46c77e2bb0 tools/vm/page-types.c: support KPF_SOFTDIRTY bit 
Soft dirty bit allows us to track which pages are written since the last
clear_ref (by "echo 4 > /proc/pid/clear_refs".) This is useful for
userspace applications to know their memory footprints.

Note that the kernel exposes this flag via bit[55] of /proc/pid/pagemap,
and the semantics is not a default one (scheduled to be the default in the
near future.) However, it shifts to the new semantics at the first
clear_ref, and the users of soft dirty bit always do it before utilizing
the bit, so that's not a big deal.  Users must avoid relying on the bit in
page-types before the first clear_ref.

85b35feaec mm/sparsemem: use PAGES_PER_SECTION to remove redundant nr_pages parameter 
For below functions,

- sparse_add_one_section()
- kmalloc_section_memmap()
- __kmalloc_section_memmap()
- __kfree_section_memmap()

they are always invoked to operate on one memory section, so it is
redundant to always pass a nr_pages parameter, which is the page numbers
in one section.  So we can directly use predefined macro PAGES_PER_SECTION
instead of passing the parameter.

948927ee9e mm, mempolicy: make mpol_to_str robust and always succeed 
mpol_to_str() should not fail.  Currently, it either fails because the
string buffer is too small or because a string hasn't been defined for a
mempolicy mode.

If a new mempolicy mode is introduced and no string is defined for it,
just warn and return "unknown".

If the buffer is too small, just truncate the string and return, the
same behavior as snprintf().

This also fixes a bug where there was no NULL-byte termination when doing
*p++ = '=' and *p++ ':' and maxlen has been reached.

01b0f19707 cpu/mem hotplug: add try_online_node() for cpu_up() 
cpu_up() has #ifdef CONFIG_MEMORY_HOTPLUG code blocks, which call
mem_online_node() to put its node online if offlined and then call
build_all_zonelists() to initialize the zone list.

These steps are specific to memory hotplug, and should be managed in
mm/memory_hotplug.c.  lock_memory_hotplug() should also be held for the
whole steps.

For this reason, this patch replaces mem_online_node() with
try_online_node(), which performs the whole steps with
lock_memory_hotplug() held.  try_online_node() is named after
try_offline_node() as they have similar purpose.

There is no functional change in this patch.

- Merged the GPIO descriptor API from Alexandre Courbot.
   This is a first step toward trying to get rid of the
   global GPIO numberspace for the future.
 
 - Add an API so that driver can flag that a certain GPIO
   line is being used by a irqchip backend for generating
   IRQs, so that we can enforce checks, like not allowing
   users to switch that line to an output at runtime, since
   this makes no sense. Implemented corresponding calls
   in a few select drivers.
 
 - ACPI GPIO cleanups, refactorings and switch to using the
   descriptor-based interface.
 
 - Support for the TPS80036 Palmas GPIO variant.
 
 - A new driver for the Broadcom Kona GPIO SoC IP block.
 
 - Device tree support for the PCF857x driver.
 
 - A set of ARM GPIO refactorings with the goal of getting
   rid of a bunch of custom GPIO implementations from the
   arch/arm/* tree:
 
   - Move the IOP GPIO driver to the GPIO subsystem and
     fix all users to use the gpiolib API for accessing
     GPIOs. Delete the old custom GPIO implementation.
 
   - Delete the unused custom PXA GPIO implemention.
 
   - Convert all users of the IXP4 custom GPIO
     implementation to use gpiolib and delete the custom

   - Delete the custom Gemini GPIO implementation, also
     completely unused.
 
 - Various cleanups and renamings.

Merge tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO changes from Linus Walleij:
 "Here is the bulk of GPIO changes for the v3.13 development cycle.

  I've got ACKs for the things that affect other subsystems (or it's my
  own subsystem, like pinctrl).  Most of that pertain to an attempt from
  my side to consolidate and get rid of custom GPIO implementations in
  the ARM tree.  I will continue doing this.

  The main change this time is the new GPIO descriptor API, background
  for this can be found in Corbet's summary from this january in LWN:

    http://lwn.net/Articles/533632/

  Summary:

   - Merged the GPIO descriptor API from Alexandre Courbot.  This is a
     first step toward trying to get rid of the global GPIO numberspace

   - Add an API so that driver can flag that a certain GPIO line is

     enforce checks, like not allowing users to switch that line to an

eeab517b68 sound updates for 3.13-rc1 
There are no too intrusive changes in this update batch.  The biggest
 LOC is found in the new DICE driver, and other small changes are
 scattered over the whole sound subtree (which is a common pattern).
 
 Below are highlights:
 
 - ALSA core:
   * Memory allocation support with genpool
   * Fix blocking in drain ioctl of compress_offload
 
 - HD-audio:
   * Improved AMD HDMI supports
   * Intel HDMI detection improvements
   * thinkpad_acpi mute-key integration
   * New PCI ID, New ALC255,285,293 codecs, CX20952
 
 - USB-audio:
   * New buffer size management
   * Clean up endpoint handling codes
 
 - ASoC:
   * Further work on the dmaengine helpers, including support for
     configuring the parameters for DMA by reading the capabilities of
     the DMA controller which removes some guesswork and magic numbers
     from drivers.
   * A refresh of the documentation.
   * Conversions of many drivers to direct regmap API usage in order to
     allow the ASoC level register I/O code to be removed, this will
     hopefully be completed by v3.14.
   * Support for using async register I/O in DAPM, reducing the time

Pull sound updates from Takashi Iwai:
 "There are no too intrusive changes in this update batch.  The biggest
  LOC is found in the new DICE driver, and other small changes are
  scattered over the whole sound subtree (which is a common pattern).

  Below are highlights:

   - ALSA core:
     * Memory allocation support with genpool
     * Fix blocking in drain ioctl of compress_offload

   - HD-audio:
     * Improved AMD HDMI supports
     * Intel HDMI detection improvements
     * thinkpad_acpi mute-key integration
     * New PCI ID, New ALC255,285,293 codecs, CX20952

   - USB-audio:
     * New buffer size management
     * Clean up endpoint handling codes

   - ASoC:
     * Further work on the dmaengine helpers, including support for
       configuring the parameters for DMA by reading the capabilities of
       the DMA controller which removes some guesswork and magic numbers
       from drivers.
     * A refresh of the documentation.
     * Conversions of many drivers to direct regmap API usage in order
       to allow the ASoC level register I/O code to be removed, this
       will hopefully be completed by v3.14.
     * Support for using async register I/O in DAPM, reducing the time
       taken to implement power transitions on systems that support it.

f095ca6b31 spi: Updates for v3.13 
As well as the usual driver updates and cleanups there's a few
 improvements to the core here:
 
  - The start of some improvements to factor out more of the SPI message
    loop into the core.  Right now this is just simplifying the code a
    bit but hopefully next time around we'll also have managed to roll
    out some noticable performance improvements which drivers can take
    advantage of.
  - Support for loading modules for ACPI enumerated SPI devices.
  - Managed registration for SPI controllers.
  - Helper for another common I/O pattern.

c6d65bf246 regulator: Updates for v3.13 
Lots of driver updates here plus some nice new core features, the main
 one being the first:
 
  - Enable support for providing a dummy regulator when we know that one
    must exist for the device to be functional.  This makes it much
    easier to add regulator support to drivers since we don't require
    that the machine integration for all systems using the device be
    updated to provide regulators.
  - Substantial reduction in the amount of busy waiting done while
    waiting for enables to complete.
  - Allow MFDs to distribute regulator supplies to child devices so we
    don't have to expose the internal structure of MFDs outside of the
    driver.
  - Managed registeration for regulators.

4fc9ed3344 regmap: Updates for v3.13 
The main thing this time around has been some improvments to async I/O.
 
  - Cleaned up the async I/O support and extended it to allow single
    register writes more easily.  This is now used where possible for
    internally generated I/O, providing performance improvements for
    devices that can do async I/O.
  - An API for issuing a sequence of register writes as a single
    operation.  Some devices and buses can take advantage of this to
    do the I/O faster.
  - Addition of regmap_field APIs which help drivers for devices with
    repeated IPs or which move registers around between revisions to
    share helpers.
  - Support for SPMI buses.

Pull perf updates from Ingo Molnar:
 "As a first remark I'd like to note that the way to build perf tooling
  has been simplified and sped up, in the future it should be enough for
  you to build perf via:

        cd tools/perf/
        make install

  (ie without the -j option.) The build system will figure out the
  number of CPUs and will do a parallel build+install.

  The various build system inefficiencies and breakages Linus reported
  against the v3.12 pull request should now be resolved - please
  (re-)report any remaining annoyances or bugs.

  Main changes on the perf kernel side:

   * Performance optimizations:

      . x86 Intel PEBS processing speedups,           by Peter Zijlstra

   * Enhanced hardware support:
      . for Intel Ivy Bridge-EP uncore PMUs,          by Zheng Yan
      . for Haswell transactions,                     by Andi Kleen, Peter Zijlstra

   * Core perf events code enhancements and fixes by Oleg Nesterov:
      . for uprobes, if fork() is called with pending ret-probes
      . for uprobes platform support code

   * New ABI details by Andi Kleen:
      . Report x86 Haswell TSX transaction abort cost as weight

  Main changes on the perf tooling side (some of these tooling changes
  utilize the above kernel side changes):

   * 'perf report/top' enhancements:

      . Convert callchain children list to rbtree, greatly reducing the
        time taken for callchain processing, from Namhyung Kim.

      . Add new COMM infrastructure, further improving histogram
        processing, from Frédéric Weisbecker, one fix from Namhyung Kim.

      . Add /proc/kcore based live-annotation improvements, including
        build-id cache support, multi map 'call' instruction navigation
        fixes, kcore address validation, objdump workarounds.  From
        Adrian Hunter.

      . Show progress on histogram collapsing, that can take a long
        time, from Namhyung Kim.

      . Add --max-stack option to limit callchain stack scan in 'top'

        stack depth is an option, from Waiman Long.

      . Add new option --ignore-vmlinux for perf top, from Willy
        Tarreau.

   * 'perf trace' enhancements:

      . 'perf trace' now can can use a 'perf probe' dynamic tracepoints
        to hook into the userspace -> kernel pathname copy so that it
        can map fds to pathnames without reading /proc/pid/fd/ symlinks.
        From Arnaldo Carvalho de Melo.

      . Show VFS path associated with fd in live sessions, using a
        'vfs_getname' 'perf probe' created dynamic tracepoint or by
        looking at /proc/pid/fd, from Arnaldo Carvalho de Melo.

      . Add 'trace' beautifiers for lots of syscall arguments, from
        Arnaldo Carvalho de Melo.

      . Implement more compact 'trace' output by suppressing zeroed
        args, from Arnaldo Carvalho de Melo.

      . Improve error messages in 'trace', providing hints about system
        configuration steps needed for using it, from Ramkumar
        Ramachandra.

      . 'perf trace' now emits hints as to why tracing is not possible,
        helping the user to setup the system to allow tracing in the
        desired permission granularity, telling if the problem is due to
        debugfs not being mounted or with not enough permission for
        !root, /proc/sys/kernel/perf_event_paranoit value, etc.  From
        Arnaldo Carvalho de Melo.

   * 'perf record' enhancements:

      . Check maximum frequency rate for record/top, emitting better
        error messages, from Jiri Olsa.

      . 'perf record' code cleanups, from David Ahern.

      . Improve write_output error message in 'perf record', from Adrian
        Hunter.

      . Allow specifying B/K/M/G unit to the --mmap-pages arguments,
        from Jiri Olsa.

      . Fix command line callchain attribute tests to handle the new
        -g/--call-chain semantics, from Arnaldo Carvalho de Melo.

   * 'perf kvm' enhancements:

      . Disable live kvm command if timerfd is not supported, from David
        Ahern.

      . Fix detection of non-core features, from David Ahern.

      . Add usage to 'perf list', from David Ahern.

      . Show error in 'perf list' if tracepoints not available, from
        Pekka Enberg.

   * 'perf probe' enhancements:

      . Support "$vars" meta argument syntax for local variables,
        allowing asking for all possible variables at a given probe
        point to be collected when it hits, from Masami Hiramatsu.

   * 'perf sched' enhancements:

      . Address the root cause of that 'perf sched' stack initialization
        build slowdown, by programmatically setting a big array after
        moving the global variable back to the stack.  Fix from Adrian
        Hunter.

   * 'perf script' enhancements:

      . Set up output options for in-stream attributes, from Adrian
        Hunter.

      . Print addr by default for BTS in 'perf script', from Adrian
        Juntmer

   * 'perf stat' enhancements:

      . Improved messages when doing profiling in all or a subset of
        CPUs using a workload as the session delimitator, as in:

         'perf stat --cpu 0,2 sleep 10s'

        from Arnaldo Carvalho de Melo.

      . Add units to nanosec-based counters in 'perf stat', from David
        Ahern.

      . Remove bogus info when using 'perf stat' -e cycles/instructions,
        from Ramkumar Ramachandra.

   * 'perf lock' enhancements:

      . 'perf lock' fixes and cleanups, from Davidlohr Bueso.

   * 'perf test' enhancements:

      . Fixup PERF_SAMPLE_TRANSACTION handling in sample synthesizing
        and 'perf test', from Adrian Hunter.

      . Clarify the "sample parsing" test entry, from Arnaldo Carvalho
        de Melo.

      . Consider PERF_SAMPLE_TRANSACTION in the "sample parsing" test,
        from Arnaldo Carvalho de Melo.

      . Memory leak fixes in 'perf test', from Felipe Pena.

   * 'perf bench' enhancements:

   * Generic perf tooling infrastructure/plumbing changes:

      . Separating data file properties from session, code
        reorganization from Jiri Olsa.

      . Fix version when building out of tree, as when using one of
        these:

        $ make help | grep perf

f9efbce633 ARM: SoC DT updates for 3.13 
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

53575aa99d ARM: driver updates for 3.13 
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree. In this case it's involved:
 
 - Some Davinci driver updates that has required corresponding platform code
   changes (gpio mostly)
 - CCI bindings and a few driver updates
 - Marvell mvebu patches for PCI MSI support (could have gone through the PCI
   tree for this release, but they were acked by Bjorn for 3.12 so we kept them
   through arm-soc).
 - Marvell dove switch-over to DT-based PCIe configuration
 - Misc updates for Samsung platform dmaengine drivers

 - More support for the AM33xx platforms from TI
 - Tegra 124 support, and some updates to older tegra families as well
 - imx cleanups and updates across the board
 - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,

 - A whole bunch of updates and fixes for integrator, making the platform code
   more modern and switches over to DT-only booting.
 - Support for two new Renesas shmobile chipsets. Next up for them is more work
   on consolidation instead of introduction of new non-multiplatform SoCs, we're
   all looking forward to that!
 - Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

21604cdcdc ARM: SoC cleanups for 3.13 
This branch contains code cleanups, moves and removals for 3.13.
 
 Qualcomm msm targets had a bunch of code removal for legacy non-DT
 platforms. Nomadik saw more device tree conversions and cleanup of old
 code. Tegra has some code refactoring, etc.
 
 One longish patch series from Sebastian Hasselbarth changes the init_time
 hooks and tries to use a generic implementation for most platforms,
 since they were all doing more or less the same things.
 
 Finally the "shark" platform is removed in this release. It's been
 abandoned for a while and nobody seems to care enough to keep it
 around. If someone comes along and wants to resurrect it, the removal
 can easily be reverted and code brought back.
 
 Beyond this, mostly a bunch of removals of stale content across the
 board, etc.

8b5baa460b The main feature of interest this time is quota updates. There are 
some clean ups and some patches to use the new generic lru list
 code. There is still plenty of scope for some further changes in
 due course - faster lookups of quota structures is very much
 on the todo list. Also, a start has been made towards the more tricky
 issue of using the generic lru code with glocks, but that will
 have to be completed in a subsequent merge window.
 
 The other, more minor feature, is that there have been a number of
 performance patches which relate to block allocation. In particular
 they will improve performance when the disk is nearly full.

3b098eb486 ALSA: include/uapi/sound/firewire.h: use "_UAPI" instead of "UAPI" 
When installing, "scripts/headers_install.sh" will strip guard macro'
"_UAPI" to prevent from appearing it to users. And also, all another
files which need uapi prefix always use "_UAPI", not "UAPI".

So use "_UAPI" instead of "UAPI" on the guard macro, and also give a
comment for "#endif".

f44f2a5417 ALSA: compress: fix drain calls blocking other compress functions (v6) 
The drain and drain_notify callback were blocked by low level driver
until the draining was complete. Due to this being invoked with big
fat mutex held, others ops like reading timestamp, calling pause, drop
were blocked.

So to fix this we add a new snd_compr_drain_notify() API. This would
be required to be invoked by low level driver when drain or partial
drain has been completed by the DSP. Thus we make the drain and
partial_drain callback as non blocking and driver returns immediately
after notifying DSP.  The waiting is done while releasing the lock so
that other ops can go ahead.

[ The commit 917f4b5cba was wrongly applied from the preliminary
  patch.  This commit corrects to the final version.
  Sorry for inconvenience!  -- tiwai ]
