3.16.7-ckt9 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Rob Gardner <rob.gardner@xxxxxxxxxx>
commit 53eb2516972b8c4628651dfcb926cb9ef8b2864a upstream.
A bug was reported that the semtimedop() system call was always
failing eith ENOSYS.
Since SEMCTL is defined as 3, and SEMTIMEDOP is defined as 4,
the comparison "call <= SEMCTL" will always prevent SEMTIMEDOP
from getting through to the semaphore ops switch statement.
This is corrected by changing the comparison to "call <= SEMTIMEDOP".
