Well, I was promised someome else was going to carry all this, also,
while you're all having fun playing with this, I've not yet had answers
to the important questions of how L1TF complete we want to be and if all

Also, I still don't see this stuff working for high context switch rate
workloads, and that is exactly what some people were aiming for..
