tools headers UAPI: Sync linux/prctl.h with the kernel sources
To pick the changes in:
433c38f40f6a81cf ("arm64: mte: change ASYNC and SYNC TCF settings into bitfields")
e893bb1bb4d2eb63 ("x86, prctl: Hook L1D flushing in via prctl")
That don't result in any changes in tooling:
$ tools/perf/trace/beauty/prctl_option.sh > before
$ cp include/uapi/linux/prctl.h tools/include/uapi/linux/prctl.h
$ tools/perf/trace/beauty/prctl_option.sh > after
$ diff -u before after
$
Just silences this perf tools build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h'
