ipc/compat.c: remove sc_semopm macro
This macro appears to have been introduced back in the 2.5 era for
semtimedop32 backward compatibility on ia32:
https://lkml.org/lkml/2003/4/28/78
Nowadays, this syscall in compat just defaults back to the code found in
sem.c, so it is no longer used and can thus be removed:
long compat_sys_semtimedop(int semid, struct sembuf __user *tsems,
unsigned nsops, const struct compat_timespec __user *timeout)
{
struct timespec __user *ts64;
if (compat_convert_timespec(&ts64, timeout))
return -EFAULT;
return sys_semtimedop(semid, tsems, nsops, ts64);
}
Furthermore, there are no users in compat.c. After this change, kernel
builds just fine with both CONFIG_SYSVIPC_COMPAT and CONFIG_SYSVIPC.
