Subject: [PATCH] tools headers UAPI: Sync x86 arch prctl headers with the
 kernel sources

To pick the changes in this cset:

  980fe2fddcff2193 ("x86/fpu: Extend fpu_xstate_prctl() with guest permissions")

This picks these new prctls:

With this 'perf trace' can translate those numbers into strings and use
the strings in filter expressions:

This addresses these perf build warnings:

  Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/prctl.h' differs from latest version at 'arch/x86/include/uapi/asm/prctl.h'
