    Actually I reordered that patch applying sequence.

    PCI, ACPI: Add acpi_pci_root_rescan()
    x86, PCI: Add arch version pci_root_rescan()
    PCI: Add /sys/bus/pci/rescan_root

    will be applied at last. So Jesse could skip those 3 or so patches,
    and upstream will only support really physical root-bus hotplug that
    user need to press attention button.
