[PATCH RFC 00/11] linux: towards virtio-1 guest support
This patchset tries to go towards implementing both virtio-1 compliant and
transitional virtio drivers in Linux. Branch available at
git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux virtio-1
This is based on some old patches by Rusty to handle extended feature bits
and endianness conversions. Thomas implemented the new virtio-ccw transport
revision command, and I hacked up some

[PATCH 00/10] s390: virtio: support protected virtualization
Enhanced virtualization protection technology may require the use of
bounce buffers for I/O. While support for this was built into the virtio
core, virtio-ccw wasn't changed accordingly.
Some background on technology (not part of this series) and the
terminology used.
