Any interrupt mapping should serve one interrupt domain
only. For a PCI bus, that bus is that domain, so all
bus#s in the interrupt-map should be identical.
Now you can cheat and have one interrupt-map handle
mappings for several PCI busses (in the same PCI domain).
Whenever this works at all, it is not by design, and
results in a huge mess and various (little) problems.
Just don't :-)
