Merge remote-tracking branch 'awilliam/tags/vfio-pci-for-qemu-20131010.0' into staging

vfio-pci updates include:
 - Forgotten MSI affinity patch posted several months ago
 - Lazy option ROM loading to delay load until after device/bus resets
 - Error reporting cleanups
 - PCI hot reset support introduced with Linux v3.12 development kernels
 - Debug build fix for int128

The lazy ROM loading and hot reset should help VGA assignment as we can
now do a bus reset when there are multiple devices on the bus, ex.
multi-function graphics and audio cards.
