 "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"
