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:
  PCIe AER: prevent AER injection if hardware masks error reporting
  PCI/PM: Use per-device D3 delays
  PCI: Check the node argument passed to cpumask_of_node
  PCI: AER: fix aer inject result in kernel oops
  PCI: pcie portdrv: style cleanup
