virtio: Virtio platform driver [PATCH 01/02] virtio: Break out lguest virtio code to virtio_lguest.c [PATCH 02/02] virtio: Add virtio platform driver These patches add a virtio platform driver to the Linux kernel. This platform driver has the same role as the virtio_pci driver, but instead of building on top of emulated PCI this driver is making use of the platform bus together with driver
