Merge tag 'linux_kselftest-next-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull kselftest updates from Shuah Khan:

 - make framework and tests reporting KTAP compliant

 - make ktap_helpers and power_supply test POSIX compliant

 - add ksft_exit_fail_perror() to include errono in string form

 - avoid clang reporting false positive static analysis errors about
   functions that exit and never return. ksft_exit* functions are marked
   __noreturn to address this problem

 - add mechanism for reporting a KSFT_ result code

 - fix build warnings related missing headers and unused variables

 - fix clang build failures

 - cleanups to resctrl test

 - add host arch for LLVM builds
