Lubomir Rintel d4b5c782b9 dt/bindings: Add binding for the BCM2835 mailbox driver
This patch was split out of Lubomir's original mailbox patch by Eric
Anholt, and the required properties documentation and examples have
been filled out more completely and updated for the driver being
changed to expose a single channel.

Dave Hansen 8c3641e957 x86/mpx: Introduce a boot-time disable flag
MPX has the _potential_ to cause some issues.  Say part of your
init system tried to protect one of its components from buffer
overflows with MPX.  If there were a false positive, it's
possible that MPX could keep a system from booting.

MPX could also potentially cause performance issues since it is
present in hot paths like the unmap path.

Allow it to be disabled at boot time.

Jonathan Corbet 8d13be5338 Merge branch 'core/documentation' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into docs-next
A week late but I managed to complete it all and moved it into Git, for better
structure and easy pulling.

Changes relative to the last submission:

  - Added higher level subsystem directories to collect features by
    subsystem:

      triton:~/tip> ls Documentation/features/
      arch-support.txt  core  debug  io  lib  list-arch.sh  locking  perf  sched  seccomp  time  vm

    each subsystem directory contains the feature directories. For example locking
    has:

      triton:~/tip> ls Documentation/features/locking/
      cmpxchg-local  lockdep  queued-rwlocks  queued-spinlocks  rwsem-optimized

    It's all pretty straightforward to navigate. Advantages are better
    visualization, plus git log is able to list changes per subsystem.

  - Prettified the visualization some more.

  - Improved/corrected the support matrices based on feedback to earlier submissions.

  - Updated the support matrices to today's linux-next, so that by the time this
    shows up in upstream in the next merge window it's really recent.
    Most notably there's a new architecture in linux-next (h8300).

This structure should address all feedback that I got and should minimize the
maintenance overhead (chance of conflicts).

Krzysztof Kozlowski a28ab162bd Documentation: ARM: EXYNOS: Describe boot loaders interface
Various boot loaders for Exynos based boards use certain memory
addresses during booting for different purposes. Mostly this is one of
following :
1. as a CPU boot address,
2. for storing magic cookie related to low power mode (AFTR, sleep).

The document, based solely on kernel source code, tries to group the
information scattered over different files. This would help in the
future when adding support for new SoC or when extending features
related to low power modes.

Mark A. Greer ab714817d7 NFC: trf7970a: Handle extra byte in response to Type 5 RMB commands
The current versions of the trf7970a has an erratum where it returns
an extra byte in the response to 'Read Multiple Block' (RMB) commands.
This command is issued to Type 5 tags (i.e., ISO/IEC 15693 tags) by
the neard daemon.

To handle this, define a new Device Tree property,
't5t-rmb-extra-byte-quirk', which indicates that the associated
trf7970a device has this erratum.  The trf7970a device driver
will then ensure that the response length to RMB commands is
reduced by one byte (for devices with the erratum).

The big thing this release has been Liam's addition of topology support

 continuation of Lars' refactoring for component support.
 
  - Support for loading ASoC topology maps from firmware, intended to be
    used to allow self-describing DSP firmware images to be built which
    can map controls added by the DSP to userspace without the kernel
    needing to know about individual DSP firmwares.
  - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring.
  - Big refactoring and cleanup serieses for the Wolfson ADSP and TI
    TAS2552 drivers.
  - Support for TI TAS571x power amplifiers.
  - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
  - Support for x86 systems with RT5650 and Qualcomm Storm.

atlas7 DMAv1 is basically moved from marco, which has never been

atlas7 DMAv2 supports chain DMA by a chain table, this
patch also adds chain DMA support for atlas7.

atlas7 DMAv1 and DMAv2 co-exist in the same chip. there are some HW
configuration differences(register offset etc.) with old prima2 chips,
so we use compatible string to differentiate old prima2 and new atlas7,
then results in different set in HW for them.

that, the modes normal and high-speed are selectable as well.

Use the new device tree property which specifies the maximum ADC
conversion clock frequencies. Depending on the mode used, the
available resulting conversion frequency are calculated
dynamically.

Duc Dang dcd19de367 PCI: xgene: Add APM X-Gene v1 PCIe MSI/MSIX termination driver
APM X-Gene v1 SoC supports its own implementation of MSI, which is not
compliant to GIC V2M specification for MSI Termination.

There is a single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports.
This MSI block supports 2048 MSI termination ports coalesced into 16
physical HW IRQ lines and shared across all 5 PCIe ports.

As there are only 16 HW IRQs to serve 2048 MSI vectors, to support
set_affinity correctly for each MSI vectors, the 16 HW IRQs are statically
allocated to 8 X-Gene v1 cores (2 HW IRQs for each cores).  To steer MSI
interrupt to target CPU, MSI vector is moved around these HW IRQs lines.
With this approach, the total MSI vectors this driver supports is reduced
to 256.

Krzysztof Kozlowski 29e5eea06b ARM: EXYNOS: Get current parent clock for power domain on/off
Using a fixed (by DTS) parent for clocks when turning on the power
domain may introduce issues in other drivers. For example when such
driver changes the parent during runtime and expects that he is the
only place of such change.

Do not rely on DTS providing the fixed parent for such clocks. Instead
before switching domain off, grab a current parent of a clock with
clk_get_parent().

trick to find the right memslot in gfn_to_rmap, retrieving the address

The comment on top of union kvm_mmu_page_role has been stale forever,
so remove it.  Speaking of stale code, remove pad_for_nice_hex_output
too: it was splitting the "access" bitfield across two bytes and thus
had effectively turned into pad_for_ugly_hex_output.

Luis R. Rodriguez 582ed8d51e Documentation: extend use case for EXPORT_SYMBOL_GPL()
Current documentation over use case for EXPORT_SYMBOL_GPL()
only acknowledges functions which are "an internal implementation
issue, and not really an interface". In practice these days
though we have some maintainers taking on preferences to require
all new functionality go in with EXPORT_SYMBOL_GPL().

A maintainer asking developers to use EXPORT_SYMBOL_GPL()
for new functionality tends to be a well accepted and understood
position that maintainers can take and typically requires the
maintainers educating contributing developers on their own
positions and requirements.

Developers who submit code to maintainers not familiar with
these preferences as optional for new functionality need explicit
guidence though as existing documentation does not acknowledge
this as a valid possibility. Without this being documented some
maintainers are reluctant to accept new functionality with
EXPORT_SYMBOL_GPL().

This extends the use case documentation for EXPORT_SYMBOL_GPL()
to acknowledge acceptance for new functionality.

One more round of drm-misc, again mostly atomic. Big thing is the
userspace blob code from Daniel Stone, with support for the mode_id blob
now added to the atomic ioctl. Finally we can do atomic modesets!

Note that the atomic ioctl is still behind the module knob since the
weston patches aren't quite ready yet imo - they lack TEST_ONLY support,
which is a fairly crucial bit of the atomic api. But besides that I think
it's all good to go. That's also why we didn't bother to hide the new blob
ioctls behind the knob, that part won't need to change. And if weston
patches get in shape in time we could throw the "atomic by default patch"
on top for 4.2.

Mike Looijmans 19fbbbbcd3 Add TI CDCE925 I2C controlled clock synthesizer driver
This driver supports the TI CDCE925 programmable clock synthesizer.
The chip contains two PLLs with spread-spectrum clocking support and
five output dividers. The driver only supports the following setup,
and uses a fixed setting for the output muxes:
  Y1 is derived from the input clock
  Y2 and Y3 derive from PLL1
  Y4 and Y5 derive from PLL2
Given a target output frequency, the driver will set the PLL and
divider to best approximate the desired output.

Ingo Molnar 669f6f96c6 Documentation/features: Explain kernel feature descriptions and add visualization script
The previous patches added arch support matrices for more than 40 generic kernel features
that need per architecture support.

The structure of the feature descriptions is the following:

Each feature has its own directory under Documentation/features/subsystem_name/feature_name/,
and the arch-support.txt file shows its current arch porting status.

For example, lockdep support is shown the following way:

    triton:~/tip> cat Documentation/features/locking/lockdep/arch-support.txt
    #
    # Feature name:          lockdep
    #         Kconfig:       LOCKDEP_SUPPORT
    #         description:   arch supports the runtime locking correctness debug facility
    #

        |         x86: |  ok  |
        |      xtensa: |  ok  |
        -----------------------

For generic kernel features that need architecture support, the
arch-support.txt file in each feature directory shows the arch
support matrix, for all upstream Linux architectures.

The meaning of entries in the tables is:

    | ok |  # feature supported by the architecture
    |TODO|  # feature not yet supported by the architecture
    | .. |  # feature cannot be supported by the hardware

This directory structure can be used in the future to add other
files - such as porting guides, testing description, etc.

The Documentation/features/ hierarchy may also include generic
kernel features that works on every architecture, in that case
the arch-support.txt file will list every architecture as
supported.

To list an architecture's unsupported features, just do something
like:

  triton:~/tip>  git grep -lE 'x86.*TODO' Documentation/features/*/*/arch-support.txt
  Documentation/features/lib/strncasecmp/arch-support.txt
  Documentation/features/time/arch-tick-broadcast/arch-support.txt

which will print the list of not yet supported features.

The Documentation/features/list-arch.sh script will print the current
support matrix of one architecture:

  triton:~/tip> Documentation/features/list-arch.sh

Greg Kroah-Hartman 00465f4c84 Update extcon for v4.2
This patchset include the huge update of extcon core and add the new one extcon
 driver and fix minor isseu of extcon drivers.
 
 Detailed description for patchset:
 1. Update the extcon core.
 - Modify the extcon device name on sysfs from device name name to 'extcon[X]'
 as following because if same extcon device are included in H/W development board,
 the one of the two device driver might be failed on the probe().
 : /sys/class/extcon/[device name] -> /sys/class/extcon/extcon[X]
 
 - Use the unique id for external connectors instead of legacy string name.
 Previously, extcon used the string name to identify the type of external
 connectors. This way have the many potential issues. So, extcon core define the
 unique id for each external connectors as following:
 
 	enum extcon {
 		EXTCON_NONE             = 0x0,
 
 		/* USB external connector */
 		EXTCON_USB              = 0x1,
 		EXTCON_USB_HOST		= 0x2,
 
 		/* Charger external connector */
 		EXTCON_TA		= 0x10,
 		EXTCON_FAST_CHARGER	= 0x11,
 		EXTCON_SLOW_CHARGER	= 0x12,
 		EXTCON_CHARGE_DOWNSTREAM = 0x13,
 
 		/* Audio and video external connector */
 		EXTCON_LINE_IN		= 0x20,
 		EXTCON_LINE_OUT		= 0x21,
 		EXTCON_MICROPHONE	= 0x22,
 		EXTCON_HEADPHONE	= 0x23,
 		...
 	};
 
 - Update tye prototype of extcon_register_notifier() by using the unique id
 (enum extcon) of external connectors.
 
 - Add extcon_get_edev_name() API to get the name of extcon device on extcon
 client driver because the name is included in 'struct extcon_dev' and 'struct
 extcon_dev' should be handled in only drivers/extcon directory. So. if extcon
 client need the name of extcon device, they could use this function.
 
 - Unify the jig/dock and MHL-TA cable name on extcon driver.
 : JIG-{USB-ON|USB-OFF|UART-ON|UART-OFF} -> JIG
 : Dock-{Smart|Desk|Audio|Card} -> DOCK
 : MHL-TA -> TA
 
 - Use the capital letter for the name of all external connectors.
 - Remove the optional print_name() function pointer from struct extcon_dev to
 maintain the consistent name of extcon device.
 
 2. Add the new extcon-axp288.c extcon driver.
 - The extcon-axp288.c driver support for AXP288 PMIC which has the BC1.2
 charger detection capability. So this extcon driver can detect the
 EXTCON_SLOW_CHARGER, EXTCON_CHARGE_DOWNSTREAM and EXTCON_FAST_CHARGER.
 
 3. Update the extcon-arizona.c driver.
 - Add support for selective detection mode when headphone detection.
 - Apply HP clamps for WM8280
 
 4. Clean-up the extcon core and drivers.
 - Add manufactor information of each extcon device.
 - Fix checkpatch warning and minor coding style on extcon.c.c
 - Fix build break if GPIOLIB is not enabled on extcon-usb-gpiio.c.
 - Set the direction of gpio when calling devm_gpiod_get() on extcon-usb-gpio.c

if the device tree does not have cell-index in the portal nodes.

No patch has yet been merged adding device tree nodes for this binding
(except a dtsi that has not yet been referenced), nor has any driver
yet been merged making use of the binding, so it's not too late to
change the binding in order to keep compatibility with existing
U-Boots.

Rafal Krypa c0d77c8844 Smack: allow multiple labels in onlycap
Smack onlycap allows limiting of CAP_MAC_ADMIN and CAP_MAC_OVERRIDE to
processes running with the configured label. But having single privileged
label is not enough in some real use cases. On a complex system like Tizen,
there maybe few programs that need to configure Smack policy in run-time
and running them all with a single label is not always practical.
This patch extends onlycap feature for multiple labels. They are configured
in the same smackfs "onlycap" interface, separated by spaces.

Arnd Bergmann 451bb7fbcc EDAC, xgene: Fix cpuid abuse
The new x-gene EDAC driver incorrectly tried to figure out the version
of one of its IP blocks by looking at the version of the CPU core, which
is only vagely related.

This removes the incorrect code and instead uses the version of the IP
block in the compatible string where it belongs.

Found using build testing on x86, which does not provide the arm64
cpuid interface.

Ard Biesheuvel 61bd93ce80 arm64: use fixmap region for permanent FDT mapping
Currently, the FDT blob needs to be in the same 512 MB region as
the kernel, so that it can be mapped into the kernel virtual memory
space very early on using a minimal set of statically allocated
translation tables.

Now that we have early fixmap support, we can relax this restriction,
by moving the permanent FDT mapping to the fixmap region instead.
This way, the FDT blob may be anywhere in memory.

This also moves the vetting of the FDT to mmu.c, since the early
init code in head.S does not handle mapping of the FDT anymore.
At the same time, fix up some comments in head.S that have gone stale.

Seymour, Shane M 05545c92db st: implement tape statistics
This patch implements tape statistics in the st module via
sysfs. Current no statistics are available for tape I/O and there
is no easy way to reuse the block layer statistics for tape
as tape is a character device and does not have perform I/O in
sector sized chunks (the size of the data written to tape
can change). For tapes we also need extra stats related to
things like tape movement (via other I/O).

There have been multiple end users requesting statistics
including AT&T (and some HP customers who have not given
permission to be named). It is impossible for them
to investigate any issues related to tape performance
in a non-invasive way.

Greg Thelen c4843a7593 memcg: add per cgroup dirty page accounting
When modifying PG_Dirty on cached file pages, update the new
MEM_CGROUP_STAT_DIRTY counter.  This is done in the same places where
global NR_FILE_DIRTY is managed.  The new memcg stat is visible in the
per memcg memory.stat cgroupfs file.  The most recent past attempt at
this was http://thread.gmane.org/gmane.linux.kernel.cgroups/8632

The new accounting supports future efforts to add per cgroup dirty
page throttling and writeback.  It also helps an administrator break
down a container's memory usage and provides evidence to understand
memcg oom kills (the new dirty count is included in memcg oom kill
messages).

The ability to move page accounting between memcg
(memory.move_charge_at_immigrate) makes this accounting more
complicated than the global counter.  The existing
mem_cgroup_{begin,end}_page_stat() lock is used to serialize move
accounting with stat updates.
Typical update operation:
	memcg = mem_cgroup_begin_page_stat(page)
	if (TestSetPageDirty()) {
		[...]
		mem_cgroup_update_page_stat(memcg)
	}
	mem_cgroup_end_page_stat(memcg)

Summary of mem_cgroup_end_page_stat() overhead:
- Without CONFIG_MEMCG it's a no-op
- With CONFIG_MEMCG and no inter memcg task movement, it's just
  rcu_read_lock()
- With CONFIG_MEMCG and inter memcg  task movement, it's
  rcu_read_lock() + spin_lock_irqsave()

A memcg parameter is added to several routines because their callers
now grab mem_cgroup_begin_page_stat() which returns the memcg later
needed by for mem_cgroup_update_page_stat().

Because mem_cgroup_begin_page_stat() may disable interrupts, some
adjustments are needed:
- move __mark_inode_dirty() from __set_page_dirty() to its caller.
  __mark_inode_dirty() locking does not want interrupts disabled.
- use spin_lock_irqsave(tree_lock) rather than spin_lock_irq() in
  __delete_from_page_cache(), replace_page_cache_page(),
  invalidate_complete_page2(), and __remove_mapping().

Maxime Ripard 4af34b572a drivers: soc: sunxi: Introduce SoC driver to map SRAMs
The Allwinner SoCs have a handful of SRAM that can be either mapped to be
accessible by devices or the CPU.

That mapping is controlled by an SRAM controller, and that mapping might
not be set by the bootloader, for example if the device wasn't used at all,
or if we're using solutions like the U-Boot's Falcon Boot.

We could also imagine changing this at runtime for example to change the
mapping of these SRAMs to use them for suspend/resume or runtime memory
rate change, if that ever happens.

These use cases require some API in the kernel to control that mapping,
exported through a drivers/soc driver.

This driver also implement a debugfs file that shows the SRAM found in the
system, the current mapping and the SRAM that have been claimed by some
drivers in the kernel.

Kuninori Morimoto 89d49a706c mmc: sh_mmcif: calculate best clock with parent clock
MMCIF IP on R-Car series has parent clock which can be set several rate,
and it was not implemented on old SH-Mobile series (= SH-Mobile series
parent clock was fixed rate) R-Car series MMCIF can use more high speed
access if it setups parent clock. This patch adds parent clock setup
method. It will be used if DT has "max-frequency", and then, this driver
assumes it is booted on R-Car Gen2 or later SoC. Because SH-Mobile series
(which doesn't boot from DT) and R-Car series (which boots from DT) have
different divider.

What's written there about the arguments for this ioctl
is bogus: it doesn't return an enum (or a typedef)

Also, the size of the integer returned is not 16 bits, but,
instead, sizeof(fe_status_t), e. g. sizeof(enum), with is

	open()
	close()
	ioctl FE_GET_INFO — Query DVB frontend capabilities and returns information about the front-end. This call only requires read-only access to the device
	ioctl FE_READ_STATUS — Returns status information about the front-end. This call only requires read-only access to the device
	ioctl FE_SET_PROPERTY, FE_GET_PROPERTY — FE_SET_PROPERTY sets one or more frontend properties. FE_GET_PROPERTY returns one or more frontend properties.
	ioctl FE_DISEQC_RESET_OVERLOAD — Restores the power to the antenna subsystem, if it was powered off due to power overload.
	ioctl FE_DISEQC_SEND_MASTER_CMD — Sends a DiSEqC command
	ioctl FE_DISEQC_RECV_SLAVE_REPLY — Receives reply from a DiSEqC 2.0 command
	ioctl FE_DISEQC_SEND_BURST — Sends a 22KHz tone burst for 2x1 mini DiSEqC satellite selection.
	ioctl FE_SET_TONE — Sets/resets the generation of the continuous 22kHz tone.
	ioctl FE_SET_VOLTAGE — Allow setting the DC level sent to the antenna subsystem.
	ioctl FE_ENABLE_HIGH_LNB_VOLTAGE — Select output DC level between normal LNBf voltages or higher LNBf voltages.

Yinghai Lu 3a9ad0b4fd PCI: Add pci_bus_addr_t
David Ahern reported that d63e2e1f3d ("sparc/PCI: Clip bridge windows
to fit in upstream windows") fails to boot on sparc/T5-8:

  pci 0000:06:00.0: reg 0x184: can't handle BAR above 4GB (bus address 0x110204000)

The problem is that sparc64 assumed that dma_addr_t only needed to hold DMA
addresses, i.e., bus addresses returned via the DMA API (dma_map_single(),
etc.), while the PCI core assumed dma_addr_t could hold *any* bus address,
including raw BAR values.  On sparc64, all DMA addresses fit in 32 bits, so
dma_addr_t is a 32-bit type.  However, BAR values can be 64 bits wide, so
they don't fit in a dma_addr_t.  d63e2e1f3d added new checking that
tripped over this mismatch.

Add pci_bus_addr_t, which is wide enough to hold any PCI bus address,
including both raw BAR values and DMA addresses.  This will be 64 bits
on 64-bit platforms and on platforms with a 64-bit dma_addr_t.  Then
dma_addr_t only needs to be wide enough to hold addresses from the DMA API.

least as wide as dma_addr_t, documentation]

Heinz Mauelshagen 0cf4503174 dm raid: add support for the MD RAID0 personality
Add dm-raid access to the MD RAID0 personality to enable single zone
striping.

The following changes enable that access:
- add type definition to raid_types array
- make bitmap creation conditonal in super_validate(), because
  bitmaps are not allowed in raid0
- set rdev->sectors to the data image size in super_validate()
  to allow the raid0 personality to calculate the MD array
  size properly
- use mdddev(un)lock() functions instead of direct mutex_(un)lock()
  (wrapped in here because it's a trivial change)
- enhance raid_status() to always report full sync for raid0
  so that userspace checks for 100% sync will succeed and allow
  for resize (and takeover/reshape once added in future paches)
- enhance raid_resume() to not load bitmap in case of raid0
- add merge function to avoid data corruption (seen with readahead)
  that resulted from bio payloads that grew too large.  This problem
  did not occur with the other raid levels because it either did not
  apply without striping (raid1) or was avoided via stripe caching.
- raise version to 1.7.0 because of the raid0 API change

Suzuki K. Poulose a95791efa7 arm-cci: Add CCI-500 PMU support
CCI-500 provides 8 event counters which can count any of the
supported events independently. The PMU event id is a 9-bit
value made of two parts.
	bits [8:5] - Source port
			0x0-0x6 Slave Ports
			0x8-0xD Master Ports
			0xf     Global Events to CCI
			0x7,0xe Reserved
	bits [0:4] - Event code (specific to each type of port)

The generic CCI-500 controlling interface remains the same with CCI-400.
However there are some differences in the PMU event counters.
 - No cycle counter
 - Upto 8 counters(4 in CCI-400)
 - Each counter area is 64K(4K in CCI400)
 - The counter0 starts at offset 0x10000 from the base of CCI

By default, with rcutorture.nreaders equal to -1, rcutorture provisions
N-1 reader kthreads, where N is the number of CPUs.  This avoids
rcutorture-induced stalls, but also avoids heavier levels of torture.
This commit therefore allows negative values of rcutorture.nreaders
to specify larger numbers of reader kthreads, so that for example
rcutorture.nreaders=-2 provisions N kthreads and rcutorture.nreaders=-5
provisions N+3 kthreads.

The CONFIG_RCU_FANOUT_EXACT Kconfig parameter is used primarily (and
perhaps only) by rcutorture to verify that RCU works correctly in specific
rcu_node combining-tree configurations.  It therefore does not make
much sense have this as a question to people attempting to configure
their kernels.  So this commit creates an rcutree.rcu_fanout_exact=
boot parameter that rcutorture can use, and eliminates the original
CONFIG_RCU_FANOUT_EXACT Kconfig parameter.

Paul E. McKenney 0f41c0ddad rcu: Provide diagnostic option to slow down grace-period scans
Grace-period scans of the rcu_node combining tree normally
proceed quite quickly, so that it is very difficult to reproduce
races against them.  This commit therefore allows grace-period
pre-initialization and cleanup to be artificially slowed down,
increasing race-reproduction probability.  A pair of pairs of new
Kconfig parameters are provided, RCU_TORTURE_TEST_SLOW_PREINIT to
enable the slowing down of propagating CPU-hotplug changes up the
combining tree along with RCU_TORTURE_TEST_SLOW_PREINIT_DELAY to
specify the delay in jiffies, and RCU_TORTURE_TEST_SLOW_CLEANUP
to enable the slowing down of the end-of-grace-period cleanup scan
along with RCU_TORTURE_TEST_SLOW_CLEANUP_DELAY to specify the delay
in jiffies.  Boot-time parameters named rcutree.gp_preinit_delay and
rcutree.gp_cleanup_delay allow these delays to be specified at boot time.

Paul E. McKenney 5af4692a75 smp: Make control dependencies work on Alpha, improve documentation
The current formulation of control dependencies fails on DEC Alpha,
which does not respect dependencies of any kind unless an explicit
memory barrier is provided.  This means that the current fomulation of
control dependencies fails on Alpha.  This commit therefore creates a
READ_ONCE_CTRL() that has the same overhead on non-Alpha systems, but
causes Alpha to produce the needed ordering.  This commit also applies
READ_ONCE_CTRL() to the one known use of control dependencies.

Use of READ_ONCE_CTRL() also has the beneficial effect of adding a bit
of self-documentation to control dependencies.

Will Deacon d956028e99 documentation: memory-barriers: Fix smp_mb__before_spinlock() semantics
Our current documentation claims that, when followed by an ACQUIRE,
smp_mb__before_spinlock() orders prior loads against subsequent loads
and stores, which isn't the intent.  This commit therefore fixes the
documentation to state that this sequence orders only prior stores
against subsequent loads and stores.

In addition, the original intent of smp_mb__before_spinlock() was to only
order prior loads against subsequent stores, however, people have started
using it as if it ordered prior loads against subsequent loads and stores.
This commit therefore also updates smp_mb__before_spinlock()'s header
comment to reflect this new reality.

Gregory CLEMENT 4dacccfac6 spi: orion: Fix extended baud rates for each Armada SoCs
The commit df59fa7f4b "spi: orion: support armada extended baud
rates" made the assumptions that all the Armada SoCs supported the
same maximum frequency. However, according the hardware datasheet, the
maximum frequency supported by the Armada 370 SoC is tclk/4, for the
Armada XP, Armada 38x and Armada 39x SoCs the limitation is 50MHz and
for the Armada 375 it is tclk/15.

This patch introduces new compatible strings to handle all these
case. In order to be future proof a compatible was created for each
SoC even if currently some SoCs seem using the same IP.

Eric Dumazet 07f4c90062 tcp/dccp: try to not exhaust ip_local_port_range in connect()
A long standing problem on busy servers is the tiny available TCP port
range (/proc/sys/net/ipv4/ip_local_port_range) and the default
sequential allocation of source ports in connect() system call.

If a host is having a lot of active TCP sessions, chances are
very high that all ports are in use by at least one flow,
and subsequent bind(0) attempts fail, or have to scan a big portion of
space to find a slot.

In this patch, I changed the starting point in __inet_hash_connect()
so that we try to favor even [1] ports, leaving odd ports for bind()
users.

We still perform a sequential search, so there is no guarantee, but
if connect() targets are very different, end result is we leave
more ports available to bind(), and we spread them all over the range,
lowering time for both connect() and bind() to find a slot.

This strategy only works well if /proc/sys/net/ipv4/ip_local_port_range
is even, ie if start/end values have different parity.

Therefore, default /proc/sys/net/ipv4/ip_local_port_range was changed to
32768 - 60999 (instead of 32768 - 61000)

There is no change on security aspects here, only some poor hashing
schemes could be eventually impacted by this change.

[1] : The odd/even property depends on ip_local_port_range values parity

Jyri Sarha 103cd8bc1c drm/tilcdc: Add support for external tda998x encoder
Add support for an external compontised DRM encoder. The external
encoder can be connected to tilcdc trough device tree graph binding.
The binding document for tilcdc has been updated. The current
implementation supports only tda998x encoder.

To be able to filter out the unsupported video modes the tilcdc driver
needs to hijack the external connectors helper functions. The tilcdc
installes new helper functions that are otherwise identical to
orignals, but the mode_valid() call-back check the mode first localy,
before calling the original call-back. The tilcdc dirver restores the
original helper functions before it is unbound from the external
device.

I got the idea and some lines of code from Jean-Francois Moine's
"drm/tilcdc: Change the interface with the tda998x driver"-patch.

Thomas Niederprüm c89eacfc70 fbdev: ssd1307fb: Unify init code and obtain hw specific bits from DT
The 130X controllers are very similar from the configuration point of view.
The configuration registers for the SSD1305/6/7 are bit identical (except the
the VHCOM register and the the default values for clock setup register). This
patch unifies the init code of the controller and adds hardware specific
properties to DT that are needed to correctly initialize the device.

The SSD130X can be wired to the OLED panel in various ways. Even for the
same controller this wiring can differ from one display module to another
and can not be probed by software. The added DT properties reflect these
hardware decisions of the display module manufacturer.
The 'com-sequential', 'com-lrremap' and 'com-invdir' values define different
possibilities for the COM signals pin configuration and readout direction
of the video memory. The 'segment-no-remap' allows the inversion of the
memory-to-pin mapping ultimately inverting the order of the controllers
output pins. The 'prechargepX' values need to be adapted according to the
capacitance of the OLEDs pixel cells.

So far these hardware specific bits are hard coded in the init code, making
the driver usable only for one certain wiring of the controller. This patch
makes the driver usable with all possible hardware setups, given a valid hw
description in DT. If these values are not set in DT the default values,
as they are set in the ssd1307 init code right now, are used. This implies
that without the corresponding DT property "segment-no-remap" the segment
remap of the ssd130X controller gets activated. Even though this is not the
default behaviour according to the datasheet it maintains backward
compatibility with older DTBs.

Note that the SSD1306 does not seem to be using the configuration written to
the registers at all. Therefore this patch does not try to maintain these
values without changes in DT. For reference an example is added to the DT
bindings documentation that reproduces the configuration that is set in the
current init code.

 binding from reaching v4.1-final, and an old fix for
 s3c2410-udc where pullup logic was reversed.

NeilBrown f5e4edb8c8 power: twl4030_charger: find associated phy by more reliable means.
twl4030_charger currently finds the associated phy
using usb_get_phy() which will return the first USB2 phy.
If your platform has multiple such phys (as mine does),
this is not reliable (and reliably fails on the GTA04).

Change to use devm_usb_get_phy_by_node(), having found the
node by looking for an appropriately named sibling in
device-tree.

This makes usb-charging dependent on correct device-tree
configuration.

Andre Przywara 0dd1e247fd drivers: PL011: add support for the ARM SBSA generic UART
The ARM Server Base System Architecture[1] document describes a
generic UART which is a subset of the PL011 UART.
It lacks DMA support, baud rate control and modem status line
control, among other things.
The idea is to move the UART initialization and setup into the
firmware (which does this job today already) and let the kernel just
use the UART for sending and receiving characters.

We use the recent refactoring to build a new struct uart_ops
variable which points to some new functions avoiding access to the
missing registers. We reuse as much existing PL011 code as possible.

In contrast to the PL011 the SBSA UART does not define any AMBA or
PrimeCell relations, so we go with a pretty generic probe function
which only uses platform device functions.
A DT binding is provided with this patch, ACPI support is added in a
separate one.

phy.c was a case of two changes, one adding a local

one.

tcp.c overlapped a deadlock fix with the addition of new tcp_info

macb.c involved the addition of two zyncq device entries.

skbuff.h involved adding back ipv4_daddr to nf_bridge_info

Jesper Dangaard Brouer 282fb58947 pktgen: add sample script pktgen_sample02_multiqueue.sh
Add the pktgen samples script pktgen_sample02_multiqueue.sh that
demonstrates generating packets on multiqueue NICs.

Specifically notice the options "-t" that specifies how many
kernel threads to activate.  Also notice the flag QUEUE_MAP_CPU,
which cause the SKB TX queue to be mapped to the CPU running the
kernel thread.  For best scalability people are also encourage to
map NIC IRQ /proc/irq/*/smp_affinity to CPU number.

Usage example with "-t" 4 threads and help:
 ./pktgen_sample02_multiqueue.sh -i eth4 -m 00:1B:21:3C:9D:F8 -t 4

Usage: ./pktgen_sample02_multiqueue.sh [-vx] -i ethX

  -s : ($PKT_SIZE)  packet size
  -d : ($DEST_IP)   destination IP
  -m : ($DST_MAC)   destination MAC-addr
  -t : ($THREADS)   threads to start
  -c : ($SKB_CLONE) SKB clones send before alloc new SKB
  -b : ($BURST)     HW level bursting of SKBs

Stefan Agner 8064887e02 ARM: vf610: enable Cortex-M4 configuration on Vybrid SoC
This patch allows to build the Kernel for Vybrid (VF6xx) SoC
when ARMv7-M CPU is selected. The resulting image runs on the
secondary Cortex-M4 core. This core has equally access to all
peripherals as the main Cortex-A5 core. However, there is no
resource control mechanism, hence when both cores are used
simultaneously, orthogonal device tree's are required.

The boot CPU is dependent on the SoC variant. The available
boards use mostly variants where the Cortex-A5 is the primary
and hence the boot CPU. Booting the secondary Cortex-M4 CPU
needs SoC specific registers written. There is no in kernel
support for this right now, a external userspace utility
called "m4boot" can be used to boot the kernel:

Luis R. Rodriguez f2411da746 driver-core: add driver module asynchronous probe support
Some init systems may wish to express the desire to have device drivers
run their probe() code asynchronously. This implements support for this
and allows userspace to request async probe as a preference through a
generic shared device driver module parameter, async_probe.

Implementation for async probe is supported through a module parameter
given that since synchronous probe has been prevalent for years some
userspace might exist which relies on the fact that the device driver
will probe synchronously and the assumption that devices it provides
will be immediately available after this.

Daniel Borkmann 492135557d tcp: add rfc3168, section 6.1.1.1. fallback
This work as a follow-up of commit f7b3bec6f5 ("net: allow setting ecn
via routing table") and adds RFC3168 section 6.1.1.1. fallback for outgoing
ECN connections. In other words, this work adds a retry with a non-ECN
setup SYN packet, as suggested from the RFC on the first timeout:

  [...] A host that receives no reply to an ECN-setup SYN within the
  normal SYN retransmission timeout interval MAY resend the SYN and
  any subsequent SYN retransmissions with CWR and ECE cleared. [...]

Schematic client-side view when assuming the server is in tcp_ecn=2 mode,
that is, Linux default since 2009 via commit 255cac91c3 ("tcp: extend
ECN sysctl to allow server-side only ECN"):

 1) Normal ECN-capable path:

    SYN ECE CWR ----->
                <----- SYN ACK ECE
            ACK ----->

 2) Path with broken middlebox, when client has fallback:

    SYN ECE CWR ----X crappy middlebox drops packet
                      (timeout, rtx)
            SYN ----->
                <----- SYN ACK
            ACK ----->

In case we would not have the fallback implemented, the middlebox drop
point would basically end up as:

    SYN ECE CWR ----X crappy middlebox drops packet
                      (timeout, rtx)
    SYN ECE CWR ----X crappy middlebox drops packet
                      (timeout, rtx)
    SYN ECE CWR ----X crappy middlebox drops packet
                      (timeout, rtx)

In any case, it's rather a smaller percentage of sites where there would
occur such additional setup latency: it was found in end of 2014 that ~56%
of IPv4 and 65% of IPv6 servers of Alexa 1 million list would negotiate
ECN (aka tcp_ecn=2 default), 0.42% of these webservers will fail to connect
when trying to negotiate with ECN (tcp_ecn=1) due to timeouts, which the
fallback would mitigate with a slight latency trade-off. Recent related
paper on this topic:

  Brian Trammell, Mirja Kühlewind, Damiano Boppart, Iain Learmonth,
  Gorry Fairhurst, and Richard Scheffenegger:
    "Enabling Internet-Wide Deployment of Explicit Congestion Notification."
    Proc. PAM 2015, New York.
  http://ecn.ethz.ch/ecn-pam15.pdf

Thus, when net.ipv4.tcp_ecn=1 is being set, the patch will perform RFC3168,
section 6.1.1.1. fallback on timeout. For users explicitly not wanting this
which can be in DC use case, we add a net.ipv4.tcp_ecn_fallback knob that
allows for disabling the fallback.

tp->ecn_flags are not being cleared in tcp_ecn_clear_syn() on output, but
rather we let tcp_ecn_rcv_synack() take that over on input path in case a
SYN ACK ECE was delayed. Thus a spurious SYN retransmission will not prevent
ECN being negotiated eventually in that case.

SMAP is enabled so that kernel is allowed to access this user page

Fix it by setting SMAP && !CR0.WP into shadow page's role and reset mmu
once CR4.SMAP is updated

Wei Chen f936779329 pinctrl: sirf: add sirf atlas7 pinctrl and gpio support
The Pinctrl module (ioc) controls the Pad's function select
(each pad can have 8 functions), Pad's Drive Strength, Pad's
Pull Select and Pad's Input Disable status.

The ioc has two modules, ioc_top & ioc_rtc. Both of these two
modules have function select/clear, Pull select and Drive
Strength registers. But only ioc_rtc has input-disable
registers. The Pads on ioc_top have to access ioc_rtc to set
their input-disable status and intpu-disable-value.

So have to use one ioc driver instance to drive these two
ioc modules at the same time, and each ioc module will be
treat as one bank on the "IOC Device".

The GPIO Controller controls the GPIO status if the Pad has
been config as GPIO by Pinctrl already. Includes the GPIO
Input/output, Interrupt type, Interrupt Status, and Set/Get
Values.
The GPIO pull up/down are controlled by Pinctrl.

There are 7 GPIO Groups and splited into 3 MACROs in atlas7.
The GPIO Groups in one MACRO share one GPIO controllers, each
GPIO Group are treated as one GPIO bank.

For example:
In VDIFM macro, there is one GPIO Controller, it has 3 banks
to control 3 gpio groups. Its gpio name space is from 0 to 95.

The Device Tree can be written as following:

gpio-ranges = <&pinctrl 0 0 0>,
<&pinctrl 32 0 0>,
<&pinctrl 64 0 0>;

gpio-ranges-group-names = "gnss_gpio_grp",
"lcd_vip_gpio_grp",
"sdio_i2s_gpio_grp";

bank#0 is from 0~31, the pins are from pinctrl's "gnss_gpio_grp".
bank#2 is from 32~63, the pins are from pinctrl's "lcd_vip_gpio_grp".
bank#3 is from 64~95, the pins are from pinctrl's "sdio_i2s_gpio_grp".

Antoine Tenart c1f86f2fde Documentation: bindings: move the Berlin clock documentation
The Berlin clock documentation was part of the Marvell Berlin SoC
documentation because the Berlin clock configuration was inside the
chip controller. With the recent rework of the chip and system
controller handling (now all sub-devices of the soc and system
controller nodes are registred with simple-mfd, and each device has its
own sub-node), the documentation of the Berlin clock driver can be moved
to the generic clock documentation directory.

Brian Norris 8947e396a8 Documentation: dt: mtd: replace "nor-jedec" binding with "jedec, spi-nor"
In commit 8ff16cf77c ("Documentation: devicetree: m25p80: add "nor-jedec"
binding"), we added a generic "nor-jedec" binding to catch all
mostly-compatible SPI NOR flash which can be detected via the READ ID
opcode (0x9F). This was discussed and reviewed at the time, however
objections have come up since then as part of this discussion:

  http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074

It seems the parties involved agree that "jedec,spi-nor" does a better
job of capturing the fact that this is SPI-specific, not just any NOR
flash.

This binding was only merged for v4.1-rc1, so it's still OK to change
the naming.

At the same time, let's move the documentation to a better name.

Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the
documentation.

not 0.0001.

Note that the v4l-utils divide the value by 1000 for the signal
strength suggesting that the 1/1000 is correct.

than TC_ACT_RECLASSIFY is returned, so this skb-counter doesn't
break hypothetical loops induced by something other than perpetual
TC_ACT_RECLASSIFY return values.

skb_act_clone is now identical to skb_clone, so just use that.

Tested with following (bogus) filter:
tc filter add dev eth0 parent ffff: \
 protocol ip u32 match u32 0 0 police rate 10Kbit burst \
 64000 mtu 1500 action reclassify

David S. Miller b04096ff33 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Four minor merge conflicts:

1) qca_spi.c renamed the local variable used for the SPI device
   from spi_device to spi, meanwhile the spi_set_drvdata() call
   got moved further up in the probe function.

2) Two changes were both adding new members to codel params
   structure, and thus we had overlapping changes to the
   initializer function.

3) 'net' was making a fix to sk_release_kernel() which is
   completely removed in 'net-next'.

4) In net_namespace.c, the rtnl_net_fill() call for GET operations
   had the command value fixed, meanwhile 'net-next' adjusted the
   argument signature a bit.

This also matches example merge resolutions posted by Stephen
Rothwell over the past two days.

Add optional DT properties to set open delay, sample delay and number

Johan Hovold 166a85e442 gpio: remove gpiod_sysfs_set_active_low
Remove gpiod_sysfs_set_active_low (and gpio_sysfs_set_active_low) which
allowed code to change the polarity of a gpio line even after it had
been exported through sysfs.

Drivers should not care, and generally does not know, about gpio-line
polarity which is a hardware feature that needs to be described by
firmware.

It is currently possible to define gpio-line polarity in device-tree and
acpi firmware or using platform data. Userspace can also change the
polarity through sysfs.

Note that drivers using the legacy gpio interface could still use
GPIOF_ACTIVE_LOW to change the polarity before exporting the gpio.

There are no in-kernel users of this interface.

Eduardo Valentin 9d0be7f481 thermal: support slope and offset coefficients
It is common to have a linear extrapolation from
the current sensor readings and the actual temperature
value. This is specially the case when the sensor
is in use to extrapolate hotspots.

This patch adds slope and offset constants for
single sensor linear extrapolation equation. Because
the same sensor can be use in different locations,
from board to board, these constants are added
as part of thermal_zone_params.

The constants are available through sysfs.

It is up to the device driver to determine
the usage of these values.

Mahesh Bandewar d22a5fc0c3 bonding: Implement user key part of port_key in an AD system.
The port key has three components - user-key, speed-part, and duplex-part.
The LSBit is for the duplex-part, next 5 bits are for the speed while the
remaining 10 bits are the user defined key bits. Get these 10 bits
from the user-space (through the SysFs interface) and use it to form the
admin port-key. Allowed range for the user-key is 0 - 1023 (10 bits). If
it is not provided then use zero for the user-key-bits (default).

It can set using following example code -

   # modprobe bonding mode=4
   # usr_port_key=$(( RANDOM & 0x3FF ))
   # echo $usr_port_key > /sys/class/net/bond0/bonding/ad_user_port_key

Mahesh Bandewar 7451495755 bonding: Allow userspace to set actors' macaddr in an AD-system.
In an AD system, the communication between actor and partner is the
business between these two entities. In the current setup anyone on the
same L2 can "guess" the LACPDU contents and then possibly send the
spoofed LACPDUs and trick the partner causing connectivity issues for
the AD system. This patch allows to use a random mac-address obscuring
it's identity making it harder for someone in the L2 is do the same thing.

This patch allows user-space to choose the mac-address for the AD-system.
This mac-address can not be NULL or a Multicast. If the mac-address is set
from user-space; kernel will honor it and will not overwrite it. In the
absence (value from user space); the logic will default to using the
masters' mac as the mac-address for the AD-system.

It can be set using example code below -

   # modprobe bonding mode=4
   # sys_mac_addr=$(printf '%02x:%02x:%02x:%02x:%02x:%02x' \
                    $(( (RANDOM & 0xFE) | 0x02 )) \
                    $(( RANDOM & 0xFF )) \
                    $(( RANDOM & 0xFF )) \
                    $(( RANDOM & 0xFF )) \
                    $(( RANDOM & 0xFF )) \
                    $(( RANDOM & 0xFF )))
   # echo $sys_mac_addr > /sys/class/net/bond0/bonding/ad_actor_system

Al Viro 680baacbca new ->follow_link() and ->put_link() calling conventions
a) instead of storing the symlink body (via nd_set_link()) and returning
an opaque pointer later passed to ->put_link(), ->follow_link() _stores_
that opaque pointer (into void * passed by address by caller) and returns
the symlink body.  Returning ERR_PTR() on error, NULL on jump (procfs magic
symlinks) and pointer to symlink body for normal symlinks.  Stored pointer
is ignored in all cases except the last one.

Storing NULL for opaque pointer (or not storing it at all) means no call
of ->put_link().

b) the body used to be passed to ->put_link() implicitly (via nameidata).
Now only the opaque pointer is.  In the cases when we used the symlink body
to free stuff, ->follow_link() now should store it as opaque pointer in addition
to returning it.

                       |                            |     input avail? no
                       |                            |     TTY_OTHER_CLOSED? yes
                       |                            |     return -EIO

Several conditions are required to trigger this race:
1. the ldisc read buffer must become full so the input worker exits
2. the read() count parameter must be >= 4096 so the ldisc read buffer
   is empty
3. the subsequent read() occurs before the kicked worker has processed
   more input

However, the underlying cause of the race is that data is pipelined, while
tty state is not; ie., data already written by the pty slave end is not
yet visible to the pty master end, but state changes by the pty slave end
are visible to the pty master end immediately.

Pipeline the TTY_OTHER_CLOSED state through input worker to the reader.
1. Introduce TTY_OTHER_DONE which is set by the input worker when
   TTY_OTHER_CLOSED is set and either the input buffers are flushed or
   input processing has completed. Readers/polls are woken when
   TTY_OTHER_DONE is set.
2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED.
3. A new input worker is started from pty_close() after setting
   TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be
   set if the last input worker is already finished (or just about to
   exit).

Remove tty_flush_to_ldisc(); no in-tree callers.

Alexei Starovoitov 62f64aed62 pktgen: introduce xmit_mode '<start_xmit|netif_receive>'
Introduce xmit_mode 'netif_receive' for pktgen which generates the
packets using familiar pktgen commands, but feeds them into
netif_receive_skb() instead of ndo_start_xmit().

Default mode is called 'start_xmit'.

It is designed to test netif_receive_skb and ingress qdisc
performace only. Make sure to understand how it works before
using it for other rx benchmarking.

Sample script 'pktgen.sh':
\#!/bin/bash
function pgset() {
  local result

  echo $1 > $PGDEV

  result=`cat $PGDEV | fgrep "Result: OK:"`
  if [ "$result" = "" ]; then
    cat $PGDEV | fgrep Result:
  fi
}

[ -z "$1" ] && echo "Usage: $0 DEV" && exit 1
ETH=$1

PGDEV=/proc/net/pktgen/kpktgend_0
pgset "rem_device_all"
pgset "add_device $ETH"

PGDEV=/proc/net/pktgen/$ETH
pgset "xmit_mode netif_receive"
pgset "pkt_size 60"
pgset "dst 198.18.0.1"
pgset "dst_mac 90:e2:ba:ff:ff:ff"
pgset "count 10000000"
pgset "burst 32"

PGDEV=/proc/net/pktgen/pgctrl
echo "Running... ctrl^C to stop"
pgset "start"
echo "Done"
cat /proc/net/pktgen/$ETH

Usage:
$ sudo ./pktgen.sh eth2
...
Result: OK: 232376(c232372+d3) usec, 10000000 (60byte,0frags)
  43033682pps 20656Mb/sec (20656167360bps) errors: 10000000

Raw netif_receive_skb speed should be ~43 million packet
per second on 3.7Ghz x86 and 'perf report' should look like:
  37.69%  kpktgend_0   [kernel.vmlinux]  [k] __netif_receive_skb_core
  25.81%  kpktgend_0   [kernel.vmlinux]  [k] kfree_skb
   7.22%  kpktgend_0   [kernel.vmlinux]  [k] ip_rcv
   5.68%  kpktgend_0   [pktgen]          [k] pktgen_thread_worker

If fib_table_lookup is seen on top, it means skb was processed
by the stack. To benchmark netif_receive_skb only make sure
that 'dst_mac' of your pktgen script is different from
receiving device mac and it will be dropped by ip_rcv

Jesper Dangaard Brouer f1f00d8ff6 pktgen: adjust flag NO_TIMESTAMP to be more pktgen compliant
Allow flag NO_TIMESTAMP to turn timestamping on again, like other flags,
with a negation of the flag like !NO_TIMESTAMP.

Also document the option flag NO_TIMESTAMP.

====================
pull-request: can-next 2015-05-06

this is a pull request of a seven patches for net-next/master.

Andreas Gröger contributes two patches for the janz-ican3 driver. In
the first patch, the documentation for already existing sysfs entries
is added, the second patch adds support for another module/firmware
variant. A patch by Shawn Landden makes the padding in the struct
can_frame explicit. The next 4 patches target the flexcan driver, the
first one is by David Jander adding some documentation, the reaming
three by me add more documentation and two small code cleanups.
