ARM: 6891/1: prevent heap corruption in OABI semtimedop
commit 0f22072ab50cac7983f9660d33974b45184da4f9 upstream.
When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does not
bound the nsops argument. A sufficiently large value will cause an
integer overflow in allocation size, followed by copying too much data
into the allocated buffer. Fix this by restricting nsops to SEMOPM.
Untested.
