* 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: (27 commits)
PCI: Don't use dmi_name_in_vendors in quirk
PCI: remove unused AER functions
PCI/sysfs: move bus cpuaffinity to class dev_attrs
PCI: add rescan to /sys/.../pci_bus/.../
PCI: update bridge resources to get more big ranges when allocating space (again)
KVM: Use pci_store/load_saved_state() around VM device usage
PCI: Add interfaces to store and load the device saved state
PCI: Track the size of each saved capability data area
PCI/e1000e: Add and use pci_disable_link_state_locked()
x86/PCI: derive pcibios_last_bus from ACPI MCFG
PCI: add latency tolerance reporting enable/disable support
PCI: add OBFF enable/disable support
PCI: add ID-based ordering enable/disable support
PCI hotplug: acpiphp: assume device is in state D0 after powering on a slot.
PCI: Set PCIE maxpayload for card during hotplug insertion
PCI/ACPI: Report _OSC control mask returned on failure to get control
x86/PCI: irq and pci_ids patch for Intel Panther Point DeviceIDs
PCI: handle positive error codes
PCI: check pci_vpd_pci22_wait() return
