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.
