The big thing this release has been Liam's addition of topology support
to the core. We've also seen quite a bit of driver work and the
continuation of Lars' refactoring for component support.
- Support for loading ASoC topology maps from firmware, intended to be
used to allow self-describing DSP firmware images to be built which
can map controls added by the DSP to userspace without the kernel
needing to know about individual DSP firmwares.
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring.
- Big refactoring and cleanup serieses for the Wolfson ADSP and TI
TAS2552 drivers.
- Support for TI TAS571x power amplifiers.
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
- Support for x86 systems with RT5650 and Qualcomm Storm.

The Marvell Armada 38x SoC introduce new features to the XOR engine,
especially the fact that the engine mode (MEMCPY/XOR/PQ/etc) can be part of
the descriptor and not set through the controller registers.
This new feature allows mixing of different commands (even PQ) on the same
channel/chain without the need to stop the engine to reconfigure the engine
mode.
Refactor the driver to be able to use that new feature on the Armada 38x,
while keeping the old behaviour on the older SoCs.

iput() and evict() is run after write pages to block device, if
write pages work is not finished before next write, the "rm"ed space
is not freed, and caused above bug.

We can add "-o flushoncommit" mount option to avoid above bug, but

__btrfs_inc_extent_ref() and __btrfs_free_extent() have already had too

the rest will only add/sub exclusive extents, where node is not used.

The embedded UART is apparently used to receive decoded IR (RC5?) codes.
Forward these scan codes to the RC framework and (where known) add
corresponding mapping tables to translate them into regular keys.
This patch has been tested on a TechniSat CableStar HD2. The mappings of other
rc-maps were taken from Christoph Pinkl's patch
(http://patchwork.linuxtv.org/patch/7217/) and the s2-liplianin repository. The
major difference to Christoph's patch is a reworked interrupt handling of the
UART because the RX interrupt is apparently level triggered and requires
masking until the FIFO is read by the UART worker.

Use unique temporary files when copying to buildid dir to prevent races
in case multiple instances are trying to copy same file. This is done by
- creating template in form <path>/.<filename>.XXXXXX where the suffix is
used by mkstemp() to create unique file
- change file mode
- copy content
- if successful link temp file to target file
- unlink temp file
At this point the only file left at target path should be the desired
one either created by us or other instance if we raced. This should also
prevent not yet fully copied files to be visible to to other perf
instances that could try to parse them.
On top of that slow_copyfile no longer needs to deal with file mode when
creating file since temporary file is already created and mode is set.
Succesfully tested by myself by running perf record, archive and reading
the data on other system and by running perf buildid-cache on perf
binary itself. I also did revert fix from 0635b0f that to exposes
previously fixed race with EEXIST and recreator test passed sucessfully.
