Merge tag 'linux-kselftest-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull Kselftest update from Shuah Khan:

 - Work to restructure timers test suite to move PIE out of rtctest from
   Alexandre Belloni.

 - Several minor spelling and bug fixes.

 - New cgroup tests from Roman Gushchin and Mike Rapoport.

 - Kselftest framework changes to handle and report skipped tests
   correctly.

   Prior to these changes, framework treated all non-zero return codes
   from tests as failures. When tests are skipped with non-zero return
   code, due to unmet dependencies and/or unsupported configuration,
   reporting them as failed lead to false negatives on the tests that
   couldn't be run.

 - Fixes to test Makefiles to remove unnecessary RUN_TESTS and
   EMIT_TESTS overrides and use common defines from lib.mk.

 - Fixes to several tests to return correct Kselftest skip code.

 - Changes to improve test output.
