ACPI requires to run acpi_pci_{add|remove}_bus while new PCI bus is created. This allows to do some ACPI-specific additional configuration, like PCI hotplug slot enumeration. In order to fulfill these requirements, we implement arch-specific pcibios_{add|remove}_bus calls and call acpi_pci_{add|remove}_bus from there.

Is there a reason why this has to be a standalone patch ?
It is pretty much useless without patch 9 or I have stared at this series for too long.
