That's what

[PATCH RFC v7 00/14] vhost: ring format independence
This intentionally leaves "fixup" changes separate - hopefully
that is enough to fix vhost-net crashes reported here,
but it helps me keep track of what changed.
I will naturally squash them later when we are done.
This adds infrastructure required for supporting
multiple ring formats.
The idea is as follows: we convert descriptors to an
independent format first, and process that
