No. I think it's ok for __alloc_pages() to call oom_kill()
IF we turn out to be out of memory, but that should not even
be needed.
Also, when a task in __alloc_pages() is OOM-killed, it will
have PF_MEMALLOC set and will immediately break out of the
loop. The rest of the system will spin around in the loop
until the victim has exited and then their allocations will
succeed.
