218e149613 i2c: exynos5: add support for HSI2C on Exynos5260 SoC
HSI2C module on Exynos5260 differs from current modules in
following ways:
1.  HSI2C on Exynos5260 has fifo_depth of 16bytes
2.  Module needs to be reset as a part of init sequence.

Hence, Following changes are involved.
1. Add a new compatible string and Updates the Documentation dt bindings.
2. Introduce a variant struct to support the changes in H/W
3. Reset the module during init. Thus, bringing the module back
to default state irrespective of what firmware did with it.

9219982bc6 i2c: nomadik: Fixup system suspend
For !CONFIG_PM_RUNTIME, the device were never put back into active
state while resuming.

For CONFIG_PM_RUNTIME, we blindly trusted the device to be inactive
while we were about to handle it at suspend late, which is just too
optimistic.

Even if the driver uses pm_runtime_put_sync() after each tranfer to
return it's runtime PM resources, there are no guarantees this will
actually mean the device will inactivated. The reason is that the PM
core will prevent runtime suspend during system suspend, and thus when
a transfer occurs during the early phases of system suspend the device
will be kept active after the transfer.

To handle both issues above, use pm_runtime_force_suspend|resume() from
the system suspend|resume callbacks.

8e8782c715 i2c: imx: add SMBus block read support
The smbus block read is not currently supported for imx i2c devices.
This patchset adds the support to imx i2c bus so that blocks of data
can be read using SMbus block reads.(using i2c_smbus_read_block_data()
function from the i2c_core.c.). Tested with 3.10.9 kernel.

Pull two powerpc fixes from Ben Herrenschmidt:
 "Here are a couple of fixes for 3.15.  One from Anton fixes a nasty
  regression I introduced when trying to fix a loss of irq_work whose
  consequences is that we can completely lose timer interrupts on a
  CPU... not pretty.

  The other one is a change to our PCIe reset hook to use a firmware
  call instead of direct config space accesses to trigger a fundamental
  reset on the root port.  This is necessary so that the FW gets a
  chance to disable the link down error monitoring, which would
  otherwise trip and cause subsequent fatal EEH error"

b2e3432af1 spi: Fixes for v3.15
A few core fixes around outlying cases here, nothing that should affect
 most users but useful fixes.  The diffstat is rather larger than one
 might hope due some simple code motion in the fix for !CONFIG_DMA, the
 actual meaningful change is much smaller.
 
  - Fix handling of unsupported dual and quad mode support on slave
    registration so that drivers that can degrade gracefully do so,
    preventing regressions for drivers this is added.
  - Fix build in !CONFIG_DMA cases following addition of generic DMA
    mapping support.
  - Fix error handling for queue creation which due to wider kernel
    changes can be triggered more easily.
  - A couple of driver specific fixes.

 "Three more patches to fix cgroup_freezer breakage due to the recent

  that while holding a spin lock.  cgroup_freezer was using an overly
  elaborate hierarchical locking scheme.

  While it's possible to convert the hierarchical spinlocks directly to
  mutexes, this patch simplifies the overall locking so that it uses a
  global mutex.  This has the added benefit of avoiding iterating
  potentially huge number of tasks under a spinlock.  While the patch is
  on the larger side in the devel cycle, the changes made are mostly
  straight-forward and the locking logic is a lot simpler afterwards"

478c7cf7a8 ACPI and power management fixes for 3.15-rc6
- ACPICA fix for a stale pointer access introduced by a recent
    commit in the XSDT validation code from Lv Zheng.
 
  - ACPICA fix for the default value of the command line switch
    to favor 32-bit FADT addresses (in case there's a conflict
    between a 64-bit and a 32-bit address).  The previous default
    was that the 32-bit version would take precedence and we tried
    to change it to the other way around and it didn't work.
    From Lv Zheng.
 
  - A TPM commit related to ACPI _DSM in 3.14 caused the driver to
    refuse to load if a specific _DSM was missing and that broke
    resume from system suspend on Chromebooks that require the TPM
    hardware to be restored to a working state during resume by the
    OS.  Restore the old behavior to load the driver if the _DSM
    in question is not present, but prevent it from using the
    feature the _DSM is for.
 
  - ACPI AC driver conversion in 3.13 broke thermal management on
    at least one machine and has to be reverted.  From Guenter Roeck.
 
  - Two reverts of 3.13 commits that attempted to remove the old ACPI
    battery interface in /proc, but turned out to break some utilities
    still using that interface.  From Lan Tianyu.
 
  - ACPI processor driver fix to prevent acpi_processor_add() from
    modifying the CPU device's .offline field which leads to breakage
    if the initial online of the CPU fails.  From Igor Mammedov.
 
  - Two intel_pstate fixes, one to take a BayTrail documentation update
    into account and one to avoid forcing the maximum P-state on init
    which causes CPU PM trouble on systems with P-states coordination
    when one of the CPU cores is initialized after an offline/online
    cycle triggered by user space.  Both stable candidates, from
    Dirk Brandewie.
 
  - Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
    from Aaron Lu.
 
  - Two new ACPI video blacklist entries for machines shipping with
    Win8 that need to use native backlight so that it can be controlled
    in a usual way (which doesn't work otherwise due bugs in the ACPI
    tables) from Hans de Goede.

 "Still fixing regressions (partly by reverting commits that broke
  things for people), fixing other stable-candidate bugs and adding some

  Two ACPICA regression fixes (one recent and one for a 3.14 commit), a

This branch contains bug fixes important to get into v3.15. There is a
 fix for modifying properties seen during early boot, a fix for an
 incorrect prototype when CONFIG_OF=n, and a couple of corrections to
 device tree memory nodes on  a few platforms.

51a60253a5 Btrfs: send, fix incorrect ref access when using extrefs
When running send, if an inode only has extended reference items
associated to it and no regular references, send.c:get_first_ref()
was incorrectly assuming the reference it found was of type
BTRFS_INODE_REF_KEY due to use of the wrong key variable.
This caused weird behaviour when using the found item has a regular
reference, such as weird path string, and occasionally (when lucky)
a crash:

d3ecfcdf91 Btrfs: fix EIO on reading file after ioctl clone works on it
For inline data extent, we need to make its length aligned, otherwise,
we can get a phantom extent map which confuses readpages() to return -EIO.

This can be detected by xfstests/btrfs/035.

Unfortunately this update became bigger than previous pull requests,
 which is almost a pattern in rc5-6.  But, the only obvious big changes
 are for the new Intel DSP ASoC drivers, so the impact must be fairly
 limited.
 
 Other than that, usual small fixes in various fields: HD-audio, ASoC
 core and ASoC fsl and codec drivers.

  The second patch ratelimits printing of userspace segfaults in the

Mostly fixes for metag and parisc relating to upgrowing stacks.
 
 * Fix missing compiler barriers in metag memory barriers.
 * Fix BUG_ON on metag when RLIMIT_STACK hard limit is increased beyond
   safe value.
 * Make maximum stack size configurable. This reduces the default user
   stack size back to 80MB (especially on parisc after their removal of
   _STK_LIM_MAX override). This only affects metag and parisc.
 * Remove metag _STK_LIM_MAX override to match other arches and follow
   parisc, now that it is safe to do so (due to the BUG_ON fix mentioned
   above).
 * Finally now that both metag and parisc _STK_LIM_MAX overrides have
   been removed, it makes sense to remove _STK_LIM_MAX altogether.

 "Mostly fixes for metag and parisc relating to upgrowing stacks.

   - Fix missing compiler barriers in metag memory barriers.
   - Fix BUG_ON on metag when RLIMIT_STACK hard limit is increased
     beyond safe value.
   - Make maximum stack size configurable.  This reduces the default
     user stack size back to 80MB (especially on parisc after their
     removal of _STK_LIM_MAX override).  This only affects metag and
     parisc.
   - Remove metag _STK_LIM_MAX override to match other arches and follow
     parisc, now that it is safe to do so (due to the BUG_ON fix
     mentioned above).
   - Finally now that both metag and parisc _STK_LIM_MAX overrides have
     been removed, it makes sense to remove _STK_LIM_MAX altogether"

f5c16f29bf sysfs: make sure read buffer is zeroed
13c589d5b0 ("sysfs: use seq_file when reading regular files")
switched sysfs from custom read implementation to seq_file to enable
later transition to kernfs.  After the change, the buffer passed to
->show() is acquired through seq_get_buf(); unfortunately, this
introduces a subtle behavior change.  Before the commit, the buffer
passed to ->show() was always zero as it was allocated using
get_zeroed_page().  Because seq_file doesn't clear buffers on
allocation and neither does seq_get_buf(), after the commit, depending
on the behavior of ->show(), we may end up exposing uninitialized data
to userland thus possibly altering userland visible behavior and
leaking information.

Fix it by explicitly clearing the buffer.

3685f25161 ahci: imx: PLL clock needs 100us to settle down
The commit e783c51 (ahci: imx: software workaround for phy reset issue
in resume) calls imx_sata_phy_reset() to reset phy immediately after
SATA MPLL is enabled.  It seems working fine mostly, but fails in some
case as below.

...
ahci-imx 2200000.sata: failed to reset phy: -110
ahci-imx: probe of 2200000.sata failed with error -110

After talking to the designer, we learnt that when enabling i.MX6Q SATA
MPLL, we need to wait 100us for it to settle down for safety.  Add this
required delay to fix above failure.
