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.
