Merge branch 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6
* 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: PCI: remove printks about disabled bridge windows PCI: fold pci_calc_resource_flags() into decode_bar() PCI: treat mem BAR type "11" (reserved) as 32-bit, not 64-bit, BAR PCI: correct pcie_set_readrq write size PCI: pciehp: change wait time for valid configuration access x86/PCI: Preserve existing pci=bfsort whitelist for Dell systems PCI: ARI is a PCIe v2 feature x86/PCI: quirks: Use pci_dev->revision PCI: Make the struct pci_dev * argument of pci_fixup_irqs const. PCI hotplug: cpqphp: use pci_dev->vendor PCI hotplug: cpqphp: use pci_dev->subsystem_{vendor|device} x86/PCI: config space accessor functions should not ignore the segment argument PCI: Assign values to 'pci_obff_signal_type' enumeration constants x86/PCI: reduce severity of host bridge window conflict warnings PCI: enumerate the PCI device only removed out PCI hieratchy of OS when re-scanning PCI PCI: PCIe AER: add aer_recover_queue x86/PCI: select direct access mode for mmconfig option PCI hotplug: Rename is_ejectable which also exists in dock.c
