[PATCH v6 0/6] drm/dp_mst: Improve VCPI helpers, use in nouveau
This patchset does some cleaning up of the atomic VCPI helpers for MST, and converts nouveau over to using them. I would have included amdgpu in this patch as well, but at the moment moving them over to the atomic helpers is nontrivial. [sorry for still not adding your R-Bs! I ended up needing to make a lot of changes to make it so we do actually kref() each port in the atomic state] Cc: Daniel

[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
