Moreover ARM64 is going to do the same. So it seams that acpi_pci_{add|remove}_bus is generic enough to be default option for pcibios_{add|remove}_bus hooks. Also, it is always safe to run acpi_pci_{add|remove}_bus as they have empty stubs for !ACPI case and return if ACPI has been switched off in run time. After all we can remove x86 and ia64 pcibios_{add|remove}_bus implementation.
