Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver updates for 5.18-rc1.

  Loads of tiny cleanups for almost all staging drivers in here, nothing
  major at all. Highlights include:

   - remove the ashmem Android driver. It is long-dead and if there are
     any legacy userspace applications still using it, the Android
     kernel images will maintain it, the community shouldn't care about
     it anymore

   - wfx wifi driver major cleanups. Should be ready to merge out of
     staging soon, and will coordinate with the wifi maintainers after
     -rc1 is out

   - major cleanups and unwinding of the layers of the r8188eu driver.
     It's amazing just how many unneeded layers of abstraction is in
     there, just when we think it's done, another is found...

   - lots of tiny coding style cleanups in many other staging drivers.

  All have been in linux-next for a while with no reported problems"

The MT7621 system-on-a-chip includes an 880 MHz MIPS1004Kc dual-core CPU,
a 5-port 10/100/1000 switch/PHY and one RGMII.

Add the devicetrees for GB-PC1 and GB-PC2 devices which use MT7621 SoC.

Originally we proposed a new hdmi-5v-supply regulator reference
for CI20 device tree but that was superseded by a better idea to use
the already defined "ddc-en-gpios" property of the "hdmi-connector".

Since "MIPS: DTS: CI20: Add DT nodes for HDMI setup" has already
been applied to v5.17-rc1, we add this on top.

Pull Kbuild updates from Masahiro Yamada:

 - Add new kconfig target 'make mod2noconfig', which will be useful to
   speed up the build and test iteration.

 - Raise the minimum supported version of LLVM to 11.0.0

 - Refactor certs/Makefile

 - Change the format of include/config/auto.conf to stop double-quoting
   string type CONFIG options.

 - Fix ARCH=sh builds in dash

 - Separate compression macros for general purposes (cmd_bzip2 etc.) and
   the ones for decompressors (cmd_bzip2_with_size etc.)

 - Misc Makefile cleanups

GZIP-compressed files end with 4 byte data that represents the size
of the original input. The decompressors (the self-extracting kernel)
exploit it to know the vmlinux size beforehand. To mimic the GZIP's
trailer, Kbuild provides cmd_{bzip2,lzma,lzo,lz4,xzkern,zstd22}.
Unfortunately these macros are used everywhere despite the appended
size data is only useful for the decompressors.

There is no guarantee that such hand-crafted trailers are safely ignored.
In fact, the kernel refuses compressed initramdfs with the garbage data.
That is why usr/Makefile overrides size_append to make it no-op.

To limit the use of such broken compressed files, this commit renames
the existing macros as follows:

  cmd_bzip2   --&gt; cmd_bzip2_with_size
  cmd_lzma    --&gt; cmd_lzma_with_size
  cmd_lzo     --&gt; cmd_lzo_with_size
  cmd_lz4     --&gt; cmd_lz4_with_size
  cmd_xzkern  --&gt; cmd_xzkern_with_size
  cmd_zstd22  --&gt; cmd_zstd22_with_size

To keep the decompressors working, I updated the following Makefiles
accordingly:

  arch/arm/boot/compressed/Makefile
  arch/h8300/boot/compressed/Makefile
  arch/mips/boot/compressed/Makefile
  arch/parisc/boot/compressed/Makefile
  arch/s390/boot/compressed/Makefile
  arch/sh/boot/compressed/Makefile
  arch/x86/boot/compressed/Makefile

I reused the current macro names for the normal usecases; they produce
the compressed data in the proper format.

I did not touch the following:

  arch/arc/boot/Makefile
  arch/arm64/boot/Makefile
  arch/csky/boot/Makefile
  arch/mips/boot/Makefile
  arch/riscv/boot/Makefile
  arch/sh/boot/Makefile
  kernel/Makefile

This means those Makefiles will stop appending the size data.

I dropped the 'override size_append' hack from usr/Makefile.
