3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Davidlohr Bueso <davidlohr.bueso@xxxxxx>
commit 9ad66ae65fc8d3e7e3344310fb0aa835910264fe upstream.
We can now drop the msg_lock and msg_lock_check functions along with a
bogus comment introduced previously in semctl_down.
