    Pull virtio/vhost updates from Michael Tsirkin:
     "New features, performance improvements, cleanups:
    
       - basic polling support for vhost
       - rework virtio to optionally use DMA API, fixing it on Xen
       - balloon stats gained a new entry
       - using the new napi_alloc_skb speeds up virtio net
       - virtio blk stats can now be read while another VCPU is busy
         inflating or deflating the balloon
    
      plus misc cleanups in various places"
