Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6 

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6:
  x86/PCI: truncate _CRS windows with _LEN > _MAX - _MIN + 1
  x86/PCI: for host bridge address space collisions, show conflicting resource
  frv/PCI: remove redundant warnings
  x86/PCI: remove redundant warnings
  PCI: don't say we claimed a resource if we failed
  PCI quirk: Disable MSI on VIA K8T890 systems
  PCI quirk: RS780/RS880: work around missing MSI initialization
  PCI quirk: only apply CX700 PCI bus parking quirk if external VT6212L is present
  PCI: complain about devices that seem to be broken
  PCI: print resources consistently with %pR
  PCI: make disabled window printk style match the enabled ones
  PCI: break out primary/secondary/subordinate for readability
  PCI: for address space collisions, show conflicting resource
  resources: add interfaces that return conflict information
  PCI: cleanup error return for pcix get and set mmrbc functions
  PCI: fix access of PCI_X_CMD by pcix get and set mmrbc functions
  PCI: kill off pci_register_set_vga_state() symbol export.
  PCI: fix return value from pcix_get_max_mmrbc()
