[PATCH] x86_64: Implement early DMI scanning
There are more and more cases where we need to know DMI information early to work around bugs. i386 already had early DMI scanning, but x86-64 didn't. Implement this now. This required some cleanup in the i386 code. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
