Andi Kleen was just asking me about the NMI CR3 handling and why we restore it unconditionally. I was *sure* we had documented it well. We did not. Add some documentation. We have common entry code where the CR3 value is stashed, but three places in two big code paths where we restore it. I put bulk of the comments in this common path and then refer to it from the other spots.
