[PATCH v3 0/8] 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.
* Protected Virtualization (PV):
Protected Virtualization guarantees, that non-shared memory of a guest
that operates in PV
