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)
  x86: allocate space within a region top-down
  x86: update iomem_resource end based on CPU physical address capabilities
  x86/PCI: allocate space from the end of a region, not the beginning
  PCI: allocate bus resources from the top down
  resources: support allocating space within a region from the top down
  resources: handle overflow when aligning start of available area
  resources: ensure callback doesn't allocate outside available space
  resources: factor out resource_clip() to simplify find_resource()
  resources: add a default alignf to simplify find_resource()
  x86/PCI: MMCONFIG: fix region end calculation
  PCI: Add support for polling PME state on suspended legacy PCI devices
  PCI: Export some PCI PM functionality
  PCI: fix message typo
  PCI: log vendor/device ID always
  PCI: update Intel chipset names and defines
  PCI: use new ccflags variable in Makefile
  PCI: add PCI_MSIX_TABLE/PBA defines
  PCI: add PCI vendor id for STmicroelectronics
  x86/PCI: irq and pci_ids patch for Intel Patsburg DeviceIDs
  PCI: OLPC: Only enable PCI configuration type override on XO-1
