Memory hotplug is a logic for making pages unused in the specified
range of pfn. So, some of core logics can be used for other purpose
as allocating a very large contigous memory block.

This patch moves some functions from mm/memory_hotplug.c to
mm/page_isolation.c. This helps adding a function for large-alloc in
page_isolation.c with memory-unplug technique.
