[PATCH] x86_64: Don't oops at boot when empty Opteron node has IO The code to detect IO links on Opteron would not check if the node had actually memory. This could lead to pci_bus_to_node returning an invalid node, which might cause crashes later when dma_alloc_coherent passes it to page_alloc_node(). The bug has been there forever but for some reason it is causing now crashes. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
