Log Message:
mips: Issue a sync plunger at the end of mutex_spin_exit.
Same as mutex_exit. Relevant only on cnMIPS where the store buffers
get clogged. Recommended by the Cavium documentation. No semantic
change, only performance -- this only adds a barrier in some cases
where there was none before, so it can't hurt correctness.
