There might actually be a case for making this modular, as the
virtio-pci transport can be built as a module as well. But I don't
think anybody really cares, and your patch is easily reverted should we
want to do this later, so

[going through the s390 tree with the other patches is probably easier
as taking this through the virtio tree]
