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/PM: Report wakeup events before resuming devices
  PCI/PM: Use pm_wakeup_event() directly for reporting wakeup events
  PCI: sysfs: Update ROM to include default owner write access
  x86/PCI: make Broadcom CNB20LE driver EMBEDDED and EXPERIMENTAL
  x86/PCI: don't use native Broadcom CNB20LE driver when ACPI is available
  PCI/ACPI: Request _OSC control once for each root bridge (v3)
  PCI: enable pci=bfsort by default on future Dell systems
  PCI/PCIe: Clear Root PME Status bits early during system resume
  PCI: pci-stub: ignore zero-length id parameters
  x86/PCI: irq and pci_ids patch for Intel Patsburg
  PCI: Skip id checking if no id is passed
  PCI: fix __pci_device_probe kernel-doc warning
  PCI: make pci_restore_state return void
  PCI: Disable ASPM if BIOS asks us to
  PCI: Add mask bit definition for MSI-X table
  PCI: MSI: Move MSI-X entry definition to pci_regs.h

Fix up trivial conflicts in drivers/net/{skge.c,sky2.c} that had in the
meantime been converted to not use legacy PCI power management, and thus
no longer use pci_restore_state() at all (and that caused trivial
conflicts with the "make pci_restore_state return void" patch)

           Read the PCI windows out of the CNB20LE host bridge. This allows
