* 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: (30 commits)
  PCI: update for owner removal from struct device_attribute
  PCI: Fix warnings when CONFIG_DMI unset
  PCI: Do not run NVidia quirks related to MSI with MSI disabled
  x86/PCI: use for_each_pci_dev()
  PCI: use for_each_pci_dev()
  PCI: MSI: Restore read_msi_msg_desc(); add get_cached_msi_msg_desc()
  PCI: export SMBIOS provided firmware instance and label to sysfs
  PCI: Allow read/write access to sysfs I/O port resources
  x86/PCI: use host bridge _CRS info on ASRock ALiveSATA2-GLAN
  PCI: remove unused HAVE_ARCH_PCI_SET_DMA_MAX_SEGMENT_{SIZE|BOUNDARY}
  PCI: disable mmio during bar sizing
  PCI: MSI: Remove unsafe and unnecessary hardware access
  PCI: Default PCIe ASPM control to on and require !EMBEDDED to disable
  PCI: kernel oops on access to pci proc file while hot-removal
  PCI: pci-sysfs: remove casts from void*
  ACPI: Disable ASPM if the platform won't provide _OSC control for PCIe
  PCI hotplug: make sure child bridges are enabled at hotplug time
  PCI hotplug: shpchp: Removed check for hotplug of display devices
  PCI hotplug: pciehp: Fixed return value sign for pciehp_unconfigure_device
  PCI: Don't enable aspm before drivers have had a chance to veto it
