Right. I leave things on topic branches for a day or two to give a chance for Fengguang's auto-builder to find problems before I merge them into the more public "next" or "for-linus" branches. > > Yinghai pointed out a problem with this one, so I omitted it: > > > > PCI: Assign unassigned bus resources in pci_scan_root_bus() > > Thats fine, host bridge drivers will have to work around pci_scan_root_bus() reduced > functionality for now. Well, it's not really "reduced functionality." It is unchanged by this series and host bridge drivers can continue using it the same way they have in the past. It's just that we'd like to make it smarter someday. > > I added this one to my pci/host-generic branch: > > > > PCI: Add pci_remap_iospace() to map bus I/O resources > > > > I assume this depends on the pci_scan_root_bus() change (if not, let me > > know), so I omitted this one: > > > > arm64: Add architectural support for PCI > > No, there is no dependency there on pci_scan_root_bus(), it can go in the series. > The only thing that depends on a feature rich pci_scan_root_bus() is the host > bridge driver in order to be able to use only one line to process the root bus. OK, I rebuilt pci/host-generic from scratch. It consists of your v13 patches + Arnd's build fix for pci_pio_to_address() in !CONFIG_OF configs.
