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
PCI hotplug to work on systems with the CNB20LE chipset which do
not have ACPI.
