This code is transport agnostic and can be used by both the legacy
virtio code and virtio_ccw.

Add a driver for kvm guests that matches virtual ccw devices provided
by the host as virtio bridge devices.
These virtio-ccw devices use a special set of channel commands in order
to perform virtio functions.

There's no need to keep __MAX_SUBCHANNEL and __MAX_SSID private to the
common I/O layer when __MAX_CSSID is usable by everybody.

kvm will need to use some css-related structures (pmcw, schib, orb),
so let's move the definitions from drivers/s390/cio/ to include/asm/.

This patch enables using both virtio-xxx-s390 and virtio-xxx-ccw
by making the alias lookup code verify that a driver is actually
registered.
(Only included in order to allow testing of virtio-ccw; should be
replaced by cleaning up the virtio bus model.)

Hi,
I have incorporated the feedback I received to my first RFC for
virtio-ccw (http://marc.info/?l=kvm&m=134435141402140&w=2) and will
post the updates shortly.
Patches will again be sorted into kernel host and guest, qemu, and
virtio spec.
Feedback is still welcome.
