Subject: [PATCH 1/3] radeonfb: Fix 64 bits resources on 32 bits archs

From: Benjamin Herrenschmidt <[email-masked]>
Date: Tue, 22 Apr 2008 11:26:07 +1000

This fixes radeonfb to not truncate 64 bits resources on 32 bits
platforms. Unfortunately, there are still issues with addresses
returned to userspace via struct fb_fix_screeninfo. This will
have to be dealt with separately.
