        src/sys/arch/mips/mips: lock_stubs_llsc.S

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.
