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: AMD 813x B2 devices do not need boot interrupt quirk
PCI: Enable PCIe AER only after checking firmware support
PCI: pciehp: Handle interrupts that happen during initialization.
PCI: don't enable too many HT MSI mappings
PCI: add some sysfs ABI docs
PCI quirk: enable MSI on 8132
