I probably wouldn't worry about it too much. If anything all this
patch is doing is disabling relaxed ordering on the platforms we know
have issues based on what Casey originally had. If nothing else we can
follow up once the patches are in the kernel and if somebody has an
issue then.

You can include my acked-by, but it is mostly related to how this
interacts with NICs, and not so much about the PCI chipsets
themselves.
