I see there is also an infrastructure patch (by you) required for this
change: one to add pci_fixup_irqs_local(). I'll hold off on posting that
pending your answer to the question above.

No, this is not for upstream. The pci_fixup_irqs_local function was an RFC
that should be solved in a more generic way.
