Since it was indicated that introducing specific new vCPU ops may be
beneficial independent of the introduction of a fully physical-
address-based ABI flavor, here we go. There continue to be a few open
questions throughout the series, resolving of which was one of the main
goals of the earlier postings.
v5 adds one vm-fork specific pre-patch that does simply the introduced
code later on. It does also fix a vm-fork bug.
Patches 1 and 6 are missing and Ack from the mem-sharing maintainer.
Whole series will need a Release-Ack.
Thanks, Roger.
