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

    Cheers,
    Mark.

    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.
