Suspicious, but I hopefully won't forget to comment on this when
reaching the actual patch.

In any event, I think you continue to send this series to an
incomplete list of people (possibly because you didn't update it
after the initial version): Both SVM and VMX have one more
maintainer than you Cc (Aravind and Eddie respectively; oddly
enough you send the patch directly to two of the others).
