[RFC 0/2] virtio_pci: patches never to apply.

This should allow testing when QEMU gets VIRTIO_PCI_CAP_PCI_CFG support,
but I'm pretty sure we should never allow these patches upstream.

Tested with lguest (in virtio-next), which supports VIRTIO_PCI_CAP_PCI_CFG.

Rusty Russell (2):
  virtio_pci: abstract all MMIO accesses.
  virtio: Introducing virtio_pci.no_mmio, the worst boot option in
    history.
