Merge branch 'pci/resource' into next

* pci/resource:
  PCI: Allocate 64-bit BARs above 4G when possible
  PCI: Enforce bus address limits in resource allocation
  PCI: Split out bridge window override of minimum allocation address
  agp/ati: Use PCI_COMMAND instead of hard-coded 4
  agp/intel: Use CPU physical address, not bus address, for ioremap()
  agp/intel: Use pci_bus_address() to get GTTADR bus address
  agp/intel: Use pci_bus_address() to get MMADR bus address
  agp/intel: Support 64-bit GMADR
  agp/intel: Rename gtt_bus_addr to gtt_phys_addr
  drm/i915: Rename gtt_bus_addr to gtt_phys_addr
  agp: Use pci_resource_start() to get CPU physical address for BAR
  agp: Support 64-bit APBASE
  PCI: Add pci_bus_address() to get bus address of a BAR
  PCI: Convert pcibios_resource_to_bus() to take a pci_bus, not a pci_dev
  PCI: Change pci_bus_region addresses to dma_addr_t
