linux-kselftest-5.5-rc1-fixes2

This second Kselftest fixes update for Linux 5.5-rc1 consists of
an urgent revert to fix regression in CI coverage.

mm + drm coherent memory support for vmwgfx

- Important fix to uAPI alignment on query IOCTL
- Fixes for the power regression introduced by the previous security patches
- Avoid regressing super heavy benchmarks by increasing the default request pre-emption timeout from 100 ms to 640 ms to
- Resulting set of smaller fixes done while problem was inspected
- Display fixes for EHL voltage level programming and TGL DKL PHY vswing for HDMI

drm main pull for 5.5-rc1

sound updates for 5.5-rc1

There have been some significant changes in the core side, both for
ALSA and ASoC, while lots of development have been seen in SOF, as
well as many small fixes/improvements for ASoC codecs and platforms.
Below is a highlight in this cycle:

Core:
- The unification of PCM vmalloc buffer allocation helpers into the
  standard API
- Clean up of the default PCM mmap handling for vmalloc & SG-buffer
- Fix potential races at ALSA timer open
- A few new PCM API extensions; just preliminary core changes, the
  actual changes in drivers will be merged in 5.6
- Continued ASoC componentization works; now almost everything is a
  common ASoC component object.  A lot of refactoring and
  simplification have been done along with it.

ASoC:
- Many fixes to the Sound Open Firmware (SOF) code
- Wake on voice support for Chromebooks
- SPI support and trigger word detection for RT5677
- New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
  with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770

HD-audio:
- Improved Intel DSP configuration / probe code for SOF
- Plumbing the legacy HD-audio driver with Intel SOF HDMI
- DP-MST support for Nvidia HDMI codecs
- Realtek quirks cleanups and new additions as usual

Others:
- Lots of refactoring and cleanups for FireWire; period-size sharing,
  h/w IRQ interval configuration, clock recovery improvements, etc
- USB-audio: Scarlett mixer quirks
- Cleanups of PCM calls in various drivers (including media and USB)
  to adapt the core API changes

 - A fix for a memory leak in the dma-buf support
 - One in mcde DSI support that leads to a pointer dereference

Linux 5.4

linux-kselftest-5.5-rc1-kunit

This kselftest update for Linux 5.5-rc1 adds KUnit, a lightweight unit
testing and mocking framework for the Linux kernel from Brendan Higgins.

KUnit is not an end-to-end testing framework. It is currently supported
on UML and sub-systems can write unit tests and run them in UML env.
KUnit documentation is included in this update.

In addition, this Kunit update adds 3 new kunit tests:

- kunit test for proc sysctl from Iurii Zaikin
- kunit test for the 'list' doubly linked list from David Gow
- ext4 kunit test for decoding extended timestamps from Iurii Zaikin

In the future KUnit will be linked to Kselftest framework to provide
a way to trigger KUnit tests from user-space.

linux-kselftest-5.5-rc1-fixes

This kselftest fixes update for Linux 5.5-rc1 consists of several
fixes to tests and framework. Masami Hiramatsu fixed several tests
