Subject: [PATCH REPOST] [2/3] Move early exception handlers into init.text
Date: Monday, March 10, 2008 - 6:23 pm

Currently they are in .text.head because the rest of head_64.S. 
.text.head is not removed as init data, but the early exception handlers
should be because they are not needed after early boot of the BP. 
So move them over.
