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."
Fix up trivial conflict in drivers/spi/spi-s3c64xx.c due to removed code
being changed.

Pull networking update from David Miller:
1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
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.
4) All protocols on ipv4 and ipv6 are now network namespace aware, and
all the compatability checks for initial-namespace-only protocols is
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.
6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
Protocol (MVRP) support, from David Ward.
7) Compute packet lengths more accurately in the packet scheduler, from
Eric Dumazet.

10) Fix default multicast group joining on ipv6, and add anti-spoofing
checks to 6to4 and 6rd. From Hannes Frederic Sowa.
11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
times, rearrange inet frag datastructures for better cacheline
locality, and move more operations outside of locking. From Jesper
Dangaard Brouer.
12) Instead of strict master <--> slave relationships, allow arbitrary
scenerios with "upper device lists". From Jiri Pirko.
13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
Pirko.
14) Add a BPF filter netfilter match target, from Willem de Bruijn.
15) Orphan and delete a bunch of pre-historic networking drivers from
Paul Gortmaker.
16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although
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.
19) Support SO_REUSEPORT, from Tom Herbert.
20) Allow locking a socket BPF filter, so that it cannot change after a
process drops capabilities.
21) Add VLAN filtering to bridge, from Vlad Yasevich.
22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
the ipv6 routes, from YOSHIFUJI Hideaki.

_PAGE_EXEC_4U is 0x1000, unfortunately the immedate field of the
'or' instruction is a signed 13-bit value. So the above actually
assembles into:
or REG, -4096, REG
completely corrupting the final PTE value.
Set it with a:
sethi %hi(_PAGE_EXEC_4U), TMP
or REG, TMP, REG
sequence instead.
This fixes "git gc" crashes on sun4u machines.

If our first THP installation for an MM is via the set_pmd_at() done
during khugepaged's collapsing we'll end up in tsb_grow() trying to do
a GFP_KERNEL allocation with several locks held.
Simply using GFP_ATOMIC in this situation is not the best option
because we really can't have this fail, so we'd really like to keep
this an order 0 GFP_KERNEL allocation if possible.
Also, doing the TSB allocation from khugepaged is a really bad idea
because we'll allocate it potentially from the wrong NUMA node in that
context.
So what we do is defer the hugepage TSB allocation until the first TLB
miss we take on a hugepage. This is slightly tricky because we have
to handle two unusual cases:
1) Taking the first hugepage TLB miss in the window trap handler.
We'll call the winfix_trampoline when that is detected.
2) An initial TSB allocation via TLB miss races with a hugetlb
fault on another cpu running the same MM. We handle this by
unconditionally loading the TSB we see into the current cpu
even if it's non-NULL at hugetlb_setup time.

Accomodate the possibility that the TSB might be NULL at
the point that update_mmu_cache() is invoked. This is
necessary because we will sometimes need to defer the TSB
allocation to the first fault that happens in the 'mm'.
Seperate out the hugepage PTE test into a seperate function
so that the logic is clearer.

Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo:
"This is part of on-going cleanups to remove / minimize usages of
workqueue interfaces which are deprecated and/or misleading.
This round drops a number of usages of [delayed_]work_pending(), which
are dangerous as they lack any form of synchronization and thus often
lead to buggy / unnecessary code. There are a couple legitimate use
cases in kernel. Hopefully, they can be converted and
[delayed_]work_pending() can be removed completely. Even if not,
removing most of misuses should make it more difficult to find
examples of misuses and thus slow down growth of them.

To use it, 'perf record' should group events when recording. And
then perf report parses the saved group relation from file header

[ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]
$ perf evlist --group

With this example, default perf report will show you each event
separately.
You can use --group option to enable event group view:

As you can see the Overhead column now contains both of ref-cycles
and cycles and header line shows group information also - 'anon
group { ref-cycles, cycles }'. The output is sorted by period of
group leader first.
- Initial GTK+ annotate browser, from Namhyung Kim.
- Add option for runtime switching perf data file in perf report,
just press 's' and a menu with the valid files found in the current
directory will be presented, from Feng Tang.
- Add support to display whole group data for raw columns, from Jiri
Olsa.
- Add per processor socket count aggregation in perf stat, from
Stephane Eranian.
- Add interval printing in 'perf stat', from Stephane Eranian.
- 'perf test' improvements
- Add support for wildcards in tracepoint system name, from Jiri
Olsa.
- Add anonymous huge page recognition, from Joshua Zhu.
- perf build-id cache now can show DSOs present in a perf.data file
that are not in the cache, to integrate with build-id servers being
put in place by organizations such as Fedora.
- perf top now shares more of the evsel config/creation routines with
'record', paving the way for further integration like 'top'
snapshots, etc.
- perf top now supports DWARF callchains.
- Fix mmap limitations on 32-bit, fix from David Miller.
- 'perf bench numa mem' NUMA performance measurement suite
- ... and lots of fixes, performance improvements, cleanups and other
improvements I failed to list - see the shortlog and git log for
details."

Pull irq core changes from Ingo Molnar:
"The biggest changes are the IRQ-work and printk changes from Frederic
Weisbecker, which prepare the code for 'full dynticks' (the ability to
stop or slow down the periodic tick arbitrarily, not just in idle time
as today):
- Don't stop tick with irq works pending. This fix is generally
useful and concerns archs that can't raise self IPIs.
- Flush irq works before CPU offlining.
- Introduce "lazy" irq works that can wait for the next tick to be
executed, unless it's stopped.
- Implement klogd wake up using irq work. This removes the ad-hoc
printk_tick()/printk_needs_cpu() hooks and make it working even in
dynticks mode.
- Cleanups and fixes."

Pull in 'net' to take in the bug fixes that didn't make it into
3.8-final.
Also, deal with the semantic conflict of the change made to
net/ipv6/xfrm6_policy.c A missing rt6->n neighbour release
was added to 'net', but in 'net-next' we no longer cache the
neighbour entries in the ipv6 routes so that change is not
appropriate there.

By just reversing the order memtest is using the test patterns,
an additional round to zero the memory is not necessary.
This might save up to a second or even more for setups which are
doing tests on every boot.
