Pull virtio fixes from Michael S. Tsirkin:
 "Here are some virtio fixes for 3.4: a test build fix, a patch by Ren
  fixing naming for systems with a massive number of virtio blk devices,
  and balloon fixes for powerpc by David Gibson.

  There was some discussion about Ren's patch for virtio disc naming:
  some people wanted to move the legacy name mangling function to the
  block core.  But there's no concensus on that yet, and we can always
  deduplicate later.  Added comments in the hope that this will stop
  people from copying this legacy naming scheme into future drivers."
