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: (27 commits) PCI: Don't use dmi_name_in_vendors in quirk PCI: remove unused AER functions PCI/sysfs: move bus cpuaffinity to class dev_attrs PCI: add rescan to /sys/.../pci_bus/.../ PCI: update bridge resources to get more big ranges when allocating space (again) KVM: Use pci_store/load_saved_state() around VM device usage PCI: Add interfaces to store and load the device saved state PCI: Track the size of each saved capability data area PCI/e1000e: Add and use pci_disable_link_state_locked() x86/PCI: derive pcibios_last_bus from ACPI MCFG PCI: add latency tolerance reporting enable/disable support PCI: add OBFF enable/disable support PCI: add ID-based ordering enable/disable support PCI hotplug: acpiphp: assume device is in state D0 after powering on a slot. PCI: Set PCIE maxpayload for card during hotplug insertion PCI/ACPI: Report _OSC control mask returned on failure to get control x86/PCI: irq and pci_ids patch for Intel Panther Point DeviceIDs PCI: handle positive error codes PCI: check pci_vpd_pci22_wait() return PCI: Use ICH6_GPIO_EN in ich6_lpc_acpi_gpio ... Fix up trivial conflicts in include/linux/pci_ids.h: commit a6e5e2be4461 moved the intel SMBUS ID definitons to the i2c-i801.c driver.
