Pull PCI changes from Bjorn Helgaas:
 "Host bridge hotplug
    - Protect acpi_pci_drivers and acpi_pci_roots (Taku Izumi)
    - Clear host bridge resource info to avoid issue when releasing
      (Yinghai Lu)
    - Notify acpi_pci_drivers when hot-plugging host bridges (Jiang Liu)
    - Use standard list ops for acpi_pci_drivers (Jiang Liu)

  Device hotplug
    - Use pci_get_domain_bus_and_slot() to close hotplug races (Jiang
      Liu)
    - Remove fakephp driver (Bjorn Helgaas)
    - Fix VGA ref count in hotplug remove path (Yinghai Lu)
    - Allow acpiphp to handle PCIe ports without native hotplug (Jiang
      Liu)
    - Implement resume regardless of pciehp_force param (Oliver Neukum)
    - Make pci_fixup_irqs() work after init (Thierry Reding)

  Miscellaneous
    - Add pci_pcie_type(dev) and remove pci_dev.pcie_type (Yijing Wang)
    - Factor out PCI Express Capability accessors (Jiang Liu)
    - Add pcibios_window_alignment() so powerpc EEH can use generic
      resource assignment (Gavin Shan)
    - Make pci_error_handlers const (Stephen Hemminger)
    - Cleanup drivers/pci/remove.c (Bjorn Helgaas)
    - Improve Vendor-Specific Extended Capability support (Bjorn
      Helgaas)
    - Use standard list ops for bus->devices (Bjorn Helgaas)
    - Avoid kmalloc in pci_get_subsys() and pci_get_class() (Feng Tang)
    - Reassign invalid bus number ranges (Intel DP43BF workaround)
      (Yinghai Lu)"
