We've been talking about this inside Intel. Suffice to say that DOITM was not designed to be turned on all the time. If software turns it on all the time, it won't accomplish what it was designed to do. The _most_ likely thing that's going to happen is that DOITM gets redefined to be much more limited in scope. The current DOITM architecture is very broad, but the implementations have much more limited effects. This means that the architecture can probably be constrained and still match the hardware that's out there today. That's pure speculation (ha!) on my part. I think we should hold off on merging any DOITM patches until the dust settles. As far as I know, there is no pressing practical reason to apply something urgently. Any objections?
