Mateusz Guzik 83362d2237 mm/hugetlb: sort out global lock annotations ... The mutex array pointer shares a cacheline with the spinlock: ffffffff84187480 B hugetlb_fault_mutex_table ffffffff84187488 B hugetlb_lock This is because the former is annotated with a macro forcing cacheline alignment. I suspect it was meant to be the variant which on top of it makes sure the object does not share the cacheline with anyone. Since array pointer itself is de facto read-only such an annotation does not make sense there anyway. Instead mark it __ro_after_init along with the size var. Do however move the spinlock out of the way.
