[PATCH] PCI: Fix dumb bug in mmconfig fix
Use correct address when referencing mmconfig aperture while checking for broken MCFG. This was a typo when porting the code from 64bit to 32bit. It caused oopses at boot on some ThinkPads. Should definitely go into 2.6.15. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
