Since the complete series didn't get much feedback, I've begun to post smaller subsets in an effort to get them merged more easily. The first patch in this series converts the __init annotations for pci_common_init() (and pcibios_init_hw() because it is called from the former) to __devinit to make sure that they stay around after the init stage. This is required because the Tegra driver depends on regulators that become available only very late during boot and uses deferred probing to handle this situation. It turned out that this postpones the PCI bus initialization until after init, thus this patch. The second patch is used to pass per-controller or per-host-bridge data to the driver, such that it can be associated with the corresponding bus. This is also required by the Tegra driver in order to pass a driver-private structure to the PCI bus (or more precisely the pci_sys_data structure associated with a bus). It is subsequently used to obtain the root port private data given the corresponding PCI bus.
