50bdd430c2 res_counter: return amount of charges after res_counter_uncharge() 
It is useful to know how many charges are still left after a call to
res_counter_uncharge.  While it is possible to issue a res_counter_read
after uncharge, this can be racy.

If we need, for instance, to take some action when the counters drop down
to 0, only one of the callers should see it.  This is the same semantics
as the atomic variables in the kernel.

Since the current return value is void, we don't need to worry about
anything breaking due to this change: nobody relied on that, and only
users appearing from now on will be checking this value.

c450ba0fc1 aoe: allow user to disable target failure timeout 
With this change, the aoe driver treats the value zero as special for
the aoe_deadsecs module parameter.  Normally, this value specifies the
number of seconds during which the driver will continue to attempt
retransmits to an unresponsive AoE target.  After aoe_deadsecs has
elapsed, the aoe driver marks the aoe device as "down" and fails all
I/O.

The new meaning of an aoe_deadsecs of zero is for the driver to
retransmit commands indefinitely.

2f4b3bf6b2 /proc/pid/status: add "Seccomp" field 
It is currently impossible to examine the state of seccomp for a given
process.  While attaching with gdb and attempting "call
prctl(PR_GET_SECCOMP,...)" will work with some situations, it is not
reliable.  If the process is in seccomp mode 1, this query will kill the
process (prctl not allowed), if the process is in mode 2 with prctl not
allowed, it will similarly be killed, and in weird cases, if prctl is
filtered to return errno 0, it can look like seccomp is disabled.

When reviewing the state of running processes, there should be a way to
externally examine the seccomp mode.  ("Did this build of Chrome end up
using seccomp?" "Did my distro ship ssh with seccomp enabled?")

This adds the "Seccomp" line to /proc/$pid/status.

834f82e2aa procfs: add VmFlags field in smaps output 
During c/r sessions we've found that there is no way at the moment to
fetch some VMA associated flags, such as mlock() and madvise().

This leads us to a problem -- we don't know if we should call for mlock()
and/or madvise() after restore on the vma area we're bringing back to
life.

This patch intorduces a new field into "smaps" output called VmFlags,
where all set flags associated with the particular VMA is shown as two
letter mnemonics.

[ Strictly speaking for c/r we only need mlock/madvise bits but it has been
  said that providing just a few flags looks somehow inconsistent.  So all
  flags are here now. ]

This feature is made available on CONFIG_CHECKPOINT_RESTORE=n kernels, as
other applications may start to use these fields.

The data is encoded in a somewhat awkward two letters mnemonic form, to
encourage userspace to be prepared for fields being added or removed in
the future.

58156c8fbf fat: provide option for setting timezone offset 
So far FAT either offsets time stamps by sys_tz.minuteswest or leaves them
as they are (when tz=UTC mount option is used).  However in some cases it
is useful if one can specify time stamp offset on his own (e.g.  when time
zone of the camera connected is different from time zone of the computer,
or when HW clock is in UTC and thus sys_tz.minuteswest == 0).

So provide a mount option time_offset= which allows user to specify offset
in minutes that should be applied to time stamps on the filesystem.

akpm: this code would work incorrectly when used via `mount -o remount',
because cached inodes would not be updated.  But fatfs's fat_remount() is
basically a no-op anyway.

8cc9764c9c drivers/video/backlight/lp855x_bl.c: use generic PWM functions 
The LP855x family devices support the PWM input for the backlight control.
 Period of the PWM is configurable in the platform side.  Platform
specific functions are unnecessary anymore because generic PWM functions
are used inside the driver.

(PWM input mode)
To set the brightness, new lp855x_pwm_ctrl() is used.
If a PWM device is not allocated, devm_pwm_get() is called.
The PWM consumer name is from the chip name such as 'lp8550' and 'lp8556'.
To get the brightness value, no additional handling is required.
Just the value of 'props.brightness' is returned.

If the PWM driver is not ready while initializing the LP855x driver, it's
OK.  The PWM device can be retrieved later, when the brightness value is
changed.

Documentation is updated with an example.

 - Nano River's viperboard
 - TI's TPS80031, AM335x TS/ADC,
 - Realtek's MMC/memstick card reader
 - Nokia's retu
 
 We also got some notable cleanups and improvements:
 
 - tps6586x got converted to IRQ domains.
 - tps65910 and tps65090 moved to the regmap IRQ API.
 - STMPE is now Device Tree aware.
 - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ

36cd5c19c3 There are two major features for this merge window. The first is 
inline data, which allows small files or directories to be stored in
 the in-inode extended attribute area.  (This requires that the file
 system use inodes which are at least 256 bytes or larger; 128 byte
 inodes do not have any room for in-inode xattrs.)
 
 The second new feature is SEEK_HOLE/SEEK_DATA support.  This is
 enabled by the extent status tree patches, and this infrastructure
 will be used to further optimize ext4 in the future.
 
 Beyond that, we have the usual collection of code cleanups and bug
 fixes.

Merge tag 'balancenuma-v11' of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma

Pull Automatic NUMA Balancing bare-bones from Mel Gorman:
 "There are three implementations for NUMA balancing, this tree
  (balancenuma), numacore which has been developed in tip/master and
  autonuma which is in aa.git.

  In almost all respects balancenuma is the dumbest of the three because
  its main impact is on the VM side with no attempt to be smart about
  scheduling.  In the interest of getting the ball rolling, it would be
  desirable to see this much merged for 3.8 with the view to building
  scheduler smarts on top and adapting the VM where required for 3.9.

  The most recent set of comparisons available from different people are

    mel:    https://lkml.org/lkml/2012/12/9/108
    mingo:  https://lkml.org/lkml/2012/12/7/331
    tglx:   https://lkml.org/lkml/2012/12/10/437
    srikar: https://lkml.org/lkml/2012/12/10/397

  The results are a mixed bag.  In my own tests, balancenuma does
  reasonably well.  It's dumb as rocks and does not regress against
  mainline.  On the other hand, Ingo's tests shows that balancenuma is
  incapable of converging for this workloads driven by perf which is bad
  but is potentially explained by the lack of scheduler smarts.  Thomas'
  results show balancenuma improves on mainline but falls far short of
  numacore or autonuma.  Srikar's results indicate we all suffer on a
  large machine with imbalanced node sizes.

  My own testing showed that recent numacore results have improved
  dramatically, particularly in the last week but not universally.
  We've butted heads heavily on system CPU usage and high levels of
  migration even when it shows that overall performance is better.
  There are also cases where it regresses.  Of interest is that for
  specjbb in some configurations it will regress for lower numbers of
  warehouses and show gains for higher numbers which is not reported by
  the tool by default and sometimes missed in treports.  Recently I
  reported for numacore that the JVM was crashing with
  NullPointerExceptions but currently it's unclear what the source of
  this problem is.  Initially I thought it was in how numacore batch
  handles PTEs but I'm no longer think this is the case.  It's possible
  numacore is just able to trigger it due to higher rates of migration.

  These reports were quite late in the cycle so I/we would like to start
  with this tree as it contains much of the code we can agree on and has
  not changed significantly over the last 2-3 weeks."

While the mapping between I2C adapter functionality flags and

Also drop the reference to 2 command byte I2C block reads, there is no

This is the second batch of SoC updates for the 3.8 merge window,
 containing parts that had dependencies on earlier branches such that we
 couldn't include them with the first branch.
 
 These are general updates for Samsung Exynos, Renesas/shmobile and a
 topic branch that adds SMP support to Altera's socfpga platform.

Pull x86 ACPI update from Peter Anvin:
 "This is a patchset which didn't make the last merge window.  It adds a
  debugging capability to feed ACPI tables via the initramfs.

  On a grander scope, it formalizes using the initramfs protocol for
  feeding arbitrary blobs which need to be accessed early to the kernel:
  they are fed first in the initramfs blob (lots of bootloaders can
  concatenate this at boot time, others can use a single file) in an
  uncompressed cpio archive using filenames starting with "kernel/".

  The ACPI maintainers requested that this patchset be fed via the x86
  tree rather than the ACPI tree as the footprint in the general x86
  code is much bigger than in the ACPI code proper."

f6e858a00a Merge branch 'akpm' (Andrew's patch-bomb) 
Merge misc VM changes from Andrew Morton:
 "The rest of most-of-MM.  The other MM bits await a slab merge.

  This patch includes the addition of a huge zero_page.  Not a
  performance boost but it an save large amounts of physical memory in
  some situations.

  Also a bunch of Fujitsu engineers are working on memory hotplug.
  Which, as it turns out, was badly broken.  About half of their patches
  are included here; the remainder are 3.8 material."

However, this merge disables CONFIG_MOVABLE_NODE, which was totally
broken.  We don't add new features with "default y", nor do we add
Kconfig questions that are incomprehensible to most people without any
help text.  Does the feature even make sense without compaction or
memory hotplug?

b8edf848e9 ARM: arm-soc: multiplatform conversion patches 
Here are more patches in the progression towards multiplatform, sparse
 irq conversions in particular.
 
 Tegra has a handful of cleanups and general groundwork, but is
 not quite there yet on full enablement.
 
 Platforms that are enabled through this branch are VT8500 and Zynq. note
 that i.MX was converted in one of the earlier cleanup branches as
 well (before we started a separate topic for multiplatform). And both
 new platforms for this merge window, sunxi and bcm, were merged with
 multiplatform support enabled.

db5b0ae007 ARM: arm-soc: device tree conversions and enablement 
Continued device tree conversion and enablement across a number of
 platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
 smaller series as well.
 
 ux500 has seen continued conversion for platforms. Several platforms have
 seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
 is adding data for new devices/drivers, and Exynos has a bunch of new
 bindings and devices added as well.
 
 So, pretty much the same progression in the right direction as the last
 few releases.
