    lib/libthr/arch/amd64/amd64 _umtx_op_err.S 
    lib/libthr/arch/i386/i386 _umtx_op_err.S 
  Log:
  Replace function _umtx_op with _umtx_op_err, the later function directly
  returns errno, because errno can be mucked by user's signal handler and
  most of pthread api heavily depends on errno to be correct, this change
  should improve stability of the thread library.
