It may also want part of this one... 
     53dad6d3a8e5ac1af8bacc6ac2134ae1a8b085f1 ipc: fix race with LSMs
..this one..
     d8c633766ad88527f25d9f81a5c2f083d78a2b39 ipc/sem.c: synchronize the proc interface
..and this one from mmotm.
     ipc-semc-synchronize-semop-and-semctl-with-ipc_rmid.patch

I didn't look hard though, that's just what sticks out when I look at my
