Subject: [PATCH 0/3] virtio DMA API core stuff

This switches virtio to use the DMA API unconditionally.  I'm sure
it breaks things, but it seems to work on x86 using virtio-pci, with
and without Xen, and using both the modern 1.0 variant and the
legacy variant.

Andy Lutomirski (3):
  virtio_net: Stop doing DMA from the stack
  virtio_ring: Support DMA APIs
  virtio_pci: Use the DMA API
