Why did you collapse these two series into one at this point?

Last I was keeping up with - there was a -v9 00/23 series related to
bus_num and a -v2 00/11 series for pci_host_bridge related cleanup.

As a distro maintainer I need to try and keep up with what is occurring
here and actions like this - coalescing multiple series - unnecessarily
complicates things.  It also masks the fact that the bus_num series is
now on -v10 within a very short time frame (which implies a lot).
