Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/pci-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/pci-2.6: (64 commits) PCI: make pci_bus a struct device PCI: fix codingstyle issues in include/linux/pci.h PCI: fix codingstyle issues in drivers/pci/pci.h PCI: PCIE ASPM support PCI: Fix fakephp deadlock PCI: modify SB700 SATA MSI quirk PCI: Run ACPI _OSC method on root bridges only PCI ACPI: AER driver should only register PCIe devices with _OSC PCI ACPI: Added a function to register _OSC with only PCIe devices. PCI: constify function pointer tables PCI: Convert drivers/pci/proc.c to use unlocked_ioctl pciehp: block new requests from the device before power off pciehp: workaround against Bad DLLP during power off pciehp: wait for 1000ms before LED operation after power off PCI: Remove pci_enable_device_bars() from documentation PCI: Remove pci_enable_device_bars() PCI: Remove users of pci_enable_device_bars() PCI: Add pci_enable_device_{io,mem} intefaces PCI: avoid save the same type of cap multiple times PCI: correctly initialize a structure for pcie_save_pcix_state() ...
