I made a few changes, the most important being to call pcie_bus_configure_settings() before pci_bus_add_devices(), because drivers may claim devices in pci_bus_add_devices(), and the PCI core shouldn't touch devices after drivers claim them. I dropped the acks and tested-by because of that change, but I'll happily add them back if Lorenzo and Pavel confirm. The patches are here if you want to review/test them: https://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/log/?h=pci/enumeration I'm sure the other patches on that branch will need some tweaks, too, so I don't have any problem with updating these.
