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)
