Subject[PATCH 5/9] mm/mm_init.c: use hotplug_memory_notifier() directly
Date
Since patch 316346243be6 has already updated the minimum gcc version to 5.1.
The previous problem mentioned in patch f02c69680088 is not existed. So we
can now revert to use hotplug_memory_notifier() directly rather than
register_hotmemory_notifier().
