The patch changes the variable name for function find_pci_host_bridge()
so that it looks more meaningful. More specificly, the "bus" has been
replaced with "root_bus".

I don't understand the point of patches 1-3:

  pci: change variable name for find_pci_host_bridge
  pci: argument pci_bus for find_pci_host_bridge
  pci: fiddle with conversion of pci and CPU address

As far as I can tell, they don't have anything to do with patches 4-8.

I don't mind considering them later if they make things easier to read
or if they enable some other rework, but right now I want to make
progress on the P2P window alignment stuff, and patches 1-3 seem to be
distractions from that.
