Linus Torvalds f0691533b7 virtio/vhost: new features, performance improvements, cleanups
This adds basic polling support for vhost.
 Reworks 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
 us busy inflating or deflating the balloon.
 Plus misc cleanups in various places.
