[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a
way that I think makes more sense. The vast majority of the credit
for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.
