    This will be used by 'perf trace' to show these strings when beautifying
    the prctl syscall args. At some point we'll be able to say something
    like:
    
    	'perf trace --all-cpus -e prctl(option=*SPEC*)'
    
    To filter by arg by name.
    
      This silences this warning when building tools/perf:
    
        Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h'
