Subject: [PATCH REPOST] [2/3] Move early exception handlers into init.text
Date: Tue,  4 Mar 2008 22:13:31 +0100 (CET)	[thread overview]
Message-ID: <20080304211331.2A7D01B4199@basil.firstfloor.org> (raw)
In-Reply-To: <200803041013.139953228@firstfloor.org>


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.
