Hasn't been discussed---as always, showing the code would be the best 
way to start a discussion. :)

However, note that the TDP MMU does not need an rmap at all.  Since that 
one is getting ready to become the default, the benefits of working on 
the rmap would be quite small and only affect nested virtualization.
