linux-kselftest-next-5.15-rc1

This Kselftest update for Linux 5.15-rc1 consists of fixes to build
 and test failures.
 
 -- openat2 test failure for O_LARGEFILE flag on ARM64
 -- x86 test build failures related to glibc 2.34 adding
    support for variable sized MINSIGSTKSZ and SIGSTKSZ
 -- removing obsolete configs in sync and cpufreq config files
 -- minor spelling and duplicate header include cleanups
