NAK to adding any KVM-handled hypercall, and probably NAK to any approach that
requires KVM changes.

With regard to timing, please show a little patience and awareness.  It's Monday.
You posted a fairly large series on a Thursday, during a merge window.  If you
change direction after ~2 days for a series of this natures (touchs multiple
subsystems and introduces guest/host ABI), you're likely going to end up with
severe whiplash.
