Pull x86 cpu updates from Peter Anvin:
"This is a corrected attempt at the x86/cpu branch, this time with the
fixes in that makes it not break on KVM (current or past), or any
other virtualizer which traps on this configuration.
Again, the biggest change here is enabling the WC+ memory type on AMD
processors, if the BIOS doesn't."

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 update from Martin Schwidefsky:
"The most prominent change in this patch set is the software dirty bit
patch for s390. It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
the page_test_and_clear_dirty primitive which makes the common memory
management code a bit less obscure.
Heiko fixed most of the PCI related fallout, more often than not
missing GENERIC_HARDIRQS dependencies. Notable is one of the 3270
patches which adds an export to tty_io to be able to resize a tty.
The rest is the usual bunch of cleanups and bug fixes."

This provides a band-aid to provide stable page writes on jbd without
needing to backport the fixed locking and page writeback bit handling
schemes of jbd2. The band-aid works by using bounce buffers to snapshot
page contents instead of waiting.
For those wondering about the ext3 bandage -- fixing the jbd locking
(which was done as part of ext4dev years ago) is a lot of surgery, and
setting PG_writeback on data pages when we actually hold the page lock
dropped ext3 performance by nearly an order of magnitude. If we're
going to migrate iscsi and raid to use stable page writes, the
complaints about high latency will likely return. We might as well
centralize their page snapshotting thing to one place.

On cris-linux-gcc, __SIZE_TYPE__ expands to "unsigned int", as
gcc-4.6.3-nolibc/cris-linux/lib/gcc/cris-linux/4.6.3/plugin/include/config/cris/linux.h
has
#define SIZE_TYPE "unsigned int"
Hence __kernel_size_t is also "unsigned int". But __kernel_ssize_t is
"long", which has a different base type, causing compiler warnings like:
fs/quota/quota_tree.c:372:4: warning: format '%zd' expects argument of type 'signed size_t', but argument 4 has type 'ssize_t' [-Wformat]
To fix this, __kernel_ssize_t should be changed to "int". Hence cris can
just use the generic 32-bit versions from include/asm-generic/posix_types.h
for all size-related types.

Pull ARM virtualization changes:
"This contains parts of the ARM KVM support that have dependencies on
other patches merged through the arm-soc tree. In combination with
patches coming through Russell's tree, this will finally add full
support for the kernel based virtual machine on ARM, which has been
awaited for some time now.
Further, we now have a separate platform for virtual machines and qemu
booting that is used by both Xen and KVM, separating these from the
Versatile Express reference implementation. Obviously, this new
platform is multiplatform capable so it can be combined with existing
machines in the same kernel."

Pull sh-mobile pinctrl conversion from Arnd Bergmann:
"This is another cleanup series, containing the move of the Renesas
SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
generic pinctrl subsystem, changing it over to the common interfaces
in the process.
Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
we're merging this large branch of pinctrl conversion through arm-soc,
even though it contains the corresponding conversions for arch/sh.
Main reason for this is tight dependencies (that will now mostly be
broken) between the arch/sh and mach-shmobile implementations.
There will be more of this in 3.10 to do device-tree bindings, but
this is the initial conversion."

Pull ARM SoC cleanups from Arnd Bergmann:
"A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even
specify the driver they use, it can all get configured from the device
tree as we do for normal device drivers. The clocksource changes
basically touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose their
headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code."

Pull sound updates from Takashi Iwai:
"The biggest change in this update is the unification of HD-audio codec
parsers. Now the HD-audio codec is parsed in a generic parser code
which is invoked by each HD-audio codec driver.
Some background information is found in David Henningsson's blog
entry:
http://voices.canonical.com/david.henningsson/2013/01/18/upcoming-changes-to-the-intel-hda-drivers/
Other than that, some random updates/fixes like USB-audio and a bunch
of small AoC updates as usual.
Highlights:
- Unification of HD-audio parser code (aka generic parser)
- Support of new Intel HD-audio controller, new IDT codecs
- Fixes for HD-audio HDMI audio hotplug
- Haswell HDMI audio fixup
- Support of Creative CA0132 DSP code
- A few fixes of HDSP driver
- USB-audio fix for Roland A-PRO, M-Audio FT C600
- Support PM for aloop driver (and fixes Oops)
- Compress API updates for gapless playback support
For ASoC part:
- Support for a wider range of hardware in the compressed stream code
- The ability to mute capture streams as well as playback streams
while inactive
- DT support for AK4642, FSI, Samsung I2S and WM8962
- AC'97 support for Tegra
- New driver for max98090, replacing the stub which was there
- A new driver from Dialog
Note that due to dependencies, DTification of DMA support for Samsung
platforms (used only by the and I2S driver and SPI) is merged here as
well."

timestamp offset. From Andrey Vagin.
2) VMWARE VM VSOCK layer, from Andy King.
3) Much improved support for virtual functions and SR-IOV in bnx2x,
from Ariel ELior.

removed. Thanks to Tom Parkin for helping deal with the last major
holdout, L2TP.
5) IPV6 support in netpoll and network namespace support in pktgen,
from Cong Wang.

Protocol (MVRP) support, from David Ward.

times, rearrange inet frag datastructures for better cacheline
locality, and move more operations outside of locking. From Jesper
Dangaard Brouer.

scenerios with "upper device lists". From Jiri Pirko.
13) Improve rate limiting accuracy in TBF and act_police, also from Jiri

this still needs some minor bug fixing before it's %100 correct in
all cases.
17) Handle unresolved IPSEC states like ARP, with a resolution packet
queue. From Steffen Klassert.
18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
Hemminger. This was long overdue.

20) Allow locking a socket BPF filter, so that it cannot change after a
process drops capabilities.

Process personality is stored together with other flags like UNAME26 in
an integer variable. Overwriting this value with PER_LINUX drops all
other existing flags and as such broke tools like the uname26 tool.
Actually this was only broken on 32bit kernels, since for 32bit-ELF
binaries on 64-bit kernels the SET_PERSONALITY macro from
arch/parisc/kernel/binfmt_elf32.c is used which does not modifies the
personality value at all (which is wrong as long as we don't run HPUX
binaries or similiar).

1) PTRACE_SYSCALL doesn't work for 64bit process on parisc64.
Compat syscall table is used instead of 64bit one. IMO we should either
refuse to allow PTRACE_SYSCALL for 64bit processes or duplicate the
logics choosing the right syscall table into .Ltracesys.
2) if you have let the tracee run with PTRACE_SYSCALL and
it had stopped, you can use PTRACE_POKEUSR to modify syscall number
(r20) and arguments 1--4 (r26--r23). Modifications will have effect.
However, modifying arguments 5 and 6 (r22 and r21 resp.) works only
when process (32bit one) runs on 64bit host - on 32bit one it has no
effect. AFAICS, the diff below should fix that one.
