Merge tag 'linux-kselftest-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull kselftest updates form Shuah Khan:

 - TAP output reporting related fixes from Paolo Bonzini and Kees Cook.

   These fixes make it skip reporting consistent with TAP format.

 - Cleanup fixes to framework run_tests from Yauheni Kaliuta
