Pull PCI changes from Bjorn Helgaas:
 "Host bridge hotplug:
    - Add MMCONFIG support for hot-added host bridges (Jiang Liu)
  Device hotplug:
    - Move fixups from __init to __devinit (Sebastian Andrzej Siewior)
    - Call FINAL fixups for hot-added devices, too (Myron Stowe)
    - Factor out generic code for P2P bridge hot-add (Yinghai Lu)
    - Remove all functions in a slot, not just those with _EJx (Amos
      Kong)
  Dynamic resource management:
    - Track bus number allocation (struct resource tree per domain)
      (Yinghai Lu)
    - Make P2P bridge 1K I/O windows work with resource reassignment
      (Bjorn Helgaas, Yinghai Lu)
    - Disable decoding while updating 64-bit BARs (Bjorn Helgaas)
  Power management:
    - Add PCIe runtime D3cold support (Huang Ying)
  Virtualization:
    - Add VFIO infrastructure (ACS, DMA source ID quirks) (Alex
      Williamson)
    - Add quirks for devices with broken INTx masking (Jan Kiszka)
  Miscellaneous:
    - Fix some PCI Express capability version issues (Myron Stowe)
    - Factor out some arch code with a weak, generic, pcibios_setup()
      (Myron Stowe)"
