Merge remote-tracking branch 'remotes/awilliam/tags/vfio-update-20141222.0' into staging

VFIO updates:
- Conversion to tracepoints (Eric Auger)
- Fix memory listener address space (Frank Blaschka)
- Move to hw/vfio/ and split common vs pci (Eric Auger & Kim Phillips)
- Trivial error_report() fixes (Alex Williamson)

In addition to enabling S390 with the address space fix and updating
to use tracepoints rather than compile time debug, this set of patches
moves hw/misc/vfio.c to hw/vfio/ and paves the way for vfio-platform
support by splitting common functionality from PCI specific code.
