Rusty, I can't find the actual patches, could you verify that they were
indeed sent?

By separating ISR, NOTIFY and COMMON we can place ISR and NOTIFY in PIO
and COMMON in MMIO. This gives us the benefit of having the small data
path use fast PIO, while big config path can use MMIO.

BIR is a concept from the PCI spec, but it was only used for MSI-X. I
don't expect to see it all around the kernel source.
