Subject: [Patch:002/005] wait_table and zonelist initializing for memory hotadd (change to meminit for build_zonelist)
Date: Tue, 11 Apr 2006 20:30:25 +0900 [thread overview]
Message-ID: <20060411202606.5647.Y-GOTO@jp.fujitsu.com> (raw)
In-Reply-To: <20060411202031.5643.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.
