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: only save/restore existent registers in the PCIe capability x86/PCI: don't bother with root quirks if _CRS is used docbooks: add/fix PCI kernel-doc PCI: cleanup debug output resources x86/PCI: set_pci_bus_resources_arch_default cleanups x86/PCI: Move set_pci_bus_resources_arch_default into arch/x86 x86/PCI: don't call e820_all_mapped with -1 in the mmconfig case PCI quirk: disable MSI on VIA VT3364 chipsets
