[PATCH AUTOSEL 6.2 05/16] s390/virtio: sort out physical vs virtual pointers usage
...mmit 5fc5b94a273655128159186c87662105db8afeb5 ]
This does not fix a real bug, since virtual addresses
are currently indentical to physical ones.

[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.
* Protected Virtualization (PV):
Protected Virtualization guarantees, that non-shared memory of a guest
