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 ...
