For the smt case, can you make #AC enable a property of the process?
Then disable it on the core if either smt process requires it be disabled?
This would mean that is a 'mixed environment' not all split accesses
would actually generate #AC - but enough would to detect broken code
that doesn't have #AC explicitly disabled.
I'm not sure you'd want a guest to flip #AC enable based on the process
it is scheduling, but it might work for the base metal scheduler.
