    tools headers UAPI: Sync files changed by the memfd_secret new syscall · 376a9476

    To pick the changes in this cset:
    
      7bb7f2ac
    
     ("arch, mm: wire up memfd_secret system call where relevant")
    
    That silences these perf build warnings and add support for those new
    syscalls in tools such as 'perf trace'.
    
    For instance, this is now possible:
    
      # perf trace -v -e memfd_secret
      event qualifier tracepoint filter: (common_pid != 13375 && common_pid != 3713) && (id == 447)
      ^C#
    
    That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
    tracepoints.
    
      $ grep memfd_secret tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
      447    common  memfd_secret            sys_memfd_secret
      $
    
    This addresses these perf build warnings:
