Halil Pasic 37db8985b2 s390/cio: add basic protected virtualization support ... As virtio-ccw devices are channel devices, we need to use the dma area within the common I/O layer for any communication with the hypervisor. Note that we do not need to use that area for control blocks directly referenced by instructions, e.g. the orb. It handles neither QDIO in the common code, nor any device type specific stuff (like channel programs constructed by the DASD driver). An interesting side effect is that virtio structures are now going to get allocated in 31 bit addressable storage.
