[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.
