Personally I think the approach is ugly, and also you have not yet presented
evidence that supporting the Viridian paravirtualisations improves
performance. If it doesn't then it's a waste of time; if it does then it
raises the question of which hypercalls provide the benefit, and do we get a
smaller neater patch by supporting just those? One final comment is that the
TLB management code that this slaps on top of the core hypervisor looks a
bit scary to me. Tim Deegan may care to comment more on that.
