  virtio_ccw: finalize_features error handling (2014-12-09 16:32:41 +0200)

Note: some net drivers are affected by these patches.
David said he's fine with merging these patches through
my tree.
Rusty's on vacation, he acked using my tree for these, too.

virtio: virtio 1.0 support, misc patches

This adds a lot of infrastructure for virtio 1.0 support.
Notable missing pieces: virtio pci, virtio balloon (needs spec extension),
vhost scsi.

Plus, there are some minor fixes in a couple of places.
