  PCI: use _CRS for PCI resource allocation
  PCI: avoid P2P prefetch window for expansion ROMs
  PCI: skip ISA ioresource alignment on some systems
  PCI: remove transparent bridge sizing
  pci: write file size to inode on proc bus file write
  pci: use size stored in proc_dir_entry for proc bus files
  pci: implement "pci=noaer"
  PCI: fix IDE legacy mode resources
  MSI: Use correct data offset for 32-bit MSI in read_msi_msg()
  PCI: Fix incorrect argument order to list_add_tail() in PCI dynamic ID code
  PCI: i386: Compaq EVO N800c needs PCI bus renumbering
  PCI: Remove no longer correct documentation regarding MSI vector assignment
  PCI: re-enable onboard sound on "MSI K8T Neo2-FIR"
  PCI: quirk_vt82c586_acpi: Omit reading PCI revision ID
  PCI: quirk amd_8131_mmrbc: Omit reading pci revision ID
  cpqphp: Use PCI_CLASS_REVISION instead of PCI_REVISION_ID for read
