    ipc/compat.c: remove sc_semopm macro · 187841a8
    Davidlohr Bueso authored
    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.
