The main patch in this series changes the way we discover the downstream bus
number of PCI root bridges. The end result should be the same as the current
code (as far as I know, this doesn't fix any bugs). But I believe this
follows the intent of the spec better, makes Linux work more like Windows,
and removes false accusations Linux makes against the BIOS.
