mm/memory_hotplug: preparatory patches for new online policy and memory

[David Hildenbrand <david@redhat.com>]

Hi,

these are all cleanups and one fix previously sent as part of [1]:
	[PATCH v1 00/12] mm/memory_hotplug: "auto-movable" online policy
	and memory groups

These patches make sense even without the other series, therefore I pulled
them out to make the other series easier to digest.
