Prevent IDE boot ops on NUMA system Without this patch a Opteron test system here oopses at boot with current git. Calling to_pci_dev() on a NULL pointer gives a negative value so the following NULL pointer check never triggers and then an illegal address is referenced. Check the unadjusted original device pointer for NULL instead. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
