memblock_steal tries to reserve physical memory during boot.
When the requested size is not aligned on the section size
then, the remaining memory available for lowmem becomes
unaligned on the section boundary. There is a issue with this,
which is discussed in the thread below.
https://lkml.org/lkml/2012/6/28/112
The final conclusion from the thread seems to
be align the memblock_steal calls on the SECTION boundary.
The issue comes out when LPAE is enabled, where the
section size is 2MB.
Boot tested this on OMAP5 evm with and without LPAE.

task_work_run() implementation had the side effect of enabling

The generic implementation of compat_sys_sendfile() has been introduced

Following commit 74838b7 (swiotlb: add the late swiotlb initialization
function with iotlb memory) the swiotlb_init_with_default_size() is a
static function. This patch changes the arm64 code to call
swiotlb_init() instead and use the default size of 64MB. It is assumed
that AArch64 platforms have enough RAM to afford the pre-allocated
swiotlb memory. It also removes the #ifdef around this call since
CONFIG_SWIOTLB is always enabled.

This patch fixes an assumption that cclk's initial divisor will always be 1 (or
0 in the register). TSCALE is always initialized on startup with a value of 4
regardless of the inital cclk divisor; so, we can't make the assumption without
making lots of other assumptions. The TPERIOD value is set with a value of the
current cclk (value / (HZ * TSCALE)) - 1; so, we need to adjust based on this
initial frequency and not use cclk's initial divisor for adjusting the tscale.

Commit 7d7e1eb (ARM: OMAP2+: Prepare for irqs.h removal) and commit ec2c082
(ARM: OMAP2+: Remove hardcoded IRQs and enable SPARSE_IRQ) updated the way
interrupts for OMAP2/3 devices are defined in the HWMOD data structures to
being an index plus a fixed offset (defined by OMAP_INTC_START). The definition
of the PMU interrupts on OMAP2/3 devices is missing the OMAP_INTC_START offset
and so this is causing the allocation of PMU interrupts to fail on OMAP2/3
devices. So add the offset to fix this.
This is patch is based upon Tony's master branch for OMAP.

- Some defconfig updates, mostly to enable new DT boards and a few drivers.
- New drivers using the pincontrol subsystem for dove, kirkwood and mvebu

Pull media updates from Mauro Carvalho Chehab:
"The first part of the media updates for Kernel 3.7.
This series contain:
- A major tree renaming patch series: now, drivers are organized
internally by their used bus, instead of by V4L2 and/or DVB API,
providing a cleaner driver location for hybrid drivers that
implement both APIs, and allowing to cleanup the Kconfig items and
make them more intuitive for the end user;
- Media Kernel developers are typically very lazy with their duties
of keeping the MAINTAINERS entries for their drivers updated. As
now the tree is more organized, we're doing an effort to add/update
those entries for the drivers that aren't currently orphan;
- Several DVB USB drivers got moved to a new DVB USB v2 core; the new
core fixes several bugs (as the existing one that got bitroted).
Now, suspend/resume finally started to work fine (at least with
some devices - we should expect more work with regards to it);
- added multistream support for DVB-T2, and unified the API for
DVB-S2 and ISDB-S. Backward binary support is preserved;
- as usual, a few new drivers, some V4L2 core improvements and lots
of drivers improvements and fixes.
There are some points to notice on this series:
1) you should expect a trivial merge conflict on your tree, with the
removal of Documentation/feature-removal-schedule.txt: this series
would be adding two additional entries there. I opted to not
rebase it due to this recent change;
2) With regards to the PCTV 520e udev-related breakage, I opted to
fix it in a way that the patches can be backported to 3.5 even
without your firmware fix patch. This way, Greg doesn't need to
rush backporting your patch (as there are still the firmware cache
and firmware path customization issues to be addressed there).
I'll send later a patch (likely after the end of the merge window)
reverting the rest of the DRX-K async firmware request, fully
restoring its original behaviour to allow media drivers to
initialize everything serialized as before for 3.7 and upper.
3) I'm planning to work on this weekend to test the DMABUF patches
for V4L2. The patches are on my queue for several Kernel cycles,
but, up to now, there is/was no way to test the series locally.
I have some concerns about this particular changeset with regards
to security issues, and with regards to the replacement of the old
VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
GPU drivers change. The Overlay API allows direct PCI2PCI
transfers from a media capture card into the GPU framebuffer, but
its API is crappy. Also, the only existing X11 driver that
implements it requires a XV extension that is not available
anymore on modern drivers. The DMABUF can do the same thing, but
with it is promising to be a properly-designed API. If I can
successfully test this series and be happy with it, I should be
asking you to pull them next week."

However, the ARM architecture has been using the RTC_LIB framework

Pull UAPI disintegration fixes from David Howells:
"There are three main parts:
(1) I found I needed some more fixups in the wake of testing Arm64
(some asm/unistd.h files had weird guards that caused problems -
mostly in arches for which I don't have a compiler) and some
__KERNEL__ splitting needed to take place in Arm64.
(2) I found that c6x was missing some __KERNEL__ guards in its
asm/signal.h. Mark Salter pointed me at a tree with a patch to
remove that file entirely and use the asm-generic variant instead.
(3) Lastly, m68k turned out to have a header installation problem due
to it lacking a kvm_para.h file.
The conditional installation bits for linux/kvm_para.h, linux/kvm.h
and linux/a.out.h weren't very well specified - and didn't work if
an arch didn't have the asm/ version of that file, but there *was*
an asm-generic/ version.
It seems the "ifneq $((wildcard ...),)" for each of those three
headers in include/kernel/Kbuild is invoked twice during header
installation, and the second time it matches on the just installed
asm-generic/kvm_para.h file and thus incorrectly installs
linux/kvm_para.h as well.
Most arches actually have an asm/kvm_para.h, so this wasn't
detectable in those."

Pull ADM Xen support from Konrad Rzeszutek Wilk:
Features:
* Allow a Linux guest to boot as initial domain and as normal guests
on Xen on ARM (specifically ARMv7 with virtualized extensions). PV

Bug-fixes:
* Fix compile linux-next fallout.
* Fix PVHVM bootup crashing.
The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports
ARMv7 platforms.
The goal in implementing this architecture is to exploit the hardware
as much as possible. That means use as little as possible of PV
operations (so no PV MMU) - and use existing PV drivers for I/Os
(network, block, console, etc). This is similar to how PVHVM guests
operate in X86 platform nowadays - except that on ARM there is no need
for QEMU. The end result is that we share a lot of the generic Xen
drivers and infrastructure.

ASoC: Additional updates for v3.7
A couple more updates for 3.7, enhancements to the ux500 and wm2000
drivers, a new driver for DA9055 and the support for regulator bypass
mode. With the exception of the DA9055 this has all had a chance to
soak in -next (the driver was added on Friday so should be in -next
today).
Convert the driver from the outdated omap_pm_set_max_mpu_wakeup_lat
API to the new PM QoS API.
Since the constraint is on the MPU subsystem, use the PM_QOS_CPU_DMA_LATENCY
class of PM QoS. The resulting MPU constraints are used by cpuidle to
decide the next power state of the MPU subsystem.
The I2C device latency timing is derived from the FIFO size and the
clock speed and so is applicable to all OMAP SoCs.

vpif_display relied on a 1-1 mapping of output and subdev. This is not
necessarily the case. Separate the two. So there is a list of subdevs
and a list of outputs. Each output refers to a subdev and has routing
information. An output does not have to have a subdev.
The initial output for each channel is set to the fist output.
Currently missing is support for associating multiple subdevs with
an output.

This adds optimized memset/bzero/page-clear routines for Niagara-4.
We basically can do what powerpc has been able to do for a decade (via
the "dcbz" instruction), which is use cache line clearing stores for
bzero and memsets with a 'c' argument of zero.
As long as we make the cache initializing store to each 32-byte
subblock of the L2 cache line, it works.
As with other Niagara-4 optimized routines, the key is to make sure to
avoid any usage of the %asi register, as reads and writes to it cost
at least 50 cycles.
For the user clear cases, we don't use these new routines, we use the
Niagara-1 variants instead. Those have to use %asi in an unavoidable
way.
A Niagara-4 8K page clear costs just under 600 cycles.
Add definitions of the MRU variants of the cache initializing store
ASIs. By default, cache initializing stores install the line as Least
Recently Used. If we know we're going to use the data immediately
(which is true for page copies and clears) we can use the Most
Recently Used variant, to decrease the likelyhood of the lines being
evicted before they get used.

Pull powerpc updates from Benjamin Herrenschmidt:
"Some highlights in addition to the usual batch of fixes:
- 64TB address space support for 64-bit processes by Aneesh Kumar
- Gavin Shan did a major cleanup & re-organization of our EEH support
code (IBM fancy PCI error handling & recovery infrastructure) which
paves the way for supporting different platform backends, along
with some rework of the PCIe code for the PowerNV platform in order
to remove home made resource allocations and instead use the
generic code (which is possible after some small improvements to it
done by Gavin).
- Uprobes support by Ananth N Mavinakayanahalli
- A pile of embedded updates from Freescale folks, including new SoC
and board supports, more KVM stuff including preparing for 64-bit
BookE KVM support, ePAPR 1.1 updates, etc..."

Make the location of compat_siginfo_t uniform across eight architectures
which have it. Now it can be pulled in by including asm/compat.h or

Most of the copies are verbatim. compat_uid[32]_t had to be replaced by

compat_siginfo_t in asm/compat.h on a several architectures (tile already
had it moved up). compat_sigval_t had to be relocated from linux/compat.h
to asm/compat.h.

Historically, the top three bytes of personality have been used for
things such as ADDR_NO_RANDOMIZE, which made sense only for specific
architectures.
We now however have a flag there that is general no matter the
architecture (UNAME26); generally we have to be careful to preserve the
personality flags across exec().
This patch fixes tile architecture not to forcefully overwrite
personality flags during exec().
In addition to that, we fix two other things along the way:
- exec_domain switching is fixed -- set_personality() should always
be used instead of directly assigning to current->personality.
- as pointed out by Arnd Bergmann, PER_LINUX_32BIT is not used anywhere
by tile, so let's just drop that in favor of PER_LINUX

The syscall tracing patch introduces a compile bug in lttng-modules

<path-to-linux>/arch/arm/include/asm/syscall.h:21:2: error: implicit declaration of function 'task_thread_info' [-Werror=implicit-function-declaration]
The issue is that we are using task_thread_info() in the
syscall_get_nr() function in asm/syscall.h, but not explicitly
including sched.h from this file, so we can expect this bug might
surface any time that syscall_get_nr() is called.
Explicitly including sched.h solves the problem.

After fixing a couple of brainos, it even seems to work. What's done here
is move of ->syscall_noerror right before FPDEPTH byte in ->flags and
using sth to [%g6 + TI_SYS_NOERROR] instead of stb to [%g6 + TI_FPDEPTH] in
both branches of etrap_save. AFAICS, that ought to be solid. Again,
deciding what to do with now unused delay slot of branch on ->syscall_noerror
and dealing with the order of tests in ret_from_sys is a separate question,
but at least that way we don't have to clean ->syscall_noerror in there at
all. AFAICS, it ought to be a clear win - sth is not going to cost more than
stb on etrap_64.S side of things, and we are losing write on syscalls.S one.

Note that there are some fixup patches which are at the base of the
branch aimed at you, plus all arches get the asm-generic branch merged in too.
* 'disintegrate-asm-generic' of git://git.infradead.org/users/dhowells/linux-headers:
UAPI: (Scripted) Disintegrate include/asm-generic
UAPI: Fix conditional header installation handling (notably kvm_para.h on m68k)
c6x: remove c6x signal.h
UAPI: Split compound conditionals containing __KERNEL__ in Arm64
UAPI: Fix the guards on various asm/unistd.h files

CROSS_COMPILE must be setup before using e.g. cc-option (and a few other
as-*, cc-*, ld-* macros), else they will check against the wrong compiler
when cross-compiling, and may invoke the cross compiler with wrong or
suboptimal compiler options.

The old method of registering with the ASoC core by creating a
"soc-audio" platform device no longer works for Amstrad Delta sound card
after recent changes to drvdata handling (commit
0998d06310, 'device-core: Ensure drvdata =
NULL when no driver is bound'.
Use snd_soc_register_card() method instead, as suggested by the ASoC
core generated warning message, and move both the card and codec
platform device registration to the arch board file where those belong.

This reverts commit 8b28626a6b.
Offset -8 is wrong because when it is applied then one instruction

Offset -4 is correct and brki instruction is called again.

The c6x signal.h includes the asm-generic version and provides
a couple of extern declarations. David Howells pointed out that
the externs needed to be protected by ifdef __KERNEL__. As it
turns out, the externs aren't really needed since the functions
are only called from asm code. So this patch gets rid of the
c6x signal.h and uses just the asm-generic version.

Register pfn_is_ram helper speed up reading /proc/vmcore in the kdump
kernel. See commit message of 997c136f51 ("fs/proc/vmcore.c: add hook
to read_from_oldmem() to check for non-ram pages") for details.
It makes use of a new hvmop HVMOP_get_mem_type which was introduced in
xen 4.2 (23298:26413986e6e0) and backported to 4.1.1.
The new function is currently only enabled for reading /proc/vmcore.
Later it will be used also for the kexec kernel. Since that requires
more changes in the generic kernel make it static for the time being.

When u-boot passes control over to Linux it places the Linux command
line between to the end of __init_end. When space between
__init_end and __bss_start is not COMMAND_LINE_SIZE then
the part of cmdline can be lost.
In extreme case if __init_end == __bss_start u-boot can't pass
any cmdline to Linux kernel.
This patch fix this issue by copying cmd line directly to
cmd_line char array which is placed in data section.

The following patch adds perf_event support for the Xeon-Phi
PMU, as documented in the "Intel Xeon Phi Coprocessor (codename:
Knights Corner) Performance Monitoring Units" manual.
Even though it is a co-processor, a Phi runs a full Linux
environment and can support performance counters.
This is just barebones support, it does not add support for
interesting new features such as the SPFLT intruction that
allows starting/stopping events without entering the kernel.
The PMU internally is just like that of an original Pentium, but
a "P6-like" MSR interface is provided. The interface is
different enough from a real P6 that it's not easy (or
practical) to re-use the code in perf_event_p6.c

asm-generic/unistd.h and a number of asm/unistd.h files have been given
reinclusion guards that allow the guard to be overridden if __SYSCALL is
defined. Unfortunately, these files define __SYSCALL and don't undefine it
when they've finished with it, thus rendering the guard ineffective.
The reason for this override is to allow the file to be #included multiple
times with different settings on __SYSCALL for purposes like generating syscall
tables.
The following guards are problematic:
arch/arm64/include/asm/unistd.h:#if !defined(__ASM_UNISTD_H) || defined(__SYSCALL)
arch/arm64/include/asm/unistd32.h:#if !defined(__ASM_UNISTD32_H) || defined(__SYSCALL)
arch/c6x/include/asm/unistd.h:#if !defined(_ASM_C6X_UNISTD_H) || defined(__SYSCALL)
arch/hexagon/include/asm/unistd.h:#if !defined(_ASM_HEXAGON_UNISTD_H) || defined(__SYSCALL)
arch/openrisc/include/asm/unistd.h:#if !defined(__ASM_OPENRISC_UNISTD_H) || defined(__SYSCALL)
arch/score/include/asm/unistd.h:#if !defined(_ASM_SCORE_UNISTD_H) || defined(__SYSCALL)
arch/tile/include/asm/unistd.h:#if !defined(_ASM_TILE_UNISTD_H) || defined(__SYSCALL)
arch/unicore32/include/asm/unistd.h:#if !defined(__UNICORE_UNISTD_H__) || defined(__SYSCALL)
include/asm-generic/unistd.h:#if !defined(_ASM_GENERIC_UNISTD_H) || defined(__SYSCALL)
On the assumption that the guards' ineffectiveness has passed unnoticed, just
remove these guards entirely.

The symbol "GPIO24_SSP1_SFRM" is defined in both mfp-pxa27x.h and
mfp-pxa25x.h. Since the macro is not actually used in the cm-x2xx.c

the headers should be fixed to not both define it, but for now

- On a preempt kernel we might switch CPUs in the middle of building

no longer falls within the local CPU's pool. Check for this and
fall back to the pool hint.
- We were missing a spin_unlock/spin_lock in one spot where we

Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of

There's no caller of pcibios_assign_resources() in the tree. It is
exported, so an out-of-tree module *could* call it, but no other arch
exports pcibios_assign_resources(), so it would have to be a CRIS-specific
module. I doubt such a caller exists.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

Pull vfs update from Al Viro:
- big one - consolidation of descriptor-related logics; almost all of
that is moved to fs/file.c
(BTW, I'm seriously tempted to rename the result to fd.c. As it is,
we have a situation when file_table.c is about handling of struct
file and file.c is about handling of descriptor tables; the reasons
are historical - file_table.c used to be about a static array of
struct file we used to have way back).
A lot of stray ends got cleaned up and converted to saner primitives,
disgusting mess in android/binder.c is still disgusting, but at least
doesn't poke so much in descriptor table guts anymore. A bunch of
relatively minor races got fixed in process, plus an ext4 struct file
leak.
- related thing - fget_light() partially unuglified; see fdget() in
there (and yes, it generates the code as good as we used to have).
- also related - bits of Cyrill's procfs stuff that got entangled into
that work; _not_ all of it, just the initial move to fs/proc/fd.c and
switch of fdinfo to seq_file.
- Alex's fs/coredump.c spiltoff - the same story, had been easier to
take that commit than mess with conflicts. The rest is a separate
pile, this was just a mechanical code movement.
- a few misc patches all over the place. Not all for this cycle,
there'll be more (and quite a few currently sit in akpm's tree)."
Fix up trivial conflicts in the android binder driver, and some fairly
simple conflicts due to two different changes to the sock_alloc_file()
interface ("take descriptor handling from sock_alloc_file() to callers"
vs "net: Providing protocol type via system.sockprotoname xattr of
/proc/PID/fd entries" adding a dentry name to the socket)

prom_printf() takes printf style arguments. Specifing GCC's format

This fixes those wrong format strings and arguments, and also leaves
format attributes in order to detect similar mistakes at compile time.

Pull CMA and DMA-mapping updates from Marek Szyprowski:
"This time the pull request is rather small, because the further
redesign patches were not ready on time.
This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem."
Fix up trivial add-add conflict due to the "dma-coherent" DT property
being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.
* 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:

ARM: add coherent iommu dma ops
ARM: add coherent dma ops
ARM: dma-mapping: Refrain noisy console message
ARM: dma-mapping: Small logical clean up
drivers: dma-contiguous: refactor dma_alloc_from_contiguous()
This function is used by sparc, powerpc and arm64 for compat support.
The patch adds a generic implementation which calls do_sendfile()
directly and avoids set_fs().
The sparc architecture has wrappers for the sign extensions while
powerpc relies on the compiler to do the this. The patch adds wrappers
for powerpc to handle the u32->int type conversion.
compat_sys_sendfile64() can be replaced by a sys_sendfile() call since
compat_loff_t has the same size as off_t on a 64-bit system.
On powerpc, the patch also changes the 64-bit sendfile call from
sys_sendile64 to sys_sendfile.

- Factoring out of the core hardware support from the MXS MMC driver by
Marek Vasut to allow the hardware to also be used for SPI.
- Lots of error handling cleanups from Guenter Roeck
- Removal of the existing Tegra driver which is quite comprehensively
broken as detailed in the changelog for the removal.

outgoing networking traffic. This benefits processes that have very
many mostly idle sockets, which is quite common.
From Eric Dumazet.
10) Use up to 32K for page fragment allocations, with fallbacks to
smaller sizes when higher order page allocations fail. Benefits are
a) less segments for driver to process b) less calls to page
allocator c) less waste of space.
From Eric Dumazet.

Pull user namespace changes from Eric Biederman:
"This is a mostly modest set of changes to enable basic user namespace
support. This allows the code to code to compile with user namespaces
enabled and removes the assumption there is only the initial user
namespace. Everything is converted except for the most complex of the
filesystems: autofs4, 9p, afs, ceph, cifs, coda, fuse, gfs2, ncpfs,
nfs, ocfs2 and xfs as those patches need a bit more review.
The strategy is to push kuid_t and kgid_t values are far down into
subsystems and filesystems as reasonable. Leaving the make_kuid and
from_kuid operations to happen at the edge of userspace, as the values
come off the disk, and as the values come in from the network.
Letting compile type incompatible compile errors (present when user
namespaces are enabled) guide me to find the issues.
The most tricky areas have been the places where we had an implicit
union of uid and gid values and were storing them in an unsigned int.
Those places were converted into explicit unions. I made certain to
handle those places with simple trivial patches.
Out of that work I discovered we have generic interfaces for storing
quota by projid. I had never heard of the project identifiers before.
Adding full user namespace support for project identifiers accounts
for most of the code size growth in my git tree.
Ultimately there will be work to relax privlige checks from
"capable(FOO)" to "ns_capable(user_ns, FOO)" where it is safe allowing
root in a user names to do those things that today we only forbid to
non-root users because it will confuse suid root applications.
While I was pushing kuid_t and kgid_t changes deep into the audit code
I made a few other cleanups. I capitalized on the fact we process
netlink messages in the context of the message sender. I removed
usage of NETLINK_CRED, and started directly using current->tty.
Some of these patches have also made it into maintainer trees, with no
problems from identical code from different trees showing up in
linux-next.
After reading through all of this code I feel like I might be able to
win a game of kernel trivial pursuit."

Plumb the UAPI Kbuilds into the user header installation and checking system.
As the headers are split the entries will be transferred across from the old
Kbuild files to the UAPI Kbuild files.
The changes made in this commit are:
(1) Exported generated files (of which there are currently four) are moved to
uapi/ directories under the appropriate generated/ directory, thus we
get:
include/generated/uapi/linux/version.h
arch/x86/include/generated/uapi/asm/unistd_32.h
arch/x86/include/generated/uapi/asm/unistd_64.h
arch/x86/include/generated/uapi/asm/unistd_x32.h
These paths were added to the build as -I flags in a previous patch.
(2) scripts/Makefile.headersinst is now given the UAPI path to install from
rather than the old path.
It then determines the old path from that and includes that Kbuild also
if it exists, thus permitting the headers to exist in either directory
during the changeover.
I also renamed the "install" variable to "installdir" as it refers to a
directory not the install program.
(3) scripts/headers_install.pl is altered to take a list of source file paths
instead of just their names so that the makefile can tell it exactly
where to find each file.
For the moment, files can be obtained from one of four places for each
output directory:
.../include/uapi/foo/
.../include/generated/uapi/foo/
.../include/foo/
.../include/generated/foo/
The non-UAPI paths will be dropped later.

Differentiate the generated UAPI and internal headers during generation such
that the UAPI headers can be installed elsewhere.
A later patch will use this to move the UAPI headers to:
arch/x86/include/generated/uapi/asm/
to make them easier to handle.
A previous patch added a -I for this path.

Fix a build failure in the x86 insn_sanity program after the UAPI split. The
problem is that insn_sanity.c #includes arch/x86/lib/insn.c - which uses the
kernel string header. This leads to conflicts for various definitions against
the /usr/include/ headers.
linux/string.h can be replaced with the normal userspace string.h if __KERNEL__
is not specified.

Partition the header include path flags into two sets, one for kernelspace
builds and one for userspace builds.
Add the following directories to build after the ordinary include directories
so that #include will pick up the UAPI header directly if the kernel header
has been moved there.
The userspace set (represented by the USERINCLUDE make variable) contains:
-I $(srctree)/arch/$(hdr-arch)/include/uapi
-I arch/$(hdr-arch)/include/generated/uapi
-I $(srctree)/include/uapi
-I include/generated/uapi
-include $(srctree)/include/linux/kconfig.h
and the kernelspace set (represented by the LINUXINCLUDE make variable)
contains:
-I $(srctree)/arch/$(hdr-arch)/include
-I arch/$(hdr-arch)/include/generated
-I $(srctree)/include
-I include --- if not building in the source tree
plus everything in the USERINCLUDE set.
Then use USERINCLUDE in building the x86 boot code.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

arch_is_coherent is problematic as it is a global symbol. This
doesn't work for multi-platform kernels or platforms which can support
per device coherent DMA.
This adds arm_coherent_dma_ops to be used for devices which connected
coherently (i.e. to the ACP port on Cortex-A9 or A15). The arm_dma_ops
are modified at boot when arch_is_coherent is true.

This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot of
driver/platform shared definitions have gone, such as platform data
structures. They now need to move out to a common location instead,
and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move and
once it settles in, we should be good for quite a while. Sorry for the
overhead.

A shorter cleanup branch submitted separately due to dependencies with
some of the previous topics.
Major thing here is that the Broadcom bcmring platform is removed. It's an
SoC that's used on some stationary VoIP platforms, and is in desperate
need of some cleanup. Broadcom came back and suggested that we just
deprecate the platform for now, since they aren't going to spend the
resources needed on cleaning it up, and there are no users of the platform
directly from mainline.

Most notable here is probably the addition of basic support for the
BCM2835, an SoC used in some of the Roku 2 players as well as the
much-hyped Raspberry Pi, cleaned up and contributed by Stephen
Warren. It's still early days on mainline support, with just the
basics working. But it has to start somewhere!
Beyond that there's some conversions of clock infrastructure on tegra
to common clock, misc updates for several other platforms, and OMAP
now has its own bus (under drivers/bus) to manage its devices through.
This branch adds two new directories outside of arch/arm:
drivers/irqchip for new irq controllers, and drivers/bus for the above
OMAP bus. It's expected that some of the other platforms will migrate
parts of their platforms to those directories over time as well.

This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used with
a mainline kernel. We have not been able to find anyone interested
in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra

Pull x86/smap support from Ingo Molnar:
"This adds support for the SMAP (Supervisor Mode Access Prevention) CPU
feature on Intel CPUs: a hardware feature that prevents unintended
user-space data access from kernel privileged code.
It's turned on automatically when possible.
This, in combination with SMEP, makes it even harder to exploit kernel
bugs such as NULL pointer dereferences."
Fix up trivial conflict in arch/x86/kernel/entry_64.S due to newly added
includes right next to each other.

Here is the big USB pull request for 3.7-rc1
There are lots of gadget driver changes (including copying a bunch of
files into the drivers/staging/ccg/ directory so that the other gadget
drivers can be fixed up properly without breaking that driver), and we
remove the old obsolete ub.c driver from the tree. There are also the
usual XHCI set of updates, and other various driver changes and updates.
We also are trying hard to remove the old dbg() macro, but the final
bits of that removal will be coming in through the networking tree
before we can delete it for good.

As we skipped the merge window for 3.6-rc1 for the tty tree, everything
is now settled down and working properly, so we are ready for 3.7-rc1.
Here's the patchset, it's big, but the large changes are removing a
firmware file and adding a staging tty driver (it depended on the tty
core changes, so it's going through this tree instead of the staging
tree.)

"The main new feature is machine support for System zEC12 including
transactional memory, runtime instrumentation, support for scm block
devices via eadm subchannels, and support for CEX4 crypto cards.
In addition there are some nice improvements: bpf jit compiler, arch
backend for cmpxchg_double, relative exception table entries, dasd
partition detection independent from the dasd driver ioctls, and cpu
cache information in /proc/cpuinfo and /sys/device/cpu.
And last but not least a series of cleanup patches from Heiko."

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf/x86: Fix typo in uncore_pmu_to_box
Pull perf update from Ingo Molnar:
"Lots of changes in this cycle as well, with hundreds of commits from
over 30 contributors. Most of the activity was on the tooling side.
Higher level changes:
- New 'perf kvm' analysis tool, from Xiao Guangrong.
- New 'perf trace' system-wide tracing tool
- uprobes fixes + cleanups from Oleg Nesterov.
- Lots of patches to make perf build on Android out of box, from
Irina Tirdea
- Extend ftrace function tracing utility to be more dynamic for its
users. It allows for data passing to the callback functions, as
well as reading regs as if a breakpoint were to trigger at function
entry.
The main goal of this patch series was to allow kprobes to use
ftrace as an optimized probe point when a probe is placed on an
ftrace nop. With lots of help from Masami Hiramatsu, and going
through lots of iterations, we finally came up with a good
solution.
- Add cpumask for uncore pmu, use it in 'stat', from Yan, Zheng.
- Various tracing updates from Steve Rostedt
- Clean up and improve 'perf sched' performance by elliminating lots
of needless calls to libtraceevent.
- Event group parsing support, from Jiri Olsa
- UI/gtk refactorings and improvements from Namhyung Kim
- Add support for non-tracepoint events in perf script python, from
Feng Tang
- Add --symbols to 'script', similar to the one in 'report', from
Feng Tang.
Infrastructure enhancements and fixes:
- Convert the trace builtins to use the growing evsel/evlist
tracepoint infrastructure, removing several open coded constructs
like switch like series of strcmp to dispatch events, etc.
Basically what had already been showcased in 'perf sched'.
- Add evsel constructor for tracepoints, that uses libtraceevent just
to parse the /format events file, use it in a new 'perf test' to
make sure the libtraceevent format parsing regressions can be more
readily caught.
- Some strange errors were happening in some builds, but not on the
next, reported by several people, problem was some parser related
files, generated during the build, didn't had proper make deps, fix
from Eric Sandeen.
- Introduce struct and cache information about the environment where
a perf.data file was captured, from Namhyung Kim.
- Fix handling of unresolved samples when --symbols is used in
'report', from Feng Tang.
- Add union member access support to 'probe', from Hyeoncheol Lee.
- Fixups to die() removal, from Namhyung Kim.
- Render fixes for the TUI, from Namhyung Kim.
- Don't enable annotation in non symbolic view, from Namhyung Kim.
- Fix pipe mode in 'report', from Namhyung Kim.
- Move related stats code from stat to util/, will be used by the
'stat' kvm tool, from Xiao Guangrong.
- Remove die()/exit() calls from several tools.
- Resolve vdso callchains, from Jiri Olsa
- Don't pass const char pointers to basename, so that we can
unconditionally use libgen.h and thus avoid ifdef BIONIC lines,
from David Ahern
- Refactor hist formatting so that it can be reused with the GTK
browser, From Namhyung Kim
- Fix build for another rbtree.c change, from Adrian Hunter.
- Make 'perf diff' command work with evsel hists, from Jiri Olsa.
- Use the only field_sep var that is set up: symbol_conf.field_sep,
fix from Jiri Olsa.
- .gitignore compiled python binaries, from Namhyung Kim.
- Get rid of die() in more libtraceevent places, from Namhyung Kim.
- Rename libtraceevent 'private' struct member to 'priv' so that it
works in C++, from Steven Rostedt
- Remove lots of exit()/die() calls from tools so that the main perf
exit routine can take place, from David Ahern
- Fix x86 build on x86-64, from David Ahern.
- {int,str,rb}list fixes from Suzuki K Poulose
- perf.data header fixes from Namhyung Kim
- Allow user to indicate objdump path, needed in cross environments,
from Maciek Borzecki
- Fix hardware cache event name generation, fix from Jiri Olsa
- Add round trip test for sw, hw and cache event names, catching the
problem Jiri fixed, after Jiri's patch, the test passes
successfully.
- Clean target should do clean for lib/traceevent too, fix from David
Ahern
- Check the right variable for allocation failure, fix from Namhyung
Kim
- Set up evsel->tp_format regardless of evsel->name being set
already, fix from Namhyung Kim
- Oprofile fixes from Robert Richter.
- Remove perf_event_attr needless version inflation, from Jiri Olsa
- Introduce libtraceevent strerror like error reporting facility,
from Namhyung Kim
- Add pmu mappings to perf.data header and use event names from cmd
line, from Robert Richter
- Fix include order for bison/flex-generated C files, from Ben
Hutchings
- Build fixes and documentation corrections from David Ahern
- Assorted cleanups from Robert Richter
- Let O= makes handle relative paths, from Steven Rostedt
- perf script python fixes, from Feng Tang.
- Initial bash completion support, from Frederic Weisbecker
- Allow building without libelf, from Namhyung Kim.
- Support DWARF CFI based unwind to have callchains when %bp based
unwinding is not possible, from Jiri Olsa.
- Symbol resolution fixes, while fixing support PPC64 files with an
.opt ELF section was the end goal, several fixes for code that
handles all architectures and cleanups are included, from Cody
Schafer.
- Assorted fixes for Documentation and build in 32 bit, from Robert
Richter
- Cache the libtraceevent event_format associated to each evsel
early, so that we avoid relookups, i.e. calling pevent_find_event
repeatedly when processing tracepoint events.
[ This is to reduce the surface contact with libtraceevents and
make clear what is that the perf tools needs from that lib: so
far parsing the common and per event fields. ]
- Don't stop the build if the audit libraries are not installed, fix
from Namhyung Kim.
- Fix bfd.h/libbfd detection with recent binutils, from Markus
Trippelsdorf.
- Improve warning message when libunwind devel packages not present,
from Jiri Olsa"

Pull RCU changes from Ingo Molnar:
0. 'idle RCU':
Adds RCU APIs that allow non-idle tasks to enter RCU idle mode and
provides x86 code to make use of them, allowing RCU to treat
user-mode execution as an extended quiescent state when the new
RCU_USER_QS kernel configuration parameter is specified. (Work is
in progress to port this to a few other architectures, but is not
part of this series.)
1. A fix for a latent bug that has been in RCU ever since the addition
of CPU stall warnings. This bug results in false-positive stall
warnings, but thus far only on embedded systems with severely
cut-down userspace configurations.
2. Further reductions in latency spikes for huge systems, along with
additional boot-time adaptation to the actual hardware.
This is a large change, as it moves RCU grace-period initialization
and cleanup, along with quiescent-state forcing, from softirq to a
kthread. However, it appears to be in quite good shape (famous
last words).
3. Updates to documentation and rcutorture, the latter category
including keeping statistics on CPU-hotplug latencies and fixing
some initialization-time races.
4. CPU-hotplug fixes and improvements.
5. Idle-loop fixes that were omitted on an earlier submission.
6. Miscellaneous fixes and improvements
In certain RCU configurations new kernel threads will show up (rcu_bh,
rcu_sched), showing RCU processing overhead.

Besides the CPU and DDR PLLs, the CPU and DDR frequencies
can be derived from other PLLs in the SRIF block on the
AR934x SoCs. The current code does not checks if the SRIF
PLLs are used and this can lead to incorrectly calculated
CPU/DDR frequencies.
Fix it by calculating the frequencies from SRIF PLLs if
those are used on a given board.

The current dividers in the code are wrong and this
leads to broken CPU frequency calculation on boards
where the fractional part is used.
For example, if the SoC is running from a 40MHz
reference clock, refdiv=1, nint=14, outdiv=0 and
nfrac=31 the real frequency is 579.375MHz but the
current code calculates 569.687MHz instead.
Because the system time is indirectly related to
the CPU frequency the broken computation causes
drift in the system time.
The correct divider is 2^6 for the CPU PLL and 2^10
for the DDR PLL. Use the correct values to fix the
issue.

While calculating the mac address the pointer for the current octet was
never reset back to the least significant one after being decremented
because of an octet overflow. This resulted in the code continuing to
increment at the current octet, potentially generating duplicate or
invalid mac addresses.
As a second issue the pointer was allowed to advance up to the most
significant octet, modifying the OUI, and potentially changing the type
of mac address.
Rewrite the code so it resets the pointer to the least significant
in each outer loop step, and bails out when the least significant octet
of the OUI is reached.

The tricky part here is that task_pt_regs() on m68k works *only* for
process inside do_signal(). However, we need something much simpler -
pt_regs of a process inside do_signal() may be at different offsets
from the stack bottom, depending on the way we'd entered the kernel,
but for a task inside sys_execve() it *is* at constant offset.
Moreover, for a kernel thread about to become a userland process the
same location is also fine - setting sp to that will leave the kernel
stack pointer at the very bottom of the kernel stack when we finally
switch to userland.

The stack frame "format" field needs to be explicitly set on thread creation
on ColdFire. For a normal long word aligned user stack pointer the frame
format is 0x4.
We were doing this for non-MMU ColdFire, but not for the case with MMU enabled.
So fix it so we always do it if targeting ColdFire.
The old code happend to rely on the stack frame format being inhereted from
the process calling exec. Furture changes means that may not always work,
so we really do want to set it explicitly.

... no need to read current_thread_info()->task only to
feed it to task_thread_page() immediately afterwards.
Moreover, not using current_thread_info() at all ends
up with better assembler - we need a location very close
to the top of kernel stack page and it's actually better
to do or with 0x1fff, followed be subtracting a small
constant than and with ~0x1fff, followed by adding a large
one. Both & and | would be a couple of insns (mvn lsr/mvn lsl

ARM: OMAP5: Enable arch timer support
ARM: OMAP: Add initialisation for the real-time counter.
The ACPI BGRT driver accesses the BIOS logo image when it initializes.
However, ACPI 5.0 (which introduces the BGRT) recommends putting the
logo image in EFI boot services memory, so that the OS can reclaim that
memory. Production systems follow this recommendation, breaking the
ACPI BGRT driver.
Move the bulk of the BGRT code to run during a new EFI late
initialization phase, which occurs after switching EFI to virtual mode,
and after initializing ACPI, but before freeing boot services memory.
Copy the BIOS logo image to kernel memory at that point, and make it
accessible to the BGRT driver. Rework the existing ACPI BGRT driver to
act as a simple wrapper exposing that image (and the properties from the
BGRT) via sysfs.

The EFI initialization creates virtual mappings for EFI boot services
memory, so if a driver wants to access EFI boot services memory, it
cannot call ioremap itself; doing so will trip the WARN about mapping
RAM twice. Thus, a driver accessing EFI boot services memory must do so
via the existing mapping already created during EFI intiialization.
Since the EFI code already maintains a memory map for that memory, add a
function efi_lookup_mapped_addr to look up mappings in that memory map.

Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
into asm-generic/module.h for all arches bar MIPS.
Also, use the generic definition mod_arch_specific where possible.
To this end, I've defined three new config bools:
(*) HAVE_MOD_ARCH_SPECIFIC
Arches define this if they don't want to use the empty generic
mod_arch_specific struct.
(*) MODULES_USE_ELF_RELA
Arches define this if their modules can contain RELA records. This causes
the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
defined by the arch rather than have the core emit an error message.
(*) MODULES_USE_ELF_REL
Arches define this if their modules can contain REL records. This causes
the Elf_Rel mapping to be emitted and allows apply_relocate() to be
defined by the arch rather than have the core emit an error message.
Note that it is possible to allow both REL and RELA records: m68k and mips are
two arches that do this.

The userspace part of UML uses the asm-offsets.h generator mechanism to
create definitions for UM_KERN_<LEVEL> that match the in-kernel
KERN_<LEVEL> constant definitions.
As of commit 04d2c8c83d ("printk: convert
the format for KERN_<LEVEL> to a 2 byte pattern"), KERN_<LEVEL> is no
longer expanded to the literal '"<LEVEL>"', but to '"\001" "LEVEL"', i.e.
it contains two parts.
However, the combo of DEFINE_STR() in
arch/x86/um/shared/sysdep/kernel-offsets.h and sed-y in Kbuild doesn't
support string literals consisting of multiple parts. Hence for all
UM_KERN_<LEVEL> definitions, only the SOH character is retained in the actual
definition, while the remainder ends up in the comment. E.g. in
include/generated/asm-offsets.h we get
#define UM_KERN_INFO "\001" /* "6" KERN_INFO */
instead of
#define UM_KERN_INFO "\001" "6" /* KERN_INFO */
This causes spurious '^A' output in some kernel messages:

To fix this:
- Move the mapping from UM_KERN_<LEVEL> to KERN_<LEVEL> from
arch/um/include/shared/common-offsets.h to
arch/um/include/shared/user.h, which is preincluded for all userspace
parts,
- Preinclude include/linux/kern_levels.h for all userspace parts, to
obtain the in-kernel KERN_<LEVEL> constant definitions. This doesn't
violate the kernel/userspace separation, as include/linux/kern_levels.h
is self-contained and doesn't expose any other kernel internals.
- Remove the now unused STR() and DEFINE_STR() macros.

There is no fundamental reason why we should switch SMEP and SMAP on
during early cpu initialization just to switch them off again. Now
with %eflags and %cr4 forced to be initialized to a clean state, we
only need the one-way enable. Also, make the functions inline to make
them (somewhat) harder to abuse.
This does mean that SMEP and SMAP do not get initialized anywhere near
as early. Even using early_param() instead of __setup() doesn't give
us control early enough to do this during the early cpu initialization
phase. This seems reasonable to me, because SMEP and SMAP should not
matter until we have userspace to protect ourselves from, but it does
potentially make it possible for a bug involving a "leak of
permissions to userspace" to get uncaught.

Unfortunately with CONFIG_LOCK_STAT=y lockdep will read & write to percpu
data very early in boot, prior to us initialising the percpu areas,
leading to a crash.
We have been getting away with this because the data_offset was previously
set to zero. This causes lockdep to read & write to the initial copy of
the percpu variables, which are discarded later in boot.
Although that is "fishy", it does work, and for lock statistics it is no
big deal to discard the counts from early boot.
So set the paca->data_offset = 0 for the boot cpu paca only.

effect, but the kernel would crash when turning paging on.
A similar argument applies to %eflags, and since we have to look for

and ticking as long as the CPUs are online).
This patch introduces a registration mechanism for the delay timer
(which provides an unconditional read_current_timer implementation) and
updates the architected timer code to use the new interface.
