Pull MTD changes from David Woodhouse:

Fix up various trivial conflicts, largely due to changes in calling
conventions for things like dmaengine_prep_slave_sg() (new inline
wrapper to hide new parameter, clashing with rewrite of previously last
parameter that used to be an 'append' flag, and is now a bitmap of
'unsigned long flags').

(Also some header file fallout - like so many merges this merge window -
and silly conflicts with sparse fixes)

86dfe446c2 ARM: fix builds due to missing <asm/system_misc.h> includes
This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.

I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

5a4f5da543 ARM: 7337/1: ptrace: fix ptrace_read_user for !CONFIG_MMU platforms
Commit 68b7f715 ("nommu: ptrace support") added definitions for
PT_TEXT_ADDR and friends, as well as adding ptrace support for reading
from these magic offsets.

Unfortunately, this has probably never worked, since ptrace_read_user
predicates reading on off < sizeof(struct user), returning -EIO
otherwise.

This patch moves the offset size check until after we have tried to
match it against either a magic value or an offset into pt_regs.

804d231230 ARM: pxa: fix build failure for regulator consumer in em-x270.c
Commit 737f360d5b

"regulator: Remove support for supplies specified by struct device"

caused this file to break, since it was still relying on the
device field to be present.  Map it onto dev_name appropriately

Since there are two consumers with the name "reg-userspace-consumer",
we have to supply the ID as a suffix in the REGULATOR_CONSUMER calls.

3fc498f165 smp: introduce a generic on_each_cpu_mask() function
We have lots of infrastructure in place to partition multi-core systems
such that we have a group of CPUs that are dedicated to specific task:
cgroups, scheduler and interrupt affinity, and cpuisol= boot parameter.
Still, kernel code will at times interrupt all CPUs in the system via IPIs
for various needs.  These IPIs are useful and cannot be avoided
altogether, but in certain cases it is possible to interrupt only specific
CPUs that have useful work to do and not the entire system.

This patch set, inspired by discussions with Peter Zijlstra and Frederic
Weisbecker when testing the nohz task patch set, is a first stab at trying
to explore doing this by locating the places where such global IPI calls
are being made and turning the global IPI into an IPI for a specific group
of CPUs.  The purpose of the patch set is to get feedback if this is the
right way to go for dealing with this issue and indeed, if the issue is
even worth dealing with at all.  Based on the feedback from this patch set
I plan to offer further patches that address similar issue in other code
paths.

This patch creates an on_each_cpu_mask() and on_each_cpu_cond()
infrastructure API (the former derived from existing arch specific
versions in Tile and Arm) and uses them to turn several global IPI
invocation to per CPU group invocations.

Core kernel:

on_each_cpu_mask() calls a function on processors specified by cpumask,
which may or may not include the local processor.

You must not call this function with disabled interrupts or from a
hardware interrupt handler or from a bottom half handler.

arch/arm:

Note that the generic version is a little different then the Arm one:

1. It has the mask as first parameter
2. It calls the function on the calling CPU with interrupts disabled,
   but this should be OK since the function is called on the other CPUs
   with interrupts disabled anyway.

arch/tile:

The API is the same as the tile private one, but the generic version
also calls the function on the with interrupts disabled in UP case

This is OK since the function is called on the other CPUs
with interrupts disabled.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

Merge branch 'fixes-non-critical' into next/drivers2

fixes-non-critical has already been merged upstream, and there are a
handful of annoying context conflicts that it makes sense to resolve
before sending up. Part of this is because there was parallel development
going on between more urgent fixes and general driver fixups, it should
settle down once the lpc32xx platform reaches a more steady state.

Conflicts:
	arch/arm/mach-lpc32xx/clock.c
	arch/arm/mach-lpc32xx/common.h

9e4db1c3ee Merge branch 'platforms' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM platform updates from Russell King:
 "This covers platform stuff for platforms I have a direct interest in
  (iow, I have the hardware).  Essentially:
   - as we no longer support any other Acorn platforms other than RiscPC
     anymore, we can collect all that code into mach-rpc.
   - convert Acorn expansion card stuff to use IRQ allocation functions,
     and get rid of NO_IRQ from there.
   - cleanups to the ebsa110 platform to move some private stuff out of
     its header files.
   - large amount of SA11x0 updates:
   - conversion of private DMA implementation to DMA engine support
     (this actually gives us greater flexibility in drivers over the old
     API.)
   - re-worked ucb1x00 updates - convert to genirq, remove sa11x0
     dependencies, fix various minor issues
   - move platform specific sa11x0 framebuffer data into platform files
     in arch/arm instead of keeping this in the driver itself
   - update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
     for SIR transmissions as well as FIR
   - rework sa1111 support for genirq, and irq allocation
   - fix sa1111 IRQ support so it works again
   - use sparse IRQ support

  After this, I have one more pull request remaining from my current
  set, which I think is going to be the most problematical as it
  generates 8 conflicts."

Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

46b407ca4a remoteproc/rpmsg: new subsystem
This new subsystem provides a common way to talk to secondary processors
 on an SoC, e.g. a DSP, GPU or service processor, using virtio as the
 transport. In the long run, it should replace a few dozen vendor
 specific ways to do the same thing, which all never made it into the
 upstream kernel. There is a broad agreement that rpmsg is the way to
 go here and several vendors have started working on replacing their
 own subsystems.
 
 Two branches each add one virtio protocol number. Fortunately the
 numbers were agreed upon in advance, so there are only context changes.

Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: SoC specific updates" from Arnd Bergmann:
 "These changes are all specific to an soc family or the code for one
  soc.  Lots of work for Tegra3 this time, but also a lot of other
  platforms.  There will be another (smaller) set of soc patches later
  in the merge window for stuff that has dependencies on external trees
  or that was sent just before the merge window opened.

  The asoc tree added a few devices to the i.mx platform, which conflict
  with other devices added in the same place here.

  The tegra Makefile conflicts between a number of branches, mostly
  because of changes regarding localtimer.c, which was removed in the
  end.

This patch is part of a set which fixes unnecessary flash erase and write errors
resulting from the MTD CFI driver turning off vpp while an erase is in progress.
This patch allows physmap_set_vpp() calls to be nested by adding a reference
counter.

omap1_set_vpp() already used a reference counter. Since it is called from
physmap_set_vpp(), omap1_set_vpp() can now be simplified.

simtec_nor_vpp() already disabled hard interrupts. Since it is called from
physmap_set_vpp(), simtec_nor_vpp() can now be simplified.

ed2d265d12 The following text was taken from the original review request:
"[RFC - PATCH 0/7] consolidation of BUG support code."
 		https://lkml.org/lkml/2012/1/26/525
 --
 
 The changes shown here are to unify linux's BUG support under
 the one <linux/bug.h> file.  Due to historical reasons, we have
 some BUG code in bug.h and some in kernel.h -- i.e. the support for
 BUILD_BUG in linux/kernel.h predates the addition of linux/bug.h,
 but old code in kernel.h wasn't moved to bug.h at that time.  As
 a band-aid, kernel.h was including <asm/bug.h> to pseudo link them.
 
 This has caused confusion[1] and general yuck/WTF[2] reactions.
 Here is an example that violates the principle of least surprise:
 
       CC      lib/string.o
       lib/string.c: In function 'strlcat':
       lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
       make[2]: *** [lib/string.o] Error 1
       $
       $ grep linux/bug.h lib/string.c
       #include <linux/bug.h>
       $
 
 We've included <linux/bug.h> for the BUG infrastructure and yet we
 still get a compile fail!  [We've not kernel.h for BUILD_BUG_ON.]
 Ugh - very confusing for someone who is new to kernel development.
 
 With the above in mind, the goals of this changeset are:
 
 1) find and fix any include/*.h files that were relying on the
    implicit presence of BUG code.
 2) find and fix any C files that were consuming kernel.h and
    hence relying on implicitly getting some/all BUG code.
 3) Move the BUG related code living in kernel.h to <linux/bug.h>
 4) remove the asm/bug.h from kernel.h to finally break the chain.
 
 During development, the order was more like 3-4, build-test, 1-2.
 But to ensure that git history for bisect doesn't get needless
 build failures introduced, the commits have been reorderd to fix
 the problem areas in advance.

Supports both little and big endian. Unaligned loads are emitted

Hardware integer division is used if it is available.

Enabled in the same way as for x86-64 and PPC64:

101d9b0ded ARM: use set_current_blocked() and block_sigmask()
As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check for shared signals we're about to block.

Also, use the new helper function introduced in commit 5e6292c0f2
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures.  In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Before replacing an instruction, the ftrace code determines what the old
instruction should be and verifies that that's what's really there in
memory before replacing it.  This is useful if for example a bug in
mcountrecord causes it to record wrong locations.

However, in cases where we replace call sites in entry-common.S, these
checks are not needed.  For these, we currently just memcpy() the memory
content and then "verify" it -- this is quite useless and can be
removed.

9141a003a4 ARM: 7316/1: kexec: EOI active and mask all interrupts in kexec crash path
The kexec machine crash code can be called in interrupt context via a
sysrq trigger made using the magic key combination. If the irq chip
dealing with the serial interrupt is using the fasteoi flow handler,
then we will never EOI the interrupt because the interrupt handler will
be fatal. In the case of a GIC, this results in the crash kernel not
receiving interrupts on that CPU interface.

This patch adds code (based on the PowerPC implementation) to EOI any
pending interrupts on the crash CPU before masking and disabling all
interrupts. Secondary cores are not a problem since they are placed into
a cpu_relax() loop via an IPI.

requires nothing from asm/irq.h, as Grant says:

909af768e8 coredump: remove VM_ALWAYSDUMP flag
The motivation for this patchset was that I was looking at a way for a
qemu-kvm process, to exclude the guest memory from its core dump, which
can be quite large.  There are already a number of filter flags in
/proc/<pid>/coredump_filter, however, these allow one to specify 'types'
of kernel memory, not specific address ranges (which is needed in this
case).

Since there are no more vma flags available, the first patch eliminates
the need for the 'VM_ALWAYSDUMP' flag.  The flag is used internally by
the kernel to mark vdso and vsyscall pages.  However, it is simple
enough to check if a vma covers a vdso or vsyscall page without the need
for this flag.

The second patch then replaces the 'VM_ALWAYSDUMP' flag with a new
'VM_NODUMP' flag, which can be set by userspace using new madvise flags:
'MADV_DONTDUMP', and unset via 'MADV_DODUMP'.  The core dump filters
continue to work the same as before unless 'MADV_DONTDUMP' is set on the
region.

The qemu code which implements this features is at:

  http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch

In my testing the qemu core dump shrunk from 383MB -> 13MB with this
patch.

I also believe that the 'MADV_DONTDUMP' flag might be useful for
security sensitive apps, which might want to select which areas are
dumped.

This patch:

The VM_ALWAYSDUMP flag is currently used by the coredump code to
indicate that a vma is part of a vsyscall or vdso section.  However, we
can determine if a vma is in one these sections by checking it against
the gate_vma and checking for a non-NULL return value from
arch_vma_name().  Thus, freeing a valuable vma bit.

0b0c9d3a58 The IOMMU updates for this round are not very large patch-wise. But
they contain two new IOMMU drivers for the ARM Tegra 2 and 3 platforms.
 Besides that there are also a few patches for the AMD IOMMU which
 prepare the driver for adding intr-remapping support and a couple of
 fixes.

475c77edf8 Merge branch 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci
Pull PCI changes (including maintainer change) from Jesse Barnes:
 "This pull has some good cleanups from Bjorn and Yinghai, as well as
  some more code from Yinghai to better handle resource re-allocation
  when enabled.

  There's also a new initcall_debug feature from Arjan which will print
  out quirk timing information to help identify slow quirks for fixing
  or refinement (Yinghai sent in a few patches to do just that once the
  new debug code landed).

  Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
  He's been a core PCI and Linux contributor for some time now, and has
  kindly volunteered to take over.  I just don't feel I have the time
  for PCI review and work that it deserves lately (I've taken on some
  other projects), and haven't been as responsive lately as I'd like, so
  I approached Bjorn asking if he'd like to manage things.  He's going
  to give it a try, and I'm confident he'll do at least as well as I
  have in keeping the tree managed, patches flowing, and keeping things
  stable."

Fix up some fairly trivial conflicts due to other cleanups (mips device
resource fixup cleanups clashing with list handling cleanup, ppc iseries
removal clashing with pci_probe_only cleanup etc)

4ba7c3c3c6 ARM: OMAP3+: fix oops triggered in omap_prcm_register_chain_handler(v1)
This patch fixes the oops below[1].

Obviously, the count of "struct irq_chip_generic" instances to be
allocated and setup should be irq_setup->nr_regs instead of
irq_setup->nr_regs plus one, so just fix the iterator to avoid
the oops.

9fa2df6b90 ARM: OMAP2+: OPP: allow OPP enumeration to continue if device is not present
On platforms such as OMAP3, certain variants may not have IVA, SGX
or some specific component. We currently have a check to aid fixing
wrong population of OPP entries for issues such as typos. This however
causes a conflict with valid requirement where the SoC variant does
not actually have the module present.

So, reduce the severity of the print to a debug statement and skip
registering that specific OPP, but continue down the list.

68523f4233 ARM: OMAP4: Workaround the OCP synchronisation issue with 32K synctimer.
On OMAP4, recently a synchronisation bug is discovered by hardware
team, which leads to incorrect timer value read from 32K sync timer
IP when the IP is comming out of idle.

The issue is due to the synchronization methodology used in the SYNCTIMER IP.
The value of the counter register in 32kHz domain is synchronized to the OCP
domain register only at count up event, and if the OCP clock is switched off,
the OCP register gets out of synch until the first count up event after the
clock is switched back -at the next falling edge of the 32kHz clock.

Further investigation revealed that it applies to gptimer1 and watchdog timer2
as well which may run on 32KHz. This patch fixes the issue for all the
applicable modules.

The BUG has not made it yet to the OMAP errata list and it is applicable to
OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps.

By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU
is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces
the OCP clock to be running and allow the counter value to be updated properly
in the OCP clock domain.

The bug is going to fixed in future OMAP versions.

b2094ef840 Updates of sound stuff for 3.4-rc1
Here is the first big update chunk of sound stuff for 3.4-rc1.
 
 In the common sound infrastructure, there are a few changes for
 dynamic PCM support (used in ASoC) and a few clean-ups.  Majority of
 changes are found, as usual, in HD-audio and ASoC.
 
 Some highlights of HD-audio changes:
 - All the long-standing static quirk codes for Realtek codec were
 finally removed by fixing and extending the Realtek auto-parser.
 
 - The mute-LED control is standardized over all HD-audio codec
   drivers using the extended vmaster hook.
 
 - The vmaster slave mixer elements are initialized to 0dB as default
   so that the user won't be annoyed by the silent output after
   updates, e.g. due to the additions of new elements.
 
 - Other many fix-ups for the misc HD-audio devices.
 
 In the ASoC side, this is a very active release, including a quite a
 few framework enhancements.  Some highlights:
 
 - Support for widgets not associated with a CODEC, an important part
   of the dynamic PCM framework.
 
 - A library factoring out the common code shared by dmaengine based
   DMA drivers contributed by Lars-Peter Clausen.  This will save a lot
   of code and make it much easier to deploy enhancements to
   dmaengine.
 
 - Support for binary controls, used for providing runtime
   configuration of algorithm coefficients.
 
 - A new DAPM widget type for regulator supplies allowing drivers for
   devices that can power down unused supplies while active to do
   without any per-driver code.
 
 - DAPM widgets for DAIs, initially giving a speed boost for playback
   startup and shutdown and also the basis for CODEC<->CODEC DAI link
   support.
 
 - Support for specifying the number of significant bits on audio
   interfaces, useful for allowing applications to know how much effort
   to put into generating data for a larger sample format.
 
 - Conversion of the FSI driver used on some SH processors to
   DMAEngine.
 
 - Conversion of EP93xx drivers to DMAEngine.
 
 - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
   WM2200.
 
 - Move audmux driver from arc/arm to sound/soc
 
 - McBSP move from arch/ to sound/ and updates
 
 Also, a few small updates and fixes for other drivers like au88x0,
 ymfpci, USB 6fire, USB usx2yaudio are included.

c207f3a431 Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
 from Linux IRQ numbers to hardware irq numbering), generalizes it,
 renames it to irq_domain, and makes it available to all architectures.
 
 Originally the plan has been to create an all-new irq_domain
 implementation which addresses some of the powerpc shortcomings such
 as not handling 1:1 mappings well, but doing that proved to be far
 more difficult and invasive than generalizing the working code and
 refactoring it in-place.  So, this branch rips out the 'new'
 irq_domain and replaces it with the modified powerpc version (in a
 fully bisectable way of course).  It converts all users over to the
 new API and makes irq_domain selectable on any architecture.
 
 No architecture is forced to enable irq_domain, but the infrastructure
 is required for doing OpenFirmware style irq translations.  It will
 even work on SPARC even though SPARC has it's own mechanism for
 translating irqs at boot time.  MIPS, microblaze, embedded x86 and c6x
 are converted too.
 
 The resulting irq_domain code is probably still too verbose and can be
 optimized more, but that can be done incrementally and is a task for
 follow-on patches.

  as not handling 1:1 mappings well, but doing that proved to be far
  more difficult and invasive than generalizing the working code and
  refactoring it in-place.  So, this branch rips out the 'new'
  irq_domain and replaces it with the modified powerpc version (in a
  fully bisectable way of course).  It converts all users over to the
  new API and makes irq_domain selectable on any architecture.

  No architecture is forced to enable irq_domain, but the infrastructure
  is required for doing OpenFirmware style irq translations.  It will
  even work on SPARC even though SPARC has it's own mechanism for
  translating irqs at boot time.  MIPS, microblaze, embedded x86 and c6x
  are converted too.

  The resulting irq_domain code is probably still too verbose and can be
  optimized more, but that can be done incrementally and is a task for
  follow-on patches."

beeaa103ee dmaengine: at_hdmac: add slave config operation
This patch introduces DMA_SLAVE_CONFIG to at_hdmac Atmel DMA driver.

It is needed to fix a regression in the use of atmel-mci.c driver on Atmel
AT91 platforms brouth by e2b35f3:
"dmaengine/dw_dmac: Fix dw_dmac user drivers to adapt to slave_config changes"

We remove some parts of the private structure "at_dma_slave" and use the
information provided by "struct dma_slave_config": source/destination
peripheral registers and access width.

AT_DMA_SLAVE_WIDTH_* values used previously are not needed anymore as we
now use the standard ones. Although some conversion functions are needed to
match register expected values.

Some AT91 sub-architecture specific files are slightly touched by this patch
but it cannot be split because it can break compilation.

8f9c60f2e2 fbdev: sh_mipi_dsi: add extra phyctrl for sh_mipi_dsi_info
sh_mipi uses some clocks, but the method of setup depends on CPU.

Current SuperH (like sh73a0) can control all of these clocks
by CPG (Clock Pulse Generator).
It means we can control it by clock framework only.
But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS,
and only sh7372 has PHYCTRL::PLLDS.

But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was
overwrote since the callback timing of clock setting was changed
by c2658b70f0
(fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()).
To solve this issue, this patch adds extra .phyctrl.

This patch adds detail explanation for unclear mipi settings
and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

9c2b957db1 Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf events changes for v3.4 from Ingo Molnar:

 - New "hardware based branch profiling" feature both on the kernel and
   the tooling side, on CPUs that support it.  (modern x86 Intel CPUs
   with the 'LBR' hardware feature currently.)

   This new feature is basically a sophisticated 'magnifying glass' for
   branch execution - something that is pretty difficult to extract from
   regular, function histogram centric profiles.

   The simplest mode is activated via 'perf record -b', and the result
   looks like this in perf report:

	$ perf record -b any_call,u -e cycles:u branchy

	$ perf report -b --sort=symbol
	    52.34%  [.] main                   [.] f1
	    24.04%  [.] f1                     [.] f3
	    23.60%  [.] f1                     [.] f2
	     0.01%  [k] _IO_new_file_xsputn    [k] _IO_file_overflow
	     0.01%  [k] _IO_vfprintf_internal  [k] _IO_new_file_xsputn
	     0.01%  [k] _IO_vfprintf_internal  [k] strchrnul
	     0.01%  [k] __printf               [k] _IO_vfprintf_internal
	     0.01%  [k] main                   [k] __printf

   This output shows from/to branch columns and shows the highest
   percentage (from,to) jump combinations - i.e.  the most likely taken
   branches in the system.  "branches" can also include function calls
   and any other synchronous and asynchronous transitions of the
   instruction pointer that are not 'next instruction' - such as system
   calls, traps, interrupts, etc.

   This feature comes with (hopefully intuitive) flat ascii and TUI
   support in perf report.

 - Various 'perf annotate' visual improvements for us assembly junkies.
   It will now recognize function calls in the TUI and by hitting enter
   you can follow the call (recursively) and back, amongst other
   improvements.

 - Multiple threads/processes recording support in perf record, perf
   stat, perf top - which is activated via a comma-list of PIDs:

	perf top -p 21483,21485
	perf stat -p 21483,21485 -ddd
	perf record -p 21483,21485

 - Support for per UID views, via the --uid paramter to perf top, perf
   report, etc.  For example 'perf top --uid mingo' will only show the
   tasks that I am running, excluding other users, root, etc.

 - Jump label restructurings and improvements - this includes the
   factoring out of the (hopefully much clearer) include/linux/static_key.h
   generic facility:

	struct static_key key = STATIC_KEY_INIT_FALSE;

	...

	if (static_key_false(&key))
	        do unlikely code
	else
	        do likely code

	...
	static_key_slow_inc();
	...
	static_key_slow_inc();
	...

   The static_key_false() branch will be generated into the code with as
   little impact to the likely code path as possible.  the
   static_key_slow_*() APIs flip the branch via live kernel code patching.

   This facility can now be used more widely within the kernel to
   micro-optimize hot branches whose likelihood matches the static-key
   usage and fast/slow cost patterns.

 - SW function tracer improvements: perf support and filtering support.

 - Various hardenings of the perf.data ABI, to make older perf.data's
   smoother on newer tool versions, to make new features integrate more
   smoothly, to support cross-endian recording/analyzing workflows
   better, etc.

 - Restructuring of the kprobes code, the splitting out of 'optprobes',
   and a corner case bugfix.

 - Allow the tracing of kernel console output (printk).

 - Improvements/fixes to user-space RDPMC support, allowing user-space
   self-profiling code to extract PMU counts without performing any
   system calls, while playing nice with the kernel side.

 - 'perf bench' improvements

 - ... and lots of internal restructurings, cleanups and fixes that made
   these features possible.  And, as usual this list is incomplete as
   there were also lots of other improvements

489e7bece7 Merge branch 'fixes' into next/fixes-non-critical
The one fix didn't make the cut for 3.3, so we're putting it
into v3.4. Tony tells me "There are more patches needed to make
multiple smsc91x instances work, but we need to hear from people
with such boards first. Then those can be tagged for stable.",
so we don't mark this patch stable yet.

e8a30b251b ARM: OMAP2+: Remove __init from DSI mux functions
Commit d1589f0912 (ARM: OMAP2+: Mark
omap_hsmmc_init and omap_mux related functions as __init) changed DSI
muxing functions to __init. This doesn't work, as the muxing functions
are used every time a DSI display is enabled or disabled.

This patch removes the __inits from DSI mux functions that were
accidentally marked as __init, and makes omap4_hdmi_mux_pads __init
like it should be.
