Merge tag 'linux-kselftest-nolibc-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull nolibc updates from Shuah Khan:
 "Nolibc:
   - improved portability by removing build errors with -ENOSYS
   - added syscall6() on MIPS to support pselect6() and mmap()
   - added setvbuf(), rmdir(), pipe(), pipe2()
   - add support for ppc/ppc64
   - environ is no longer optional
   - fixed frame pointer issues at -O0
   - dropped sys_stat() in favor of sys_statx()
   - centralized _start_c() to remove lots of asm code
   - switched size_t to __SIZE_TYPE__

  Selftests:
   - improved status reporting (success/warning/failure counts, path to
     log file)
   - various code cleanups (indent, unused variables, ...)
   - more consistent test numbering
   - enabled compiler warnings
   - dropped unreliable chmod_net test
   - improved reliability (create /dev/zero & /tmp, rely less on /proc)
   - new tests (brk/sbrk/mmap/munmap)
   - improved compatibility with musl
   - new run-nolibc-test target to build and run natively
   - new run-libc-test target to build and run against native libc
   - made the cmdline parser more reliable against boolean arguments
   - dropped dependency on memfd for vfprintf() test
   - nolibc-test is no longer stripped
   - added support for extending ARCH via XARCH

  Other:
   - add Thomas as co-maintainer"
