Hi,
the following patches are for Linux running as a guest under a
host with virtio-ccw support.
Patch 1 makes the kvm_virtio driver exit gracefully if the page
containing s390-virtio information it expects is not present; it
could probably go in seperately from the other patches.
Patch 2 exports a needed interface.
Patch 3 adds a driver handling virtio-ccw devices. The virtual
subchannels have ccw devices with a special CU id this driver
matches for. The virtio_ccw driver handles configuration and
operation via the special new channel commands.
Patch 4 is a split out of common code.
Cornelia Huck (4):
s390/kvm: Handle hosts not supporting s390-virtio.
s390: Add a mechanism to get the subchannel id.
s390/kvm: Add a channel I/O based virtio transport driver.
s390/kvm: Split out early console code.
