[patch 3/6] add init declaration to memory initialization functions

From: Chen, Kenneth W <kenneth.w.chen_at_intel.com>
Date: 2006-03-13 04:04:54
Add init declaration to variables/functions used for memory
initialization.  I don't think they would clash with memory
hotplug.  If they do, please yell.
