Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6:
PCI: bus speed strings should be const
PCI hotplug: Fix build with CONFIG_ACPI unset
PCI: PCIe: Remove the port driver module exit routine
PCI: PCIe: Move PCIe PME code to the pcie directory
PCI: PCIe: Disable PCIe port services during port initialization
PCI: PCIe: Ask BIOS for control of all native services at once
ACPI/PCI: Negotiate _OSC control bits before requesting them
ACPI/PCI: Do not preserve _OSC control bits returned by a query
ACPI/PCI: Make acpi_pci_query_osc() return control bits
ACPI/PCI: Reorder checks in acpi_pci_osc_control_set()
PCI: PCIe: Introduce commad line switch for disabling port services
PCI: PCIe AER: Introduce pci_aer_available()
x86/PCI: only define pci_domain_nr if PCI and PCI_DOMAINS are set
PCI: provide stub pci_domain_nr function for !CONFIG_PCI configs
