[PATCH: 013/017]Memory hotplug for new nodes v.4.(changes from __init to __meminit)

From: Yasunori Goto <y-goto_at_jp.fujitsu.com>
Date: 2006-03-17 19:22:45
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.
