Arnaldo Carvalho de Melo 8326c79d10 tools headers UAPI: Sync x86 arch prctl headers with the kernel sources
To pick the changes in this cset:

  980fe2fddc ("x86/fpu: Extend fpu_xstate_prctl() with guest permissions")

This picks these new prctls:

  $ tools/perf/trace/beauty/x86_arch_prctl.sh > /tmp/before
  $ cp arch/x86/include/uapi/asm/prctl.h tools/arch/x86/include/uapi/asm/prctl.h

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

  # perf trace -e prctl

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'
