* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6:
  PCI: Limit VPD length for Broadcom 5708S
  PCI PM: Export pci_pme_active to drivers
  PCI: remove duplicate symbol from pci_ids.h
  PCI: check the return value of device_create_bin_file() in pci_create_bus()
  PCI: fully restore MSI state at resume time
  DMA: make dma-coherent.c documentation kdoc-friendly
  PCI: make pci_register_driver() a macro
  PCI: add Broadcom 5708S to VPD length quirk
