  vfio: Fix debug output for int128 values (2013-10-03 09:10:09 -0600)

----------------------------------------------------------------
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.  The known remaining part for
VGA is the KVM-VFIO device and matching QEMU support to properly handle
devices that make use of No-Snoop transactions, particularly on Intel
host systems.
