Same comment as for patch 10: If we leave this out of the pci_create_host_bridge argument but set it later, ?e interface becomes simpler for callers that don't have custom pci_host_bridge_ops. This would break your phb_prepare() callback, but I assume a host driver can just make a direct function call before entering pci_create_host_bridge for this. Let me know if I'm missing something here. Arnd
