I'm not merging half-baked support. Not supporting nested LAM _may_ be ok, because KVM can _prevent_ exposing LAM to L2. I say "may" because I would still _very_ strongly prefer that nested support be added in the initial series. But omitting architectural interactions just because is not going to happen.
