This last one introduces a compile failure; fixup patch below.

Cheers,

Subject: [PATCH] virtio: Fix compile error

Include virtio_config.h to fix:

  drivers/virtio/virtio_ring.c: In function ‘vring_transport_features’:
  drivers/virtio/virtio_ring.c:331: error: ‘VIRTIO_TRANSPORT_F_START’ undeclared (first use in this function)
  drivers/virtio/virtio_ring.c:331: error: (Each undeclared identifier is reported only once
  drivers/virtio/virtio_ring.c:331: error: for each function it appears in.)
  drivers/virtio/virtio_ring.c:331: error: ‘VIRTIO_TRANSPORT_F_END’ undeclared (first use in this function)
  make[1]: *** [drivers/virtio/virtio_ring.o] Error 1
  make: *** [drivers/virtio/] Error 2

The include is added by a later patch in Rusty's queue
which wasn't submitted, hence it only coming to light
now.
