Add basic support for virtio with grants on x86 by defaulting the
backend to be in dom0 in the case the guest kernel was built with
CONFIG_XEN_VIRTIO_FORCE_GRANT.

Juergen Gross (3):
  xen/virtio: restructure xen grant dma setup
  xen/virtio: use dom0 as default backend for
    CONFIG_XEN_VIRTIO_FORCE_GRANT
  xen/virtio: enable grant based virtio on x86
