- LK macro (conditional on SMP for the lock prefix) is unused - SETLK unnecessarily performs xchg. obtained value is never used and the implicit lock prefix adds avoidable cost. Barrier provided by it does not appear to be of any use. - the lock waited for is almost never blocked, yet the loop starts with a pause. Move it out of the common case.
