	  When onlining memory blocks, this option helps to add the target
	  memory block to ZONE_MOVABLE zone type. For successful offlining,
	  these memory blocks should belong to 'ZONE_MOVABLE' since it carries
	  only movable pages. When this option is not set, the default zone
	  policy is to add the blocks to 'ZONE_NORMAL' which may pin pages.

	  See Documentation/memory-hotplug.txt for more information.
