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: label: remove #include of ACPI header to avoid warnings PCI: label: Fix compilation error when CONFIG_ACPI is unset PCI: pre-allocate additional resources to devices only after successful allocation of essential resources. PCI: introduce reset_resource() PCI: data structure agnostic free list function PCI: refactor io size calculation code PCI: do not create quirk I/O regions below PCIBIOS_MIN_IO for ICH PCI hotplug: acpiphp: set current_state to D0 in register_slot PCI: Export ACPI _DSM provided firmware instance number and string name to sysfs PCI: add more checking to ICH region quirks PCI: aer-inject: Override PCIe AER Mask Registers PCI: fix tlan build when CONFIG_PCI is not enabled PCI: remove quirk for pre-production systems PCI: Avoid potential NULL pointer dereference in pci_scan_bridge PCI/lpc: irq and pci_ids patch for Intel DH89xxCC DeviceIDs PCI: sysfs: Fix failure path for addition of "vpd" attribute
