Linux 5.10-rc1

Two patches to prevent out-of-bands accesses on fonts buffers

linux-kselftest-kunit-5.10-rc1

This Kunit update for Linux 5.10-rc1 consists of:

- add Kunit to kernel_init() and remove KUnit from init calls entirely.
  This addresses the concern Kunit would not work correctly during
  late init phase.
- add a linker section where KUnit can put references to its test suites.
  This patch is the first step in transitioning to dispatching all KUnit
  tests from a centralized executor rather than having each as its own
  separate late_initcall.
- add a centralized executor to dispatch tests rather than relying on
  late_initcall to schedule each test suite separately. Centralized
  execution is for built-in tests only; modules will execute tests when
  loaded.
- convert bitfield test to use KUnit framework
- Documentation updates for naming guidelines and how kunit_test_suite()
  works.
- add test plan to KUnit TAP format

linux-kselftest-kunit-fixes-5.10-rc1

This Kunit fixes update consists of several kunit tool bug fixes in
flag handling, run outside kernel tree, make errors, and generating
results.

linux-kselftest-next-5.10-rc1

This kselftest update for Linux 5.10-rc1 consists of enhancements to

-- speed up headers_install done during selftest build
-- add generic make nesting support
-- add support to select individual tests:
   - Selftests build/install generates run_kselftest.sh script to run
     selftests on a target system. Currently the script doesn't have
     support for selecting individual tests. Add support for it.

     With this enhancement, user can select test collections (or tests)
     individually. e.g:

     run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep

     Additionally adds a way to list all known tests with "-l", usage
     with "-h", and perform a dry run without running tests with "-n".

linux-kselftest-fixes-5.10-rc1

This kselftest fixes update consists of a selftests harness fix to
flush stdout before forking to avoid parent and child printing
duplicates messages. This is evident when test output is redirected
to a file.

The second fix is a tools/ wide change to avoid comma separated statements
from Joe Perches. This fix spans tools/lib, tools/power/cpupower, and
selftests.

One fix for a bad revert in ingenic-drm, and one fix for panfrost to increase a timeout at power up.

Linux 5.9

One MAINTAINERS change and a revert for a compilation breakage in next for
ingenic
