    tools headers UAPI: Sync files changed by new process_mrelease syscall and the removal of some compat entry points
    
    To pick the changes in these csets:
    
      59ab844e ("compat: remove some compat entry points")
      dce49103 ("mm: wire up syscall process_mrelease")
      b48c7236 ("exit/bdflush: Remove the deprecated bdflush system call")
    
    That add support for this new syscall in tools such as 'perf trace'.
    
    For instance, this is now possible:
    
      # perf trace -v -e process_mrelease
      event qualifier tracepoint filter: (common_pid != 19351 && common_pid != 9112) && (id == 448)
      ^C#
    
    That is the filter expression attached to the raw_syscalls:sys_{enter,exit}
    tracepoints.
    
      $ grep process_mrelease tools/perf/arch/x86/entry/syscalls/syscall_64.tbl
      448    common  process_mrelease            sys_process_mrelease
      $
    
    This addresses these perf build warnings:
