Three small fixes for the current cycle:
 * missing netlink attribute check in hwsim wmediumd (Martin)
 * fast xmit structure alignment fix (Felix)
 * mesh path flush/synchronisation fix (Bob)

A bunch of GPIO fixes for the v4.7 series:

- Drop the lock before reading out the GPIO direction
  setting in drivers supporting the .get_direction()
  callback: some of them may be slowpath.

- Flush GPIO direction setting before locking a GPIO as an
  IRQ: some electronics or other poking around in the
  registers behind our back may have happened, so flush
  the direction status before trying to lock the line for
  use by IRQs.

- Bail out silently when asked to perform operations on
  NULL GPIO descriptors. That is what all the get_*_optional()
  is about: we get optional GPIO handles, if they are not
  there, we get NULL.

- Handle compatible ioctl() correctly: we need to convert
  the ioctl() pointer using compat_ptr() here like everyone
  else.

- Disable the broken .to_irq() on the LPC32xx platform.
  The whole irqchip infrastructure was replaced in the
  last merge window, and a new implementation will be
  needed.

Linux 4.7-rc1

sound updates #2 for 4.7-rc1

This is the second update round for 4.7-rc1.  Most of changes are
about the pending ASoC updates and fixes, including a few new
drivers.  Below are some highlights:

ASoC:
- New drivers for MAX98371 and TAS5720
- SPI support for TLV320AIC32x4, along with the module split
- TDM support for STI Uniperf IPs
- Remaining topology API fixes / updates

HDA:
- A couple of Dell quirks and new Realtek codec support

ASoC: Updates for v4.7 part 2

Really sorry about this late pull request.  It looks like at the time I
sent my pull request for v4.7 there was some conflict or other issue
which caused my script to stop merging the ASoC branches at some point
after the HDMI changes.

It's all specific driver updates, including:

 - New drivers for MAX98371 and TAS5720.
 - SPI support for TLV320AIC32x4.
 - TDM support for STI Uniperf IPs.

This code should all have been in -next prior to the merge window apart
from some fixes, it dropped out on the 18th.

Additional ACPI update for v4.7-rc1

Just one fix for incorrect async_synchronize_cookie() usage in the
ACPI battery driver (Chris Wilson).

More power management updates for v4.7-rc1

 - Stable-candidate cpuidle fix to make it check the right variable
   when deciding whether or not to enable interrupts on the local CPU
   so as to avoid enabling iterrupts too early in some cases if the
   system has both coupled and per-core idle states (Daniel Lezcano).

 - Stable-candidate PM core fix to make it handle failures at the
   "late suspend" stage of device suspend consistently for all
   devices regardless of whether or not async suspend/resume is
   enabled for them (Rafael Wysocki).

 - Cleanups in the cpufreq core, the schedutil governor and the
   intel_pstate driver (Rafael Wysocki, Pankaj Gupta, Viresh Kumar).

This is the 3.12.60 stable release

- cmd-parser support for direct reg->reg loads (Ken Graunke)
- better handle DP++ smart dongles (Ville)
- bxt guc fw loading support (Nick Hoathe)
- remove a bunch of struct typedefs from dpll code (Ander)
- tons of small work all over to avoid casting between drm_device and the i915
  dev struct (Tvrtko&Chris)
- untangle request retiring from other operations, also fixes reset stat corner
  cases (Chris)
- skl atomic watermark support from Matt Roper, yay!
- various wm handling bugfixes from Ville
- big pile of cdclck rework for bxt/skl (Ville)
- CABC (Content Adaptive Brigthness Control) for dsi panels (Jani&Deepak M)
- nonblocking atomic commits for plane-only updates (Maarten Lankhorst)
- bunch of PSR fixes&improvements
- untangle our map/pin/sg_iter code a bit (Dave Gordon)

Linux 3.18.34

Linux 4.1.25

Devicetree for 4.7:

- Rewrite of the unflattening code to avoid recursion and lessen the
  stack usage.

- Rewrite of the phandle args parsing code to get rid of the fixed args
  size. This is needed for IOMMU code.

- Sync to latest dtc which adds more dts style checking. These warnings
  are enabled with "W=1" compiles.

- Tegra documentation updates related to the above warnings.

- A bunch of spelling and other doc fixes.

- Various vendor prefix additions.

IOMMU Updates for Linux v4.7

The updates include:

	* Rate limiting for the VT-d fault handler

	* Remove statistics code from the AMD IOMMU driver. It is unused
	  and should be replaced by something more generic if needed

	* Per-domain pagesize-bitmaps in IOMMU core code to support
	  systems with different types of IOMMUs

	* Support for ACPI devices in the AMD IOMMU driver

	* 4GB mode support for Mediatek IOMMU driver

	* ARM-SMMU updates from Will Deacon:

		- Support for 64k pages with SMMUv1 implementations
		  (e.g MMU-401)

		- Remove open-coded 64-bit MMIO accessors

		- Initial support for 16-bit VMIDs, as supported by some
		  ThunderX SMMU implementations

		- A couple of errata workarounds for silicon in the
		  field

	* Various fixes here and there

sound updates for 4.7-rc1

This time was again a relatively calm development cycle; most of
updates are about drivers, and no radical changes are seen in any
core code.  Here are some highlights:

ALSA core:
- Continued hardening of ALSA hrtimer
- A few leak fixes in timer interface
- Fix poll error handling in PCM and compress
- Add error propagation in compress API
- Removal of dead rtctimer driver

HD-audio:
- Native ELD notify support for i915 HDMI
- Realtek ALC234 & co support
- Code refactoring to standardize chmap support
- Continued development for SKL HDMI core support

Firewire:
- Apply delayed card registration to all drivers
- Improved / stabilized the handling of PCM stream start / stop
- Add tracepoints to dump a part of isochronous packet data
- Fixed incoming/outgoing packet parameter usages
- Add support for M-Audio profire series

USB-audio:
- Fixes for UAC2 clock source
- SS+ support
- Workaround for oft-seen repeated sample rate read errors

ASoC:
- Further slow progress on the topology code
- Substantial updates and improvements for the da7219, es8328,
  fsl-ssi, Intel and rcar drivers.
- Compress error handling in WM ADSP driver

This is the 4.5.5 stable release
