Joonsoo Kim b9eb63191a mm/memory_hotplug: add comment to some functions related to memory hotplug 
__offline_isolated_pages() and test_pages_isolated() are used by memory
hotplug.  These functions require that range is in a single zone but
there is no code to do this because memory hotplug checks it before
calling these functions.  To avoid confusing future user of these
functions, this patch adds comments to them.
