_version;
+
+定义:
+
+  这个区域包含了当前运行内核实现的辅助代码版本号。用户空间可以通过读
+  取此版本号以确定特定的辅助代码是否存在。
+
+使用范例:
+
+#define __kuser_helper_version (*(int32_t *)0xffff0ffc)
+
+void check_kuser_version(void)
+{
+	if (__kuser_helper_version < 2) {
+		fprintf(stderr, "can't do atomic operations, kernel too old\n");
+		abort();
+	}
+}
+
+注意:
+
+  用户空间可以假设这个域的值不会在任何单个进程的生存期内改变。也就
+  是说，这个域可以仅在库的初始化阶段或进程启动阶段读取一次。
+
+kuser_get_tls
+-------------
+
+位置:	0xffff0fe0
+
+参考原型:
+
+  void * __kuser_get_tls(void);
+
+输入:
+
+  lr = 返回地址
+
+输出:
+
+  r0 = TLS 值
+
+被篡改的寄存器:
+
+  无
+
+定义:
+
+  获取之前通过 __ARM_NR_set_tls 系统调用设置的 TLS 值。
+
+使用范例:
+
+typedef void * (__kuser_get_tls_t)(void);
+#define __kuser_get_tls (*(__kuser_get_tls_t *)0xffff0fe0)
+
+void foo()
+{
+	void *tls = __kuser_get_tls();
+	printf("TLS = %p\n", tls);
+}
+
+注意:
+
+  - 仅在 __kuser_helper_version >= 1 时，此辅助代码存在
+    （从内核版本 2.6.12 开始）。
+
+kuser_cmpxchg
+-------------
+
+位置:	0xffff0fc0
+
+参考原型:
+
+  int __kuser_cmpxchg(int32_t oldval, int32_t newval, volatile int32_t *ptr);
+
+输入:
+
+  r0 = oldval
+  r1 = newval
+  r2 = ptr
+  lr = 返回地址
+
+输出:
+
+  r0 = 成功代码 (零或非零)
+  C flag = 如果 r0 == 0 则置 1，如果 r0 != 0 则清零。
+
+被篡改的寄存器:
+
+  r3, ip, flags
+
+定义:
+
+  仅在 *ptr 为 oldval 时原子保存 newval 于 *ptr 中。
+  如果 *ptr 被改变，则返回值为零，否则为非零值。
+  如果 *ptr 被改变，则 C flag 也会被置 1，以实现调用代码中的汇编
+  优化。
+
+使用范例:
+
+typedef int (__kuser_cmpxchg_t)(int oldval, int newval, volatile int *ptr);
+#define __kuser_cmpxchg (*(__kuser_cmpxchg_t *)0xffff0fc0)
+
+int atomic_add(volatile int *ptr, int val)
+{
+	int old, new;
+
+	do {
+		old = *ptr;
+		new = old + val;
+	} while(__kuser_cmpxchg(old, new, ptr));
+
+	return new;
+}
+
+注意:
+
+  - 这个例程已根据需要包含了内存屏障。
+
+  - 仅在 __kuser_helper_version >= 2 时，此辅助代码存在
+    （从内核版本 2.6.12 开始）。
+
+kuser_memory_barrier
+--------------------
+
+位置:	0xffff0fa0
+
+参考原型:
+
+  void __kuser_memory_barrier(void);
+
+输入:
+
+  lr = 返回地址
+
+输出:
+
+  无
+
+被篡改的寄存器:
+
+  无
+
+定义:
+
+  应用于任何需要内存屏障以防止手动数据修改带来的一致性问题，以及
+  __kuser_cmpxchg 中。
+
+使用范例:
+
+typedef void (__kuser_dmb_t)(void);
+#define __kuser_dmb (*(__kuser_dmb_t *)0xffff0fa0)
+
+注意:
+
+  - 仅在 __kuser_helper_version >= 3 时，此辅助代码存在
+    （从内核版本 2.6.15 开始）。
+
+kuser_cmpxchg64
+---------------
+
+位置:	0xffff0f60
+
+参考原型:
+
+  int __kuser_cmpxchg64(const int64_t *oldval,
+                        const int64_t *newval,
+                        volatile int64_t *ptr);
+
+输入:
+
+  r0 = 指向 oldval
+  r1 = 指向 newval
+  r2 = 指向目标值
+  lr = 返回地址
+
+输出:
+
+  r0 = 成功代码 (零或非零)
+  C flag = 如果 r0 == 0 则置 1，如果 r0 != 0 则清零。
+
+被篡改的寄存器:
+
+  r3, lr, flags
+
+定义:
+
+  仅在 *ptr 等于 *oldval 指向的 64 位值时，原子保存 *newval
+  指向的 64 位值于 *ptr 中。如果 *ptr 被改变，则返回值为零，
+  否则为非零值。
+
+  如果 *ptr 被改变，则 C flag 也会被置 1，以实现调用代码中的汇编
+  优化。
+
+使用范例:
+
+typedef int (__kuser_cmpxchg64_t)(const int64_t *oldval,
+                                  const int64_t *newval,
+                                  volatile int64_t *ptr);
+#define __kuser_cmpxchg64 (*(__kuser_cmpxchg64_t *)0xffff0f60)
+
+int64_t atomic_add64(volatile int64_t *ptr, int64_t val)
+{
+	int64_t old, new;
+
+	do {
+		old = *ptr;
+		new = old + val;
+	} while(__kuser_cmpxchg64(&old, &new, ptr));
+
+	return new;
+}
+
+注意:
+
+  - 这个例程已根据需要包含了内存屏障。
+
+  - 由于这个过程的代码长度（此辅助代码跨越 2 个常规的 kuser “槽”），
+    因此 0xffff0f80 不被作为有效的入口点。
+
+  - 仅在 __kuser_helper_version >= 5 时，此辅助代码存在
+    （从内核版本 3.1 开始）。

Subject: [PATCH 2038/3298] ACPI: create _SUN sysfs file

_SUN method provides the slot unique-ID in the ACPI namespace. And The value
is written in Advanced Configuration and Power Interface Specification as
follows:

"The _SUN value is required to be unique among the slots ofthe same type.
It is also recommended that this number match the slot number printed on
the physical slot whenever possible."

So if we can know the value, we can identify the physical position of the
slot in the system.

The patch creates "sun" file in sysfs for identifying physical position
of the slot.

Subject: [PATCH 2041/3298] Partially revert "serial: sh-sci: console Runtime
 PM support"

This partially reverts commit 1ba7622094 (serial: sh-sci: console
Runtime PM support, from Magnus Damm <damm@opensource.se>, 2011-08-03).

The generic 'serial_core' can take care of console PM maintenance,
so all (or at least the first thing) we have to do to get console PM
work properly, is to implement uart_ops ->pm() operation in the sh-sci
serial client driver.

This patch partially reverts the commit above, but leaving sci_reset()
change in place, because sci_reset() is already part of another commit
(73c3d53f38 serial: sh-sci: Avoid FIFO clear for MCE toggle.).

A revised version of console PM support follows next.

Subject: [PATCH 2042/3298] serial: sh-sci: console runtime PM support
 (revisit)

The commit 1ba7622094 (serial: sh-sci: console Runtime PM support,
from Magnus Damm <damm@opensource.se>, 2011-08-03), tried to support
console runtime PM, but unfortunately it didn't work for us for some
reason.  We did not investigated further at that time, instead would
like to propose a different approach.

In Linux tty/serial world, to get console PM work properly, a serial
client driver does not have to maintain .runtime_suspend()/..resume()
calls itself, but can leave console power power management handling to
the serial core driver.

This patch moves the sh-sci driver in that direction.

Notes:

* There is room to optimize console runtime PM more aggressively by
  maintaining additional local runtime PM calls, but as a first step
  having .pm() operation would suffice.

* We still have a couple of direct calls to sci_port_enable/..disable
  left in the driver.  We have to live with them, because they're out
  of serial core's help.

Support prescaler 1/16 and 1/64, in addition to current 1 and 1/4.

Supporting below 2400bps was dropped long time ago in mainline.
Since then, setting lower rate has been resulting in erroneous
register value, without indicating any errors through API.

This patch adds more prescaler to support lower rates again.
This still doesn't check range, but we won't hit the case because
even 50bps at 48MHz clock is now supported.

Subject: [PATCH 2045/3298] serial: sh-sci: mask SCTFDR/RFDR according to
 fifosize

Current mask 0xff to SCTFDR/RFDR damages SCIFB, because the
registers on SCIFB have 9-bit data (0 to 256).

This patch changes the mask according to port->fifosize.
Though I'm not sure if the mask is really needed (I don't know if
there are variants which have non-zero upper bits), it is safer.

Subject: [PATCH 2046/3298] serial: sh-sci: fix common SCIFB regmap definition

About FIFO count, there are two variants of SCIFs which show
a) TX count in upper, RX count in lower byte of FDR register
b) TX count in TFDR register, RX count in RFDR register

Common SCIFB regmap in current source code is defined as "a".
At least 7372 and 73a0 HW manual say their SICFB are "b".

This patch alters the definition to "b", considering the current
one has come from a mistake. The reason is as follows.

The flag SCIFB sh-sci driver means it has 256 byte FIFO.
The count is from 0(empty) to 256(full), that makes 9-bit.
Because FDR is 16-bit register, it can not hold two 9-bits.
That's why, SCIFB can not be "a".

Subject: [PATCH 2047/3298] serial: sh-sci: add locking to console write
 function to avoid SMP lockup

Symptom:

When entering the suspend with Android logcat running, printk() call
gets stuck and never returns.  The issue can be observed at printk()s
on nonboot CPUs when going to offline with their interrupts disabled,
and never seen at boot CPU (core0 in our case).

Details:

serial_console_write() lacks of appropriate spinlock handling.

In SMP systems, as long as sci_transmit_chars() is being processed
at one CPU core, serial_console_write() can stuck at the other CPU
core(s), when it tries to access to the same serial port _without_
a proper locking.  serial_console_write() waits for the transmit FIFO
getting empty, while sci_transmit_chars() writes data to the FIFO.

In general, peripheral interrupts are routed to boot CPU (core0) by
Linux ARM standard affinity settings.  SCI(F) interrupts are handled
by core0, so sci_transmit_chars() is processed on core0 as well.

When logcat is running, it writes enormous log data to the kernel at
every moment, forever.  So core0 can repeatedly continue to process
sci_transmit_chars() in its interrupt handler, which eventually makes
the other CPU core(s) stuck at serial_console_write().

Looking at serial/8250.c, this is a known console write lockup issue
with SMP kernels.  Fix the sh-sci driver in the same way 8250.c does.

Subject: [PATCH 2048/3298] serial: sh-sci: fix possible race cases on SCSCR
 register accesses

In the previous commit, console write function (serial_console_write)
is changed to disable SCI interrupts while printing console strings.
This introduces possible race cases in the serial startup / shutdown
functions on SMP systems.

This patch fixes the sh-sci in the same way as commit 9ec1882df2
(tty: serial: imx: console write routing is unsafe on SMP, from
Xinyu Chen <xinyu.chen@freescale.com>, 2012-08-27) did.

There could be several consumers of the console,
* the kernel printk
* the init process using /dev/kmsg to call printk to show log
* shell, which opens /dev/console and writes with sys_write()

The shell goes into the normal UART open() and write() system calls,
while the other two go into the console operations.  The open() call
invokes serial startup function (sci_startup), which will write to
the SCSCR register (to enable or disable SCI interrupts) without any
locking.  This will conflict with the console serial function.

Add spinlock protections in sci_startup() and sci_shutdown() properly.

a problem if for some reason the device only becomes operational
after loading another module.

Using __devinit instead avoids seeing this warning for every build:

Subject: [PATCH 2055/3298] tilegx: request_irq with a non-null device name

This patch simply makes the tilegx net driver call request_irq with a
non-null name. It makes the output in /proc/interrupts more obvious, but
also helps tools that don't expect to find null there.

Subject: [PATCH 2056/3298] batman-adv: fix tt_global_entries flags update

Flags carried by a change_entry have to be always copied into the
client entry as they may contain important attributes (e.g.
TT_CLIENT_WIFI).

For instance, a client added by means of the "early detection
mechanism" has no flag set at the beginning, so they must be updated once the
proper ADD event is received.

 earlier

The logic in the BLA mechanism may decide to drop broadcast packets
because the node may still be in the setup phase. For this reason,
further broadcast processing like the early client detection mechanism
must be done only after the BLA check.

This patches moves the invocation to BLA before any other broadcast
processing.

Subject: [PATCH 2062/3298] Revert "ACPI / x86: Add quirk for "CheckPoint
 P-20-00" to not use bridge _CRS_ info"

This reverts commit 0a290ac4252c85205cb924ff7f6da10cfd20fb01 on
the basis of the following comment from Bjorn Helgaas:

  Here's my reasoning: this is a CheckPoint product, and it looks
  like an appliance, not really a general-purpose machine.  The issue
  has apparently been there from day one, and the kernel shipped on
  the machine complains noisily about the issue, but apparently
  nobody bothered to investigate it.

  This corruption will clearly break other ACPI-related things.  We
  can sort of work around this one (though the workaround does
  prevent us from doing any PCI resource reassignment), but we have
  no idea what the other lurking ACPI issues are (and we have no
  assurance that *only* ACPI things are broken -- maybe the
  memory corruption affects other unknown things).  It may take
  significant debugging effort to identify the next problem.

  The only report I've seen (this one) is apparently from a
  CheckPoint employee, so it's not clear that anybody else is trying
  to run upstream Linux on it.  Being a CheckPoint employee, [...]
  is probably in a position to get the BIOS fixed.

  You might still be able to convince me, but it seems like the
  benefit to a quirk for this platform is small, and it does cost
  everybody else something in code size and complexity.

Subject: [PATCH 2064/3298] tty/8250_early: Turn serial_in/serial_out into weak
 symbols.

Allows overriding default methods serial_in/serial_out.

In such platform specific replacement it is possible to use
other regshift, biased register offset, any other manipulation
that is not covered with common default methods.

Overriding default methods may be useful for platforms which got
serial peripheral with registers represented in big endian.
In this situation and assuming that 32 bit operations / alignment
is required then it may be useful to swab words before/after
accessing the serial registers.

Subject: [PATCH 2065/3298] serial: mxs-auart: distinguish the different SOCs

The current mxs-auart driver is used for both mx23 and mx28.

But in mx23, the DMA has a bug(see errata:2836). We can not add the
DMA support in mx23, but we can add DMA support to auart in mx28.

So in order to add the DMA support for the auart in mx28, we should
distinguish the distinguish SOCs.

This patch adds a new platform_device_id table and a inline function
is_imx28_auart() to distinguish the mx23 and mx28.

Subject: [PATCH 2066/3298] serial: mxs-auart: add the DMA support for mx28

Only we meet the following conditions, we can enable the DMA support for
auart:

  (1) We enable the DMA support in the dts file, such as
      arch/arm/boot/dts/imx28.dtsi.

  (2) We enable the hardware flow control.

  (3) We use the mx28, not the mx23. Due to hardware bug(see errata: 2836),
      we can not add the DMA support to mx23.

 dwc3_alloc_event_buffers

commit 392142 moved event buffer allocation out of dwc3_core_init() but
event buffer allocation uses the cached copy of hwparams to determine
the number of event buffers and the caching is done in dwc3_core_init.
So moved dwc3_cache_hwparams function before dwc3_alloc_event_buffers so
that dwc3_alloc_event_buffers sees the correct number of event buffers.

In the case of timeout waiting for data ready, the retry variable is -1.
This also fixes a bug: current code returns -ETIMEDOUT if latest retry success
( which means retry is 0 when exiting the while loop ).

Subject: [PATCH 2070/3298] uprobes: Use percpu_rw_semaphore to fix
 register/unregister vs dup_mmap() race

This was always racy, but 268720903f87e0b84b161626c4447b81671b5d18
"uprobes: Rework register_for_each_vma() to make it O(n)" should be
blamed anyway, it made everything worse and I didn't notice.

register/unregister call build_map_info() and then do install/remove
breakpoint for every mm which mmaps inode/offset. This can obviously
race with fork()->dup_mmap() in between and we can miss the child.

uprobe_register() could be easily fixed but unregister is much worse,
the new mm inherits "int3" from parent and there is no way to detect
this if uprobe goes away.

So this patch simply adds percpu_down_read/up_read around dup_mmap(),
and percpu_down_write/up_write into register_for_each_vma().

This adds 2 new hooks into dup_mmap() but we can kill uprobe_dup_mmap()
and fold it into uprobe_end_dup_mmap().

Subject: [PATCH 2072/3298] ARM: imx: ehci: fix host power mask bit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch sets HPM (Host power mask bit) to bit 16 according to i.MX
Reference Manual. Falsely it was set to bit 8, but this controls pull-up
Impedance.

Subject: [PATCH 2073/3298] staging: Add SystemBase Multi-2/PCI driver

I ported the driver supplied by SystemBase to mainline.

As the driver had MODULE_LICENSE("GPL") it is declared as a GPL module
and thus I have the right to distribute it upstream. Note, I did the
bare minimum to get it working. It still needs a lot of loving.

Subject: [PATCH 2074/3298] arm64: Distinguish between user and kernel XN bits

On AArch64, the meaning of the XN bit has changed to UXN (user). The PXN
(privileged) bit must be set to prevent kernel execution. Without the
PXN bit set, the CPU may speculatively access device memory. This patch
ensures that all the mappings that the kernel must not execute from
(including user mappings) have the PXN bit set.

 top-level directory "rcu":
 
-rcu/rcudata:
+rcu/rcu_bh
+rcu/rcu_preempt

+
+Each directory contains files for the corresponding flavor of RCU.
+Note that rcu/rcu_preempt is only present for CONFIG_TREE_PREEMPT_RCU.
+For CONFIG_TREE_RCU, the RCU flavor maps onto the RCU-sched flavor,
+so that activity for both appears in rcu/rcu_sched.
+
+In addition, the following file appears in the top-level directory:
+rcu/rcutorture.  This file displays rcutorture test progress.  The output
+of "cat rcu/rcutorture" looks as follows:
+
+rcutorture test sequence: 0 (test in progress)
+rcutorture update version number: 615
+
+The first line shows the number of rcutorture tests that have completed
+since boot.  If a test is currently running, the "(test in progress)"
+string will appear as shown above.  The second line shows the number of
+update cycles that the current test has started, or zero if there is
+no test in progress.
+
+
+Within each flavor directory (rcu/rcu_bh, rcu/rcu_sched, and possibly
+also rcu/rcu_preempt) the following files will be present:
+
+rcudata:
 	Displays fields in struct rcu_data.

-rcu/rcu_pending:

 	Displays counts of the reasons rcu_pending() decided that RCU had
 	work to do.

Subject: [PATCH 2081/3298] rcu: Add callback-free CPUs

RCU callback execution can add significant OS jitter and also can
degrade both scheduling latency and, in asymmetric multiprocessors,
energy efficiency.  This commit therefore adds the ability for selected
CPUs ("rcu_nocbs=" boot parameter) to have their callbacks offloaded
to kthreads.  If the "rcu_nocb_poll" boot parameter is also specified,
these kthreads will do polling, removing the need for the offloaded
CPUs to do wakeups.  At least one CPU must be doing normal callback
processing: currently CPU 0 cannot be selected as a no-CBs CPU.
In addition, attempts to offline the last normal-CBs CPU will fail.

This feature was inspired by Jim Houston's and Joe Korty's JRCU, and
this commit includes fixes to problems located by Fengguang Wu's
kbuild test robot.

[ paulmck: Added gfp.h include file as suggested by Fengguang Wu. ]

Subject: [PATCH 2082/3298] rcu: Separate accounting of callbacks from
 callback-free CPUs

Currently, callback invocations from callback-free CPUs are accounted to
the CPU that registered the callback, but using the same field that is
used for normal callbacks.  This makes it impossible to determine from
debugfs output whether callbacks are in fact being diverted.  This commit
therefore adds a separate ->n_nocbs_invoked field in the rcu_data structure
in which diverted callback invocations are counted.  RCU's debugfs tracing
still displays normal callback invocations using ci=, but displayed

Subject: [PATCH 2084/3298] mm, oom: reintroduce /proc/pid/oom_adj

This is mostly a revert of 01dc52ebdf47 ("oom: remove deprecated oom_adj")
from Davidlohr Bueso.

It reintroduces /proc/pid/oom_adj for backwards compatibility with earlier
kernels.  It simply scales the value linearly when /proc/pid/oom_score_adj
is written.

The major difference is that its scheduled removal is no longer included
in Documentation/feature-removal-schedule.txt.  We do warn users with a
single printk, though, to suggest the more powerful and supported
/proc/pid/oom_score_adj interface.

Subject: [PATCH 2088/3298] ipack: remove ipack_ids.h file

Its contents are merged into ipack.h. So this file is not needed.

Doing that, it simplifies the ipack-related driver development.

In commit c445477d74ab3779 which adds aRFS to the kernel, the CPU
selected for RFS is not set correctly when CPU is changing.
This is causing OOO packets and probably other issues.

Subject: [PATCH 2091/3298] mwifiex: fix system hang issue in cmd timeout error
 case

Reported by Tim Shepard:
I was seeing sporadic failures (wedgeups), and the majority of those
failures I saw printed the printouts in mwifiex_cmd_timeout_func with
cmd = 0xe5 which is CMD_802_11_HS_CFG_ENH.  When this happens, two
minutes later I get notified that the rtcwake thread is blocked, like
this:
      INFO: task rtcwake:3495 blocked for more than 120 seconds.

To get the hung thread unblocked we wake up the cmd wait queue and
cancel the ioctl.

Currently acpi_dev_process_resource() returns AE_ABORT_METHOD
to terminate the acpi_walk_resources() it is called from if
the .preproc() routine provided by the caller of
acpi_dev_get_resources() initiating the resources walk returns
an error code.  It is better to use AE_CTRL_TERMINATE for this

Subject: [PATCH 2095/3298] ACPI / battery: Correct battery capacity values on
 Thinkpads

Add a quirk to correctly report battery capacity on 2010 and 2011
Lenovo Thinkpad models.

The affected models that I tested (x201, t410, t410s, and x220)
exhibit a problem where, when battery capacity reporting unit is mAh,
the values being reported are wrong.  Pre-2010 and 2012 models appear
to always report in mWh and are thus unaffected.  Also, in mid-2012
Lenovo issued a BIOS update for the 2011 models that fixes the issue
(tested on x220 with a post-1.29 BIOS).  No such update is available
for the 2010 models, so those still need this patch.

Problem description: for some reason, the affected Thinkpads switch
the reporting unit between mAh and mWh; generally, mAh is used when a
laptop is plugged in and mWh when it's unplugged, although a
suspend/resume or rmmod/modprobe is needed for the switch to take
effect.  The values reported in mAh are *always* wrong.  This does
not appear to be a kernel regression; I believe that the values were
never reported correctly.  I tested back to kernel 2.6.34, with
multiple machines and BIOS versions.

Simply plugging a laptop into mains before turning it on is enough to
reproduce the problem.  Here's a sample /proc/acpi/battery/BAT0/info
from Thinkpad x220 (before a BIOS update) with a 4-cell battery:

present:                 yes
design capacity:         2886 mAh
last full capacity:      2909 mAh
battery technology:      rechargeable
design voltage:          14800 mV
design capacity warning: 145 mAh
design capacity low:     13 mAh
cycle count:              0
capacity granularity 1:  1 mAh
capacity granularity 2:  1 mAh
model number:            42T4899
serial number:           21064
battery type:            LION
OEM info:                SANYO

Once the laptop switches the unit to mWh (unplug from mains, suspend,
resume), the output changes to:

present:                 yes
design capacity:         28860 mWh

Can you see how the values for "design capacity", etc., differ by a
factor of 10 instead of 14.8 (the design voltage of this battery)?
On the battery itself it says: 14.8V, 1.95Ah, 29Wh, so clearly the
values reported in mWh are correct and the ones in mAh are not.

My guess is that this problem has been around ever since those
machines were released, but because the most common Thinkpad
batteries are rated at 10.8V, the error (8%) is small enough that it
simply hasn't been noticed or at least nobody could be bothered to
look into it.

My patch works around the problem by adjusting the incorrectly
reported mAh values by "10000 / design_voltage".  The patch also has
code to figure out if it should be activated or not.  It only
activates on Lenovo Thinkpads, only when the unit is mAh, and, as an
extra precaution, only when the battery capacity reported through
ACPI does not match what is reported through DMI (I've never
encountered a machine where the first two conditions would be true
but the last would not, but better safe than sorry).

I've been using this patch for close to a year on several systems
without any problems.

Subject: [PATCH 2098/3298] mm: fix build warning for uninitialized value

do_wp_page() sets mmun_called if mmun_start and mmun_end were
initialized and, if so, may call mmu_notifier_invalidate_range_end()
with these values.  This doesn't prevent gcc from emitting a build
warning though:

  mm/memory.c: In function `do_wp_page':
  mm/memory.c:2530: warning: `mmun_start' may be used uninitialized in this function
  mm/memory.c:2531: warning: `mmun_end' may be used uninitialized in this function

It's much easier to initialize the variables to impossible values and do
a simple comparison to determine if they were initialized to remove the
bool entirely.

Subject: [PATCH 2099/3298] memcg: oom: fix totalpages calculation for
 memory.swappiness==0

oom_badness() takes a totalpages argument which says how many pages are
available and it uses it as a base for the score calculation.  The value
is calculated by mem_cgroup_get_limit which considers both limit and
total_swap_pages (resp.  memsw portion of it).

This is usually correct but since fe35004fbf9e ("mm: avoid swapping out
with swappiness==0") we do not swap when swappiness is 0 which means
that we cannot really use up all the totalpages pages.  This in turn
confuses oom score calculation if the memcg limit is much smaller than
the available swap because the used memory (capped by the limit) is
negligible comparing to totalpages so the resulting score is too small
if adj!=0 (typically task with CAP_SYS_ADMIN or non zero oom_score_adj).
A wrong process might be selected as result.

The problem can be worked around by checking mem_cgroup_swappiness==0
and not considering swap at all in such a case.

When MEMCG is configured on (even when it's disabled by boot option),
when adding or removing a page to/from its lru list, the zone pointer
used for stats updates is nowadays taken from the struct lruvec.  (On
many configurations, calculating zone from page is slower.)

But we have no code to update all the lruvecs (per zone, per memcg) when
a memory node is hotadded.  Here's an extract from the oops which
results when running numactl to bind a program to a newly onlined node:

  BUG: unable to handle kernel NULL pointer dereference at 0000000000000f60
  IP:  __mod_zone_page_state+0x9/0x60
  Pid: 1219, comm: numactl Not tainted 3.6.0-rc5+ #180 Bochs Bochs
  Process numactl (pid: 1219, threadinfo ffff880039abc000, task ffff8800383c4ce0)
  Call Trace:
    __pagevec_lru_add_fn+0xdf/0x140
    pagevec_lru_move_fn+0xb1/0x100
    __pagevec_lru_add+0x1c/0x30
    lru_add_drain_cpu+0xa3/0x130
    lru_add_drain+0x2f/0x40
   ...

The natural solution might be to use a memcg callback whenever memory is
hotadded; but that solution has not been scoped out, and it happens that
we do have an easy location at which to update lruvec->zone.  The lruvec
pointer is discovered either by mem_cgroup_zone_lruvec() or by
mem_cgroup_page_lruvec(), and both of those do know the right zone.

So check and set lruvec->zone in those; and remove the inadequate
attempt to set lruvec->zone from lruvec_init(), which is called before
NODE_DATA(node) has been allocated in such cases.

Ah, there was one exceptionr.  For no particularly good reason,
mem_cgroup_force_empty_list() has its own code for deciding lruvec.
Change it to use the standard mem_cgroup_zone_lruvec() and
mem_cgroup_get_lru_size() too.  In fact it was already safe against such
an oops (the lru lists in danger could only be empty), but we're better
proofed against future changes this way.

I've marked this for stable (3.6) since we introduced the problem in 3.5
(now closed to stable); but I have no idea if this is the only fix
needed to get memory hotadd working with memcg in 3.6, and received no
answer when I enquired twice before.

Subject: [PATCH 2104/3298] mm: revert "mm: vmscan: scale number of pages
 reclaimed by reclaim/compaction based on failures"

Jiri Slaby reported the following:

	(It's an effective revert of "mm: vmscan: scale number of pages
	reclaimed by reclaim/compaction based on failures".) Given kswapd
	had hours of runtime in ps/top output yesterday in the morning
	and after the revert it's now 2 minutes in sum for the last 24h,
	I would say, it's gone.

The intention of the patch in question was to compensate for the loss of
lumpy reclaim.  Part of the reason lumpy reclaim worked is because it
aggressively reclaimed pages and this patch was meant to be a sane
compromise.

When compaction fails, it gets deferred and both compaction and
reclaim/compaction is deferred avoid excessive reclaim.  However, since
commit c654345924f7 ("mm: remove __GFP_NO_KSWAPD"), kswapd is woken up
each time and continues reclaiming which was not taken into account when
the patch was developed.

Attempts to address the problem ended up just changing the shape of the
problem instead of fixing it.  The release window gets closer and while
a THP allocation failing is not a major problem, kswapd chewing up a lot
of CPU is.

This patch reverts commit 83fde0f22872 ("mm: vmscan: scale number of
pages reclaimed by reclaim/compaction based on failures") and will be
revisited in the future.

Subject: [PATCH 2105/3298] mm: highmem: don't treat PKMAP_ADDR(LAST_PKMAP) as
 a highmem address

kmap_to_page returns the corresponding struct page for a virtual address
of an arbitrary mapping.  This works by checking whether the address
falls in the pkmap region and using the pkmap page tables instead of the
linear mapping if appropriate.

Unfortunately, the bounds checking means that PKMAP_ADDR(LAST_PKMAP) is
incorrectly treated as a highmem address and we can end up walking off
the end of pkmap_page_table and subsequently passing junk to pte_page.

This patch fixes the bound check to stay within the pkmap tables.

Thanks to Johannes for pointing to truncation: free_swap_and_cache()
only does a trylock on the page, so the page lock we've held since
before confirming swap is not enough to protect against truncation.

What cleanup is needed in this case? Just delete_from_swap_cache(),
which takes care of the memcg uncharge.

Subject: [PATCH 2107/3298] tmpfs: change final i_blocks BUG to WARNING

Under a particular load on one machine, I have hit shmem_evict_inode()'s
BUG_ON(inode->i_blocks), enough times to narrow it down to a particular
race between swapout and eviction.

It comes from the "if (freed > 0)" asymmetry in shmem_recalc_inode(),
and the lack of coherent locking between mapping's nrpages and shmem's
swapped count.  There's a window in shmem_writepage(), between lowering
nrpages in shmem_delete_from_page_cache() and then raising swapped
count, when the freed count appears to be +1 when it should be 0, and
then the asymmetry stops it from being corrected with -1 before hitting
the BUG.

One answer is coherent locking: using tree_lock throughout, without
info->lock; reasonable, but the raw_spin_lock in percpu_counter_add() on
used_blocks makes that messier than expected.  Another answer may be a
further effort to eliminate the weird shmem_recalc_inode() altogether,
but previous attempts at that failed.

So far undecided, but for now change the BUG_ON to WARN_ON: in usual
circumstances it remains a useful consistency check.

Subject: [PATCH 2108/3298] revert "mm: fix-up zone present pages"

Revert commit 7f1290f2f2a4 ("mm: fix-up zone present pages")

That patch tried to fix a issue when calculating zone->present_pages,
but it caused a regression on 32bit systems with HIGHMEM.  With that
change, reset_zone_present_pages() resets all zone->present_pages to
zero, and fixup_zone_present_pages() is called to recalculate
zone->present_pages when the boot allocator frees core memory pages into
buddy allocator.  Because highmem pages are not freed by bootmem
allocator, all highmem zones' present_pages becomes zero.

Various options for improving the situation are being discussed but for
now, let's return to the 3.6 code.

 value

The function is expected to return the number of bytes consumed and as long as
not all bytes have been consumed the function will be called again. Currently
the function returns 'ret', which will always be 0 in this case, so we end up in
a endless loop since the caller will assume that no bytes have been consumed. So
instead return len as it is supposed to.

Subject: [PATCH 2114/3298] drivers/iio/industrialio-event.c: eliminate
 possible double free

The function __iio_add_event_config_attrs is only called once, by the
function iio_device_register_eventset.  If the call fails,
iio_device_register_eventset calls __iio_remove_event_config_attrs.  There
is thus no need for __iio_add_event_config_attrs to also call
__iio_remove_event_config_attrs on failure.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Subject: [PATCH 2118/3298] drivers/of: Constify device_node->name and
 ->path_component_name

Neither of these should ever be changed once set. Make them const and
fix up the users that try to modify it in-place. In one case
kmalloc+memcpy is replaced with kstrdup() to avoid modifying the string.

Build tested with defconfigs on ARM, PowerPC, Sparc, MIPS, x86 among
others.

Subject: [PATCH 2121/3298] xfs: fix attr tree double split corruption

In certain circumstances, a double split of an attribute tree is
needed to insert or replace an attribute. In rare situations, this
can go wrong, leaving the attribute tree corrupted. In this case,
the attr being replaced is the last attr in a leaf node, and the
replacement is larger so doesn't fit in the same leaf node.
When we have the initial condition of a node format attribute
btree with two leaves at index 1 and 2. Call them L1 and L2.  The
leaf L1 is completely full, there is not a single byte of free space
in it. L2 is mostly empty.  The attribute being replaced - call it X
- is the last attribute in L1.

The way an attribute replace is executed is that the replacement
attribute - call it Y - is first inserted into the tree, but has an
INCOMPLETE flag set on it so that list traversals ignore it. Once
this transaction is committed, a second transaction it run to
atomically mark Y as COMPLETE and X as INCOMPLETE, so that a
traversal will now find Y and skip X. Once that transaction is
committed, attribute X is then removed.

So, the initial condition is:

     +--------+     +--------+
     |   L1   |     |   L2   |
     | fwd: 2 |---->| fwd: 0 |
     | bwd: 0 |<----| bwd: 1 |
     | fsp: 0 |     | fsp: N |
     |--------|     |--------|
     | attr A |     | attr 1 |
     |--------|     |--------|
     | attr B |     | attr 2 |
     |--------|     |--------|
     ..........     ..........
     |--------|     |--------|
     | attr X |     | attr n |
     +--------+     +--------+

So now we go to replace X, and see that L1:fsp = 0 - it is full so
we can't insert Y in the same leaf. So we record the the location of
attribute X so we can track it for later use, then we split L1 into
L1 and L3 and reblance across the two leafs. We end with:

     +--------+     +--------+     +--------+
     |   L1   |     |   L3   |     |   L2   |
     | fwd: 3 |---->| fwd: 2 |---->| fwd: 0 |
     | bwd: 0 |<----| bwd: 1 |<----| bwd: 3 |
     | fsp: M |     | fsp: J |     | fsp: N |
     |--------|     |--------|     |--------|
     | attr A |     | attr X |     | attr 1 |
     |--------|     +--------+     |--------|
     | attr B |                    | attr 2 |
     |--------|                    |--------|
     ..........                    ..........
     |--------|                    |--------|
     | attr W |                    | attr n |
     +--------+                    +--------+

And we track that the original attribute is now at L3:0.

We then try to insert Y into L1 again, and find that there isn't
enough room because the new attribute is larger than the old one.
Hence we have to split again to make room for Y. We end up with
this:

     +--------+     +--------+     +--------+     +--------+
     |   L1   |     |   L4   |     |   L3   |     |   L2   |
     | fwd: 4 |---->| fwd: 3 |---->| fwd: 2 |---->| fwd: 0 |
     | bwd: 0 |<----| bwd: 1 |<----| bwd: 4 |<----| bwd: 3 |
     | fsp: M |     | fsp: J |     | fsp: J |     | fsp: N |
     |--------|     |--------|     |--------|     |--------|
     | attr A |     | attr Y |     | attr X |     | attr 1 |
     |--------|     + INCOMP +     +--------+     |--------|
     | attr B |     +--------+                    | attr 2 |
     |--------|                                   |--------|
     ..........                                   ..........
     |--------|                                   |--------|
     | attr W |                                   | attr n |
     +--------+                                   +--------+

And now we have the new (incomplete) attribute @ L4:0, and the
original attribute at L3:0. At this point, the first transaction is
committed, and we move to the flipping of the flags.

This is where we are supposed to end up with this:

     +--------+     +--------+     +--------+     +--------+
     |   L1   |     |   L4   |     |   L3   |     |   L2   |
     | fwd: 4 |---->| fwd: 3 |---->| fwd: 2 |---->| fwd: 0 |
     | bwd: 0 |<----| bwd: 1 |<----| bwd: 4 |<----| bwd: 3 |
     | fsp: M |     | fsp: J |     | fsp: J |     | fsp: N |
     |--------|     |--------|     |--------|     |--------|
     | attr A |     | attr Y |     | attr X |     | attr 1 |
     |--------|     +--------+     + INCOMP +     |--------|
     | attr B |                    +--------+     | attr 2 |
     |--------|                                   |--------|
     ..........                                   ..........
     |--------|                                   |--------|
     | attr W |                                   | attr n |
     +--------+                                   +--------+

But that doesn't happen properly - the attribute tracking indexes
are not pointing to the right locations. What we end up with is both
the old attribute to be removed pointing at L4:0 and the new
attribute at L4:1.  On a debug kernel, this assert fails like so:

XFS: Assertion failed: args->index2 < be16_to_cpu(leaf2->hdr.count), file: fs/xfs/xfs_attr_leaf.c, line: 2725

because the new attribute location does not exist. On a production
kernel, this goes unnoticed and the code proceeds ahead merrily and
removes L4 because it thinks that is the block that is no longer
needed. This leaves the hash index node pointing to entries
L1, L4 and L2, but only blocks L1, L3 and L2 to exist. Further, the
leaf level sibling list is L1 <-> L4 <-> L2, but L4 is now free
space, and so everything is busted. This corruption is caused by the
removal of the old attribute triggering a join - it joins everything
correctly but then frees the wrong block.

xfs_repair will report something like:

bad sibling back pointer for block 4 in attribute fork for inode 131
problem with attribute contents in inode 131
would clear attr fork
bad nblocks 8 for inode 131, would reset to 3
bad anextents 4 for inode 131, would reset to 0

The problem lies in the assignment of the old/new blocks for
tracking purposes when the double leaf split occurs. The first split
tries to place the new attribute inside the current leaf (i.e.
"inleaf == true") and moves the old attribute (X) to the new block.
This sets up the old block/index to L1:X, and newly allocated
block to L3:0. It then moves attr X to the new block and tries to
insert attr Y at the old index. That fails, so it splits again.

With the second split, the rebalance ends up placing the new attr in
the second new block - L4:0 - and this is where the code goes wrong.
What is does is it sets both the new and old block index to the
second new block. Hence it inserts attr Y at the right place (L4:0)
but overwrites the current location of the attr to replace that is
held in the new block index (currently L3:0). It over writes it with
L4:1 - the index we later assert fail on.

Hopefully this table will show this in a foramt that is a bit easier
to understand:

Split		old attr index		new attr index
		vanilla	patched		vanilla	patched
before 1st	L1:26	L1:26		N/A	N/A
after 1st	L3:0	L3:0		L1:26	L1:26
after 2nd	L4:0	L3:0		L4:1	L4:0
                ^^^^			^^^^
		wrong			wrong

The fix is surprisingly simple, for all this analysis - just stop
the rebalance on the out-of leaf case from overwriting the new attr
index - it's already correct for the double split case.

Subject: [PATCH 2122/3298] xfs: fix broken error handling in xfs_vm_writepage

When we shut down the filesystem, it might first be detected in
writeback when we are allocating a inode size transaction. This
happens after we have moved all the pages into the writeback state
and unlocked them. Unfortunately, if we fail to set up the
transaction we then abort writeback and try to invalidate the
current page. This then triggers are BUG() in block_invalidatepage()
because we are trying to invalidate an unlocked page.

Fixing this is a bit of a chicken and egg problem - we can't
allocate the transaction until we've clustered all the pages into
the IO and we know the size of it (i.e. whether the last block of
the IO is beyond the current EOF or not). However, we don't want to
hold pages locked for long periods of time, especially while we lock
other pages to cluster them into the write.

To fix this, we need to make a clear delineation in writeback where
errors can only be handled by IO completion processing. That is,
once we have marked a page for writeback and unlocked it, we have to
report errors via IO completion because we've already started the
IO. We may not have submitted any IO, but we've changed the page
state to indicate that it is under IO so we must now use the IO
completion path to report errors.

To do this, add an error field to xfs_submit_ioend() to pass it the
error that occurred during the building on the ioend chain. When
this is non-zero, mark each ioend with the error and call
xfs_finish_ioend() directly rather than building bios. This will
immediately push the ioends through completion processing with the
error that has occurred.

Subject: [PATCH 2123/3298] xfs: drop buffer io reference when a bad bio is
 built

Error handling in xfs_buf_ioapply_map() does not handle IO reference
counts correctly. We increment the b_io_remaining count before
building the bio, but then fail to decrement it in the failure case.
This leads to the buffer never running IO completion and releasing
the reference that the IO holds, so at unmount we can leak the
buffer. This leak is captured by this assert failure during unmount:

XFS: Assertion failed: atomic_read(&pag->pag_ref) == 0, file: fs/xfs/xfs_mount.c, line: 273

This is not a new bug - the b_io_remaining accounting has had this
problem for a long, long time - it's just very hard to get a
zero length bio being built by this code...

Further, the buffer IO error can be overwritten on a multi-segment
buffer by subsequent bio completions for partial sections of the
buffer. Hence we should only set the buffer error status if the
buffer is not already carrying an error status. This ensures that a
partial IO error on a multi-segment buffer will not be lost. This
part of the problem is a regression, however.

For probing via device tree, we need to support the case without platform_data.
In this case, chip.base is set to -1 for automatic numbering.

The driver has both SPI and I2C pieces. The appropriate pieces are built based
on whether SPI and/or I2C is/are enabled. However, it was only checking if I2C
was built-in, never if it was built as a module. This patch checks for either
since building both this driver and I2C as modules is possible.

SPEAr platform provides a provision to control chipselects of ARM PL022
Prime Cell spi controller through its system registers, which otherwise

This commit intends to provide the spi chipselect control in software over
gpiolib interface. spi chip drivers can use the exported gpiolib interface to
define their chipselect through DT or platform data.

+=== ST Microelectronics SPEAr SPI CS Driver ===
+
+SPEAr platform provides a provision to control chipselects of ARM PL022 Prime
+Cell spi controller through its system registers, which otherwise remains under
+PL022 control. If chipselect remain under PL022 control then they would be
+released as soon as transfer is over and TxFIFO becomes empty. This is not
+desired by some of the device protocols above spi which expect (multiple)
+transfers without releasing their chipselects.
+
+Chipselects can be controlled by software by turning them as GPIOs. SPEAr
+provides another interface through system registers through which software can
+directly control each PL022 chipselect. Hence, it is natural for SPEAr to export
+the control of this interface as gpio.
+
+Required properties:
+
+  * compatible: should be defined as "st,spear-spics-gpio"
+  * reg: mentioning address range of spics controller
+  * st-spics,peripcfg-reg: peripheral configuration register offset
+  * st-spics,sw-enable-bit: bit offset to enable sw control
+  * st-spics,cs-value-bit: bit offset to drive chipselect low or high
+  * st-spics,cs-enable-mask: chip select number bit mask
+  * st-spics,cs-enable-shift: chip select number program offset
+  * gpio-controller: Marks the device node as gpio controller
+  * #gpio-cells: should be 1 and will mention chip select number
+
+All the above bit offsets are within peripcfg register.
+
+Example:
+-------
+spics: spics@e0700000{
+        compatible = "st,spear-spics-gpio";
+        reg = <0xe0700000 0x1000>;
+        st-spics,peripcfg-reg = <0x3b0>;
+        st-spics,sw-enable-bit = <12>;
+        st-spics,cs-value-bit = <11>;
+        st-spics,cs-enable-mask = <3>;
+        st-spics,cs-enable-shift = <8>;
+        gpio-controller;
+        #gpio-cells = <2>;
+};
+
+
+spi0: spi@e0100000 {
+        status = "okay";
+        num-cs = <3>;
+        cs-gpios = <&gpio1 7 0>, <&spics 0>,
+                   <&spics 1>;

Subject: [PATCH 2134/3298] m68k: fix sigset_t accessor functions

The sigaddset/sigdelset/sigismember functions that are implemented with
bitfield insn cannot allow the sigset argument to be placed in a data
register since the sigset is wider than 32 bits.  Remove the "d"
constraint from the asm statements.

The effect of the bug is that sending RT signals does not work, the signal
number is truncated modulo 32.

Subject: [PATCH 2136/3298] ALSA: ua101, usx2y: fix broken MIDI output

Commit 88a8516a2128 (ALSA: usbaudio: implement USB autosuspend) added
autosuspend code to all files making up the snd-usb-audio driver.
However, midi.c is part of snd-usb-lib and is also used by other
drivers, not all of which support autosuspend.  Thus, calls to
usb_autopm_get_interface() could fail, and this unexpected error would
result in the MIDI output being completely unusable.

Make it work by ignoring the error that is expected with drivers that do
not support autosuspend.

Subject: [PATCH 2137/3298] fanotify: fix FAN_Q_OVERFLOW case of
 fanotify_read()

If the FAN_Q_OVERFLOW bit set in event->mask, the fanotify event
metadata will not contain a valid file descriptor, but
copy_event_to_user() didn't check for that, and unconditionally does a
fd_install() on the file descriptor.

Which in turn will cause a BUG_ON() in __fd_install().

Introduced by commit 352e3b249284 ("fanotify: sanitize failure exits in
copy_event_to_user()")

Mea culpa - missed that path ;-/

Subject: [PATCH 2144/3298] drm/nouveau/bios: fix DCB v1.5 parsing

memcmp->nv_strncmp conversion, in addition to name change, should have
inverted the return value.

But nv_strncmp does not act like strncmp - it does not check for string
terminator, returns true/false instead of -1/0/1 and has different
parameters order.

Let's rename it to nv_memcmp and let it act like memcmp.

Subject: [PATCH 2147/3298] sis900: fix sis900_set_mode call parameters.

Leftover of 57d6d456cfb89264f87d24f52640ede23fdf12bd ("sis900: stop
using net_device.{base_addr, irq} and convert to __iomem.").

It is needed for suspend / resume to work.

Subject: [PATCH 2157/3298] sparc64: not any error from do_sigaltstack() should
 fail rt_sigreturn()

If a signal handler is executed on altstack and another signal comes,
we will end up with rt_sigreturn() on return from the second handler
getting -EPERM from do_sigaltstack().  It's perfectly OK, since we
are not asking to change the settings; in fact, they couldn't have been
changed during the second handler execution exactly because we'd been
on altstack all along.  64bit sigreturn on sparc treats any error from
do_sigaltstack() as "SIGSEGV now"; we need to switch to the same semantics
we are using on other architectures.

 correct minor

When doing conversion to dynamic input numbers I inadvertently moved
/dev/input/mice from c,13,63 to c,13,31. We need to fix this so that
setups with statically populated /dev continue working.

Subject: [PATCH 2159/3298] ARM: davinci: dm644x: fix out range signal for ED

Fix the video clock setting when custom timings are used with
pclock <= 27MHz. Existing video clock selection uses PLL2 mode
which results in a 54MHz clock whereas using the MXI mode results
in a 27MHz clock (which is the one actually desired).

This bug affects the Enhanced Definition (ED) support on DM644x.
Without this patch, out-range signals errors are were observed on
the TV when viewing ED. An out-of-range signal is often caused when
the field rate is above the rate that the television will handle.

Subject: [PATCH 2160/3298] OMAPFB: Fix possible null pointer dereferencing

Commit 952cbaaa9b8beacc425f9aedf370468cbb737a2c (OMAPFB: Change
dssdev->manager references) added checks for OMAPFB_WAITFORVSYNC ioctl
to verify that the display, output and overlay manager exist. However,
the code erroneously uses && for each part, which means that
OMAPFB_WAITFORVSYNC may crash the kernel if no display, output or
manager is associated with the framebuffer.

This patch fixes the issue by using ||.

Subject: [PATCH 2163/3298] ALSA: hda - Fix recursive suspend/resume call

When the bus reset is performed during the suspend/resume (including
the power-saving too), it calls snd_hda_suspend() and
snd_hda_resume() again, and deadlocks eventually.

For avoiding the recursive call, add a new flag indicating that the PM
is being performed, and don't go to the bus reset mode when it's on.

Subject: [PATCH 2165/3298] vtime: Remove the underscore prefix invasion

Prepending irq-unsafe vtime APIs with underscores was actually
a bad idea as the result is a big mess in the API namespace that
is even waiting to be further extended. Also these helpers
are always called from irq safe callers except kvm. Just
provide a vtime_account_system_irqsafe() for this specific
case so that we can remove the underscore prefix on other
vtime functions.

Subject: [PATCH 2167/3298] vtime: Consolidate a bit the ctx switch code

On ia64 and powerpc, vtime context switch only consists
in flushing system and user pending time, plus a few
arch housekeeping.

Consolidate that into a generic implementation. s390 is
a special case because pending user and system time accounting
there is hard to dissociate. So it's keeping its own implementation.

Subject: [PATCH 2168/3298] vtime: No need to disable irqs on vtime_account()

vtime_account() is only called from irq entry. irqs
are always disabled at this point so we can safely
remove the irq disabling guards on that function.

Subject: [PATCH 2176/3298] ALSA: hda - Limit runtime PM support only to known
 Intel chips

We've got a report that the runtime PM may make the codec the
unresponsive on AMD platforms.  Since the feature has been tested only
on the recent Intel platforms, it's safer to limit the support to such
devices for now.

This patch adds a new DCAPS bit flag indicating the runtime PM
support, and mark it for Intel controllers.

Calls into reiserfs journalling code and reiserfs_get_block() need to
be protected with write lock. We remove write lock around calls to high

Subject: [PATCH 2181/3298] ext3: Avoid underflow of in ext3_trim_fs()

Currently if len argument in ext3_trim_fs() is smaller than one block,
the 'end' variable underflow. Avoid that by returning EINVAL if len is
smaller than file system block.

Also remove useless unlikely().

Subject: [PATCH 2182/3298] tools: Define a Makefile function to do subdir
 processing

Define a Makefile function that can be called with $(call ...) to wrap
the subdir make invocations in tools/Makefile.

This will allow us in the next patch to insert bits in there to honour
O= flags when called from the top-level Makefile.

Subject: [PATCH 2183/3298] tools: Honour the O= flag when tool build called
 from a higher Makefile

Honour the O= flag that was passed to a higher level Makefile and then passed
down as part of a tool build.

To make this work, the top-level Makefile passes the original O= flag and
subdir=tools to the tools/Makefile, and that in turn passes
subdir=$(O)/$(subdir)/foodir when building tool foo in directory
$(O)/$(subdir)/foodir (where the intervening slashes aren't added if an
element is missing).

For example, take perf.  This is found in tools/perf/.  Assume we're building
into directory ~/zebra/, so we pass O=~/zebra to make.  Dependening on where
we run the build from, we see:

	make run in dir		$(OUTPUT) dir
	=======================	==================
	linux			~/zebra/tools/perf/
	linux/tools		~/zebra/perf/
	linux/tools/perf	~/zebra/

and if O= is not set, we get:

	make run in dir		$(OUTPUT) dir
	=======================	==================
	linux			linux/tools/perf/
	linux/tools		linux/tools/perf/
	linux/tools/perf	linux/tools/perf/

The output directories are created by the descend function if they don't
already exist.

Subject: [PATCH 2186/3298] perf: Make perf build for x86 with UAPI
 disintegration applied

Make perf build for x86 once the UAPI disintegration patches for that arch
have been applied by adding the appropriate -I flags - in the right order -
and then converting some #includes that use ../.. notation to find main kernel
headerfiles to use <asm/foo.h> and <linux/foo.h> instead.

Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include.
This makes sure we get the userspace version of the pt_regs struct.  Ideally,
we wouldn't have the latter -I flag at all, but unfortunately we want
asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI -
at least not for x86.  I wonder if the bits outside of the __KERNEL__ guards
*should* be transferred there.

I note also that perf seems to do its dependency handling manually by listing
all the header files it might want to use in LIB_H in the Makefile.  Can this
be changed to use -MD?

Note that to do make this work, we need to export and UAPI disintegrate
linux/hw_breakpoint.h, which I think should've been exported previously so that
perf can access the bits.  We have to do this in the same patch to maintain
bisectability.

We had assigned the return value to 'ret' but ignored it when
return from isl29018_write_raw(), it's better to return 'ret'
instead of 0.

Subject: [PATCH 2189/3298] staging:iio: Add common ADIS library

A lot of the devices from the ADIS family use the same methods for accessing
registers, sampling data and trigger handling. They also have similar register
layout for the control registers.

This patch adds a common library for these devices. The library implements
functions for reading and writing registers as buffer and trigger management. It
also provides a set functions for accessing the control registers and for
running the devices internal self-test. Having this common library code will
allow us to remove a lot of duplicated code.

Subject: [PATCH 2190/3298] staging:iio:adis16201: Use adis library

Use the new adis library for the adis16201 driver. This allows us to completely
scrap the adis16201 buffer and trigger code and more than half of the core
driver code.

Subject: [PATCH 2191/3298] staging:iio:adis16203: Use adis library

Use the new adis library for the adis16203 driver. This allows us to completely
scrap the adis16203 buffer and trigger code and more than half of the core
driver code.

From 5bd22f516e43617edc80c56c9e4c44426aa36a2f Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen <lars@metafoo.de>
Date: Tue, 13 Nov 2012 13:28:00 +0000
Subject: [PATCH 2192/3298] staging:iio:adis16204: Use adis library

Use the new adis library for the adis16204 driver. This allows us to completely
scrap the adis16204 buffer and trigger code and more than half of the core
driver code.

From 511fb29e351ae90b0ad7341f3729468003449ac4 Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen <lars@metafoo.de>
Date: Tue, 13 Nov 2012 13:28:00 +0000
Subject: [PATCH 2193/3298] staging:iio:adis16209: Use adis library

Use the new adis library for the adis16209 driver. This allows us to completely
scrap the adis16209 buffer and trigger code and more than half of the core
driver code.

From edcf600912d218a1d8a6378e37b19ecab63abddd Mon Sep 17 00:00:00 2001

Subject: [PATCH 2194/3298] staging:iio:adis16220: Use adis library

Use the new adis library for the adis16220 driver. The adis16220 driver is a bit
special and so we can only make use of the generic register access and control
functions for now.

Subject: [PATCH 2195/3298] staging:iio:adis16240: Use adis library

Use the new adis library for the adis16240 driver. This allows us to completely
scrap the adis16240 buffer and trigger code and more than half of the core
driver code.

From 9d5e9fdf0f8846e014125f8e57fe5f3e03c8839f Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen <lars@metafoo.de>
Date: Tue, 13 Nov 2012 13:28:00 +0000
Subject: [PATCH 2196/3298] staging:iio:adis16260: Use adis library

Use the new adis library for the adis16260 driver. This allows us to completely
scrap the adis16260 buffer and trigger code and about half of the core driver
code.

From a458c55c107c5e467ab5b7e471f77ec5868afcb9 Mon Sep 17 00:00:00 2001
From: Lars-Peter Clausen <lars@metafoo.de>
Date: Tue, 13 Nov 2012 13:28:00 +0000
Subject: [PATCH 2197/3298] staging:iio:adis_lib: Use triggered buffer setup
 helper function

Use the triggered buffer helper functions to setup and tear down the buffer for
the adis library instead of doing this manually. This also means that we switch
away from the deprecated sw_ring buffer and use the kfifo buffer now instead.

Subject: [PATCH 2198/3298] staging:iio:adis: Preallocate transfer message

Currently the driver reads out all sample registers of the device and throws
away those which it does not need. Furthermore the SPI message is constructed
each time the trigger handler is run, although it will be the same each time.
This patch preallocates and pre-constructs the SPI message in the
"update_scan_mode" callback. Only those register which are actually selected for
sampling are included in the message. The patch also gets rid of the conversion
of the sample data from big endian to the native endianness and instead marks
the channel as big endian in its scan type. This allows to directly push the
SPI transfer buffer to the IIO buffer without the need to post-process it.

Subject: [PATCH 2199/3298] staging:iio: Move adis library out of staging

Now that the adis library no longer depends on the sw_ring buffer implementation
we can move it out of staging.

While we are at it also sort the entries in the iio Kconfig and Makefile to be
in alphabetical order.

Subject: [PATCH 2200/3298] staging:iio:ad7298: Do not perform endianness
 conversion in buffered mode

For buffered mode we do not want to perform endianness conversion in the kernel,
but rather offload it to user space, since it is not always required to do a
conversion at all. It also greatly simplifies the kernel code since no
post-processing has to be done and may allow future optimizations like streaming
data directly to a storage device or over the network via DMA.

Rework the regulator handling of the driver to match more closely what we do in

Also dispose the option of specifying the reference voltage via platform data.

Subject: [PATCH 2202/3298] staging:iio:ad7298: Fix temperature scale and
 offset

The temperature scale and offset depend on the reference voltage, the current
formula used in the driver assumes a 2.5V reference. This patch modifies the
code to report the unprocessed value for the temperature channel "raw" property
and to provide proper "scale" and "offset" properties which depend on the
selected reference voltage.

Subject: [PATCH 2203/3298] staging:iio:ad7298: Squash everything into one file

The recent cleanups have decimated the drivers code size by quite a bit. It is
only a few hundred lines in total now. Putting everything into one file also
allows to reduce the code size a bit more by removing a few lines of boilerplate
code. The only functional change made by this patch is that we now always
include buffer support, instead of making it optional. This is more consistent
with what we do for other drivers.

Subject: [PATCH 2204/3298] staging:iio: Move the ad7298 driver out of staging

The driver does not expose any custom API to userspace and none of the standard
static code checker tools report any issues, so move it out of staging.

Subject: [PATCH 2207/3298] NFC: pn533: Fix use after free

cmd was freed in pn533_dep_link_up regardless of
pn533_send_cmd_frame_async return code. Cmd is passed as argument to
pn533_in_dep_link_up_complete callback and should be freed there.

Subject: [PATCH 2212/3298] md: make sure everything is freed when dm-raid
 stops an array.

md_stop() would stop an array, but not free various attached
data structures.
For internal arrays, these are freed later in do_md_stop() or
mddev_put(), but they don't apply for dm-raid arrays.
So get md_stop() to free them, and only all it from dm-raid.
For internal arrays we now call __md_stop.

Subject: [PATCH 2213/3298] of/net/mdio-gpio: Fix pdev->id issue when using
 devicetrees.

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"

Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.

Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.

So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

Subject: [PATCH 2216/3298] PM / devfreq: Add sysfs node to expose available
 frequencies

devfreq governors such as ondemand are controlled by a min and
max frequency, while governors like userspace governor allow us
to set a specific frequency.
However, for the same specific device, depending on the SoC, the
available frequencies can vary.

So expose the available frequencies as a snapshot over sysfs to
allow informed decisions.

This was inspired by cpufreq framework's equivalent for similar
usage sysfs node: scaling_available_frequencies.

Subject: [PATCH 2222/3298] PM / devfreq: map devfreq drivers to governor using
 name

Allow devfreq drivers to register a preferred governor name
and when the devfreq governor loads itself at a later point
required drivers are managed appropriately, at the time of
unload of a devfreq governor, stop managing those drivers
as well.

Since the governor structures do not need to be exposed
anymore, remove the definitions and make them static

NOTE: devfreq_list_lock is now used to protect governor
start and stop - as this allows us to protect governors and
devfreq with the proper dependencies as needed.

As part of this change, change the registration of exynos
bus driver to request for ondemand using the governor name.

Subject: [PATCH 2223/3298] PM / devfreq: governors: add GPL module license and
 allow module build

Add GPL module license and remove the static build
restrictions for building governors. This allows governors now
to be loaded on a need basis and reloaded independently of kernel
build

Subject: [PATCH 2224/3298] PM / devfreq: allow sysfs governor node to switch
 governor

This allows us to select governor runtime from the
default configuration without having to rebuild kernel
or the devfreq driver using the sysfs node:
/sys/class/devfreq/.../governor
cat of the governor will return valid governor
and an echo 'governor_name'>governor will switch
governor

Subject: [PATCH 2227/3298] mfd: twl-core: Fix chip ID for the twl6030-pwm
 module

The correct chip id is 1 since the PWM module is on address 0x49. With the
current TWL6030_MODULE_ID1 the kernel will crash early since we have:

 #define TWL6030_MODULE_ID1 0x0E
and
 static struct twl_client twl_modules[4];

Down in the stack we try to get the module by:
struct twl_client	*twl = &twl_modules[chip];

Which is obviously going to do nasty things.

 Exynos4210 SOC

Commit 8214513 ("ARM: EXYNOS: fix address for EXYNOS4 MDMA1")
changed EXYNOS specific setup of PL330 DMA engine to use 'non-secure'
mdma1 address instead of 'secure' one (from 0x12840000 to 0x12850000)
to fix issue with some Exynos4212 SOCs.  Unfortunately it brakes
PL330 setup for revision 0 of Exynos4210 SOC (mdma1 device cannot
be found at 'non-secure' address):

[    0.566245] dma-pl330 dma-pl330.2: PERIPH_ID 0x0, PCELL_ID 0x0 !
[    0.566278] dma-pl330: probe of dma-pl330.2 failed with error -22

Fix it by using 'secure' mdma1 address on Exynos4210 revision 0 SOC.

This patch synchronises the register cache after the reset to preserve
any register changes that had been applied.

Subject: [PATCH 2236/3298] vtime: Warn if irqs aren't disabled on system time
 accounting APIs

System time accounting APIs such as vtime_account_system() and
vtime_account_idle() need to be irqsafe. Current callers include
irq entry, exit and kvm, all of which have been checked against that
requirement. Now it's better to grow that with an automatic check
in case we have further callers or we missed something.

After the recent pile of disable-cloning patches, e.g.

commit e3b86d6941c7e5f90be05d986fce1fcb40c68d6b
Author: Egbert Eich <eich@suse.de>
Date:   Sat Oct 13 14:30:15 2012 +0200

    DRM/i915: Don't clone SDVO LVDS with analog

and a bug report from Chris Wilson indicating that cloning doesn't
even work for DVI-SDVO and native VGA, let's just disable cloning on
sdvo encoders completely.

v2: Update the comment in the code as discussed with Paulo Zanoni.

Subject: [PATCH 2239/3298] radeon: add AGPMode 1 quirk for RV250

The Intel 82855PM host bridge / Mobility FireGL 9000 RV250 combination
in an (outdated) ThinkPad T41 needs AGPMode 1 for suspend/resume (under
KMS, that is). So add a quirk for it.

(Change R250 to RV250 in comment for preceding quirk too.)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In case of error, inet6_csk_update_pmtu() should consistently
return NULL.

Bug added in commit 35ad9b9cf7d8a
(ipv6: Add helper inet6_csk_update_pmtu().)

reloc.

Commit 71c6c837 (drivers/net: fix tasklet misuse issue) introduced a
build failure in the xilinx driver. axienet_dma_err_handler isn't
declared before its use in axienet_open.

This patch provides the prototype before axienet_open.

Subject: [PATCH 2249/3298] x86, efi: Fix processor-specific memcpy() build
 error

Building for Athlon/Duron/K7 results in the following build error,

arch/x86/boot/compressed/eboot.o: In function `__constant_memcpy3d':
eboot.c:(.text+0x385): undefined reference to `_mmx_memcpy'
arch/x86/boot/compressed/eboot.o: In function `efi_main':
eboot.c:(.text+0x1a22): undefined reference to `_mmx_memcpy'

because the boot stub code doesn't link with the kernel proper, and
therefore doesn't have access to the 3DNow version of memcpy. So,
follow the example of misc.c and #undef memcpy so that we use the
version provided by misc.c.

See https://bugzilla.kernel.org/show_bug.cgi?id=50391

Subject: [PATCH 2251/3298] iio:imu:adis: Add paging support

Some of the newer generation devices from the ADIS16XXX series have more
registers than what can be supported with the current register addressing
scheme. These devices implement register paging to support a larger register
range. Each page is 128 registers large and the currently active page can be
selected via register 0x00 in each page. This patch implements transparent
paging inside the common adis library. The register read/write interface stays
the same and when a register is accessed the library automatically switches to
the correct page if it is not already selected. The page number is encoded in
the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

Subject: [PATCH 2253/3298] iio: Factor out fixed point number parsing into its
 own function

Factor out the code for parsing fixed point numbers into its own function and
make this function globally available. This allows us to reuse the code to parse
fixed point numbers in individual IIO drivers.

Subject: [PATCH 2255/3298] ACPI: Allow ACPI handles of devices to be
 initialized in advance

Currently, the ACPI handles of devices are initialized from within
device_add(), by acpi_bind_one() called from acpi_platform_notify()
which first uses the .find_device() routine provided by the device's
bus type to find the matching device node in the ACPI namespace.
This is a source of some computational overhead and, moreover, the
correctness of the result depends on the implementation of
.find_device() which is known to fail occasionally for some bus types
(e.g. PCI).  In some cases, however, the corresponding ACPI device
node is known already before calling device_add() for the given
struct device object and the whole .find_device() dance in
acpi_platform_notify() is then simply unnecessary.

For this reason, make it possible to initialize the ACPI handles of
devices before calling device_add() for them.  Modify
acpi_platform_notify() to call acpi_bind_one() in advance to check
the device's existing ACPI handle and skip the .find_device()
search if that is successful.  Change acpi_bind_one() accordingly.

Subject: [PATCH 2256/3298] ACPI / driver core: Introduce struct acpi_dev_node
 and related macros

To avoid adding an ACPI handle pointer to struct device on
architectures that don't use ACPI, or generally when CONFIG_ACPI is
not set, in which cases that pointer is useless, define struct
acpi_dev_node that will contain the handle pointer if CONFIG_ACPI is
set and will be empty otherwise and use it to represent the ACPI
device node field in struct device.

In addition to that define macros for reading and setting the ACPI
handle of a device that don't generate code when CONFIG_ACPI is
unset.  Modify the ACPI subsystem to use those macros instead of
referring to the given device's ACPI handle directly.

Subject: [PATCH 2257/3298] ACPI / platform: Initialize ACPI handles of
 platform devices in advance

The current platform device creation and registration code in
acpi_create_platform_device() is quite convoluted.  This function
takes an ACPI device node as an argument and eventually calls
platform_device_register_resndata() to create and register a
platform device object on the basis of the information contained
in that code.  However, it doesn't associate the new platform
device with the ACPI node directly, but instead it relies on
acpi_platform_notify(), called from within device_add(), to find
that ACPI node again with the help of acpi_platform_find_device()
and acpi_platform_match() and then attach the new platform device
to it.  This causes an additional ACPI namespace walk to happen and
is clearly suboptimal.

Use the observation that it is now possible to initialize the ACPI
handle of a device before calling device_add() for it to make this
code more straightforward.  Namely, add a new field to struct
platform_device_info allowing us to pass the ACPI handle of interest
to platform_device_register_full(), which will then use it to
initialize the new device's ACPI handle before registering it.
This will cause acpi_platform_notify() to use the ACPI handle from
the device structure directly instead of using the .find_device()
routine provided by the device's bus type.  In consequence,
acpi_platform_bus, acpi_platform_find_device(), and
acpi_platform_match() are not necessary any more, so remove them.

You can not use virt_to_phys() on the address returned from
dma_alloc_coherent(); it may not be part of the kernel direct-mapped

 on error

Ignoring the real cause of the interrupt is not a good idea; this
behaviour has been observed to bring Dove platforms to silently
lockup.  Instead, on error fall through to the normal interrupt
processing.

This is especially important on Dove platforms as errors are
handled separately, and allows us to clear down the real cause of
the interrupt.

Subject: [PATCH 2264/3298] ASoC: kirkwood-i2s: fix DMA underruns

Stress testing the driver with multiple start/stop events causes
kirkwood-dma to report underrun errors (which used to cause the kernel
to lock up solidly).  This is because kirkwood-i2s is not respecting
the restrictions imposed on clearing the 'pause' bit.  Follow what the
spec says; the busy bit must be read as being clear twice before the
pause bit can be released.  This solves the underruns.

However, it has been noticed that the busy bit occasionally does not
clear itself, hence the waiting is bounded to 5ms maximum to avoid a
new reason for the kernel to lockup.

Subject: [PATCH 2265/3298] ASoC: kirkwood-i2s: more pause-mode fixes

Don't even momentarily set the pause status when starting the channel;
if we do, we should check the busy bit to ensure that we comply with
the spec.  In any case, it isn't necessary; we will not active on a
START event so there is no need to pause the DMA.

Subject: [PATCH 2266/3298] xen/privcmd: Correctly return success from
 IOCTL_PRIVCMD_MMAPBATCH

This is a regression introduced by ceb90fa0 (xen/privcmd: add
PRIVCMD_MMAPBATCH_V2 ioctl).  It broke xentrace as it used
xc_map_foreign() instead of xc_map_foreign_bulk().

Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious
that it broke. The return value is set early on to -EINVAL, and if all
goes well, the "set top bits of the MFN's" never gets called, so the
return value is still EINVAL when the function gets to the end, causing
the caller to think it went wrong (which it didn't!)

Now also including Andres "move the ret = -EINVAL into the error handling
path, as this avoids other similar errors in future.

Commit 509b7455 (of/fdt: Don't copy garbage after "/" in root node path)
sets the path length to 0 to ignore any garbage after "/" in the root
node path. This has the side effect of also ignoring '\0' at the end of
the root node path. This patch sets the ignores the garbage by setting
the last character to '\0' and length to 1.

Subject: [PATCH 2273/3298] of: introduce for_each_matching_node_and_match()

The following pattern of code is tempting:

    for_each_matching_node(np, table) {
        match = of_match_node(table, np);

However, this results in iterating over table twice; the second time
inside of_match_node(). The implementation of for_each_matching_node()
already found the match, so this is redundant. Invent new function
of_find_matching_node_and_match() and macro
for_each_matching_node_and_match() to remove the double iteration,
thus transforming the above code to:

    for_each_matching_node_and_match(np, table, &match)

Subject: [PATCH 2274/3298] x86-32: Fix invalid stack address while in softirq

In 32 bit the stack address provided by kernel_stack_pointer() may
point to an invalid range causing NULL pointer access or page faults
while in NMI (see trace below). This happens if called in softirq
context and if the stack is empty. The address at &regs->sp is then
out of range.

Fixing this by checking if regs and &regs->sp are in the same stack
context. Otherwise return the previous stack pointer stored in struct
thread_info. If that address is invalid too, return address of regs.

In order to cover the full code ranges, the CFI directive must be
first, though.

Subject: [PATCH 2278/3298] gpiolib: let gpiochip_add_pin_range() specify
 offset

Like with commit 3c739ad0df5eb41cd7adad879eda6aa09879eb76
it is not always enough to specify all the pins of a gpio_chip
from offset zero to be added to a pin map range, since the
mapping from GPIO to pin controller may not be linear at all,
but need to be broken into a few consecutive sub-ranges or
1-pin entries for complicated cases. The ranges may also be
sparse.

This alters the signature of the function to accept offsets
into both the GPIO-chip local pinspace and the pin controller
local pinspace.

This adds a function to the pinctrl core to retrieve the GPIO
range associated with a certain pin for a certain controller.
This is needed when a pinctrl driver want to look up the
corresponding struct gpio_chip for a certain pin. As the
GPIO drivers can now create these ranges themselves, the
pinctrl driver no longer knows about all its associated GPIO
chips.

platform data, now let the GPIO chip driver register it's own
ranges and have the pinctrl driver look up the GPIO chip from
the pinctrl core as necessary.

we have these two mechanisms broken apart now, and they can
each probe in isolation. If the GPIO driver cannot find its
pin controller (pinctrl-u300), the pin controller core will
tell it to defer probing.

In Marvell PXA/MMP silicons, input schmitt disable value is 0x40, not 0.
So append new config parameter -- input schmitt disable.

Subject: [PATCH 2286/3298] pinctrl: single: support gpio request and free

Marvell's PXA/MMP silicon also match the behavior of pinctrl-single.
Each pin binds to one register. A lot of pins could be configured
as gpio.

GPIO range is defined as a child node of pinmux in .dtsi file. If those
pins are with the same gpio function configuration in the pinmux
register, they could be defined in the same GPIO range. For this new
child node, two properties are used.

reg = <the start of pinmux register in range, size of range>

pinctrl-single,gpio: <gpio base in range, the gpio function of the range
		in the pinmux register>

Subject: [PATCH 2288/3298] gpiolib: rename pin range arguments

To be crystal clear on what the arguments mean in this
funtion dealing with both GPIO and PIN ranges with confusing
naming, we now have gpio_offset and pin_offset and we are
on the clear that these are offsets into the specific GPIO
and pin controller respectively. The GPIO chip itself will
of course keep track of the base offset into the global
GPIO number space.

There are several drivers that use LEDs and depend on exactly the same

cut-and-paste into each of the binding documents. Rather than continue
to duplicate it, this patch adds a common led binding document that all

Subject: [PATCH 2297/3298] mfd: twl4030: Fix chained irq handling on resume
 from suspend

The irqs are enabled one-by-one in pm core resume_noirq phase.
This leads to situation where the twl4030 primary interrupt
handler (PIH) is enabled before the chained secondary handlers
(SIH). As the PIH cannot clear the pending interrupt, and
SIHs have not been enabled yet, a flood of interrupts hangs
the device.

Fixed the issue by setting the SIH irqs with IRQF_EARLY_RESUME
flags, so they get enabled before the PIH.

Subject: [PATCH 2298/3298] xen/netfront: handle compound page fragments on

An SKB paged fragment can consist of a compound page with order > 0.
However the netchannel protocol deals only in PAGE_SIZE frames.

Handle this in xennet_make_frags by iterating over the frames which
make up the page.

This is the netfront equivalent to 6a8ed462f16b for netback.

Subject: [PATCH 2300/3298] sign-file: fix the perl warning message when
 extracting ASN.1

There have the following warning message when running modules install
for sign ko files:

  # make modules_install
  ...
    INSTALL drivers/input/touchscreen/pcap_ts.ko
  Found = in conditional, should be == at scripts/sign-file line 164.
  Found = in conditional, should be == at scripts/sign-file line 161.
  Found = in conditional, should be == at scripts/sign-file line 159.

This patch change replace '=' by '==' in elsif conditions for avoid the
above warning messages.

Subject: [PATCH 2301/3298] team: bcast: convert return value of
 team_dev_queue_xmit() to bool correctly

The thing is that team_dev_queue_xmit() returns NET_XMIT_* or -E*.
bc_trasmit() should return true in case all went well. So use ! to get
correct retval from team_dev_queue_xmit() result.
This bug caused iface statistics to be badly computed.

This bug was introduced by:
team: add broadcast mode (5fc889911a99043a97da1daa0d010ad72cbc3042)

Subject: [PATCH 2303/3298] Dove: Attempt to fix PMU/RTC interrupts

Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner.  The PMU is one such instance.

The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)

Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed.  If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing.  So, we need to do a read-modify-write
cycle to clear the asserted bit.

However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.

The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.)  The patch below at least stops us creating
new interrupts.

Subject: [PATCH 2307/3298] clk: make ICST driver handle the VCO registers

It turns out that all platforms using the ICST VCO are really
just touching two registers, and in the same way as well: one
register with the VCO configuration as such, and one lock register
that makes it possible to write to the VCO.

Factor this register read/write into the ICST driver so we can
reuse it in the IM-PD1 driver.

Subject: [PATCH 2308/3298] clk: move IM-PD1 clocks to drivers/clk

The ARM IM-PD1 add-on module has a few clock of its own, let's
move also these down to the drivers/clk/versatile driver dir
and get rid of any remaining oldschool Integrator clocks.

Subject: [PATCH 2310/3298] [media] adv7604: Replace prim_mode by mode

Changes the way the primary mode is handled:
- Remove it from platform_data since it doesn't belong there.
- Add a new mode enum for use with s_routing.
- Collapse the two HDMI modes into one HDMI mode: when setting up the
  timings manually we do not need to select HDMI_COMP mode. That's only
  needed when selecting a preset.
This patch prepares for the next step where we switch to using the presets
where available.

Subject: [PATCH 2317/3298] CLK: SPEAr: Correct index scanning done for clock
 synths

The patch corrects the case when the rate table is being scanned for a
given frequency, and the search frequency is beyond the maximum
frequency indexed in the table.

By default, the system should be set at max frequency present in the
rate table. This patch correctly returns the corresponding index value.

Subject: [PATCH 2318/3298] CLK: SPEAr: Remove unused dummy apb_pclk

Dummy clocks were added for ARM platforms, so that clk_get() for interface clk
doesn't fail for amba devices from amba_probe(). Because there is no amba device
for SPEAr that doesn't have a valid clock with dev_id for SPEAr, we don't need
these dummy clocks. Hence, remove them.

Subject: [PATCH 2319/3298] [media] adv7604: use presets where possible

Use predefined video timings (prim_mode/vid_std) when available as recommended
by Analog Devices (http://ez.analog.com/message/48267#48267).
Also remove 720p30 support since the ADV7604 can't handle that.

Subject: [PATCH 2320/3298] [media] adv7604: restart STDI once if format is not
 found

The STDI block may measure wrong values, especially for lcvs and lcf. If the
driver can not find any valid timing, the STDI block is restarted to measure
the video timings again. The function will return an error, but the restart of
STDI will generate a new STDI interrupt and the format detection process will
restart.

Subject: [PATCH 2321/3298] w1: mxc_w1: Adapt the clock name to the new clock
 framework

With the new i.mx clock framework the mxc_w1 clock is registered as:

clk_register_clkdev(clk[owire_gate], NULL, "mxc_w1.0");

So we do not need to pass "owire" string and can use NULL instead.

While at it, also fix the clock error handling code.

Subject: [PATCH 2329/3298] mei: use structured buffer for extra write buffer

The structure of the message is static so we don't have
to use and cast the buffer. We can also drop extra_write_index
variable as this information can be extracted directly
from the message header

Subject: [PATCH 2330/3298] mei: streamline write complete flow function

Rename the function  _mei_irq_thread_cmpl to
mei_irq_thread_write_complete to make clear it deals
with writing. Remove cl from the parameter list as it
can be extracted from cb block.
Extract the common flow from if statements and document
the logic properly

Subject: [PATCH 2334/3298] mei: Simplify the ME client enumeration code

After enumerating all ME clients we call the client init functions for
all matching UUIDs from a separate context.
This remove the hackish cascading client initialisation process that was
interleaving properties and connection command replies.

This resolves the following sparse warning:

drivers/hv/hv_balloon.c:548:6: sparse: symbol 'free_balloon_pages' was not declared. Should it be static?

Date: Mon, 19 Nov 2012 13:26:26 -0500
Subject: [PATCH 2346/3298] char: remove use of __devexit

Subject: [PATCH 2348/3298] Input: ads7846 - enable pendown GPIO debounce time
 setting

Some platforms need the pendown GPIO debounce time setting programmed.
Since the pendown GPIO is handled by the driver, the debounce time
should also be handled along with the pendown GPIO request.

Subject: [PATCH 2349/3298] ARM - OMAP: ads7846: fix pendown debounce setting

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.

Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.

While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.

Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

Subject: [PATCH 2373/3298] USB: opticon: switch to generic read implementation

Switch to the more efficient generic read implementation.

Note that the generic implementation is not required to hold the tty
port mutex during resume due to the read-urb free mask and write start
flag.

Note also that the generic resume implementation will call generic
write start if there is a bulk-out end-point, but that nothing will be
submitted as the write fifo is not used and is empty.

Subject: [PATCH 2381/3298] drivers: uio_dmem_genirq: Allow partial success
 when opening device

The uio device should not fail on open just because one memory allocation
fails. The device might export several regions, the failure of some of
which may or may not be a problem for the user space driver.  Failing
regions will remain unmapped, and successful regions will be mapped and
exported to user space.  Also deals with the case where failing to map
a region after successfully allocating others would not unmap the
successfully allocated regions before dying.

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed, remove it.

This also changes the syntax for the initialization of the wl_driver
struct to match convention.

Subject: [PATCH 2401/3298] staging: et131x: Refactor et131x_isr() to remove
 indenting

By negating a 'status' variable check in et131x_isr(), we can remove
the indenting of a large block of code, increasing the readability.

This patch does exactly that.

Subject: [PATCH 2402/3298] staging: et131x: Remove alignment offset padding on
 DMA buffer allocation/free

This padding was used to align buffers to a 4k boundary when returned
from dma_alloc_coherent(). As the buffers are already 4k aligned, and
the alignment no longer performed, the padding is not needed.

 regarding alignment

A previous change removed code that aligned memory returned from
dma_alloc_coherent() to a 4k boundary, which was not necessary.

Some comments regarding this alignment still exist, so remove them
as they no longer apply.

Subject: [PATCH 2425/3298] Staging: rtl8187se: remove check for
 IW_ENCODE_DISABLED

The original code had a no-op stub where it checked if
IW_ENCODE_DISABLED and did nothing.  Then in a cleanup patch we
accidentally turned the check on.  That was: de171bd6ff "Staging:
rtl8187se: r8180_wx: fixed a lot of checkpatch.pl issues".

The check should just be removed.

Subject: [PATCH 2439/3298] staging: comedi: me_daq: remove broken workaround
 for PLX bug

The PLX PCI 9050 interface chip has a bug where its local configuration
registers accessible through PCI BAR 0 and/or PCI BAR 1 (depending on
settings loaded from a serial EEPROM or local bus processor) are
unreadable (always read 0 instead of the true register values) if the
base address starts on an odd multiple of 0x80 (i.e.  has bit 7 set to
1).

The "me_daq" driver attempts to work around this by writing to the PCI
config space to swap the addresses assigned to PCI BAR 0 and PCI BAR 5
(which has been initially configured by serial EEPROM load as a spare
region of the same length as the PCI BAR 0 region).  (If the PCI BAR 5
region is absent, it attempts to reduce the PCI BAR 0 address by 0x80,
which is likely to cause havoc for some other device, but that case
shouldn't be reachable in practice.)

The workaround in the driver is ineffective because it has already
ioremapped the memory from `pci_resource_start(pcidev, 0)` *before* it
does the workaround, so after swapping PCI BAR 0 and PCI BAR 5, this
memory will end up accessing whatever onboard registers PCI BAR 5 was
linked to instead of the local configuration registers.  It also leaves
the addresses in the physical PCI BAR registers set differently to the
resource start addresses recorded in the `struct pci_dev`.

The workaround could be fixed by ioremapping `pci_resource_start(pcidev,
5)` if the PCI BAR addresses were physically swapped (and the fallback
workaround of subtracting 0x80 from the base address should really be
removed altogether).  However, it's not really worth it.  This sort of
thing should be worked around in "drivers/pci/quirks.c" by ensuring that
PCI BAR 0 and/or PCI BAR 1 do not end up on an odd multiple of 0x80
bytes.

Subject: [PATCH 2440/3298] md/raid5: move resolving of reconstruct_state
 earlier in stripe_handle.

The chunk of code in stripe_handle which responds to a
*_result value in reconstruct_state is really the completion
of some processing that happened outside of handle_stripe
(possibly asynchronously) and so should be one of the first
things done in handle_stripe().

After the next patch it will be important that it happens before
handle_stripe_clean_event(), as that will clear some dev->flags
bit that this code tests.

Subject: [PATCH 2441/3298] md/raid5: Make sure we clear R5_Discard when
 discard is finished.

commit 9e44476851e91c86c98eb92b9bc27fb801f89072
    MD: raid5 avoid unnecessary zero page for trim

change raid5 to clear R5_Discard when the complete request is
handled rather than when submitting the per-device discard request.
However it did not clear R5_Discard for the parity device.

This means that if the stripe_head was reused before it expired from
the cache, the setting would be wrong and a hang would result.

Also if the R5_Uptodate bit happens to be set, R5_Discard again
won't be cleared.  But R5_Uptodate really should be clear at this point.

So make sure R5_Discard is cleared in all cases, and clear
R5_Uptodate when a 'discard' completes.

Date: Mon, 19 Nov 2012 13:26:36 -0500
Subject: [PATCH 2444/3298] staging: comedi: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.

Subject: [PATCH 2447/3298] ACPI: Add acpi_handle_<level>() interfaces

This patch introduces acpi_handle_<level>(), where <level> is
a kernel message level such as err/warn/info, to support improved
logging messages for ACPI, esp. hot-plug operations.
acpi_handle_<level>() appends "ACPI" prefix and ACPI object path
to the messages.  This improves diagnosis of hotplug operations
since an error message in a log file identifies an object that
caused an issue.  This interface acquires the global namespace
mutex to obtain an object path.  In interrupt context, it shows
the object path as <n/a>.

acpi_handle_<level>() takes acpi_handle as an argument, which is
passed to ACPI hotplug notify handlers from the ACPICA.  Therefore,
it is always available unlike other kernel objects, such as device.

For example:
  acpi_handle_err(handle, "Device don't exist, dropping EJECT\n");
logs an error message like this at KERN_ERR.
  ACPI: \_SB_.SCK4.CPU4: Device don't exist, dropping EJECT

ACPI hot-plug drivers can use acpi_handle_<level>() when they need
to identify a target ACPI object path in their messages, such as
error cases.  The usage model is similar to dev_<level>().
acpi_handle_<level>() can be used when a device is not created or
is invalid during hot-plug operations.  ACPI object path is also
consistent on the platform, unlike device name that gets incremented
over hotplug operations.

ACPI drivers should use dev_<level>() when a device object is valid.
Device name provides more user friendly information, and avoids
acquiring the global ACPI namespace mutex.  ACPI drivers also
continue to use pr_<level>() when they do not need to specify device
information, such as boot-up messages.

Note: ACPI_[WARNING|INFO|ERROR]() are intended for the ACPICA and
are not associated with the kernel message level.

Subject: [PATCH 2465/3298] fix incorrect NR_FREE_PAGES accounting (appears
 like memory leak)

There have been some 3.7-rc reports of vm issues, including some kswapd
bugs and, more importantly, some memory "leaks":

	http://www.spinics.net/lists/linux-mm/msg46187.html
	https://bugzilla.kernel.org/show_bug.cgi?id=50181

Commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page
immediately when it is made available") took split_free_page() and
reused it for the compaction code.  It does something curious with
capture_free_page() (previously known as split_free_page()):

  int capture_free_page(struct page *page, int alloc_order,
  ...
          __mod_zone_page_state(zone, NR_FREE_PAGES, -(1UL << order));

  -       /* Split into individual pages */
  -       set_page_refcounted(page);
  -       split_page(page, order);
  +       if (alloc_order != order)
  +               expand(zone, page, alloc_order, order,
  +                       &zone->free_area[order], migratetype);

Note that expand() puts the pages _back_ in the allocator, but it does
not bump NR_FREE_PAGES.  We "return" 'alloc_order' worth of pages, but
we accounted for removing 'order' in the __mod_zone_page_state() call.

For the old split_page()-style use (order==alloc_order) the bug will not
trigger.  But, when called from the compaction code where we
occasionally get a larger page out of the buddy allocator than we need,
we will run in to this.

This patch simply changes the NR_FREE_PAGES manipulation to the correct
'alloc_order' instead of 'order'.

I've been able to repeatedly trigger this in my testing environment.
The amount "leaked" very closely tracks the imbalance I see in buddy
pages vs.  NR_FREE_PAGES.  I have confirmed that this patch fixes the
imbalance

Subject: [PATCH 2466/3298] ACPI / PM: Introduce os_accessible flag for
 power_state

Currently we have valid flag to represent if this ACPI device power
state is valid. A device power state is valid does not necessarily
mean we, as OSPM, has a mean to put the device into that power state,
e.g. D3 cold is always a valid power state for any ACPI device, but if
there is no _PS3 or _PRx for this device, we can't really put that
device into D3 cold power state. The same is true for D0 power state.

So here comes the os_accessible flag, which is only set if the device
has provided us the required means to put it into that power state,
e.g. if we have _PS3 or _PRx, we can put the device into D3 cold state
and thus, D3 cold power state's os_accessible flag will be set in this
case.

And a new wrapper inline function is added to be used to check if
firmware has provided us a way to power off the device during runtime.

Subject: [PATCH 2467/3298] netfilter: ipset: Fix range bug in hash:ip,port,net

Due to the missing ininitalization at adding/deleting entries, when
a plain_ip,port,net element was the object, multiple elements were
added/deleted instead. The bug came from the missing dangling
default initialization.

The error-prone default initialization is corrected in all hash:* types.

Subject: [PATCH 2468/3298] netfilter: cttimeout: fix buffer overflow

Chen Gang reports:
the length of nla_data(cda[CTA_TIMEOUT_NAME]) is not limited in server side.

And indeed, its used to strcpy to a fixed-sized buffer.

Fortunately, nfnetlink users need CAP_NET_ADMIN.

From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:21:38 -0500
Subject: [PATCH 2471/3298] staging: iio: remove use of __devexit_p

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.

Subject: [PATCH 2518/3298] cpufreq: exynos: Broadcast frequency change
 notifications for all cores

On Exynos SoCs all cores share the same frequency setting, so changing
frequency of one core will affect rest of cores.

This patch modifies the exynos-cpufreq driver to inform cpufreq core
about this behavior and broadcast frequency change notifications for all
cores.

C files should include the header files that prototype their functions.
This keeps the types in sync, and eliminates warnings from GCC

From 2d47b7160243b1422006b91debf438484a4fde58 Mon Sep 17 00:00:00 2001
From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:21:34 -0500
Subject: [PATCH 2533/3298] tty: serial: remove use of __devexit_p

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The commit 81732c3b2fede049a692e58a7ceabb6d18ffb18c
("Fix line garbage in virtual console on command line edition")
made a regression with some machines: some characters were not erased
after line edition.

This patch adjusts the number of moved characters and the size of the
region to be updated.

 for nv50

Only compile time tested, noticed nv50_fence_create was never used,
so fix this. This will probably fix vblank on nv50 cards.

Hopefully this is still in time for 3.7 final release.

It doesn't make much sense to map QMgr dynamically - we almost always need it
and the static mapping will be needed for little-endian data-coherent operation
(to make QMgr region value-coherent).

Subject: [PATCH 2562/3298] IXP4xx: use __iomem for MMIO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ixp4xx queue manager uses "const struct qmgr_regs __iomem *" as the
type for a pointer that is passed to __raw_writel, which is not
allowed because of the const-ness.

Dropping the 'const' keyword fixes the problem. While we're here,
let's also drop the useless type cast.

Without this patch, building ixp4xx_defconfig results in:

Subject: [PATCH 2563/3298] md/raid10: close race that lose writes lost when
 replacement completes.

When a replacement operation completes there is a small window
when the original device is marked 'faulty' and the replacement
still looks like a replacement.  The faulty should be removed and
the replacement moved in place very quickly, bit it isn't instant.

So the code write out to the array must handle the possibility that
the only working device for some slot in the replacement - but it
doesn't.  If the primary device is faulty it just gives up.  This
can lead to corruption.

So make the code more robust: if either  the primary or the
replacement is present and working, write to them.  Only when
neither are present do we give up.

This bug has been present since replacement was introduced in

Subject: [PATCH 2564/3298] md/raid10: decrement correct pending counter when
 writing to replacement.

When a write to a replacement device completes, we carefully
and correctly found the rdev that the write actually went to
and the blithely called rdev_dec_pending on the primary rdev,
even if this write was to the replacement.

This means that any writes to an array while a replacement
was ongoing would cause the nr_pending count for the primary
device to go negative, so it could never be removed.

This bug has been present since replacement was introduced in
3.3, so it is suitable for any -stable kernel since then.

Subject: [PATCH 2567/3298] drm/exynos: fix overlay updating issue

Chagelog v2:
Move encoder's dpms updating into exynos_drm_encoder_commit
function because when crtc's dpms is updated, encoder's dpms
is updated also. This would induce the issue that encoder
isn't disabled after crtc is disabled.

Changelog v1:
This patch fixes a issue that overlay data aren't applied
to real hardware when dpms off goes to on after setcrtc
was requested like below,
    dpms off -> setcrtc -> dpms off -> dpms on

For this, it makes encoder's dpms to be updated when
setcrtc is requested.

Subject: [PATCH 2579/3298] [media] mt9v022: fix the V4L2_CID_EXPOSURE control

Since the MT9V022_TOTAL_SHUTTER_WIDTH register is controlled in manual
mode by V4L2_CID_EXPOSURE control, it shouldn't be written directly in
mt9v022_s_crop(). In manual mode this register should be set to the
V4L2_CID_EXPOSURE control value. Changing this register directly and
outside of the actual control function means that the register value
is not in sync with the corresponding control value. Thus, the following
problem is observed:
    - setting this control initially succeeds
    - VIDIOC_S_CROP ioctl() overwrites the MT9V022_TOTAL_SHUTTER_WIDTH
      register
    - setting this control to the same value again doesn't
      result in setting the register since the control value
      was previously cached and doesn't differ
Remove MT9V022_TOTAL_SHUTTER_WIDTH register setting in mt9v022_s_crop()
and add a comment explaining why it is not needed in manual mode.

Subject: [PATCH 2584/3298] drm/i915: do not default to 18 bpp for eDP if
 missing from VBT

commit 500a8cc466a24e2fbc4c86ef9c6467ae2ffdeb0c
Author: Zhenyu Wang <zhenyuw@linux.intel.com>
Date:   Wed Jan 13 11:19:52 2010 +0800

    drm/i915: parse eDP panel color depth from VBT block

originally introduced parsing bpp for eDP from VBT, with a default of 18
bpp if the eDP BIOS data block is not present. Turns out that default seems
to break the Macbook Pro with retina display, as noted in

commit 4344b813f105a19f793f1fd93ad775b784648b95
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Fri Aug 10 11:10:20 2012 +0200

    drm/i915: ignore eDP bpc settings from vbt

Since we can't ignore bpc settings from VBT completely after all, get rid
of the default. Do not clamp eDP to 18 bpp by default if the eDP BDB is
missing from VBT.

Subject: [PATCH 2585/3298] ipv4: do not cache looped multicasts

	Starting from 3.6 we cache output routes for
multicasts only when using route to 224/4. For local receivers
we can set RTCF_LOCAL flag depending on the membership but
in such case we use maddr and saddr which are not caching
keys as before. Additionally, we can not use same place to
cache routes that differ in RTCF_LOCAL flag value.

	Fix it by caching only RTCF_MULTICAST entries
without RTCF_LOCAL (send-only, no loopback). As a side effect,
we avoid unneeded lookup for fnhe when not caching because
multicasts are not redirected and they do not learn PMTU.

	Thanks to Maxime Bizon for showing the caching
problems in __mkroute_output for 3.6 kernels: different
RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or
ip_output call and the visible problem is that traffic can
not reach local receivers via loopback.

ACPI 5 introduced I2cSerialBus resource that makes it possible to enumerate
and configure the I2C slave devices behind the I2C controller. This patch
adds helper functions to support I2C slave enumeration.

An ACPI enabled I2C controller driver only needs to call acpi_i2c_register_devices()
in order to get its slave devices enumerated, created and bound to the
corresponding ACPI handle.

Subject: [PATCH 2593/3298] ARM: 7583/1: decompressor: Enable unaligned memory
 access for v6 and above

Modern GCC can generate code which makes use of the CPU's native
unaligned memory access capabilities.  This is useful for the C
decompressor implementations used for unpacking compressed kernels.

This patch disables alignment faults and enables the v6 unaligned
access model on CPUs which support these features (i.e., v6 and
later), allowing full unaligned access support for C code in the
decompressor.

The decompressor C code must not be built to assume that unaligned
access works if support for v5 or older platforms is included in
the kernel.

For correct code generation, C decompressor code must always use
the get_unaligned and put_unaligned accessors when dealing with
unaligned pointers, regardless of this patch.

Subject: [PATCH 2595/3298] dm: fix deadlock with request based dm and queue
 request_fn recursion

Request based dm attempts to re-run the request queue off the
request completion path. If used with a driver that potentially does
end_io from its request_fn, we could deadlock trying to recurse
back into request dispatch. Fix this by punting the request queue
run to kblockd.

Tested to fix a quickly reproducible deadlock in such a scenario.

Subject: [PATCH 2599/3298] mtip32xx: fix shift larger than type warning

If we're building a 32-bit kernel and CONFIG_LBADF isn't set,
sector_t is 32-bits wide. The shifts by 32 and 40 are thus
larger than we support.

Cast the sector offset to a u64 to avoid these warnings.

Calling the request handler directly on a plugged queue defeats
the performance improvements provided by the plugging mechanism.
Use the __blk_run_queue function instead of calling the request
handler directly, so that we don't interfere with the block
layer's ability to plug the queue.

Subject: [PATCH 2603/3298] block: Don't access request after it might be freed

After we've done __elv_add_request() and __blk_run_queue() in
blk_execute_rq_nowait(), the request might finish and be freed
immediately.  Therefore checking if the type is REQ_TYPE_PM_RESUME
isn't safe afterwards, because if it isn't, rq might be gone.
Instead, check beforehand and stash the result in a temporary.

This fixes crashes in blk_execute_rq_nowait() I get occasionally when
running with lots of memory debugging options enabled -- I think this
race is usually harmless because the window for rq to be reallocated
is so small.

Subject: [PATCH 2604/3298] jbd: Fix lock ordering bug in
 journal_unmap_buffer()

Commit 09e05d48 introduced a wait for transaction commit into
journal_unmap_buffer() in the case we are truncating a buffer undergoing commit
in the page stradding i_size on a filesystem with blocksize < pagesize. Sadly
we forgot to drop buffer lock before waiting for transaction commit and thus
deadlock is possible when kjournald wants to lock the buffer.

Fix the problem by dropping the buffer lock before waiting for transaction
commit. Since we are still holding page lock (and that is OK), buffer cannot
disappear under us.

Subject: [PATCH 2605/3298] MIPS: Merge overlapping bootmem ranges

Without this, we may end up with something like this in /proc/iomem:

  01100000-013bf48f : Kernel code
  013bf490-0149e01f : Kernel data
01500000-0c0fffff : System RAM

but the two System RAM ranges should be one single range.  This particular
case will result in kexec failure on Octeon systems if the kernel being
loaded by kexec is bigger than the already running kernel.

Subject: [PATCH 2606/3298] MIPS: Fix crash that occurs when function tracing
 is enabled

A recent patch changed some irq routines from inlines to functions.
These routines are called by the tracer code. Now that they're functions,
if they are compiled for function tracing they will call the tracer
and crash the system due to infinite recursion. The fix disables
tracing in these functions by using "notrace" in the function
definition.

Subject: [PATCH 2612/3298] PM / QoS: fix wrong error-checking condition

dev_pm_qos_add_request() can return 0, 1, or a negative error code,
therefore the correct error test is "if (error < 0)." Checking just for
non-zero return code leads to erroneous setting of the req->dev pointer
to NULL, which then leads to a repeated call to
dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
leads to an Oops, when the I2C host adapter is unloaded and reloaded again
because of the inconsistent state of its QoS request list.

Subject: [PATCH 2613/3298] ACPI / PNP: skip ACPI device nodes associated with
 physical nodes already

Make pnpacpi_add_device() ignore ACPI device nodes already associated
with struct device objects representing physical devices.

In particular, this will prevent PNP device objects from being
created for ACPI device nodes already associated with platform
devices.

This change was originally proposed by Mika Westerberg.

Subject: [PATCH 2617/3298] of/address: sparc: Declare of_iomap as an extern
 function for sparc again

This bug-fix makes sure that of_iomap is defined extern for sparc so that the
sparc-specific implementation of_iomap is once again used when including
include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
sparc relies on this.

The bug was inadvertently introduced in a850a75, "of/address: add empty static
inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
!CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.

This fix takes the same approach as 0bce04b that solved the equivalent problem
for of_address_to_resource.

Subject: [PATCH 2618/3298] perf kvm: Rename perf_kvm to perf_kvm_stat

Then let it only be used in 'perf kvm stat'.

Preparatory patch to stop trying to build parts of this tool that for
now are only supported on x86.

Now, 'perf kvm stat' is only supported on x86, let its code depend on
(__x86_64__ || __i386__) to fix building it on other architectures.

Subject: [PATCH 2620/3298] cpufreq: governors: Fix jiffies/cputime mixup
 (revisited)

This change was made by commit 8636fd2 (cpufreq: fix jiffies/cputime
mixup in conservative/ondemand governors) before, but then it has
been reverted inadvertently by commit 4471a34 (cpufreq: governors:
remove redundant code).

The changelog of commit 8636fd2's says:

  The function get_cpu_idle_time_jiffy in both the conservative and
  ondemand governors use jiffies_to_usecs to convert a cputime value
  to usecs which gives the wrong value on architectures where cputime
  and jiffies use different units.  Only matters if NO_HZ is
  disabled, since otherwise get_cpu_idle_time_us should already
  return a valid value, and get_cpu_idle_time_jiffy isn't actually
  called.

Since now we have only one common get_cpu_idle_time_jiffy() used by

Subject: [PATCH 2621/3298] PM / QoS: Handle device PM QoS flags while removing
 constraints

PM QoS flags have to be handled by dev_pm_qos_constraints_destroy()
in the same way as PM QoS resume latency constraints.  That is, if
they have been exposed to user space, they have to be hidden from it
and the list of flags requests has to be flushed before destroying
the device's PM QoS object.  Make that happen.

    drm/i915: disable rc6 on ilk when vt-d is enabled

Note: The situation around the gen4/5 gpu hangs that cropped up in 3.7
is rather strange. Most useful bisects have lead to

commit 6c085a728cf000ac1865d66f8c9b52935558b328

    drm/i915: Track unbound pages

or even later commits that affect the gem bo recycling, which all is
way past the point where we re-enabled rc6. But somehow
reverting/disabling those commits doesn't help, but disabling rc6 at
least helps for many hangs on ilk. Obviously it doesn't change
anything at all on gen4, and there are still strange issues left on
gen5 (which we unfortunately can't readily reproduce).

Also, the error_state signature of the hangs which can be fixed with
this patch look remarkably different to those which seem to be
unaffected by the rc6 settings: The rc6 hangs are in the ring,
somewhere in the MI_FLUSH/PIPE_CONTROL sequence to make ilk coherent,
wheras all the other hangs tend to be at a random point in the middle
of the user batch. So it could also be that we have different issues.

Until we grow more clue, this at least helps some users.

While the EEH does recovery on the specific PE that has PCI errors,
the PCI devices belonging to the PE will be removed and the PE will
be marked as invalid since we still need the information stored in
the PE. We only invalidate the PE when it doesn't have associated
EEH devices and valid child PEs. However, the code used to check
that is wrong. The patch fixes that.

Subject: [PATCH 2632/3298] clk: ux500: Initial support for abx500 clock driver

The abx500 clock driver is a platform driver which will be initialized
during arch init. The platform device shall be added from the ab-core
driver as a mfd child device to maintain correct boot sequence.

Depending on what ab version we use, different clock definitions will
be added.

Subject: [PATCH 2633/3298] clk: clock multiplexers may register out of order

When a clock, C is initialised any orphan clocks listing C as
a possible parent are reparented to it regardless of the
parent requested by the orphan's get_parent() operation.

This means that multiplexers registered before their parents
are reparented to the first parent subsequently declared,
regardless of the selection made by the hardware registers.

For example:
	static const char *sel[] = { "srcA", "srcB", "dummy", "srcC" };

	child = clk_register_mux(NULL, "child",  sel, ARRAY_SIZE(sel), ...);
	clk_register_fixed(NULL, "dummy", ...);
	clk_register_fixed(NULL, "srcA", ...);
	clk_register_fixed(NULL, "srcB", ...);
	clk_register_fixed(NULL, "srcC", ...);

Causes child's parent to always be "dummy".

To fix this, when an orphanned clock has a get_parent() operation,
only reparent to the clock indicated by get_parent().

Subject: [PATCH 2634/3298] mac80211: fix remain-on-channel (non-)cancelling

Felix Liao reported that when an interface is set DOWN
while another interface is executing a ROC, the warning
in ieee80211_start_next_roc() (about the first item on
the list having started already) triggers.

This is because ieee80211_roc_purge() calls it even if
it never actually changed the list of ROC items. To fix
this, simply remove the function call. If it is needed
then it will be done by the ieee80211_sw_roc_work()
function when the ROC item that is being removed while
active is cleaned up.

Make sure when fimc and fimc-lite capture video node is registered
it has valid pipeline_ops assigned to it. Otherwise when a video
node is opened right after is was registered there, might be an
attempt to use ops that are just being assigned, after function
v4l2_device_register_subdev() returns.

Use uninterruptible mutex_lock in the release() file op to make
sure all resources are properly freed when a process is being
terminated. Returning -ERESTARTSYS has no effect for a terminating
process and this caused driver resources not to be released. Not
releasing the buffer queue also prevented other drivers to free
memory, e.g. in MMAP -> USERPTR scenario.
This patch is required for stable kernels v3.6+.

Subject: [PATCH 2643/3298] can: peak_usb: fix hwtstamp assignment

The skb->tstamp is set to the hardware timestamp when available in the USB
urb message. This leads to user visible timestamps which contain the 'uptime'
of the USB adapter - and not the usual system generated timestamp.

Fix this wrong assignment by applying the available hardware timestamp to the
skb_shared_hwtstamps data structure - which is intended for this purpose.

Subject: [PATCH 2647/3298] USB: OHCI: workaround for hardware bug: retired TDs
 not added to the Done Queue

This patch (as1636) is a partial workaround for a hardware bug
affecting OHCI controllers by NVIDIA at least, maybe others too.  When
the controller retires a Transfer Descriptor, it is supposed to add
the TD onto the Done Queue.  But sometimes this doesn't happen, with
the result that ohci-hcd never realizes the corresponding transfer has
finished.  Symptoms can vary; a typical result is that USB audio stops
working after a while.

The patch works around the problem by recognizing that TDs are always
processed in order.  Therefore, if a later TD is found on the Done
Queue than all the earlier TDs for the same endpoint must be finished
as well.

Unfortunately this won't solve the problem in cases where the missing
TD is the last one in the endpoint's queue.  A complete fix would
require a signficant amount of change to the driver.

this:

All interfaces have the same ff/ff/ff class codes in this mode.

Subject: [PATCH 2657/3298] serial: samsung: fix potential soft lockup during
 uart write

Certain tty line discipline implementations such slip and bluetooth hci invoke
the serial core uart_write() api in their write_wakeup callback. This leads to
a soft lockup with samsung serial driver since the uart port lock is taken in
the driver's interrupt handler and uart_write() attempts to take the same lock
again.

Fix this issue by releasing the uart port lock before the call to
uart_write_wakeup() in the tx handler. Also move the spin-lock/unlock sequence
from s3c64xx_serial_handle_irq() function into the tx and rx irq handlers so
that this change is applicable to s3c24xx platforms as well.

Subject: [PATCH 2661/3298] serial: mxs-auart: disable the Receive Timeout
 Interrupt when DMA is enabled

When the DMA is enabled, the Receive Timeout interrupt is very easy to be arised
in the 3M baud rate.  The interrupt handler (aka mxs_auart_irq_handle) will call
mxs_auart_rx_chars() to handle the received data. This is not right, we can not
get the correct data from the RXFIFO now, the data have been moved to the
DMA buffer by the DMA engine.

This patch
  (1) disables the Receive Timeout Interrupt when the DMA is enabled,
  (2) and invoke the mxs_auart_rx_chars() only when the DMA is not enabled.

Subject: [PATCH 2663/3298] x86, apic: Cleanup cfg->domain setup for legacy
 interrupts

Issues that need to be handled:
* Handle PIC interrupts on any CPU irrespective of the apic mode
* In the apic lowest priority logical flat delivery mode, be prepared to
  handle the interrupt on any CPU irrespective of what the IO-APIC RTE says.
* Because of above, when the IO-APIC starts handling the legacy PIC interrupt,
  use the same vector that is being used by the PIC while programming the
  corresponding IO-APIC RTE.

Start with all the cpu's in the legacy PIC interrupts cfg->domain.

By the time IO-APIC starts taking over the PIC interrupts, apic driver
model is finalized. So depend on the assign_irq_vector() to update the
cfg->domain and retain the same vector that was used by PIC before.

For the logical apic flat mode, cfg->domain is updated (during the first
call to assign_irq_vector()) to contain all the possible online cpu's (0xff).
Vector used for the legacy PIC interrupt doesn't change when the IO-APIC
starts handling the interrupt. Any interrupt migration after that
doesn't change the cfg->domain or the vector used.

For other apic modes like physical mode, cfg->domain is updated
(during the first call to assign_irq_vector()) to the boot cpu (cpu-0),
with the same vector that is being used by the PIC. When that interrupt is
migrated to a different cpu, cfg->domin and the vector assigned will change
accordingly.

In __emulate_1op_rax_rdx, we use "+a" and "+d" which are input/output
constraints, and *then* use "a" and "d" as input constraints.  This is
incorrect, but happens to work on some versions of gcc.

However, it breaks gcc with -O0 and icc, and may break on future
versions of gcc.

Subject: [PATCH 2677/3298] Staging: Android: logger: module_exit
 implementation

This patch creates the module_exit for the android logger
so that it can be loaded and unloaded as a module.

The android logger is already declared as a tristate in the
Kconfig but the module_exit function was missing.

device_initcall works also with modprobe since include/linux/init.h:

 #define module_init(x)  __initcall(x);
 ...
 #define __initcall(fn) device_initcall(fn)

Tested against f4a75d2eb7b1e2206094b901be09adb31ba63681 Linux 3.7-rc6

Subject: [PATCH 2700/3298] Staging: bcm: Remove typedef for stUserThreadReq
 and call directly.

This patch removes typedef for stUserThreadReq,
and changes the name of the struct to bcm_user_thread_req.
In addition, any calls to typedefs USER_THREAD_REQ, or
*PUSER_THREAD_REQ are changed to call the struct directly.

Subject: [PATCH 2703/3298] Staging: bcm: Remove typedef for wrmbuffer and call
 directly.

This patch removes typedef for wrmbuffer, and
changes the name of the struct to bcm_wrm_buffer.
In addition, any calls to typedefs WRM_BUFFER, or
*PWRM_BUFFER are changed to call the struct
directly.

Subject: [PATCH 2706/3298] staging: dgrp: dgrp_tty.c: Audit the return values
 of get/put_user()

fix for missing audits for return values of get_user() and put_user().
Inspecting the return values of get/put_user() would make the access_ok()
redundant, hence removing calls to access_ok() in such scenarios.

Subject: [PATCH 2721/3298] Staging: bcm: Remove typedef for
 _S_MIBS_HOST_STATS_MIBS and call directly.

This patch removes typedef for _S_MIBS_HOST_STATS_MIBS,
and changes the name of the struct to bcm_host_stats_mibs.
In addition, any calls to typedefs S_MIBS_HOST_STATS_MIBS
are changed to call the struct directly.

Subject: [PATCH 2727/3298] Staging: bcm: Remove typedef for _S_MIBS_HOST_INFO
 and call directly.

This patch removes typedef for _S_MIBS_HOST_INFO, and
changes the name of the struct to bcm_mibs_host_info.
In addition, any calls to typedef S_MIBS_HOST_INFO are
changed to call the struct directly.

The param_dirty bitmap tracks which parameters have been modified since
saving a preset.  The bitmap is never used though so we can drop this
deadcode.

Subject: [PATCH 2733/3298] staging: line6: drop dump sysfs attr

Once further sysfs attrs have been removed it will also be possible to
drop prog_data and other pieces which we keep for now.

Subject: [PATCH 2735/3298] staging: line6: drop monitor_level sysfs attr

The monitor level can be adjusted using an ALSA volume control.
Therefore the sysfs attribute is unnecessary.  Note that we leave the
monitor_level driver variable so that the ALSA volume control still
works.

 -> int

The monitor_level sysfs attr has been dropped and we never need to wait
on the monitor_level value to change.  Switch to a plain int and drop
the wait queue.

Subject: [PATCH 2749/3298] staging: line6: drop tuner_pitch sysfs attr

Dropping this final tuner sysfs attr also leaves the
POD_GET_SYSTEM_PARAM() macro, pod_get_system_param_string(), and
pod_get_system_param_int() unused.  Remove them immediately to avoid
compiler warnings.

POD_monitor_level is now the only SYSEX value that needs to be watched
by the driver since the ALSA volume control should reflect the current
monitor volume level used by the device.  Therefore, drop the switch
statement entirely and just check for POD_monitor_level, ignoring
unknown system parameter changes.

Subject: [PATCH 2752/3298] staging: line6: drop midi_mask_receive

The midi_mask_receive sysfs attribute selects the MIDI channels on which
to receive messages.  There is no need to do this at the driver level,
instead the MIDI application endpoints decide which channels to use.
Other drivers don't implement midi_mask_receive so applications cannot
make use of this feature.  Therefore we drop it as part of the effort to
clean up the staging driver.

Subject: [PATCH 2753/3298] staging: line6: drop midi_mask_transmit

The midi_mask_transmit sysfs attribute selects the MIDI channels on
which to transmit messages.  If ALSA wants to transmit a message that
does not match an allowed channel, the message will be dropped.  This
driver feature is not really used and applications don't know how to
take advantage of it.  Therefore we drop it and rely on applications or
MIDI sequencers to select the channels used for communication.

Subject: [PATCH 2754/3298] staging: line6: drop midi_postprocess flag

It is no longer necessary to trigger on MIDI transmit messages that will
change the state of the device since:

1. We've dropped the midi_postprocess sysfs attr in a previous commit so
   it is not possible to activate this feature anymore.

2. The other sysfs attrs that could inspect the state after a dump
   request have been dropped.

Therefore we can safely remove this dead code.

Subject: [PATCH 2755/3298] staging: line6: drop pod.c raw sysfs attr

The raw sysfs attr transmits MIDI messages with less filtering.  This
was a useful debugging tool while the staging driver still had a lot of
state and filtering.  It is not useful anymore since the filtering is
being dropped.

Subject: [PATCH 2756/3298] staging: line6: drop tuner param filtering

The pod_set_system_param_int() helper function is only used to set the
monitor level.  Previously it was also used to control the tuner and has
special checks.  These checks can now be dropped, along with the tuner
constants.

Subject: [PATCH 2766/3298] staging: line6: drop CONFIG_LINE6_USB_RAW

Now that both pod.c and variax.c have removed their raw sysfs attrs, the
CONFIG_LINE6_USB_RAW config option can be dropped.  The drivers are
being stripped down to just PCM and MIDI I/O so there is less state and
filtering.  Therefore it's no longer necessary to have a special sysfs
attr to bypass the filtering ("raw").

Since the driver no longer needs to keep state of device parameters it
is no longer necessary to refresh state when messages that affect other
parameters are sent.  Drop the code to trigger a dump when amp/effects
are changed.

Subject: [PATCH 2768/3298] staging: line6: drop MIDI parameter sysfs attrs

Both pod.c and variax.c expose the device's MIDI parameters as sysfs
attrs.  Knowledge of MIDI constants should be in userspace, not in the
driver.  Drop the sysfs attrs and let userspace interpret parameters it
cares about instead.

Subject: [PATCH 2769/3298] staging: line6: drop pod prog_data buffers

The driver no longer keeps state of MIDI-accessible device parameters.
Drop the buffers but be careful to keep the device startup procedure
working even though we no longer store the contents of the dump request.
The startup procedure will be simplified in a later patch.

The sysfs attrs to access the model dump have been removed so it's safe
to drop the model_data field.  The next step will be to simplify the
startup process since we no longer need to fetch this data via dump
requests, but that will be done in a later patch.

Subject: [PATCH 2772/3298] staging: line6: drop dump requests from variax
 startup

The variax startup procedure dumps model data.  This is no longer useful
since the sysfs attrs which expose this information to userspace have
been removed.  The dump request wasn't been processed anymore.

Subject: [PATCH 2776/3298] w1-gpio: Simplify & get rid of defines

There's no reason to have the OF defines; it complicates the driver.
There's also no need for the funky platform_driver_probe.

Add a few warnings in case there's a failure; helps us find out
what went wrong.

It also fixes usb_set_intfdata() in gdm_usb_probe to avoid setting an
already freed phy_dev.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

syscore_shutdown uses initcall_debug to control the debug info output.
It’s a good programming. But device_shutdown doesn’t. The patch changes
device_shutdown to follow the style.

Subject: [PATCH 2799/3298] md/raid1{,0}: fix deadlock in bitmap_unplug.

If the raid1 or raid10 unplug function gets called
from a make_request function (which is very possible) when
there are bios on the current->bio_list list, then it will not
be able to successfully call bitmap_unplug() and it could
need to submit more bios and wait for them to complete.
But they won't complete while current->bio_list is non-empty.

So detect that case and handle the unplugging off to another thread
just like we already do when called from within the scheduler.

RAID1 version of bug was introduced in 3.6, so that part of fix is
suitable for 3.6.y.  RAID10 part won't apply.

Subject: [PATCH 2801/3298] UAPI: strip the _UAPI prefix from header guards

Strip the _UAPI prefix from header guards during header installation so
that any userspace dependencies aren't affected.  glibc, for example,
checks for linux/types.h, linux/kernel.h, linux/compiler.h and
linux/list.h by their guards - though the last two aren't actually
exported.

Subject: [PATCH 2802/3298] proc: check vma->vm_file before dereferencing

Commit 7b540d0646ce ("proc_map_files_readdir(): don't bother with
grabbing files") switched proc_map_files_readdir() to use @f_mode
directly instead of grabbing @file reference, but same time the test for
@vm_file presence was lost leading to nil dereference.  The patch brings
the test back.

The all proc_map_files feature is CONFIG_CHECKPOINT_RESTORE wrapped
(which is set to 'n' by default) so the bug doesn't affect regular
kernels.

The regression is 3.7-rc1 only as far as I can tell.

Subject: [PATCH 2803/3298] Revert "mm: remove __GFP_NO_KSWAPD"

With "mm: vmscan: scale number of pages reclaimed by reclaim/compaction
based on failures" reverted, Zdenek Kabelac reported the following

  Hmm,  so it's just took longer to hit the problem and observe
  kswapd0 spinning on my CPU again - it's not as endless like before -
  but still it easily eats minutes - it helps to	turn off  Firefox
  or TB  (memory hungry apps) so kswapd0 stops soon - and restart
  those apps again.  (And I still have like >1GB of cached memory)

  kswapd0         R  running task        0    30      2 0x00000000
  Call Trace:
    preempt_schedule+0x42/0x60
    _raw_spin_unlock+0x55/0x60
    put_super+0x31/0x40
    drop_super+0x22/0x30
    prune_super+0x149/0x1b0
    shrink_slab+0xba/0x510

The sysrq+m indicates the system has no swap so it'll never reclaim
anonymous pages as part of reclaim/compaction.  That is one part of the
problem but not the root cause as file-backed pages could also be
reclaimed.

The likely underlying problem is that kswapd is woken up or kept awake
for each THP allocation request in the page allocator slow path.

If compaction fails for the requesting process then compaction will be
deferred for a time and direct reclaim is avoided.  However, if there
are a storm of THP requests that are simply rejected, it will still be
the the case that kswapd is awake for a prolonged period of time as
pgdat->kswapd_max_order is updated each time.  This is noticed by the
main kswapd() loop and it will not call kswapd_try_to_sleep().  Instead
it will loopp, shrinking a small number of pages and calling
shrink_slab() on each iteration.

The temptation is to supply a patch that checks if kswapd was woken for
THP and if so ignore pgdat->kswapd_max_order but it'll be a hack and not
backed up by proper testing.  As 3.7 is very close to release and this
is not a bug we should release with, a safer path is to revert "mm:
remove __GFP_NO_KSWAPD" for now and revisit it with the view to ironing
out the balance_pgdat() logic in general.

Subject: [PATCH 2804/3298] mm: vmscan: check for fatal signals iff the process
 was throttled

Commit 5515061d22f0 ("mm: throttle direct reclaimers if PF_MEMALLOC
reserves are low and swap is backed by network storage") introduced a
check for fatal signals after a process gets throttled for network
storage.  The intention was that if a process was throttled and got
killed that it should not trigger the OOM killer.  As pointed out by
Minchan Kim and David Rientjes, this check is in the wrong place and too
broad.  If a system is in am OOM situation and a process is exiting, it
can loop in __alloc_pages_slowpath() and calling direct reclaim in a
loop.  As the fatal signal is pending it returns 1 as if it is making
forward progress and can effectively deadlock.

This patch moves the fatal_signal_pending() check after throttling to
throttle_direct_reclaim() where it belongs.  If the process is killed
while throttled, it will return immediately without direct reclaim
except now it will have TIF_MEMDIE set and will use the PFMEMALLOC
reserves.

Minchan pointed out that it may be better to direct reclaim before
returning to avoid using the reserves because there may be pages that
can easily reclaim that would avoid using the reserves.  However, we do
no such targetted reclaim and there is no guarantee that suitable pages
are available.  As it is expected that this throttling happens when
swap-over-NFS is used there is a possibility that the process will
instead swap which may allocate network buffers from the PFMEMALLOC
reserves.  Hence, in the swap-over-nfs case where a process can be
throtted and be killed it can use the reserves to exit or it can
potentially use reserves to swap a few pages and then exit.  This patch
takes the option of using the reserves if necessary to allow the process
exit quickly.

If this patch passes review it should be considered a -stable candidate
for 3.6.

Subject: [PATCH 2805/3298] writeback: put unused inodes to LRU after writeback
 completion

Commit 169ebd90131b ("writeback: Avoid iput() from flusher thread")
removed iget-iput pair from inode writeback.  As a side effect, inodes
that are dirty during iput_final() call won't be ever added to inode LRU
(iput_final() doesn't add dirty inodes to LRU and later when the inode
is cleaned there's noone to add the inode there).  Thus inodes are
effectively unreclaimable until someone looks them up again.

The practical effect of this bug is limited by the fact that inodes are
pinned by a dentry for long enough that the inode gets cleaned.  But
still the bug can have nasty consequences leading up to OOM conditions
under certain circumstances.  Following can easily reproduce the
problem:

  for (( i = 0; i < 1000; i++ )); do
    mkdir $i
    for (( j = 0; j < 1000; j++ )); do
      touch $i/$j
      echo 2 > /proc/sys/vm/drop_caches
    done
  done

then one needs to run 'sync; ls -lR' to make inodes reclaimable again.

We fix the issue by inserting unused clean inodes into the LRU after
writeback finishes in inode_sync_complete().

Subject: [PATCH 2806/3298] watchdog: using u64 in get_sample_period()

In get_sample_period(), unsigned long is not enough:

  watchdog_thresh * 2 * (NSEC_PER_SEC / 5)

case1:
  watchdog_thresh is 10 by default, the sample value will be: 0xEE6B2800

case2:
 set watchdog_thresh is 20, the sample value will be: 0x1 DCD6 5000

In case2, we need use u64 to express the sample period.  Otherwise,
changing the threshold thru proc often can not be successful.

Subject: [PATCH 2807/3298] futex: avoid wake_futex() for a PI futex_q

Dave Jones reported a bug with futex_lock_pi() that his trinity test
exposed.  Sometime between queue_me() and taking the q.lock_ptr, the
lock_ptr became NULL, resulting in a crash.

While futex_wake() is careful to not call wake_futex() on futex_q's with
a pi_state or an rt_waiter (which are either waiting for a
futex_unlock_pi() or a PI futex_requeue()), futex_wake_op() and
futex_requeue() do not perform the same test.

Update futex_wake_op() and futex_requeue() to test for q.pi_state and
q.rt_waiter and abort with -EINVAL if detected.  To ensure any future
breakage is caught, add a WARN() to wake_futex() if the same condition
is true.

This fix has seen 3 hours of testing with "trinity -c futex" on an
x86_64 VM with 4 CPUS.

Subject: [PATCH 2808/3298] platform / ACPI: Attach/detach ACPI PM during
 probe/remove/shutdown

Drivers usually expect that the devices they are supposed to handle
will be operational when their .probe() routines are called, but that
need not be the case on some ACPI-based systems with ACPI-based
device enumeration where the BIOSes don't put devices into D0 by
default.  To work around this problem it is sufficient to change
bus type .probe() routines to ensure that devices will be powered
on before the drivers' .probe() routines run (and their .remove()
and .shutdown() routines accordingly).

Modify platform_drv_probe() to run acpi_dev_pm_attach() for devices
whose ACPI handles are present, so that ACPI power management is used
to change their power states.  Analogously, modify
platform_drv_remove() and platform_drv_shutdown() to call
acpi_dev_pm_detach() for those devices, so that they are not subject
to ACPI PM any more.

+SPEAr cpufreq driver
+-------------------
+
+SPEAr SoC cpufreq driver for CPU frequency scaling.
+It supports both uniprocessor (UP) and symmetric multiprocessor (SMP) systems
+which share clock across all CPUs.
+
+Required properties:
+- cpufreq_tbl: Table of frequencies CPU could be transitioned into, in the
+  increasing order.
+
+Optional properties:
+- clock-latency: Specify the possible maximum transition latency for clock, in
+  unit of nanoseconds.
+
+Both required and optional properties listed above must be defined under node
+/cpus/cpu@0.
+
+Examples:
+--------
+cpus {
+
+	<...>
+
+	cpu@0 {
+		compatible = "arm,cortex-a9";
+		reg = <0>;
+
+		<...>
+
+		cpufreq_tbl = < 166000

Subject: [PATCH 2812/3298] cpufreq: ondemand: update sampling rate only on
 right CPUs

Fix cpufreq_gov_ondemand to skip CPU where another governor is used.

The bug present itself as NULL pointer access on the mutex_lock() call,
an can be reproduced on an SMP machine by setting the default governor
to anything other than ondemand, setting a single CPU's governor to
ondemand, then changing the sample rate by writing on:

> /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate

Subject: [PATCH 2813/3298] cpuidle: Measure idle state durations with
 monotonic clock

Many cpuidle drivers measure their time spent in an idle state by
reading the wallclock time before and after idling and calculating the
difference. This leads to erroneous results when the wallclock time gets
updated by another processor in the meantime, adding that clock
adjustment to the idle state's time counter.

If the clock adjustment was negative, the result is even worse due to an
erroneous cast from int to unsigned long long of the last_residency
variable. The negative 32 bit integer will zero-extend and result in a
forward time jump of roughly four billion milliseconds or 1.3 hours on
the idle state residency counter.

This patch changes all affected cpuidle drivers to either use the
monotonic clock for their measurements or make use of the generic time
measurement wrapper in cpuidle.c, which was already working correctly.
Some superfluous CLIs/STIs in the ACPI code are removed (interrupts
should always already be disabled before entering the idle function, and
not get reenabled until the generic wrapper has performed its second
measurement). It also removes the erroneous cast, making sure that
negative residency values are applied correctly even though they should
not appear anymore.

There appear to have been some 486 clones, including the "enhanced"
version of Am486, which have CPUID but not CR4.  These 486 clones had
only the FPU flag, if any, unlike the Intel 486s with CPUID, which
also had VME and therefore needed CR4.

Therefore, look at the basic CPUID flags and require at least one bit
other than bit 0 before we modify CR4.

Thanks to Christian Ludloff of sandpile.org for confirming this as a
problem.

Subject: [PATCH 2827/3298] ACPI / thermal: _TMP and _CRT/_HOT/_PSV/_ACx
 dependency fix

On some platforms, _TMP and _CRT/_HOT/_PSV/_ACx have dependency.
And there is no way for OS to detect this dependency.

commit 9bcb8118965ab4631a65ee0726e6518f75cda6c5 shows us a problem
that _TMP must be evaluate after _CRT/_HOT/_PSV/_ACx, or else
firmware will shutdown the system.

But the machine in https://bugzilla.kernel.org/show_bug.cgi?id=43284
shows us that _PSV would return valid value only if _TMP has been
evaluated once.

With this patch, all of the control methods will be evaluated once,
in the _CRT/_HOT/_PSV/_CRT/_TMP order, before they are actually used.

[rjw: Added a local variable for the handle and modified the loop
 slightly.]

Subject: [PATCH 2828/3298] cifs: fix writeback race with file that is growing

Commit eddb079deb4 created a regression in the writepages codepath.
Previously, whenever it needed to check the size of the file, it did so
by consulting the inode->i_size field directly. With that patch, the
i_size was fetched once on entry into the writepages code and that value
was used henceforth.

If the file is changing size though (for instance, if someone is writing
to it or has truncated it), then that value is likely to be wrong. This
can lead to data corruption. Pages past the EOF at the time that the
writepages call was issued may be silently dropped and ignored because
cifs_writepages wrongly assumes that the file must have been truncated
in the interim.

Fix cifs_writepages to properly fetch the size from the inode->i_size
field instead to properly account for this possibility.

Original bug report is here:

    https://bugzilla.kernel.org/show_bug.cgi?id=50991

Subject: [PATCH 2830/3298] cpupower tools: Remove brace expansion from clean
 target

The clean targets from the cpupower tools' Makefiles use brace expansion to
remove some generated files. However, the default shells on many systems do
not support this feature resulting in some generated files not being removed
by clean.

Subject: [PATCH 2833/3298] cpupower tools: Fix issues with
 sysfs_topology_read_file

Fix a variety of issues with sysfs_topology_read_file:
* The return value of sysfs_topology_read_file function was not properly
  being checked for failure.
* The function was reading int valued sysfs variables and then returning
  their value. So, even if a function was trying to check the return value
  of this function, a caller would not be able to tell an failure code apart
  from reading a negative value. This also conflicted with the comment on the
  function which said that a return value of 0 indicated success.
* The function was parsing int valued sysfs values with strtoul instead of
  strtol.
* The function was non-static even though it was only used in the
  file it was declared in.

Subject: [PATCH 2834/3298] cpupower tools: Fix malloc of cpu_info structure

The cpu_info member of cpupower_topology was being declared as an unnamed
structure. This member was then being malloced using the size of the
parent cpupower_topology * the number of cpus. This works
because cpu_info is smaller than cpupower_topology. However, there is
no guarantee that will always be the case. Making cpu_info its own
top level structure (named cpuid_core_info) allows for mallocing the actual
size of this structure. This also lets us get rid of a redefinition of
the structure in topology.c with slightly different field names.

Subject: [PATCH 2835/3298] cpupower tools: Fix warning and a bug with the cpu
 package count

The pkgs member of cpupower_topology is being used as the number of
cpu packages. As the comment in get_cpu_topology notes, the package ids
are not guaranteed to be contiguous. So, simply setting pkgs to the value
of the highest physical_package_id doesn't actually provide a count of
the number of cpu packages. Instead, calculate pkgs by setting it to
the number of distinct physical_packge_id values which is pretty easy
to do after the core_info structs are sorted. Calculating pkgs this
way also has the nice benefit of getting rid of a sign comparison warning
that GCC 4.6 was reporting.

Subject: [PATCH 2836/3298] cpupower: Provide -c param for cpupower monitor to
 schedule process on all cores

If an MSR based monitor is run in parallel this is not needed. This is the
default case on all/most Intel machines.

But when only sysfs info is read via cpupower monitor -m Idle_Stats (typically
the case for non root users) or when other monitors are PCI based (AMD),
Idle_Stats, read from sysfs can be totally bogus:

cpupower monitor -m Idle_Stats
PKG |CORE|CPU | POLL | C1-N | C3-N | C6-N
   0|   0|   0|  0.00|  0.00|  0.24| 99.81
   0|   0|  32|  0.00|  0.00|  0.00| 100.7
...
   0|  17|  20|  0.00|  0.00|  0.00| 173.1
   0|  17|  52|  0.00|  0.00|  0.07| 173.0
   0|  18|  68|  0.00|  0.00|  0.00|  0.00
   0|  18|  76|  0.00|  0.00|  0.00|  0.00
...

With the -c option all cores are woken up and the kernel
did update cpuidle statistics before reading out sysfs.
This causes some overhead. Therefore avoid if possible, use
if needed:

cpupower monitor -c -m Idle_Stats
PKG |CORE|CPU | POLL | C1-N | C3-N | C6-N
   0|   0|   0|  0.00|  0.00|  0.00| 100.2
   0|   0|  32|  0.00|  0.00|  0.00| 100.2
...
   0|   8|   8|  0.00|  0.00|  0.00| 99.82
   0|   8|  40|  0.00|  0.00|  0.00| 99.81

Subject: [PATCH 2838/3298] i7core_edac: fix panic when accessing sysfs files

The i7core_edac addrmatch_dev and chancounts_dev have sysfs files
associated with them.  The sysfs files, however, are coded so that the
parent device is is the mci device.  This is incorrect and the mci struct
should be obtained through the addrmatch_dev and chancounts_dev device's
private data field which is populated in i7core_create_sysfs_devices().

Subject: [PATCH 2839/3298] ARM: 7586/1: sp804: set cpumask to
 cpu_possible_mask for clock event device

The SP804 driver statically initialises the cpumask of the clock event
device to be cpu_all_mask, which is derived from the compile-time
constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
controller handling the sp804 doesn't have the irq_set_affinity callback
on the irq_chip, because the common timer code fails to identify the
device as cpu-local and ends up treating it as a broadcast device
instead.

This patch fixes the problem by using cpu_possible_mask at runtime,
which will correctly represent the possible CPUs when SMP_ON_UP is being
used.

Subject: [PATCH 2846/3298] amd64_edac: Improve error injection

When injecting DRAM ECC errors over the F3xB[8,C] interface, the machine
does this by injecting the error in the next non-cached access. This
takes relatively long time on a normal system so that in order for us to
expedite it, we disable the caches around the injection.

Subject: [PATCH 2848/3298] amd64_edac: Reorganize error reporting path

Rewrite CE/UE paths so that they use the same code and drop additional
code duplication in handle_ue. Add a struct err_info which collects
required info for the error reporting. This, in turn, helps slimming all
edac_mc_handle_error() calls down to one.

Subject: [PATCH 2849/3298] amd64_edac: Fix K8 chip select reporting

This basically reverts 603adaf6b3e3 ("amd64_edac: fix K8 chip select
reporting") because it was a clumsy workaround for DIMM sizes reporting
on K8 which got superceded by a much more correct one with 41d8bfaba70
("amd64_edac: Improve DRAM address mapping") without removing the prior
one. Remove it now finally.

Subject: [PATCH 2854/3298] EDAC: Fix csrow size reported in sysfs

On csrow-based memory controllers, we combine the csrow size from both
channels and there's no need to do that again in csrow_size_show which
leads to double the size of a csrow.

Fix it.

Subject: [PATCH 2855/3298] EDAC: Fix mc size reported in sysfs

This is the complement to previous commit "EDAC: Fix csrow size
reported in sysfs". This fixes the memory controller size reporting on
csrow-based memory controllers. The csrow size is already combined for
both channels. Without this patch memory size is reported doubled.

Subject: [PATCH 2858/3298] MCE, AMD: Remove functional unit references

Having the functional unit names in each bank decode is only misleading
as this code supports multiple families and there's no guarantee the
mapping between FUs and MCE banks will stay the same.

And also, knowing the functional unit name doesn't help much since you
end up looking at the respective BKDG anyway.

So drop all FU references and use the MC bank numbers instead.

Subject: [PATCH 2859/3298] MCE, AMD: Dump CPU f/m/s triple with the error

It is very useful to have the family/model/stepping with the reported
error so dump it. This saves us asking the bug reporter about it.

Subject: [PATCH 2865/3298] cputime: Move thread_group_cputime() to sched code

thread_group_cputime() is a general cputime API that is not only
used by posix cpu timer. Let's move this helper to sched code.

Subject: [PATCH 2866/3298] cputime: Rename thread_group_times to
 thread_group_cputime_adjusted

We have thread_group_cputime() and thread_group_times(). The naming
doesn't provide enough information about the difference between
these two APIs.

To lower the confusion, rename thread_group_times() to
thread_group_cputime_adjusted(). This name better suggests that
it's a version of thread_group_cputime() that does some stabilization
on the raw cputime values. ie here: scale on top of CFS runtime
stats and bound lower value for monotonicity.

Subject: [PATCH 2867/3298] cputime: Consolidate cputime adjustment code

task_cputime_adjusted() and thread_group_cputime_adjusted()
essentially share the same code. They just don't use the same
source:

* The first function uses the cputime in the task struct and the
previous adjusted snapshot that ensures monotonicity.

* The second adds the cputime of all tasks in the group and the
previous adjusted snapshot of the whole group from the signal
structure.

Just consolidate the common code that does the adjustment. These
functions just need to fetch the values from the appropriate
source.

 }

As far as I can tell, the leak has been around since ~2003.

Subject: [PATCH 2870/3298] sctp: fix -ENOMEM result with invalid user space
 pointer in sendto() syscall

Consider the following program, that sets the second argument to the
sendto() syscall incorrectly:

 #include <string.h>
 #include <arpa/inet.h>
 #include <sys/socket.h>

 int main(void)
 {
         int fd;
         struct sockaddr_in sa;

         fd = socket(AF_INET, SOCK_STREAM, 132 /*IPPROTO_SCTP*/);
         if (fd < 0)
                 return 1;

         memset(&sa, 0, sizeof(sa));
         sa.sin_family = AF_INET;
         sa.sin_addr.s_addr = inet_addr("127.0.0.1");
         sa.sin_port = htons(11111);

         sendto(fd, NULL, 1, 0, (struct sockaddr *)&sa, sizeof(sa));

         return 0;
 }

We get -ENOMEM:

 $ strace -e sendto ./demo
 sendto(3, NULL, 1, 0, {sa_family=AF_INET, sin_port=htons(11111), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ENOMEM (Cannot allocate memory)

Propagate the error code from sctp_user_addto_chunk(), so that we will
tell user space what actually went wrong:

 $ strace -e sendto ./demo
 sendto(3, NULL, 1, 0, {sa_family=AF_INET, sin_port=htons(11111), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 EFAULT (Bad address)

Noticed while running Trinity (the syscall fuzzer).

Subject: [PATCH 2871/3298] sctp: Error in calculation of RTTvar

The calculation of RTTVAR involves the subtraction of two unsigned
numbers which
may causes rollover and results in very high values of RTTVAR when RTT > SRTT.
With this patch it is possible to set RTOmin = 1 to get the minimum of RTO at
4 times the clock granularity.

Change Notes:

v2)
        *Replaced abs() by abs64() and long by __s64, changed patch
description.

+TODOs
+-----
+1. Implement retries for RCODE_BUSY, RCODE_NO_ACK and RCODE_SEND_ERROR
+   - I/O is handled asynchronously which presents some issues when error
+     conditions occur.
+2. Implement _robust_ console on top of this. The existing prototype console
+   driver is not ready for the big leagues yet.
+3. Expose means of controlling attach/detach of peers via sysfs. Include
+   GUID-to-port matching/whitelist/blacklist.
+
+-- Issues with firewire stack --
+1. This driver uses the same unregistered vendor id that the firewire core does
+     (0xd00d1e). Perhaps this could be exposed as a define in
+     firewire-constants.h?
+2. MAX_ASYNC_PAYLOAD needs to be publicly exposed by core/ohci
+   - otherwise how will this driver know the max size of address window to
+     open for one packet write?
+3. Maybe device_max_receive() and link_speed_to_max_payload() should be
+     taken up by the firewire core?
+4. To avoid dropping rx data while still limiting the maximum buffering,
+     the size of the AR context must be known. How to expose this to drivers?
+5. Explore if bigger AR context will reduce RCODE_BUSY responses
+   (or auto-grow to certain max size -- but this would require major surgery
+    as the current AR is contiguously mapped)
+
+-- Issues with TTY core --
+  1. Hack for alternate device name scheme
+     - because udev no longer allows device renaming, devices should have
+       their proper names on creation. This is an issue for creating the
+       fwloop<n> device with the fwtty<n> devices because although duplicating
+       roughly the same operations as tty_port_register_device() isn't difficult,
+       access to the tty_class & tty_fops is restricted in scope.
+
+       This is currently being worked around in create_loop_device() by
+       extracting the tty_class ptr and tty_fops ptr from the previously created
+       tty devices. Perhaps an add'l api can be added -- eg.,
+       tty_{port_}register_named_device().

+/**
+ * The design basis for the DMA FIFO is to provide an output side that
+ * complies with the streaming DMA API design that can be DMA'd from directly
+ * (without additional copying), coupled with an input side that maintains a
+ * logically consistent 'apparent' size (ie, bytes in + bytes avail is static
+ * for the lifetime of the FIFO).
+ *
+ * DMA output transactions originate on a cache line boundary and can be
+ * variably-sized. DMA output transactions can be retired out-of-order but
+ * the FIFO will only advance the output in the original input sequence.
+ * This means the FIFO will eventually stall if a transaction is never retired.
+ *
+ * Chunking the output side into cache line multiples means that some FIFO
+ * memory is unused. For example, if all the avail input has been pended out,
+ * then the in and out markers are re-aligned to the next cache line.
+ * The maximum possible waste is
+ *     (cache line alignment - 1) * (max outstanding dma transactions)
+ * This potential waste requires additional hidden capacity within the FIFO
+ * to be able to accept input while the 'apparent' size has not been reached.
+ *
+ * Additional cache lines (ie, guard area) are used to minimize DMA
+ * fragmentation when wrapping at the end of the FIFO. Input is allowed into the
+ * guard area, but the in and out FIFO markers are wrapped when DMA is pended.

+ * fwserial_probe: bus probe function for firewire 'serial' unit devices
+ *
+ * A 'serial' unit device is created and probed as a result of:
+ * - declaring a ieee1394 bus id table for 'devices' matching a fabricated
+ *   'serial' unit specifier id
+ * - adding a unit directory to the config ROM(s) for a 'serial' unit
+ *
+ * The firewire core registers unit devices by enumerating unit directories
+ * of a node's config ROM after reading the config ROM when a new node is
+ * added to the bus topology after a bus reset.
+ *
+ * The practical implications of this are:
+ * - this probe is called for both local and remote nodes that have a 'serial'
+ *   unit directory in their config ROM (that matches the specifiers in
+ *   fwserial_id_table).
+ * - no specific order is enforced for local vs. remote unit devices
+ *
+ * This unit driver copes with the lack of specific order in the same way the

For TTY drivers that manage the port lifetime, the tty_port should

Subject: [PATCH 2891/3298] staging: gdm72xx: use %pI4 format to print IPv4
 address and remove last usage of NIP6

commit cf4ca4874fc45 removed the definition of NIPQUAD and NIPQUAD_FMT,
and NIP6 also is out of date.

commit 2874762b31d8d replace deprecated NIPQUAD marco to C code, but we can use %pI4 to
print IPv4 address more simply. And remove constant condition judge.

Because DEBUG_SDU is not defined in gdm_wimax.h, no error message when compiling.

From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:22:34 -0500
Subject: [PATCH 2909/3298] gpio: remove use of __devinit

CONFIG_HOTPLUG is going away as an option so __devinit is no longer
needed.

From d1723fa266aff677571cad0bac7203ed2e424823 Mon Sep 17 00:00:00 2001
From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:21:09 -0500
Subject: [PATCH 2931/3298] backlight: remove use of __devexit_p

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.

From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:24:21 -0500
Subject: [PATCH 2944/3298] mfd: remove use of __devinitdata

CONFIG_HOTPLUG is going away as an option so __devinitdata is no
longer needed.

From fd1091125a1d11fcc635749d0d3dec36904a7a48 Mon Sep 17 00:00:00 2001
From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:21:28 -0500
Subject: [PATCH 2947/3298] pwm: remove use of __devexit_p

CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.

From c3be1efd41a97f93be390240387d356a07b664c7 Mon Sep 17 00:00:00 2001
From: Bill Pemberton <wfp5p@virginia.edu>
Date: Mon, 19 Nov 2012 13:23:06 -0500
Subject: [PATCH 2951/3298] mmc: remove use of __devinit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CONFIG_HOTPLUG is going away as an option so __devinit is no longer
needed.

Subject: [PATCH 2968/3298] PCI: Move pci_uevent into pci-driver.c

With the demise of CONFIG_HOTPLUG as an option, the pci_uevent
function located in hotplug.c will now always be used and doesn't need
special treatment in the Makefile.  Move pci_uevent into pci-driver.c
and remove hotplug.c

As reported https://bugzilla.kernel.org/show_bug.cgi?id=51031, the UAS
driver causes problems and has been asked to be not built into any of
the major distributions.  To prevent users from running into problems
with it, and for distros that were not notified, just mark the whole
thing as broken.

of_parse_phandle() can therefore take a const pointer as well.

 constification

Commit c22618a1, "drivers/of: Constify device_node->name and
->path_component_name" changes device_node name to a const value, but
the PowerPC scom code still assigns it to a non-void field in
debugfs_blob_wrapper. The /right/ solution might be to change the
debugfs_blob_wrapper->data to also be const, but that is a bit
risky. Instead, cast the value to (void*). It is a bit ugly, but it
is the safest change until it can be investigated where
debugfs_blob_wrapper can be modified.

Subject: [PATCH 2984/3298] bonding: fix miimon and arp_interval delayed work
 race conditions

First I would give three observations which will be used later.
Observation 1: if (delayed_work_pending(wq)) cancel_delayed_work(wq)
 This usage is wrong because the pending bit is cleared just before the
 work's fn is executed and if the function re-arms itself we might end up
 with the work still running. It's safe to call cancel_delayed_work_sync()
 even if the work is not queued at all.
Observation 2: Use of INIT_DELAYED_WORK()
 Work needs to be initialized only once prior to (de/en)queueing.
Observation 3: IFF_UP is set only after ndo_open is called

Related race conditions:
1. Race between bonding_store_miimon() and bonding_store_arp_interval()
 Because of Obs.1 we can end up having both works enqueued.
2. Multiple races with INIT_DELAYED_WORK()
 Since the works are not protected by anything between INIT_DELAYED_WORK()
 and calls to (en/de)queue it is possible for races between the following
 functions:
 (races are also possible between the calls to INIT_DELAYED_WORK()
  and workqueue code)
 bonding_store_miimon() - bonding_store_arp_interval(), bond_close(),
			  bond_open(), enqueued functions
 bonding_store_arp_interval() - bonding_store_miimon(), bond_close(),
				bond_open(), enqueued functions
3. By Obs.1 we need to change bond_cancel_all()

Bugs 1 and 2 are fixed by moving all work initializations in bond_open
which by Obs. 2 and Obs. 3 and the fact that we make sure that all works
are cancelled in bond_close(), is guaranteed not to have any work
enqueued.
Also RTNL lock is now acquired in bonding_store_miimon/arp_interval so
they can't race with bond_close and bond_open. The opposing work is
cancelled only if the IFF_UP flag is set and it is cancelled
unconditionally. The opposing work is already cancelled if the interface
is down so no need to cancel it again. This way we don't need new
synchronizations for the bonding workqueue. These bugs (and fixes) are
tied together and belong in the same patch.
Note: I have left 1 line intentionally over 80 characters (84) because I
      didn't like how it looks broken down. If you'd prefer it otherwise,
      then simply break it.

Subject: [PATCH 2985/3298] bonding: make arp_ip_target parameter checks
 consistent with sysfs

The module can be loaded with arp_ip_target="255.255.255.255" which makes
 it impossible to remove as the function in sysfs checks for that value,
 so we make the parameter checks consistent with sysfs.

 v2: Fix formatting
 v3: Make description text < 75 columns

 bonding_store_slaves_active

Race between bonding_store_slaves_active() and slave manipulation
 functions. The bond_for_each_slave use in bonding_store_slaves_active()
 is not protected by any synchronization mechanism.
 NULL pointer dereference is easy to reach.
 Fixed by acquiring the bond->lock for the slave walk.

Subject: [PATCH 2987/3298] fs/buffer.c: make block-size be per-page and
 protected by the page lock

This makes the buffer size handling be a per-page thing, which allows us
to not have to worry about locking too much when changing the buffer
size.  If a page doesn't have buffers, we still need to read the block
size from the inode, but we can do that with ACCESS_ONCE(), so that even
if the size is changing, we get a consistent value.

This doesn't convert all functions - many of the buffer functions are
used purely by filesystems, which in turn results in the buffer size
being fixed at mount-time.  So they don't have the same consistency
issues that the raw device access can have.

Subject: [PATCH 2988/3298] blockdev: remove bd_block_size_semaphore again

This reverts the block-device direct access code to the previous
unlocked code, now that fs/buffer.c no longer needs external locking.

With this, fs/block_dev.c is back to the original version, apart from a
whitespace cleanup that I didn't want to revert.

Subject: [PATCH 2989/3298] direct-io: don't read inode->i_blkbits multiple
 times

Since directio can work on a raw block device, and the block size of the
device can change under it, we need to do the same thing that
fs/buffer.c now does: read the block size a single time, using
ACCESS_ONCE().

Reading it multiple times can get different results, which will then
confuse the code because it actually encodes the i_blksize in
relationship to the underlying logical blocksize.

Per Alan Cox, Nx586 did not support WP in supervisor mode, making it a
386 by Linux kernel standards.  As such, it is too unsupported now.

Subject: [PATCH 2999/3298] blkdev_max_block: make private to fs/buffer.c

We really don't want to look at the block size for the raw block device
accesses in fs/block-dev.c, because it may be changing from under us.
So get rid of the max_block logic entirely, since the caller should
already have done it anyway.

That leaves the only user of this function in fs/buffer.c, so move the
whole function there and make it static.

Subject: [PATCH 3000/3298] staging: comedi: addi_apci_2032: separate from
 addi_common.c

This driver is for a simple 32 channel digital output board. Using the
addi-data "common" code introduces a lot of bloat.

Copy the code in addi_common.c to this driver and remove the #include
that caused addi_common.c to be compiled with this driver. This will
allow removing the bloat.

Rename the attach_pci and detach functions so they have namespace
associated with this driver.

Reading the eeprom on the board supported by this driver is not
necessary. All the information required is in the boardinfo.

Remove the eeprom support code since it's not really interesting
or useful.

Subject: [PATCH 3007/3298] staging: comedi: addi_apci_2032: absorb
 i_APCI2032_Reset()

This is the only 'reset' function used by the driver, remove it
from the boardinfo and absorb the code from hwdrv_apci2032.c into
the driver.

Rename the CamelCase function i_ADDI_Reset() to apci2032_reset().

Subject: [PATCH 3008/3298] staging: comedi: addi_apci_2032: simplify the PCI
 bar reading

The board supported by this driver has a 93c76 eeprom. Knowing this
information allows simplifying the code that reads the PCI bars to
get the iobase address.

Also, since the 'dw_AiBase' is not ioremap'ed we can remove the iounmap
in the detach.

The i_IorangeBase[012], i_PCIEeprom, and pc_EepromChip data in the
boardinfo was only needed to work out the usage of the PCI bars.
This is no longer needed so remove the data.

Subject: [PATCH 3013/3298] staging: comedi: addi_apci_2032: only allocate
 needed subdevices

The addi-data "common" code always allocated 7 subdevices. This driver
only requires 2. Change the allocation and remove the unused subdevices.

Subject: [PATCH 3015/3298] staging: comedi: addi_apci_2032: cleanup the
 s->subdev_flags

The flags SDF_GROUND and SDF_COMMON only have meaning for analog
input/output subdevices. Remove these flags from the digital
output and timer subdevices in this driver.

The digital output subdevice does not need the SDF_READABLE flag.
Remove it.

Subject: [PATCH 3018/3298] staging: comedi: addi_apci_2032: fix
 i_APCI2032_ReadWatchdog()

This function is used by the watchdog subdevice to read the status of
the watchdog. Rename the CamelCase function to apci2032_wdog_insn_read
and fix the function to return the status value insn->n times like
the comedi core expects.

Subject: [PATCH 3019/3298] staging: comedi: addi_apci_2032: remove use of
 struct addi_private

The only data in addi_private used in this driver is:

tsk_Current - used with send_sig to signal userspace when an interrupt
has occurred. Interrupt support in this driver does not follow the
standard comedi API so this functionality is currently broken. This
will be addressed.

b_OutputMemoryStatus - used in the addi-data "common" code to enable
reading of the eeprom. Eeprom support is not needed by this driver
and has been removed.

Since this data is not needed, remove the use of struct addi_private.

Subject: [PATCH 3021/3298] staging: comedi: addi_apci_2032: fix the watchdog
 timer subdevice

The watchdog timer on this board functions exactly like the one on
the apci_1516 board. Fix the i_APCI2032_StartStopWriteWatchdog and
i_APCI2032_ConfigWatchdo functions so that the watchdog follows the
comedi API.

Rename the CamelCase function i_APCI2032_StartStopWriteWatchdog to
apci2032_wdog_insn_writ. This function is used to "ping" the watchdog.

Rename the CamelCase function i_APCI2032_ConfigWatchdog to
apci2032_wdog_insn_config. This function is used to enable/disable
the watchdog and set the timeout.

Subject: [PATCH 3023/3298] staging: comedi: addi_apci_2032: remove the timer
 s->range_table

The timer subdevice does not have a digital range. Its range of
0 to 0xff is the value used to set the reload timer.

Remove the setting of s->range_table. The comedi core will then
set it to range_unknown.

Subject: [PATCH 3025/3298] staging: comedi: addi_apci_2032: fix interrupt
 support

This board supports two interrupt sources:

VCC : detects when the external supply voltage drops below 5V
CC  : over temperature diagnostic

Currently the interrupt support is tied into the digital output
subdevice. It's also broken since it does not follow the comedi
API.

Create a new digital input subdevice to handle the interrupts.

Subject: [PATCH 3027/3298] staging: panel: pass correct lengths to
 keypad_send_key()

We changed the sizeof() statements in 429ccf058b "staging:panel: Fixed
coding conventions." so that they could fit inside the 80 character
line limit.  Unfortunately, the new sizeof() statements are a smaller
size.  This reverts it.

There isn't a nice way to stay within the 80 character limit without
a re-work so I've gone over.

Subject: [PATCH 3037/3298] gpio / ACPI: add ACPI support

Add support for translating ACPI GPIO pin numbers to Linux GPIO API pins.
Needs a gpio controller driver with the acpi handler hook set.

Drivers can use acpi_get_gpio() to translate ACPI5 GpioIO and GpioInt
resources to Linux GPIO's.

Subject: [PATCH 3038/3298] spi / ACPI: add ACPI enumeration support

ACPI 5 introduced SPISerialBus resource that allows us to enumerate and
configure the SPI slave devices behind the SPI controller. This patch adds
support for this to the SPI core.

In addition we bind ACPI nodes to SPI devices. This makes it possible for
the slave drivers to get the ACPI handle for further configuration.

Subject: [PATCH 3039/3298] ACPI: do acpisleep dmi check when CONFIG_ACPI_SLEEP
 is set

The current acpisleep DMI checks only run when CONFIG_SUSPEND is set.
And this may break hibernation on some platforms when CONFIG_SUSPEND
is cleared.

Move acpisleep DMI check into #ifdef CONFIG_ACPI_SLEEP instead.

[rjw: Added acpi_sleep_dmi_check() and rebased on top of earlier
 patches adding entries to acpisleep_dmi_table[].]

Subject: [PATCH 3040/3298] ACPI / video: Add "Asus UL30VT" to ACPI video
 detect blacklist

The ACPI video driver can't control backlight correctly on
Asus UL30VT.  Vendor driver (asus-laptop) can work.  This patch is to
add "Asus UL30VT" to ACPI video detect blacklist in order to use
asus-laptop for video control on the "Asus UL30VT" rather than ACPI
video driver.

Subject: [PATCH 3041/3298] ACPI / PNP: Do not crash due to stale pointer use
 during system resume

During resume from system suspend the 'data' field of
struct pnp_dev in pnpacpi_set_resources() may be a stale pointer,
due to removal of the associated ACPI device node object in the
previous suspend-resume cycle.  This happens, for example, if a
dockable machine is booted in the docking station and then suspended
and resumed and suspended again.  If that happens,
pnpacpi_build_resource_template() called from pnpacpi_set_resources()
attempts to use that pointer and crashes.

However, pnpacpi_set_resources() actually checks the device's ACPI
handle, attempts to find the ACPI device node object attached to it
and returns an error code if that fails, so in fact it knows what the
correct value of dev->data should be.  Use this observation to update
dev->data with the correct value if necessary and dump a call trace
if that's the case (once).

We still need to fix the root cause of this issue, but preventing
systems from crashing because of it is an improvement too.

Currently the platform data for the ad7793 consist just out of the raw default
register settings. This has some downsides, for one we actually don't want to
make all bits configurable and secondly not all register settings are actually
valid. This patch exposes all the options which should be configurable via
platform data as induvidual platform data struct fields. This also allows us to
document the different settings via proper kernel doc.

Subject: [PATCH 3047/3298] staging:iio:ad7793: Rework regulator handling

Rework the regulator handling of the driver to match more closely what we do in
other drivers. Make the regulator non-optional if a external reference is used.
Also dispose the option of specifying the reference voltage via platform data.

Subject: [PATCH 3048/3298] staging:iio:ad7793: Move register definitions from
 header to source

The only user of the register definitions is the driver itself, so move them
from the header file to the driver source file. The header file now only
contains the platform data struct.

Subject: [PATCH 3049/3298] staging:iio:ad7793: Implement stricter id checking

Instead of checking whether the id of the current device matches the id of any
device supported by the driver, check whether it matches the id of the device
which the driver was instantiated for. This makes sure that the driver is not
accidentally instantiated for the wrong device.

Subject: [PATCH 3051/3298] iio:ad7793: Add support for the ad7798 and ad7799

The ad7798 and ad7799 are similar to the ad7792 and ad7793 but are missing some
features like the temperature sensor, being able to use an external clocksource
and a few other things. This patch adds a new 'flags' fields to the chip_info
struct which allows to specify which features a certain chip variant supports.
The setup code will then ignore any platform data fields which are related to
non supported features.

Subject: [PATCH 3052/3298] iio:ad7793: Add support for the ad7796 and ad7797

The ad7796 and ad7797 are similar to the ad7792 and ad7793 but only have a
single differential input instead of two. Also some other features are missing
like the programmable gain amplifier and also not all sampling frequencies
supported by the ad7792/ad7793 are supported by the ad7796/ad7797. This patch
adds new feature flags for the features not present in the ad7796/ad7797. The
patch also adds a struct iio_info field to the chip_info struct, this becomes
necessary since the ad7796/ad7797 needs a special set of sysfs attributes.

Subject: [PATCH 3054/3298] iio:gyro: adis16136: divide by zero in
 write_frequency()

It's slightly cleaner to use kstrtouint() because we pass unsigned ints
to adis16136_set_freq().  On 64 bit systems, if the user passed LONG_MIN
then it we would get past the test against zero but crash in
adis16136_set_freq() because we truncate the high bits away.

Subject: [PATCH 3055/3298] iio:imu: adis16480: show_firmware() buffer too
 small

Smatch complains that snprintf() returns the number of characters,
not counting the NUL terminator, which *would* have been printed if
there were enough space.  In other words the return value could be more
than sizeof(buf).

In this case, we are printing something like "ff.ff\n" which is at most
6 characters and a NUL so that's not an issue.  I changed snprintf() to
scnprintf() to silence the warning.

But since the buffer doesn't include space for the NUL terminator, we
need to make it bigger or the "\n" will be truncated off.

Subject: [PATCH 3058/3298] ring-buffer: Fix NULL pointer if rb_set_head_page()
 fails

The function rb_set_head_page() searches the list of ring buffer
pages for a the page that has the HEAD page flag set. If it does
not find it, it will do a WARN_ON(), disable the ring buffer and
return NULL, as this should never happen.

But if this bug happens to happen, not all callers of this function
can handle a NULL pointer being returned from it. That needs to be
fixed.

Subject: [PATCH 3059/3298] ring-buffer: Fix race between integrity check and
 readers

The function rb_check_pages() was added to make sure the ring buffer's
pages were sane. This check is done when the ring buffer size is modified
as well as when the iterator is released (closing the "trace" file),
as that was considered a non fast path and a good place to do a sanity
check.

The problem is that the check does not have any locks around it.
If one process were to read the trace file, and another were to read
the raw binary file, the check could happen while the reader is reading
the file.

The issues with this is that the check requires to clear the HEAD page
before doing the full check and it restores it afterward. But readers
require the HEAD page to exist before it can read the buffer, otherwise
it gives a nasty warning and disables the buffer.

By adding the reader lock around the check, this keeps the race from
happening.

return value which was also missed by this reviewer until today.

That return value is used by compaction when adding pages to a list of
isolated free pages and without this follow-up fix, there is a risk of
free list corruption.

I enable CONFIG_DEBUG_VIRTUAL and CONFIG_SPARSEMEM_VMEMMAP, when doing
memory hotremove, there is a kernel BUG at arch/x86/mm/physaddr.c:20.

It is caused by free_section_usemap()->virt_to_page(), virt_to_page() is
only used for kernel direct mapping address, but sparse-vmemmap uses
vmemmap address, so it is going wrong here.

allocation.  This gets kswapd stuck in an endless loop over a small
zone, like the DMA zone, where the high watermark is smaller than the
compaction requirement.

Add a function, zone_balanced(), that checks the watermark, and, for
higher order allocations, if compaction has enough free memory.  Then
use it uniformly to check for balanced zones.

This makes sure that when the compaction watermark is not met, at least
reclaim happens and progress is made - or the zone is declared
unreclaimable at some point and skipped entirely.

Subject: [PATCH 3064/3298] mm: avoid waking kswapd for THP allocations when
 compaction is deferred or contended

With "mm: vmscan: scale number of pages reclaimed by reclaim/compaction
based on failures" reverted, Zdenek Kabelac reported the following

  Hmm,  so it's just took longer to hit the problem and observe
  kswapd0 spinning on my CPU again - it's not as endless like before -
  but still it easily eats minutes - it helps to turn off  Firefox
  or TB  (memory hungry apps) so kswapd0 stops soon - and restart
  those apps again.  (And I still have like >1GB of cached memory)

  kswapd0         R  running task        0    30      2 0x00000000
  Call Trace:
    preempt_schedule+0x42/0x60
    _raw_spin_unlock+0x55/0x60
    put_super+0x31/0x40
    drop_super+0x22/0x30
    prune_super+0x149/0x1b0
    shrink_slab+0xba/0x510

The sysrq+m indicates the system has no swap so it'll never reclaim
anonymous pages as part of reclaim/compaction.  That is one part of the
problem but not the root cause as file-backed pages could also be
reclaimed.

The likely underlying problem is that kswapd is woken up or kept awake
for each THP allocation request in the page allocator slow path.

If compaction fails for the requesting process then compaction will be
deferred for a time and direct reclaim is avoided.  However, if there
are a storm of THP requests that are simply rejected, it will still be
the the case that kswapd is awake for a prolonged period of time as
pgdat->kswapd_max_order is updated each time.  This is noticed by the
main kswapd() loop and it will not call kswapd_try_to_sleep().  Instead
it will loopp, shrinking a small number of pages and calling
shrink_slab() on each iteration.

This patch defers when kswapd gets woken up for THP allocations.  For
!THP allocations, kswapd is always woken up.  For THP allocations,
kswapd is woken up iff the process is willing to enter into direct
reclaim/compaction.

Subject: [PATCH 3067/3298] kbuild: centralize .dts->.dtb rule

All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file. This
difference will be eliminated arch-by-arch in future patches.

MIPS is the exception here; it already uses the exact same rule as the
new common rule, so the duplicate is removed in this patch to avoid any
conflict. arch/mips changes courtesy of Ralf Baechle.

Update Documentation/kbuild to remove the explicit call to cmd_dtc from
the example, now that the rule exists in a centralized location.

From 91d1aa43d30505b0b825db8898ffc80a8eca96c7 Mon Sep 17 00:00:00 2001
From: Frederic Weisbecker <fweisbec@gmail.com>
Date: Tue, 27 Nov 2012 19:33:25 +0100
Subject: [PATCH 3068/3298] context_tracking: New context tracking susbsystem

Create a new subsystem that probes on kernel boundaries
to keep track of the transitions between level contexts
with two basic initial contexts: user or kernel.

This is an abstraction of some RCU code that use such tracking
to implement its userspace extended quiescent state.

We need to pull this up from RCU into this new level of indirection
because this tracking is also going to be used to implement an "on
demand" generic virtual cputime accounting. A necessary step to
shutdown the tick while still accounting the cputime.

Subject: [PATCH 3069/3298] init.h: Remove __dev* sections from the kernel

With the recent work to remove CONFIG_HOTPLUG, we are starting to get a
bunch of __devinit section warnings, despite CONFIG_HOTPLUG always being
enabled.  So, stop marking the sections entirely, by defining them away
the section markings in init.h

Subject: [PATCH 3071/3298] x86, fpu: Avoid FPU lazy restore after suspend

When a cpu enters S3 state, the FPU state is lost.
After resuming for S3, if we try to lazy restore the FPU for a process running
on the same CPU, this will result in a corrupted FPU context.

Ensure that "fpu_owner_task" is properly invalided when (re-)initializing a CPU,
so nobody will try to lazy restore a state which doesn't exist in the hardware.

Tested with a 64-bit kernel on a 4-core Ivybridge CPU with eagerfpu=off,
by doing thousands of suspend/resume cycles with 4 processes doing FPU
operations running. Without the patch, a process is killed after a
few hundreds cycles by a SIGFPE.

Commit dece904d (gpio: pl061: use chained_irq_* functions in irq
handler) introduced chained_irq_enter/exit, which is only
available for arch/arm and the driver won't compile elsewhere.

The dependency is thus made explicit, because AMBA is used in the x86
world by a PCI-to-AMBA bridge, to be submitted.

Subject: [PATCH 3077/3298] workqueue: mod_delayed_work_on() shouldn't queue
 timer on 0 delay

8376fe22c7 ("workqueue: implement mod_delayed_work[_on]()")
implemented mod_delayed_work[_on]() using the improved
try_to_grab_pending().  The function is later used, among others, to
replace [__]candel_delayed_work() + queue_delayed_work() combinations.

Unfortunately, a delayed_work item w/ zero @delay is handled slightly
differently by mod_delayed_work_on() compared to
queue_delayed_work_on().  The latter skips timer altogether and
directly queues it using queue_work_on() while the former schedules
timer which will expire on the closest tick.  This means, when @delay
is zero, that [__]cancel_delayed_work() + queue_delayed_work_on()
makes the target item immediately executable while
mod_delayed_work_on() may induce delay of upto a full tick.

This somewhat subtle difference breaks some of the converted users.
e.g. block queue plugging uses delayed_work for deferred processing
and uses mod_delayed_work_on() when the queue needs to be immediately
unplugged.  The above problem manifested as noticeably higher number
of context switches under certain circumstances.

The difference in behavior was caused by missing special case handling
for 0 delay in mod_delayed_work_on() compared to
queue_delayed_work_on().  Joonsoo Kim posted a patch to add it -
("workqueue: optimize mod_delayed_work_on() when @delay == 0")[1].
The patch was queued for 3.8 but it was described as optimization and
I missed that it was a correctness issue.

As both queue_delayed_work_on() and mod_delayed_work_on() use
__queue_delayed_work() for queueing, it seems that the better approach
is to move the 0 delay special handling to the function instead of
duplicating it in mod_delayed_work_on().

Fix the problem by moving 0 delay special case handling from
queue_delayed_work_on() to __queue_delayed_work().  This replaces
Joonsoo's patch.

Subject: [PATCH 3078/3298] tcp: fix crashes in do_tcp_sendpages()

Recent network changes allowed high order pages being used
for skb fragments.

This uncovered a bug in do_tcp_sendpages() which was assuming its caller
provided an array of order-0 page pointers.

We only have to deal with a single page in this function, and its order
is irrelevant.

Subject: [PATCH 3080/3298] open*(2) compat fixes (s390, arm64)

The usual rules for open()/openat()/open_by_handle_at() are
 1) native 32bit - don't force O_LARGEFILE in flags
 2) native 64bit - force O_LARGEFILE in flags
 3) compat on 64bit host - as for native 32bit
 4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for
    native 64bit

There are only two exceptions - s390 compat has open() forcing
O_LARGEFILE and arm64 compat has open_by_handle_at() doing the same
thing.  The same binaries on native host (s390/31 and arm resp.) will
*not* force O_LARGEFILE, so IMO both are emulation bugs.

Objections? The fix is obvious...

Subject: [PATCH 3085/3298] Revert "sched, autogroup: Stop going ahead if
 autogroup is disabled"

This reverts commit 800d4d30c8f20bd728e5741a3b77c4859a613f7c.

Between commits 8323f26ce342 ("sched: Fix race in task_group()") and
800d4d30c8f2 ("sched, autogroup: Stop going ahead if autogroup is
disabled"), autogroup is a wreck.

With both applied, all you have to do to crash a box is disable
autogroup during boot up, then reboot..  boom, NULL pointer dereference
due to commit 800d4d30c8f2 not allowing autogroup to move things, and
commit 8323f26ce342 making that the only way to switch runqueues:

Subject: [PATCH 3086/3298] [parisc] open(2) compat bug

In commit 9d73fc2d641f ("open*(2) compat fixes (s390, arm64)") I said:
>
> 	The usual rules for open()/openat()/open_by_handle_at() are
> 1) native 32bit - don't force O_LARGEFILE in flags
> 2) native 64bit - force O_LARGEFILE in flags
> 3) compat on 64bit host - as for native 32bit
> 4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for native 64bit
>
> There are only two exceptions - s390 compat has open() forcing O_LARGEFILE and
> arm64 compat has open_by_handle_at() doing the same thing.  The same binaries
> on native host (s390/31 and arm resp.) will *not* force O_LARGEFILE, so IMO
> both are emulation bugs.

Three exceptions, actually - parisc open() is another case like that.
Native 32bit won't force O_LARGEFILE, the same binary on parisc64 will.

Subject: [PATCH 3089/3298] sparc: Fix piggyback with newer binutils.

Newer versions of binutils mark '_end' as 'B' instead of 'A' for
whatever reason.

To be honest, the piggyback code doesn't actually care what kind
of symbol _start and _end are, it just wants to find them and
record the address.

So remove the type from the match strings.

Subject: [PATCH 3093/3298] microblaze: use new common dtc rule

The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes microblaze to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.

This requires moving parts of arch/microblaze/boot/Makefile into newly
created arch/microblaze/boot/dts/Makefile, and updating
arch/microblaze/Makefile to call the new Makefile. linked_dtb.S is also
moved into boot/dts/ since it's used by rules that were moved.

As ubi_self_check_all_ff() might sleep we are not allowed
to call it from atomic context.
For now we call it only from ubi_wl_get_peb().
There are some code paths where it would also make sense,
but these paths are currently atomic and only enabled
when fastmap is used.

Subject: [PATCH 3097/3298] megaraid: fix BUG_ON() from incorrect use of
 delayed work

megaraid use INIT_WORK to declare a hotplug_work, but cast the
hotplug_work from work_struct to delayed_work and
schedule_delayed_work on it.  This is very dangerous, as other part of
delayed_work might be kernel memories allocated by others.

With commit 8852aac ("workqueue: mod_delayed_work_on() shouldn't queue
timer on 0 delay"), schedule_delayed_work() will check dwork->timer
before queue_work even when @delay is 0, this causes megaraid code to
hit the BUG_ON() in workqueue code.  Change megaraid code to use
delayed work.

Subject: [PATCH 3098/3298] MIPS: Avoid mcheck by flushing page range in
 huge_ptep_set_access_flags()

Problem:

1) Huge page mapping of anonymous memory is initially invalid.  Will be
   faulted in by copy-on-write mechanism.

2) Userspace attempts store at the end of the huge mapping.

3) TLB Refill exception handler fill TLB with a normal (4K sized)
   invalid page at the end of the huge mapping virtual address range.

4) Userspace restarted, and re-attempts the store at the end of the
   huge mapping.

5) Page from #3 is invalid, we get a fault and go to the hugepage
   fault handler.  This tries to map a huge page and calls
   huge_ptep_set_access_flags() to install the mapping.

6) We just call the generic ptep_set_access_flags() to set up the page
   tables, but the flush there assumes a normal (4K sized) page and
   only tries to flush the first part of the huge page virtual address
   out of the TLB, since the existing entry from step #3 doesn't
   conflict, nothing is flushed.

7) We attempt to load the mapping into the TLB, but because it
   conflicts with the entry from step #3, we get a Machine Check
   exception.

The fix: Flush the entire rage covered by the huge page in
huge_ptep_set_access_flags(), and remove the optimization in
local_flush_tlb_range() so that the flush actually does the correct
thing.

Subject: [PATCH 3099/3298] workqueue: convert BUG_ON()s in
 __queue_delayed_work() to WARN_ON_ONCE()s

8852aac25e ("workqueue: mod_delayed_work_on() shouldn't queue timer on
0 delay") unexpectedly uncovered a very nasty abuse of delayed_work in
megaraid - it allocated work_struct, casted it to delayed_work and
then pass that into queue_delayed_work().

Previously, this was okay because 0 @delay short-circuited to
queue_work() before doing anything with delayed_work.  8852aac25e
moved 0 @delay test into __queue_delayed_work() after sanity check on
delayed_work making megaraid trigger BUG_ON().

Although megaraid is already fixed by c1d390d8e6 ("megaraid: fix
BUG_ON() from incorrect use of delayed work"), this patch converts
BUG_ON()s in __queue_delayed_work() to WARN_ON_ONCE()s so that such
abusers, if there are more, trigger warning but don't crash the
machine.

Subject: [PATCH 3100/3298] vfs: avoid "attempt to access beyond end of device"
 warnings

The block device access simplification that avoided accessing the (racy)
block size information (commit bbec0270bdd8: "blkdev_max_block: make
private to fs/buffer.c") no longer checks the maximum block size in the
block mapping path.

That was _almost_ as simple as just removing the code entirely, because
the readers and writers all check the size of the device anyway, so
under normal circumstances it "just worked".

However, the block size may be such that the end of the device may
straddle one single buffer_head.  At which point we may still want to
access the end of the device, but the buffer we use to access it
partially extends past the end.

The 'bd_set_size()' function intentionally sets the block size to avoid
this, but mounting the device - or setting the block size by hand to
some other value - can modify that block size.

So instead, teach 'submit_bh()' about the special case of the buffer
head straddling the end of the device, and turning such an access into a
smaller IO access, avoiding the problem.

This, btw, also means that unlike before, we can now access the whole
device regardless of device block size setting.  So now, even if the
device size is only 512-byte aligned, we can read and write even the
last sector even when having a much bigger block size for accessing the
rest of the device.

So with this, we could now get rid of the 'bd_set_size()' block size
code entirely - resulting in faster IO for the common case - but that
would be a separate patch.

 points.

By using the native syscall entry point the kernel was also expecting
64-bit iovec structures.

This is broken since ddd9e91b71072b8ebe89311c3a44b077defa1756 [preadv/
pwritev: MIPS: Add preadv(2) and pwritev(2) syscalls.] which originally
added these two syscalls.  I walked through piles of code, including
libc and couldn't find anything that would have worked around the issue
so this change the API to what it should always have been.

Noticed and patch suggested by Al Viro.

This fixes a bit error in the U8500 clock implementation: the
unused p2_pclk12 registered at bit 12 in periphereral group 6
was defined as using bit 11 rather than bit 12.

When walking over and disabling the unused clocks in the tree
at late init time, p2_pclk12 was disabled, by effectively
clearing the but for p2_pclk11 instead of bit 12 as it should
have, thus disabling gpio block 6 and 7.

Norbert reported:
"3.7-rc6 booted with nmi_watchdog=0 fails to suspend to RAM or
 offline CPUs. It's reproducable with a KVM guest and physical
 system."

The reason is that commit bcd951cf(watchdog: Use hotplug thread
infrastructure) missed to take this into account. So the cpu offline
code gets stuck in the teardown function because it accesses non
initialized data structures.

Add a check for watchdog_enabled into that path to cure the issue.

Don't use enum-type bitfields in the module signature info block as we can't be
certain how the compiler will handle them.  As I understand it, it is arch
dependent, and it is possible for the compiler to rearrange them based on
endianness and to insert a byte of padding to pad the three enums out to four
bytes.

Instead use u8 fields for these, which the compiler should emit in the right
order without padding.

Subject: [PATCH 3111/3298] hwmon: (ads7828) driver cleanup

As there is no reliable way to identify the chip, it is preferable to
remove the detect callback, to avoid misdetection.

Module parameters are not worth it here, so let's get rid of them and
add an ads7828_platform_data structure instead.

Clean the code by removing unused macros, fixing coding style issues,
avoiding function prototypes and using convenient macros such as
module_i2c_driver().

 The chip also has the facility to use an external voltage reference.  This
 may be required if your hardware supplies the ADS7828 from a 5V supply, see
 the datasheet for more details.

+There is no reliable way to identify this chip, so the driver will not scan

Subject: [PATCH 3112/3298] hwmon: (ads7828) add support for ADS7830

The ADS7830 device is almost the same as the ADS7828,
except that it does 8-bit sampling, instead of 12-bit.
This patch extends the ads7828 driver to support this chip.

Subject: [PATCH 3114/3298] hwmon: (coretemp) Drop dependency on PCI for TjMax
 detection on Atom CPUs

So far, we use the NM10 Express Chipset PCI chip ID to detect TjMax for
Atom CPUs with model 0x1c. As it turns out, we can use the CPU stepping
(x86_mask) for the same purpose; stepping is 10 for all model 0x1c CPUs
with TjMax of 100 degrees C. This was verified by checking the output of
/proc/cpuinfo for the respective CPUs (D4xx, D5xx, N4xx, N5xx).

Other CPUs currently covered by the same code (Exx, Z6xx, Z2460) are not
supported by the NM10 Express Chipset. Most of those CPUs have TjMax of 90
degrees C, except for E6xxT models which have a TjMax of 110 degrees C.
E6xxT CPUs can however not be detected by software.

Calculate TjMax for Atom CPUs as follows. Note that the listed values are not
correct in some cases (230, 330). tjmax_table is used for those to override
the default values.

ID	Stepping	TjMax		Models
0x1c	10		100		D4xx, N4xx, D5xx, N5xx
0x1c	not 10		90		Z5xx, N2xx, 230, 330, others
0x26	-		90		Atom Tunnel Creek (Exx),
					Lincroft (Z6xx)
0x27	-		90		Atom Medfield (Z2460)
0x36	-		100		Atom Cedar Trail (N2xxx, D2xxx)

Also drop the module dependency on PCI.

+Description
+-----------
+
+The DA9055 provides an Analogue to Digital Converter (ADC) with 10 bits
+resolution and track and hold circuitry combined with an analogue input
+multiplexer. The analogue input multiplexer will allow conversion of up to 5
+different inputs. The track and hold circuit ensures stable input voltages at
+the input of the ADC during the conversion.
+
+The ADC is used to measure the following inputs:
+Channel 0: VDDOUT - measurement of the system voltage
+Channel 1: ADC_IN1 - high impedance input (0 - 2.5V)
+Channel 2: ADC_IN2 - high impedance input (0 - 2.5V)
+Channel 3: ADC_IN3 - high impedance input (0 - 2.5V)
+Channel 4: Internal Tjunc. - sense (internal temp. sensor)
+
+By using sysfs attributes we can measure the system voltage VDDOUT,
+chip junction temperature and auxiliary channels voltages.
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled in a AUTO mode it can be manually sampled too and results
+are stored in a 10 bit ADC.
+
+The system voltage is calculated as:
+	Milli volt = ((ADC value * 1000) / 85) + 2500
+
+The voltages on ADC channels 1, 2 and 3 are calculated as:
+	Milli volt = (ADC value * 1000) / 102
+
+Temperature Monitoring
+----------------------
+
+Temperatures are sampled by a 10 bit ADC.  Junction temperatures
+are monitored by the ADC channels.
+
+The junction temperature is calculated:
+	Degrees celsius = -0.4084 * (ADC_RES - T_OFFSET) + 307.6332
+The junction temperature attribute is supported by the driver.

Subject: [PATCH 3123/3298] MIPS: Fix endless loop when processing signals for
 kernel tasks

The problem occurs [1] when a kernel-mode task returns from a system
call with a pending signal.

A real-life scenario is a child of 'khelper' returning from a failed
kernel_execve() in ____call_usermodehelper() [ kernel/kmod.c ].
kernel_execve() fails due to a pending SIGKILL, which is the result of
"kill -9 -1" (at least, busybox's init does it upon reboot).

The loop is as follows:

* syscall_exit_work:
 - work_pending:            // start_of_the_loop
 - work_notifysig:
   - do_notify_resume()
     - do_signal()
       - if (!user_mode(regs)) return;
 - resume_userspace         // TIF_SIGPENDING is still set
 - work_pending             // so we call work_pending => goto
                            // start_of_the_loop

More information can be found in another LKML thread:
http://www.serverphorums.com/read.php?12,457826

[1] The problem was also reproduced on !CONFIG_VM86 x86, and the
following fix was accepted.

Subject: [PATCH 3124/3298] of/vendor-prefixes: add Imagination Technologies

The "powervr" prefix which is currently described as "Imagination
Technologies" isn't really appropriate for non-PowerVR hardware, so
deprecate it, changing the description of "powervr" to "PowerVR
(deprecated, use img)", and add a separate "img" prefix for "Imagination
Technologies Ltd.".

The vmmc regulator enable in sdhci_add_host is NOT necessary since
it can be enabled during mmc_power_up by function mmc_regulator_set_ocr.
And this extra enable will make regulator_enable/regulator_disable
unbalanced. Consequently, vmmc can't be disabled during mmc_power_off.

Also, if the vqmmc regulator exists, it should be enabled regardless it

Subject: [PATCH 3135/3298] mmc: dw_mmc: use helper macro
 module_platform_driver()

Since v3.2 we have nice macro to define the platform driver's init and exit
calls. This patch simplifies the dw_mmc platform driver by using that macro.

Subject: [PATCH 3136/3298] mmc: mxcmmc: fix SD cards not being detected
 sometimes.

When a SD card is initialized some data transfers of 64 and 8 bytes
are issued. It seems the DMA has some problems dealing with these kind
of "short" transfers, leading sometimes to the SD card not being detected.

In order to solve this problem, do not use DMA for transfer sizes lower
than the sector size.

-   This is the AT91 MCI driver that has been tested with both MMC cards
-   and SD-cards.  Boards that support write protect are now supported.
-   The CCAT91SBC001 board does not support SD cards.
-
-   The three entry points are at91_mci_request, at91_mci_set_ios
-   and at91_mci_get_ro.
-
-   SET IOS
-     This configures the device to put it into the correct mode and clock speed
-     required.
-
-   MCI REQUEST
-     MCI request processes the commands sent in the mmc_request structure. This
-     can consist of a processing command and a stop command in the case of
-     multiple block transfers.
-
-     There are three main types of request, commands, reads and writes.
-
-     Commands are straight forward. The command is submitted to the controller and
-     the request function returns. When the controller generates an interrupt to indicate
-     the command is finished, the response to the command are read and the mmc_request_done
-     function called to end the request.
-
-     Reads and writes work in a similar manner to normal commands but involve the PDC (DMA)
-     controller to manage the transfers.
-
-     A read is done from the controller directly to the scatterlist passed in from the request.
-     Due to a bug in the AT91RM9200 controller, when a read is completed, all the words are byte
-     swapped in the scatterlist buffers.  AT91SAM926x are not affected by this bug.
-
-     The sequence of read interrupts is: ENDRX, RXBUFF, CMDRDY
-
-     A write is slightly different in that the bytes to write are read from the scatterlist
-     into a dma memory buffer (this is in case the source buffer should be read only). The
-     entire write buffer is then done from this single dma memory buffer.
-
-     The sequence of write interrupts is: ENDTX, TXBUFE, NOTBUSY, CMDRDY
-
-   GET RO
-     Gets the status of the write protect pin, if available.

From e95baf132f9709b86721a562210403473ef72249 Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Thu, 8 Nov 2012 14:26:11 +0000
Subject: [PATCH 3141/3298] mmc: dw_mmc: fix more const pointer warnings

The patch "dw_mmc: fix multiple drv_data NULL dereferences" has
unfortunately clashed with my "mmc: dw_mmc: constify dw_mci_idmac_ops
in exynos back-end" patch, causing new warnings to appear.

This should hopefully fix the issue for good.

Subject: [PATCH 3142/3298] mmc: core: Fix some driver hangs when dealing with
 broken devices

There are infinite loops in the mmc code that can be caused by bad
hardware.  The code will loop forever if the device never comes back
from program mode, R1_STATE_PRG, and it is not ready for data,
R1_READY_FOR_DATA.

A long timeout is added to prevent the code from looping forever.
The timeout will occur if the device never comes back from program
state or the device never becomes ready for data.

It's not clear whether the timeout will do more than log a pr_err()
and then start a fresh hang all over again.  We may need to extend
this patch later to perform some kind of reset of the device (is
that possible?) or rejection of new I/O to the device.

Subject: [PATCH 3143/3298] mmc: sdio: Use multiple scatter/gather list

Before this patch, we always used only single sg entry for SDIO transfer.
This patch switches to using multiple sg entries. In the case of dwmci,
it supports only up to 4KB size per single sg entry. So if we want to
transfer more than 4KB, we should send more than 1 command.

When we tested before applying this patch, it took around 335 us for
5K(5120) bytes transfer with dwmci controller. After applying this patch,
it takes 242 us for 5K bytes. So this patch makes around 38% performance
improvement for 5K bytes transfer. If the transfer size is bigger, then
the performance improvement ratio will be increased.

Subject: [PATCH 3146/3298] mmc: sdhci-pxav3: Add base clock quirk

Enable the quirk SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN since
SD_CAPABILITIES_1[15:8](BASE_FREQ) can't get correct base clock value.
It returns a fixed pre-set value like 200 on some sdhci-pxav3 based
platforms like MMP3 while return 0 on the other sdhci-pxav3 based
platforms.  So we enable the quirk and get the base clock via function
get_max_clock. Also add get_max_clock.

Subject: [PATCH 3147/3298] mmc: host: Make UHS timing values fully unique

Both of MMC_TIMING_LEGACY and MMC_TIMING_UHS_SDR12 are defined
to 0. And ios->timing is set to MMC_TIMING_LEGACY during power up.
But set_ios can't distinguish these two timing if host support
spec 3.0. Just adjust timing values to be different can resolve
this issue without any other impact.

Subject: [PATCH 3153/3298] mmc: SD/MMC Host Controller for Wondermedia
 WM8505/WM8650

This patch adds support for the SD/MMC host controller found
on Wondermedia 8xxx series SoCs, currently supported under
arm/arch-vt8500.

A binding document is also included, based on mmc.txt with
additional properties.

+* Wondermedia WM8505/WM8650 SD/MMC Host Controller
+
+This file documents differences between the core properties described
+by mmc.txt and the properties used by the wmt-sdmmc driver.
+
+Required properties:
+- compatible: Should be "wm,wm8505-sdhc".
+- interrupts: Two interrupts are required - regular irq and dma irq.
+
+Optional properties:
+- sdon-inverted: SD_ON bit is inverted on the controller
+
+Examples:
+
+sdhc@d800a000 {
+	compatible = "wm,wm8505-sdhc";
+	reg = <0xd800a000 0x1000>;
+	interrupts = <20 21>;
+	clocks = <&sdhc>;
+	bus-width = <4>;
+	sdon-inverted;
+};

Date: Tue, 20 Nov 2012 08:24:32 -0500
Subject: [PATCH 3154/3298] mmc: sdhci: Use regulator min/max voltage range
 according to spec

For regulator vmmc/vmmcq, use voltage range as below
3.3v/3.0v: (2.7v, 3.6v)
1.8v: (1.7v, 1.95v)
Original code uses the precise value which may fail in regulator
driver if it does NOT support the precise voltage.

Subject: [PATCH 3160/3298] mmc: omap_hsmmc: Fix Oops in case of data errors

ae4bf788ee9 ("mmc: omap_hsmmc: consolidate error report handling of HSMMC
IRQ") sets both end_cmd and end_trans to 1.

Setting end_cmd to 1 for Data Timeout/CRC leads to NULL pointer dereference of
host->cmd as the command complete has previously been handled.
Set end_cmd only in case of command Timeout/CRC.

Moreover host->cmd->error should not be updated on data error case, only
host->data->error needs to be updated.

Subject: [PATCH 3163/3298] mmc: omap_hsmmc: Enable HSPE bit for high speed
 cards

HSMMC IP on AM33xx need a special setting to handle High-speed cards.
Other platforms like TI81xx, OMAP4 may need this as-well. This depends
on the HSMMC IP timing closure done for the high speed cards.

From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation):

The MMC/SD/SDIO output signals can be driven on either falling edge or
rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows
to reach better timing performance, and thus to increase data transfer
frequency.

There are few pre-requisites for enabling the HSPE bit
- Controller should support High-Speed-Enable Bit and
- Controller should not be using DDR Mode and
- Controller should advertise that it supports High Speed in
  capabilities register and
- MMC/SD clock coming out of controller > 25MHz

Subject: [PATCH 3164/3298] mmc: omap_hsmmc: Introduce
 omap_hsmmc_prepare/complete

prepare() is supposed to prevent new children from being registered.
On the MMC subsystem, children (new cards) registration starts with
the card detect IRQ.

Move card detect IRQ disabling to prepare() so that no new cards
will be registered while we're trying to suspend.

Likewise, move card detect IRQ enabling to complete() so we only
try to register new children after our MMC IP is back up.

Subject: [PATCH 3169/3298] mmc: host: sdhci-s3c: Use devm_gpio_request to
 request GPIOs

The set of GPIO pins used by sdhci-s3c driver varies between
configurations, such as card detect method, pinctrl availability, etc.
This overly complicates the code requesting and freeing GPIO pins, which
must check which pins are used, when freeing them.

This patch modifies the sdhci-s3c driver to use devm_gpio_request to
free requested pins automatically after unbinding the driver.

Subject: [PATCH 3174/3298] mmc: sdio: Add empty bus-level suspend/resume
 callbacks

Suspend methods provided by SDIO drivers are not supposed to be called by
the PM core.  Instead, when the SDIO core gets to suspend a device's
ancestor, it calls the device driver's suspend routine.  However, the PM
core executes suspend callback routines directly for device drivers whose
bus types don't provide suspend callbacks.  In consequece, because the
SDIO bus type doesn't provide a suspend callback, the SDIO drivers'
suspend routines will be executed by the PM core (which shouldn't
happen).

To prevent this from happening, add empty system suspend/resume callbacks
for the SDIO bus type.

An analogous change had been made already by commit (e841a7c mmc: sdio:
Use empty system suspend/resume callbacks at the bus level), but then it
was reverted inadvertently by commit (d8e2ac3 mmc: sdio: Fix PM_SLEEP
related build warnings) that attempted to fix build warnings introduced
by commit e841a7c.

Subject: [PATCH 3175/3298] mmc: sdhci: add quirk for lack of 1.8v support

The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v
capable, and it truthfully reports so in its capabilities. This
alternate voltage is used for driving new "UHS-I" SD cards at their
full speed.

However, what the controller doesn't know is that the motherboard
physically doesn't have a 1.8v supply available.

Add a quirk so that systems such as this one can override disable
1.8v support, adding support for UHS-I cards (by running them at
3.3v).

This avoids a problem where the system would first try to run the
card at 1.8v, fail, and then not be able to fully reset the card
to retry at the normal 3.3v voltage.

This is more appropriate than using the MISSING_CAPS quirk, which
is intended for cases where the SDHCI controller is actually lying
about its capabilities, and would force us to somehow override both
caps words from another source.

The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v
capable, and it truthfully reports so in its capabilities. This
alternate voltage is used for driving new "UHS-I" SD cards at their
full speed.

However, what the controller doesn't know is that the motherboard
physically doesn't have a 1.8v supply available, so attempting to
switch to the 1.8v level will result in a situation that cannot be
recovered from without physically replugging the SD card.

Add a device tree flag that can be used on systems like these,
and hook it up to the equivalent SDHCI quirk.

Subject: [PATCH 3184/3298] mmc: Limit MMC speed to 52MHz if not HS200

If "caps2" host capabilities does not indicate support for MMC
HS200, don't allow clock speeds >52MHz. Currently, for MMC, the
clock speed is set to the lesser of the max speed the eMMC module
supports (card->ext_csd.hs_max_dtr) or the max base clock of the
host controller (host->f_max based on BASE_CLK_FREQ in the host
CAPS register). This means that a host controller that doesn't
support HS200 mode but has a base clock of 100MHz and an eMMC module
that supports HS200 speeds will end up using a 100MHz clock.

Subject: [PATCH 3187/3298] mmc: eSDHC: Recover from ADMA errors

A-003500: False ADMA Error might be reported when ADMA is used for
multiple block read command with Stop at Block Gap. If PROCTL[SABGREQ]
is set when the particular block's data is received by the System side
logic before entire block (with CRC) data is received by the SD side
logic, and also if ADMA descriptor line is fetched at the same time,
then DMA engine might report false ADMA error. eSDHC might not be able
to Continue (PROCTL[CREQ]=1) after Stop at Block Gap.
This issue will impact the eSDHC IP VVN2.3.

Subject: [PATCH 3190/3298] mmc: sdhci-dove: allow GPIOs to be used for card
 detection on Dove

This commit taken from Rabeeh's Cubox kernel and re-worked for DT;
Sebastian Hasselbrath is believed to be the original author.

Some Cuboxes require a GPIO for card detection; this implements the
optional GPIO support for card detection.  This GPIO is logic 0 for
card inserted.

Subject: [PATCH 3192/3298] mm: compaction: validate pfn range passed to
 isolate_freepages_block

Commit 0bf380bc70ec ("mm: compaction: check pfn_valid when entering a
new MAX_ORDER_NR_PAGES block during isolation for migration") added a
check for pfn_valid() when isolating pages for migration as the scanner
does not necessarily start pageblock-aligned.

Since commit c89511ab2f8f ("mm: compaction: Restart compaction from near
where it left off"), the free scanner has the same problem.  This patch
makes sure that the pfn range passed to isolate_freepages_block() is
within the same block so that pfn_valid() checks are unnecessary.

In answer to Henrik's wondering why others have not reported this:
reproducing this requires a large enough hole with the right aligment to
have compaction walk into a PFN range with no memmap.  Size and
alignment depends in the memory model - 4M for FLATMEM and 128M for
SPARSEMEM on x86.  It needs a "lucky" machine.

Subject: [PATCH 3193/3298] mm: vmscan: do not keep kswapd looping forever due
 to individual uncompactable zones

When a zone meets its high watermark and is compactable in case of
higher order allocations, it contributes to the percentage of the node's
memory that is considered balanced.

This requirement, that a node be only partially balanced, came about
when kswapd was desparately trying to balance tiny zones when all bigger
zones in the node had plenty of free memory.  Arguably, the same should
apply to compaction: if a significant part of the node is balanced
enough to run compaction, do not get hung up on that tiny zone that
might never get in shape.

When the compaction logic in kswapd is reached, we know that at least
25% of the node's memory is balanced properly for compaction (see
zone_balanced and pgdat_balanced).  Remove the individual zone checks
that restart the kswapd cycle.

Otherwise, we may observe more endless looping in kswapd where the
compaction code loops back to reclaim because of a single zone and
reclaim does nothing because the node is considered balanced overall.

See for example

Subject: [PATCH 3194/3298] tmpfs: fix shared mempolicy leak

This fixes a regression in 3.7-rc, which has since gone into stable.

Commit 00442ad04a5e ("mempolicy: fix a memory corruption by refcount
imbalance in alloc_pages_vma()") changed get_vma_policy() to raise the
refcount on a shmem shared mempolicy; whereas shmem_alloc_page() went
on expecting alloc_page_vma() to drop the refcount it had acquired.
This deserves a rework: but for now fix the leak in shmem_alloc_page().

Hugh: shmem_swapin() did not need a fix, but surely it's clearer to use
the same refcounting there as in shmem_alloc_page(), delete its onstack
mempolicy, and the strange mpol_cond_copy() and __mpol_cond_copy() -
those were invented to let swapin_readahead() make an unknown number of
calls to alloc_pages_vma() with one mempolicy; but since 00442ad04a5e,
alloc_pages_vma() has kept refcount in balance, so now no problem.

Subject: [PATCH 3195/3298] gpio: pcf857x: use client->irq for gpio_to_irq()

6e20a0a429bd4dc07d6de16d9c247270e04e4aa0
(gpio: pcf857x: enable gpio_to_irq() support)
added gpio_to_irq() support on pcf857x driver,
but it used pdata->irq.
This patch modifies driver to use client->irq instead of it.
It modifies kzm9g board platform settings,
and device probe information too.
This patch is tested on kzm9g board

Subject: [PATCH 3200/3298] tcp: bug fix Fast Open client retransmission

If SYN-ACK partially acks SYN-data, the client retransmits the
remaining data by tcp_retransmit_skb(). This increments lost recovery
state variables like tp->retrans_out in Open state. If loss recovery
happens before the retransmission is acked, it triggers the WARN_ON
check in tcp_fastretrans_alert(). For example: the client sends
SYN-data, gets SYN-ACK acking only ISN, retransmits data, sends
another 4 data packets and get 3 dupacks.

Since the retransmission is not caused by network drop it should not
update the recovery state variables. Further the server may return a
smaller MSS than the cached MSS used for SYN-data, so the retranmission
needs a loop. Otherwise some data will not be retransmitted until timeout
or other loss recovery events.

Subject: [PATCH 3201/3298] net: gro: fix possible panic in skb_gro_receive()

commit 2e71a6f8084e (net: gro: selective flush of packets) added
a bug for skbs using frag_list. This part of the GRO stack is rarely
used, as it needs skb not using a page fragment for their skb->head.

Most drivers do use a page fragment, but some of them use GFP_KERNEL
allocations for the initial fill of their RX ring buffer.

napi_gro_flush() overwrite skb->prev that was used for these skb to
point to the last skb in frag_list.

Fix this using a separate field in struct napi_gro_cb to point to the
last fragment.

+ACPI based device enumeration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ACPI 5 introduced a set of new resources (UartTSerialBus, I2cSerialBus,
+SpiSerialBus, GpioIo and GpioInt) which can be used in enumerating slave
+devices behind serial bus controllers.
+
+In addition we are starting to see peripherals integrated in the
+SoC/Chipset to appear only in ACPI namespace. These are typically devices
+that are accessed through memory-mapped registers.
+
+In order to support this and re-use the existing drivers as much as
+possible we decided to do following:
+
+	o Devices that have no bus connector resource are represented as
+	  platform devices.
+
+	o Devices behind real busses where there is a connector resource
+	  are represented as struct spi_device or struct i2c_device
+	  (standard UARTs are not busses so there is no struct uart_device).
+
+As both ACPI and Device Tree represent a tree of devices (and their
+resources) this implementation follows the Device Tree way as much as
+possible.
+
+The ACPI implementation enumerates devices behind busses (platform, SPI and
+I2C), creates the physical devices and binds them to their ACPI handle in
+the ACPI namespace.
+
+This means that when ACPI_HANDLE(dev) returns non-NULL the device was
+enumerated from ACPI namespace. This handle can be used to extract other
+device-specific configuration. There is an example of this below.
+
+Platform bus support
+~~~~~~~~~~~~~~~~~~~~
+Since we are using platform devices to represent devices that are not
+connected to any physical bus we only need to implement a platform driver
+for the device and add supported ACPI IDs. If this same IP-block is used on
+some other non-ACPI platform, the driver might work out of the box or needs
+some minor changes.
+
+Adding ACPI support for an existing driver should be pretty
+straightforward. Here is the simplest example:
+
+	#ifdef CONFIG_ACPI
+	static struct acpi_device_id mydrv_acpi_match[] = {
+		/* ACPI IDs here */
+		{ }
+	};
+	MODULE_DEVICE_TABLE(acpi, mydrv_acpi_match);
+	#endif
+
+	static struct platform_driver my_driver = {
+		...
+		.driver = {
+			.acpi_match_table = ACPI_PTR(mydrv_acpi_match),
+		},
+	};
+
+If the driver needs to perform more complex initialization like getting and
+configuring GPIOs it can get its ACPI handle and extract this information
+from ACPI tables.
+
+Currently the kernel is not able to automatically determine from which ACPI
+device it should make the corresponding platform device so we need to add
+the ACPI device explicitly to acpi_platform_device_ids list defined in
+drivers/acpi/scan.c. This limitation is only for the platform devices, SPI
+and I2C devices are created automatically as described below.
+
+SPI serial bus support
+~~~~~~~~~~~~~~~~~~~~~~
+Slave devices behind SPI bus have SpiSerialBus resource attached to them.
+This is extracted automatically by the SPI core and the slave devices are
+enumerated once spi_register_master() is called by the bus driver.
+
+Here is what the ACPI namespace for a SPI slave might look like:
+
+	Device (EEP0)
+	{
+		Name (_ADR, 1)
+		Name (_CID, Package() {
+			"ATML0025",
+			"AT25",
+		})
+		...
+		Method (_CRS, 0, NotSerialized)
+		{
+			SPISerialBus(1, PolarityLow, FourWireMode, 8,
+				ControllerInitiated, 1000000, ClockPolarityLow,
+				ClockPhaseFirst, "\\_SB.PCI0.SPI1",)
+		}
+		...
+
+The SPI device drivers only need to add ACPI IDs in a similar way than with
+the platform device drivers. Below is an example where we add ACPI support
+to at25 SPI eeprom driver (this is meant for the above ACPI snippet):
+
+	#ifdef CONFIG_ACPI
+	static struct acpi_device_id at25_acpi_match[] = {
+		{ "AT25", 0 },
+		{ },
+	};
+	MODULE_DEVICE_TABLE(acpi, at25_acpi_match);
+	#endif
+
+	static struct spi_driver at25_driver = {
+		.driver = {
+			...
+			.acpi_match_table = ACPI_PTR(at25_acpi_match),
+		},
+	};
+
+Note that this driver actually needs more information like page size of the
+eeprom etc. but at the time writing this there is no standard way of
+passing those. One idea is to return this in _DSM method like:
+
+	Device (EEP0)
+	{
+		...
+		Method (_DSM, 4, NotSerialized)
+		{
+			Store (Package (6)
+			{
+				"byte-len", 1024,
+				"addr-mode", 2,
+				"page-size, 32
+			}, Local0)
+
+			// Check UUIDs etc.
+
+			Return (Local0)
+		}
+
+Then the at25 SPI driver can get this configation by calling _DSM on its
+ACPI handle like:
+
+	struct acpi_buffer output = { ACPI_ALLOCATE_BUFFER, NULL };
+	struct acpi_object_list input;
+	acpi_status status;
+
+	/* Fill in the input buffer */
+
+	status = acpi_evaluate_object(ACPI_HANDLE(&spi->dev), "_DSM",
+				      &input, &output);
+	if (ACPI_FAILURE(status))
+		/* Handle the error */
+
+	/* Extract the data here */
+
+	kfree(output.pointer);
+
+I2C serial bus support
+~~~~~~~~~~~~~~~~~~~~~~
+The slaves behind I2C bus controller only need to add the ACPI IDs like
+with the platform and SPI drivers. However the I2C bus controller driver
+needs to call acpi_i2c_register_devices() after it has added the adapter.
+
+An I2C bus (controller) driver does:
+
+	...
+	ret = i2c_add_numbered_adapter(adapter);
+	if (ret)
+		/* handle error */
+
+	of_i2c_register_devices(adapter);
+	/* Enumerate the slave devices behind this bus via ACPI */
+	acpi_i2c_register_devices(adapter);
+
+Below is an example of how to add ACPI support to the existing mpu3050
+input driver:
+
+	#ifdef CONFIG_ACPI
+	static struct acpi_device_id mpu3050_acpi_match[] = {
+		{ "MPU3050", 0 },
+		{ },
+	};
+	MODULE_DEVICE_TABLE(acpi, mpu3050_acpi_match);
+	#endif
+
+	static struct i2c_driver mpu3050_i2c_driver = {
+		.driver	= {
+			.name	= "mpu3050",
+			.owner	= THIS_MODULE,
+			.pm	= &mpu3050_pm,
+			.of_match_table = mpu3050_of_match,
+			.acpi_match_table  ACPI_PTR(mpu3050_acpi_match),
+		},
+		.probe		= mpu3050_probe,
+		.remove		= __devexit_p(mpu3050_remove),
+		.id_table	= mpu3050_ids,
+	};
+
+GPIO support
+~~~~~~~~~~~~
+ACPI 5 introduced two new resources to describe GPIO connections: GpioIo
+and GpioInt. These resources are used be used to pass GPIO numbers used by
+the device to the driver. For example:
+
+	Method (_CRS, 0, NotSerialized)
+	{
+		Name (SBUF, ResourceTemplate()
+		{
+			GpioIo (Exclusive, PullDefault, 0x0000, 0x0000,
+				IoRestrictionOutputOnly, "\\_SB.PCI0.GPI0",
+				0x00, ResourceConsumer,,)
+			{
+				// Pin List
+				0x0055
+			}
+			...
+
+			Return (SBUF)
+		}
+	}
+
+These GPIO numbers are controller relative and path "\\_SB.PCI0.GPI0"
+specifies the path to the controller. In order to use these GPIOs in Linux
+we need to translate them to the Linux GPIO numbers.
+
+The driver can do this by including <linux/acpi_gpio.h> and then calling
+acpi_get_gpio(path, gpio). This will return the Linux GPIO number or
+negative errno if there was no translation found.
+
+Other GpioIo parameters must be converted first by the driver to be
+suitable to the gpiolib before passing them.
+
+In case of GpioInt resource an additional call to gpio_to_irq() must be
+done before calling request_irq().

Subject: [PATCH 3205/3298] vfs: fix O_DIRECT read past end of block device

The direct-IO write path already had the i_size checks in mm/filemap.c,
but it turns out the read path did not, and removing the block size
checks in fs/block_dev.c (commit bbec0270bdd8: "blkdev_max_block: make
private to fs/buffer.c") removed the magic "shrink IO to past the end of
the device" code there.

Fix it by truncating the IO to the size of the block device, like the
write path already does.

NOTE! I suspect the write path would be *much* better off doing it this
way in fs/block_dev.c, rather than hidden deep in mm/filemap.c.  The
mm/filemap.c code is extremely hard to follow, and has various
conditionals on the target being a block device (ie the flag passed in
to 'generic_write_checks()', along with a conditional update of the
inode timestamp etc).

It is also quite possible that we should treat this whole block device
size as a "s_maxbytes" issue, and try to make the logic even more
generic.  However, in the meantime this is the fairly minimal targeted
fix.

Noted by Milan Broz thanks to a regression test for the cryptsetup
reencrypt tool.

Subject: [PATCH 3206/3298] mm: vmscan: fix inappropriate zone congestion
 clearing

commit c702418f8a2f ("mm: vmscan: do not keep kswapd looping forever due
to individual uncompactable zones") removed zone watermark checks from
the compaction code in kswapd but left in the zone congestion clearing,
which now happens unconditionally on higher order reclaim.

This messes up the reclaim throttling logic for zones with
dirty/writeback pages, where zones should only lose their congestion
status when their watermarks have been restored.

Remove the clearing from the zone compaction section entirely.  The
preliminary zone check and the reclaim loop in kswapd will clear it if
the zone is considered balanced.

Subject: [PATCH 3207/3298] inet_diag: fix oops for IPv4 AF_INET6 TCP SYN-RECV
 state

Fix inet_diag to be aware of the fact that AF_INET6 TCP connections
instantiated for IPv4 traffic and in the SYN-RECV state were actually
created with inet_reqsk_alloc(), instead of inet6_reqsk_alloc(). This
means that for such connections inet6_rsk(req) returns a pointer to a
random spot in memory up to roughly 64KB beyond the end of the
request_sock.

With this bug, for a server using AF_INET6 TCP sockets and serving
IPv4 traffic, an inet_diag user like `ss state SYN-RECV` would lead to
inet_diag_fill_req() causing an oops or the export to user space of 16
bytes of kernel memory as a garbage IPv6 address, depending on where
the garbage inet6_rsk(req) pointed.

Add logic to validate INET_DIAG_BC_S_COND and INET_DIAG_BC_D_COND

Previously we did not validate the inet_diag_hostcond, address family,
address length, and prefix length. So a malicious user could make the
kernel read beyond the end of the bytecode array by claiming to have a
whole inet_diag_hostcond when the bytecode was not long enough to
contain a whole inet_diag_hostcond of the given address family. Or
they could make the kernel read up to about 27 bytes beyond the end of
a connection address by passing a prefix length that exceeded the
length of addresses of the given family.

Subject: [PATCH 3209/3298] inet_diag: avoid unsafe and nonsensical prefix
 matches in inet_diag_bc_run()

Add logic to check the address family of the user-supplied conditional
and the address family of the connection entry. We now do not do
prefix matching of addresses from different address families (AF_INET
vs AF_INET6), except for the previously existing support for having an
IPv4 prefix match an IPv4-mapped IPv6 address (which this commit
maintains as-is).

This change is needed for two reasons:

(1) The addresses are different lengths, so comparing a 128-bit IPv6
prefix match condition to a 32-bit IPv4 connection address can cause
us to unwittingly walk off the end of the IPv4 address and read
garbage or oops.

(2) The IPv4 and IPv6 address spaces are semantically distinct, so a
simple bit-wise comparison of the prefixes is not meaningful, and
would lead to bogus results (except for the IPv4-mapped IPv6 case,
which this commit maintains).

 prevent unsafe reads

Add logic to verify that a port comparison byte code operation
actually has the second inet_diag_bc_op from which we read the port
for such operations.

Previously the code blindly referenced op[1] without first checking
whether a second inet_diag_bc_op struct could fit there. So a
malicious user could make the kernel read 4 bytes beyond the end of
the bytecode array by claiming to have a whole port comparison byte
code (2 inet_diag_bc_op structs) when in fact the bytecode was not
long enough to hold both.

Subject: [PATCH 3211/3298] gpio: add TS-5500 DIO blocks support

Technologic Systems TS-5500 provides digital I/O lines exposed through
pin blocks. On this platform, there are three of them, named DIO1, DIO2
and LCD port, that may be used as a DIO block.

The TS-5500 pin blocks are described in the product's wiki:
http://wiki.embeddedarm.com/wiki/TS-5500#Digital_I.2FO

This driver is not limited to the TS-5500 blocks. It can be extended to
support similar boards pin blocks, such as on the TS-5600.

This patch is the V2 of the previous https://lkml.org/lkml/2012/9/25/671
with corrections suggested by Linus Walleij.

Subject: [PATCH 3212/3298] gpio: Provide the STMPE GPIO driver with its own
 IRQ Domain

The STMPE GPIO driver can be used as an IRQ controller by some
related devices. Here we provide it with its very own IRQ Domain
so that IRQs can be issued dynamically. This will stand the
driver in good stead when it is enabled for Device Tree, as this
it a prerequisite.

Subject: [PATCH 3213/3298] x86: Fix the error of using "const" in
 gen-insn-attr-x86.awk

The original version code causes following sparse warnings:
arch/x86/lib/inat-tables.c:1080:25: warning: duplicate const
arch/x86/lib/inat-tables.c:1095:25: warning: duplicate const
arch/x86/lib/inat-tables.c:1118:25: warning: duplicate const

for the variables inat_escape_tables, inat_group_tables, and inat_avx_tables
in the code generated by gen-insn-attr-x86.awk.

The author Masami Hiramutsu says here is to make both the value pointed by the
pointers and the pointers itself read-only, so we move the "const" to be after
the "*".

Subject: [PATCH 3214/3298] Revert "mm: avoid waking kswapd for THP allocations
 when compaction is deferred or contended"

This reverts commit 782fd30406ecb9d9b082816abe0c6008fc72a7b0.

We are going to reinstate the __GFP_NO_KSWAPD flag that has been
removed, the removal reverted, and then removed again.  Making this
commit a pointless fixup for a problem that was caused by the removal of
__GFP_NO_KSWAPD flag.

The thing is, we really don't want to wake up kswapd for THP allocations
(because they fail quite commonly under any kind of memory pressure,
including when there is tons of memory free), and these patches were
just trying to fix up the underlying bug: the original removal of
__GFP_NO_KSWAPD in commit c654345924f7 ("mm: remove __GFP_NO_KSWAPD")
was simply bogus.

Subject: [PATCH 3215/3298] ipv4: ip_check_defrag must not modify skb before
 unsharing

ip_check_defrag() might be called from af_packet within the
RX path where shared SKBs are used, so it must not modify
the input SKB before it has unshared it for defragmentation.
Use skb_copy_bits() to get the IP header and only pull in
everything later.

The same is true for the other caller in macvlan as it is
called from dev->rx_handler which can also get a shared SKB.

Subject: [PATCH 3216/3298] Revert "revert "Revert "mm: remove
 __GFP_NO_KSWAPD""" and associated damage

This reverts commits a50915394f1fc02c2861d3b7ce7014788aa5066e and
d7c3b937bdf45f0b844400b7bf6fd3ed50bac604.

This is a revert of a revert of a revert.  In addition, it reverts the
even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the
original commits in linux-next.

It turns out that the original patch really was bogus, and that the
original revert was the correct thing to do after all.  We thought we
had fixed the problem, and then reverted the revert, but the problem
really is fundamental: waking up kswapd simply isn't the right thing to
do, and direct reclaim sometimes simply _is_ the right thing to do.

When certain allocations fail, we simply should try some direct reclaim,
and if that fails, fail the allocation.  That's the right thing to do
for THP allocations, which can easily fail, and the GPU allocations want
to do that too.

So starting kswapd is sometimes simply wrong, and removing the flag that
said "don't start kswapd" was a mistake.  Let's hope we never revisit
this mistake again - and certainly not this many times ;)

Subject: [PATCH 3217/3298] mmc: sdhci-acpi: enable runtime-pm for device HID
 INT33C6

sdhci-acpi supports ACPI devices which have compatibility ID
PNP0D40, however it is not possible to know if those devices
will all work correctly with runtime-pm, so that must be configured
per hardware ID.

For INT33C6, several related quirks, capabilities and flags are set:

	MMC_CAP_NONREMOVABLE
		The SDIO card will never be removable

	SDHCI_ACPI_RUNTIME_PM
		Enable runtime-pm of the host controller

	MMC_CAP_POWER_OFF_CARD
		Enable runtime-pm of the SDIO card

	MMC_PM_KEEP_POWER
		SDIO card has the capability to remain powered up
		during system suspend

	SDHCI_QUIRK2_HOST_OFF_CARD_ON
		Always do a full reset during system resume
		because the card may be already initialized having
		not been powered off.

Wake-ups from the INT33C6 host controller are not supported, so the
following capability must *not* be set:

	MMC_PM_WAKE_SDIO_IRQ
		Enable wake on card interrupt

Subject: [PATCH 3223/3298] clk: introduce optional disable_unused callback

Some gate clocks have special needs which must be handled during the
disable-unused clocks sequence.  These needs might be driven by software
due to the fact that we're disabling a clock outside of the normal
clk_disable path and a clk's enable_count will not be accurate.  On the
other hand a specific hardware programming sequence might need to be
followed for this corner case.

This change is needed for the upcoming OMAP port to the common clock
framework.  Specifically, it is undesirable to treat the disable-unused
path identically to the normal clk_disable path since other software
layers are involved.  In this case OMAP's clockdomain code throws WARNs
and bails early due to the clock's enable_count being set to zero.  A
custom callback mitigates this problem nicely.

Subject: [PATCH 3225/3298] mm: dmapool: use provided gfp flags for all
 dma_alloc_coherent() calls

dmapool always calls dma_alloc_coherent() with GFP_ATOMIC flag,
regardless the flags provided by the caller. This causes excessive
pruning of emergency memory pools without any good reason. Additionaly,
on ARM architecture any driver which is using dmapools will sooner or
later  trigger the following error:
"ERROR: 256 KiB atomic DMA coherent pool is too small!
Please increase it with coherent_pool= kernel parameter!".
Increasing the coherent pool size usually doesn't help much and only
delays such error, because all GFP_ATOMIC DMA allocations are always
served from the special, very limited memory pool.

This patch changes the dmapool code to correctly use gfp flags provided
by the dmapool caller.

Subject: [PATCH 3226/3298] drivers: cma: represent physical addresses as
 phys_addr_t

This commit changes the CMA early initialization code to use phys_addr_t
for representing physical addresses instead of unsigned long.

Without this change, among other things, dma_declare_contiguous() simply
discards any memory regions whose address is not representable as unsigned
long.

This is a problem on 32-bit PAE machines where unsigned long is 32-bit
but physical address space is larger.

Subject: [PATCH 3227/3298] Revert "sched/autogroup: Fix crash on reboot when
 autogroup is disabled"

This reverts commit 5258f386ea4e8454bc801fb443e8a4217da1947c,
because the underlying autogroups bug got fixed upstream in
a better way, via:

  fd8ef11730f1 Revert "sched, autogroup: Stop going ahead if autogroup is disabled"

Subject: [PATCH 3228/3298] writeback: remove nr_pages_dirtied arg from
 balance_dirty_pages_ratelimited_nr()

There is no reason to pass the nr_pages_dirtied argument, because
nr_pages_dirtied value from the caller is unused in
balance_dirty_pages_ratelimited_nr().

Subject: [PATCH 3229/3298] mm: show migration types in show_mem

This is useful to diagnose the reason for page allocation failure for
cases where there appear to be several free pages.

Example, with this alloc_pages(GFP_ATOMIC) failure:

 swapper/0: page allocation failure: order:0, mode:0x0
 ...
 Mem-info:
 Normal per-cpu:
 CPU    0: hi:   90, btch:  15 usd:  48
 CPU    1: hi:   90, btch:  15 usd:  21
 active_anon:0 inactive_anon:0 isolated_anon:0
  active_file:0 inactive_file:84 isolated_file:0
  unevictable:0 dirty:0 writeback:0 unstable:0
  free:4026 slab_reclaimable:75 slab_unreclaimable:484
  mapped:0 shmem:0 pagetables:0 bounce:0
 Normal free:16104kB min:2296kB low:2868kB high:3444kB active_anon:0kB
 inactive_anon:0kB active_file:0kB inactive_file:336kB unevictable:0kB
 isolated(anon):0kB isolated(file):0kB present:331776kB mlocked:0kB
 dirty:0kB writeback:0kB mapped:0kB shmem:0kB slab_reclaimable:300kB
 slab_unreclaimable:1936kB kernel_stack:328kB pagetables:0kB unstable:0kB
 bounce:0kB writeback_tmp:0kB pages_scanned:0 all_unreclaimable? no
 lowmem_reserve[]: 0 0

Before the patch, it's hard (for me, at least) to say why all these free
chunks weren't considered for allocation:

 Normal: 0*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 1*256kB 1*512kB
 1*1024kB 1*2048kB 3*4096kB = 16128kB

After the patch, it's obvious that the reason is that all of these are
in the MIGRATE_CMA (C) freelist:

 Normal: 0*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 1*256kB (C) 1*512kB
 (C) 1*1024kB (C) 1*2048kB (C) 3*4096kB (C) = 16128kB

Subject: [PATCH 3237/3298] memory hotplug: suppress "Device memoryX does not
 have a release() function" warning

When calling remove_memory_block(), the function shows following message
at device_release().

"Device 'memory528' does not have a release() function, it is broken and
must be fixed."

The reason is memory_block's device struct does not have a release()
function.

So the patch registers memory_block_release() to the device's release()
function for suppressing the warning message.  Additionally, the patch
moves kfree(mem) into the release function since the release function is
prepared as a means to free a memory_block struct.

Subject: [PATCH 3238/3298] memory-hotplug: skip HWPoisoned page when offlining
 pages

hwpoisoned may be set when we offline a page by the sysfs interface
/sys/devices/system/memory/soft_offline_page or
/sys/devices/system/memory/hard_offline_page. If we don't clear
this flag when onlining pages, this page can't be freed, and will
not in free list. So we can't offline these pages again. So we
should skip such page when offlining pages.

Subject: [PATCH 3240/3298] memory-hotplug: auto offline page_cgroup when
 onlining memory block failed

When a memory block is onlined, we will try allocate memory on that node
to store page_cgroup.  If onlining the memory block failed, we don't
offline the page cgroup, and we have no chance to offline this page cgroup
unless the memory block is onlined successfully again.  It will cause that
we can't hot-remove the memory device on that node, because some memory is
used to store page cgroup.  If onlining the memory block is failed, there
is no need to stort page cgroup for this memory.  So auto offline
page_cgroup when onlining memory block failed.

Subject: [PATCH 3241/3298] memory-hotplug: fix NR_FREE_PAGES mismatch

NR_FREE_PAGES will be wrong after offlining pages.  We add/dec
NR_FREE_PAGES like this now:

1. move all pages in buddy system to MIGRATE_ISOLATE, and dec NR_FREE_PAGES

2. don't add NR_FREE_PAGES when it is freed and the migratetype is
   MIGRATE_ISOLATE

3. dec NR_FREE_PAGES when offlining isolated pages.

4. add NR_FREE_PAGES when undoing isolate pages.

When we come to step 3, all pages are in MIGRATE_ISOLATE list, and
NR_FREE_PAGES are right.  When we come to step4, all pages are not in
buddy system, so we don't change NR_FREE_PAGES in this step, but we change
NR_FREE_PAGES in step3.  So NR_FREE_PAGES is wrong after offlining pages.
So there is no need to change NR_FREE_PAGES in step3.

This patch also fixs a problem in step2: if the migratetype is
MIGRATE_ISOLATE, we should not add NR_FRR_PAGES when we remove pages from
pcppages.

Subject: [PATCH 3243/3298] memory-hotplug: suppress "Device nodeX does not
 have a release() function" warning

When calling unregister_node(), the function shows following message at
device_release().

"Device 'node2' does not have a release() function, it is broken and must
be fixed."

The reason is node's device struct does not have a release() function.

So the patch registers node_device_release() to the device's release()
function for suppressing the warning message.  Additionally, the patch
adds memset() to initialize a node struct into register_node().  Because
the node struct is part of node_devices[] array and it cannot be freed by
node_device_release().  So if system reuses the node struct, it has a
garbage.

Subject: [PATCH 3244/3298] memory-hotplug, mm/sparse.c: clear the memory to
 store struct page

If sparse memory vmemmap is enabled, we can't free the memory to store
struct page when a memory device is hotremoved, because we may store
struct page in the memory to manage the memory which doesn't belong to
this memory device.  When we hotadded this memory device again, we will
reuse this memory to store struct page, and struct page may contain some
obsolete information, and we will get bad-page state:

Subject: [PATCH 3245/3298] memory-hotplug: allocate zone's pcp before onlining
 pages

We use __free_page() to put a page to buddy system when onlining pages.
__free_page() will store NR_FREE_PAGES in zone's pcp.vm_stat_diff, so we
should allocate zone's pcp before onlining pages, otherwise we will lose
some free pages.

Subject: [PATCH 3246/3298] memory_hotplug: fix possible incorrect
 node_states[N_NORMAL_MEMORY]

Currently memory_hotplug only manages the node_states[N_HIGH_MEMORY], it
forgets to manage node_states[N_NORMAL_MEMORY].  This may cause
node_states[N_NORMAL_MEMORY] to become incorrect.

Example, if a node is empty before online, and we online a memory which is
in ZONE_NORMAL.  And after online, node_states[N_HIGH_MEMORY] is correct,
but node_states[N_NORMAL_MEMORY] is incorrect, the online code doesn't set
the new online node to node_states[N_NORMAL_MEMORY].

The same thing will happen when offlining (the offline code doesn't clear
the node from node_states[N_NORMAL_MEMORY] when needed).  Some memory
managment code depends node_states[N_NORMAL_MEMORY], so we have to fix up
the node_states[N_NORMAL_MEMORY].

We add node_states_check_changes_online() and
node_states_check_changes_offline() to detect whether
node_states[N_HIGH_MEMORY] and node_states[N_NORMAL_MEMORY] are changed
while hotpluging.

Also add @status_change_nid_normal to struct memory_notify, thus the
memory hotplug callbacks know whether the node_states[N_NORMAL_MEMORY] are
changed.  (We can add a @flags and reuse @status_change_nid instead of
introducing @status_change_nid_normal, but it will add much more
complexity in memory hotplug callback in every subsystem.  So introducing
@status_change_nid_normal is better and it doesn't change the sematics of
@status_change_nid)

Subject: [PATCH 3247/3298] slub, hotplug: ignore unrelated node's hot-adding
 and hot-removing

SLUB only focuses on the nodes which have normal memory and it ignores the
other node's hot-adding and hot-removing.

Aka: if some memory of a node which has no onlined memory is online, but
this new memory onlined is not normal memory (for example, highmem), we
should not allocate kmem_cache_node for SLUB.

And if the last normal memory is offlined, but the node still has memory,
we should remove kmem_cache_node for that node.  (The current code delays
it when all of the memory is offlined)

So we only do something when marg->status_change_nid_normal > 0.
marg->status_change_nid is not suitable here.

The same problem doesn't exist in SLAB, because SLAB allocates kmem_list3
for every node even the node don't have normal memory, SLAB tolerates
kmem_list3 on alien nodes.  SLUB only focuses on the nodes which have
normal memory, it don't tolerate alien kmem_cache_node.  The patch makes
SLUB become self-compatible and avoids WARNs and BUGs in rare conditions.

Subject: [PATCH 3248/3298] mm/memory_hotplug.c: update start_pfn in zone and
 pg_data when spanned_pages == 0.

If we hot-remove memory only and leave the cpus alive, the corresponding
node will not be removed.  But the node_start_pfn and node_spanned_pages
in pg_data will be reset to 0.  In this case, when we hot-add the memory
back next time, the node_start_pfn will always be 0 because no pfn is less
than 0.  After that, if we hot-remove the memory again, it will cause
kernel panic in function find_biggest_section_pfn() when it tries to scan
all the pfns.

The zone will also have the same problem.

This patch sets start_pfn to the start_pfn of the section being added when
spanned_pages of the zone or pg_data is 0.

  ---How to reproduce---

1. hot-add a container with some memory and cpus;
2. hot-remove the container's memory, and leave cpus there;
3. hot-add these memory again;
4. hot-remove them again;

then, the kernel will panic.

Subject: [PATCH 3250/3298] mm,vmscan: only evict file pages when we have
 plenty

If we have more inactive file pages than active file pages, we skip
scanning the active file pages altogether, with the idea that we do not
want to evict the working set when there is plenty of streaming IO in the
cache.

However, the code forgot to also skip scanning anonymous pages in that
situation.  That leads to the curious situation of keeping the active file
pages protected from being paged out when there are lots of inactive file
pages, while still scanning and evicting anonymous pages.

This patch fixes that situation, by only evicting file pages when we have
plenty of them and most are inactive.

Subject: [PATCH 3251/3298] mm: refactor reinsert of swap_info in sys_swapoff()

The block within sys_swapoff() which re-inserts the swap_info into the
swap_list in case of failure of try_to_unuse() reads a few values outside
the swap_lock.  While this is safe at that point, it is subtle code.

Simplify the code by moving the reading of these values to a separate
function, refactoring it a bit so they are read from within the swap_lock.
 This is easier to understand, and matches better the way it worked before
I unified the insertion of the swap_info from both sys_swapon and
sys_swapoff.

This change should make no functional difference.  The only real change is
moving the read of two or three structure fields to within the lock
(frontswap_map_get() is nothing more than a read of p->frontswap_map).

Subject: [PATCH 3252/3298] mm: do not call frontswap_init() during swapoff

The call to frontswap_init() was added within enable_swap_info(), which
was called not only during sys_swapon, but also to reinsert the swap_info
into the swap_list in case of failure of try_to_unuse() within
sys_swapoff.  This means that frontswap_init() might be called more than
once for the same swap area.

While as far as I could see no frontswap implementation has any problem
with it (and in fact, all the ones I found ignore the parameter passed to
frontswap_init), this could change in the future.

To prevent future problems, move the call to frontswap_init() to outside
the code shared between sys_swapon and sys_swapoff.

Subject: [PATCH 3257/3298] mm: thp: set the accessed flag for old pages on
 access fault

On x86 memory accesses to pages without the ACCESSED flag set result in
the ACCESSED flag being set automatically.  With the ARM architecture a
page access fault is raised instead (and it will continue to be raised
until the ACCESSED flag is set for the appropriate PTE/PMD).

For normal memory pages, handle_pte_fault will call pte_mkyoung
(effectively setting the ACCESSED flag).  For transparent huge pages,
pmd_mkyoung will only be called for a write fault.

This patch ensures that faults on transparent hugepages which do not
result in a CoW update the access flags for the faulting pmd.

Subject: [PATCH 3259/3298] mm, oom: allow exiting threads to have access to
 memory reserves

Exiting threads, those with PF_EXITING set, can pagefault and require
memory before they can make forward progress.  This happens, for instance,
when a process must fault task->robust_list, a userspace structure, before
detaching its memory.

These threads also aren't guaranteed to get access to memory reserves
unless oom killed or killed from userspace.  The oom killer won't grant
memory reserves if other threads are also exiting other than current and
stalling at the same point.  This prevents needlessly killing processes
when others are already exiting.

Instead of special casing all the possible situations between PF_EXITING
getting set and a thread detaching its mm where it may allocate memory,
which probably wouldn't get updated when a change is made to the exit
path, the solution is to give all exiting threads access to memory
reserves if they call the oom killer.  This allows them to quickly
allocate, detach its mm, and free the memory it represents.

Summary of Luigi's bug report:

: He had an oom condition where threads were faulting on task->robust_list
: and repeatedly called the oom killer but it would defer killing a thread
: because it saw other PF_EXITING threads.  This can happen anytime we need
: to allocate memory after setting PF_EXITING and before detaching our mm;
: if there are other threads in the same state then the oom killer won't do
: anything unless one of them happens to be killed from userspace.
:
: So instead of only deferring for PF_EXITING and !task->robust_list, it's
: better to just give them access to memory reserves to prevent a potential
: livelock so that any other faults that may be introduced in the future in
: the exit path don't cause the same problem (and hopefully we don't allow
: too many of those!).

Subject: [PATCH 3261/3298] mm: hwpoison: fix action_result() to print out
 dirty/clean

action_result() fails to print out "dirty" even if an error occurred on
a dirty pagecache, because when we check PageDirty in action_result() it
was cleared after page isolation even if it's dirty before error
handling.  This can break some applications that monitor this message,
so should be fixed.

There are several callers of action_result() except page_action(), but
either of them are not for LRU pages but for free pages or kernel pages,
so we don't have to consider dirty or not for them.

Note that PG_dirty can be set outside page locks as described in commit
6746aff74da2 ("HWPOISON: shmem: call set_page_dirty() with locked
page"), so this patch does not completely closes the race window, but
just narrows it.

Subject: [PATCH 3262/3298] mm: support more pagesizes for
 MAP_HUGETLB/SHM_HUGETLB

There was some desire in large applications using MAP_HUGETLB or
SHM_HUGETLB to use 1GB huge pages on some mappings, and stay with 2MB on
others.  This is useful together with NUMA policy: use 2MB interleaving
on some mappings, but 1GB on local mappings.

This patch extends the IPC/SHM syscall interfaces slightly to allow
specifying the page size.

It borrows some upper bits in the existing flag arguments and allows
encoding the log of the desired page size in addition to the *_HUGETLB
flag.  When 0 is specified the default size is used, this makes the
change fully compatible.

Extending the internal hugetlb code to handle this is straight forward.
Instead of a single mount it just keeps an array of them and selects the
right mount based on the specified page size.  When no page size is
specified it uses the mount of the default page size.

The change is not visible in /proc/mounts because internal mounts don't
appear there.  It also has very little overhead: the additional mounts
just consume a super block, but not more memory when not used.

I also exported the new flags to the user headers (they were previously
under __KERNEL__).  Right now only symbols for x86 and some other
architecture for 1GB and 2MB are defined.  The interface should already
work for all other architectures though.  Only architectures that define
multiple hugetlb sizes actually need it (that is currently x86, tile,
powerpc).  However tile and powerpc have user configurable hugetlb
sizes, so it's not easy to add defines.  A program on those
architectures would need to query sysfs and use the appropiate log2.

From: Andi Kleen <ak@linux.intel.com>

Subject: [PATCH 3263/3298] selftests: add a test program for variable huge
 page sizes in mmap/shmget

Also remove -Wextra because gcc-4.6 emits lots of irritating
signed/unsigned comparison warnings.

Subject: [PATCH 3264/3298] mm: augment vma rbtree with rb_subtree_gap

Define vma->rb_subtree_gap as the largest gap between any vma in the
subtree rooted at that vma, and their predecessor.  Or, for a recursive
definition, vma->rb_subtree_gap is the max of:

 - vma->vm_start - vma->vm_prev->vm_end
 - rb_subtree_gap fields of the vmas pointed by vma->rb.rb_left and
   vma->rb.rb_right

This will allow get_unmapped_area_* to find a free area of the right
size in O(log(N)) time, instead of potentially having to do a linear
walk across all the VMAs.

Also define mm->highest_vm_end as the vm_end field of the highest vma,
so that we can easily check if the following gap is suitable.

This does have the potential to make unmapping VMAs more expensive,
especially for processes with very large numbers of VMAs, where the VMA
rbtree can grow quite deep.

Subject: [PATCH 3266/3298] mm: rearrange vm_area_struct for fewer cache misses

The kernel walks the VMA rbtree in various places, including the page
fault path.  However, the vm_rb node spanned two cache lines, on 64 bit
systems with 64 byte cache lines (most x86 systems).

Rearrange vm_area_struct a little, so all the information we need to do a
VMA tree walk is in the first cache line.

Subject: [PATCH 3267/3298] mm: vm_unmapped_area() lookup function

Implement vm_unmapped_area() using the rb_subtree_gap and highest_vm_end
information to look up for suitable virtual address space gaps.

struct vm_unmapped_area_info is used to define the desired allocation
request:
 - lowest or highest possible address matching the remaining constraints
 - desired gap length
 - low/high address limits that the gap must fit into
 - alignment mask and offset

Also update the generic arch_get_unmapped_area[_topdown] functions to make
use of vm_unmapped_area() instead of implementing a brute force search.

Subject: [PATCH 3269/3298] mm: fix cache coloring on x86_64 architecture

Fix the x86-64 cache alignment code to take pgoff into account.  Use the
x86 and MIPS cache alignment code as the basis for a generic cache
alignment function.

The old x86 code will always align the mmap to aliasing boundaries,
even if the program mmaps the file with a non-zero pgoff.

If program A mmaps the file with pgoff 0, and program B mmaps the file
with pgoff 1.  The old code would align the mmaps, resulting in misaligned
pages:

  A:  0123
  B:  123

After this patch, they are aligned so the pages line up:

  A: 0123
  B:  123

Proposed by Rik van Riel.

Subject: [PATCH 3280/3298] mm: adjust address_space_operations.migratepage()
 return code

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a
guest, thus imposing performance penalties associated with the reduced
number of transparent huge pages that could be used by the guest workload.

This patch-set follows the main idea discussed at 2012 LSFMMS session:
"Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/
to introduce the required changes to the virtio_balloon driver, as well as
the changes to the core compaction & migration bits, in order to make
those subsystems aware of ballooned pages and allow memory balloon pages
become movable within a guest, thus avoiding the aforementioned
fragmentation issue

Following are numbers that prove this patch benefits on allowing
compaction to be more effective at memory ballooned guests.

Results for STRESS-HIGHALLOC benchmark, from Mel Gorman's mmtests suite,
running on a 4gB RAM KVM guest which was ballooning 512mB RAM in 64mB
chunks, at every minute (inflating/deflating), while test was running:

Subject: [PATCH 3281/3298] mm: redefine address_space.assoc_mapping

Overhaul struct address_space.assoc_mapping renaming it to
address_space.private_data and its type is redefined to void*.  By this
approach we consistently name the .private_* elements from struct
address_space as well as allow extended usage for address_space
association with other data structures through ->private_data.

Also, all users of old ->assoc_mapping element are converted to reflect
its new name and type change (->private_data).

Subject: [PATCH 3282/3298] mm: introduce a common interface for balloon pages
 mobility

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces a common interface to help a balloon driver on
making its page set movable to compaction, and thus allowing the system
to better leverage the compation efforts on memory defragmentation.

+ * Common interface definitions for making balloon pages movable by compaction.
+ *
+ * Despite being perfectly possible to perform ballooned pages migration, they
+ * make a special corner case to compaction scans because balloon pages are not
+ * enlisted at any LRU list like the other pages we do compact / migrate.
+ *
+ * As the page isolation scanning step a compaction thread does is a lockless
+ * procedure (from a page standpoint), it might bring some racy situations while
+ * performing balloon page compaction. In order to sort out these racy scenarios
+ * and safely perform balloon's page compaction and migration we must, always,
+ * ensure following these three simple rules:
+ *
+ *   i. when updating a balloon's page ->mapping element, strictly do it under
+ *      the following lock order, independently of the far superior
+ *      locking scheme (lru_lock, balloon_lock):
+ *	    +-page_lock(page);
+ *	      +--spin_lock_irq(&b_dev_info->pages_lock);
+ *	            ... page->mapping updates here ...
+ *
+ *  ii. before isolating or dequeueing a balloon page from the balloon device
+ *      pages list, the page reference counter must be raised by one and the
+ *      extra refcount must be dropped when the page is enqueued back into
+ *      the balloon device page list, thus a balloon page keeps its reference
+ *      counter raised only while it is under our special handling;
+ *
+ * iii. after the lockless scan step have selected a potential balloon page for
+ *      isolation, re-test the page->mapping flags and the page ref counter
+ *      under the proper page lock, to ensure isolating a valid balloon page
+ *      (not yet isolated, nor under release procedure)
+ *
+ * The functions provided by this interface are placed to help on coping with
+ * the aforementioned balloon page corner case, as well as to ensure the simple
+ * set of exposed rules are satisfied while we are dealing with balloon pages
+ * compaction / migration.

Subject: [PATCH 3283/3298] mm: introduce compaction and migration for
 ballooned pages

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

This patch introduces the helper functions as well as the necessary changes
to teach compaction and migration bits how to cope with pages which are
part of a guest memory balloon, in order to make them movable by memory
compaction procedures.

Subject: [PATCH 3284/3298] virtio_balloon: introduce migration primitives to
 balloon pages

Memory fragmentation introduced by ballooning might reduce significantly
the number of 2MB contiguous memory blocks that can be used within a guest,
thus imposing performance penalties associated with the reduced number of
transparent huge pages that could be used by the guest workload.

Besides making balloon pages movable at allocation time and introducing
the necessary primitives to perform balloon page migration/compaction,
this patch also introduces the following locking scheme, in order to
enhance the syncronization methods for accessing elements of struct
virtio_balloon, thus providing protection against concurrent access
introduced by parallel memory migration threads.

 - balloon_lock (mutex) : synchronizes the access demand to elements of
                          struct virtio_balloon and its queue operations;

Subject: [PATCH 3285/3298] mm: introduce putback_movable_pages()

The PATCH "mm: introduce compaction and migration for virtio ballooned pages"
hacks around putback_lru_pages() in order to allow ballooned pages to be
re-inserted on balloon page list as if a ballooned page was like a LRU page.

As ballooned pages are not legitimate LRU pages, this patch introduces
putback_movable_pages() to properly cope with cases where the isolated
pageset contains ballooned pages and LRU pages, thus fixing the mentioned
inelegant hack around putback_lru_pages().

Subject: [PATCH 3288/3298] mm: cleanup register_node()

register_node() is defined as extern in include/linux/node.h.  But the
function is only called from register_one_node() in driver/base/node.c.

So the patch defines register_node() as static.

Subject: [PATCH 3289/3298] mm, oom: change type of oom_score_adj to short

The maximum oom_score_adj is 1000 and the minimum oom_score_adj is -1000,
so this range can be represented by the signed short type with no
functional change.  The extra space this frees up in struct signal_struct
will be used for per-thread oom kill flags in the next patch.

Subject: [PATCH 3290/3298] mm, oom: fix race when specifying a thread as the
 oom origin

test_set_oom_score_adj() and compare_swap_oom_score_adj() are used to
specify that current should be killed first if an oom condition occurs in
between the two calls.

The usage is

	short oom_score_adj = test_set_oom_score_adj(OOM_SCORE_ADJ_MAX);
	...
	compare_swap_oom_score_adj(OOM_SCORE_ADJ_MAX, oom_score_adj);

to store the thread's oom_score_adj, temporarily change it to the maximum
score possible, and then restore the old value if it is still the same.

This happens to still be racy, however, if the user writes
OOM_SCORE_ADJ_MAX to /proc/pid/oom_score_adj in between the two calls.
The compare_swap_oom_score_adj() will then incorrectly reset the old value
prior to the write of OOM_SCORE_ADJ_MAX.

To fix this, introduce a new oom_flags_t member in struct signal_struct
that will be used for per-thread oom killer flags.  KSM and swapoff can
now use a bit in this member to specify that threads should be killed
first in oom conditions without playing around with oom_score_adj.

This also allows the correct oom_score_adj to always be shown when reading
/proc/pid/oom_score.

Subject: [PATCH 3291/3298] mm: cma: skip watermarks check for already isolated
 blocks in split_free_page()

Since commit 2139cbe627b8 ("cma: fix counting of isolated pages") free
pages in isolated pageblocks are not accounted to NR_FREE_PAGES counters,
so watermarks check is not required if one operates on a free page in
isolated pageblock.

Subject: [PATCH 3292/3298] mm: cma: remove watermark hacks

Commits 2139cbe627b8 ("cma: fix counting of isolated pages") and
d95ea5d18e69 ("cma: fix watermark checking") introduced a reliable
method of free page accounting when memory is being allocated from CMA
regions, so the workaround introduced earlier by commit 49f223a9cd96
("mm: trigger page reclaim in alloc_contig_range() to stabilise
watermarks") can be finally removed.

Subject: [PATCH 3294/3298] bootmem: fix wrong call parameter for
 free_bootmem()

It is strange that alloc_bootmem() returns a virtual address and
free_bootmem() requires a physical address.  Anyway, free_bootmem()'s
first parameter should be physical address.

There are some call sites for free_bootmem() with virtual address.  So fix
them.

Subject: [PATCH 3296/3298] mm, memory-hotplug: dynamic configure movable
 memory and portion memory

Add online_movable and online_kernel for logic memory hotplug.  This is
the dynamic version of "movablecore" & "kernelcore".

We have the same reason to introduce it as to introduce "movablecore" &
"kernelcore".  It has the same motive as "movablecore" & "kernelcore", but
it is dynamic/running-time:

o We can configure memory as kernelcore or movablecore after boot.

  Userspace workload is increased, we need more hugepage, we can't use
  "online_movable" to add memory and allow the system use more
  THP(transparent-huge-page), vice-verse when kernel workload is increase.

  Also help for virtualization to dynamic configure host/guest's memory,
  to save/(reduce waste) memory.

  Memory capacity on Demand

o When a new node is physically online after boot, we need to use
  "online_movable" or "online_kernel" to configure/portion it as we
  expected when we logic-online it.

  This configuration also helps for physically-memory-migrate.

o all benefit as the same as existed "movablecore" & "kernelcore".

o Preparing for movable-node, which is very important for power-saving,
  hardware partitioning and high-available-system(hardware fault
  management).

(Note, we don't introduce movable-node here.)

Action behavior:
When a memoryblock/memorysection is onlined by "online_movable", the kernel
will not have directly reference to the page of the memoryblock,
thus we can remove that memory any time when needed.

When it is online by "online_kernel", the kernel can use it.
When it is online by "online", the zone type doesn't changed.

Current constraints:
Only the memoryblock which is adjacent to the ZONE_MOVABLE
can be online from ZONE_NORMAL to ZONE_MOVABLE.

Subject: [PATCH 3298/3298] memory_hotplug: ensure every online node has NORMAL
 memory

Old memory hotplug code and new online/movable may cause a online node
don't have any normal memory, but memory-management acts bad when we have
nodes which is online but don't have any normal memory.  Example: it may
cause a bound task fail on all kernel allocation and cause the task can't
create task or create other kernel object.

So we disable non-normal-memory-node here, we will enable it when we
prepared.
