Build error log for um:defconfig:

ipc/sem.c: In function 'complexmode_tryleave':
ipc/sem.c:317:2: error: implicit declaration of function 'smp_store_release'
ipc/sem.c: In function 'sem_lock':
ipc/sem.c:370:3: error: implicit declaration of function 'smp_load_acquire'

Culprit is commit a198951bf258 ("ipc/sem.c: fix complex_count vs. simple op race"),
and reverting it fixes the problem. Copying the patch author for feedback.
