[PATCH] x86_64: Fix zero mcfg entry workaround on x86-64
I broke this earlier when moving the patch from i386 to x86-64. Need to return the virtual address here, not the physical address. This fixes some boot time crashes on x86-64. Cc: gregkh@suse.de Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
