The formatting in the patch is wrong (multiple issues).

I don't see a point in the __atomic_load_n (addr, MEMMODEL_RELAXED), for
aligned ints or pointers the loads are atomic on all architectures libgomp is
supported on, after all kernel is also using just a normal load in the futex
syscall, not __atomic_load_n (which expands to the normal load only anyway).
