[PATCH: 013/017](RFC) Memory hotplug for new nodes v.3. (changes from __init to __meminit)

[Yasunori Goto <y-goto@jp.fujitsu.com>]

This is a patch to change definition of some functions and data
from __init to __meminit.
These functions and data can be used after bootup by this patch to
be used for hot-add codes.
