Great.

These changes should be dropped. We already have this model covered and
regenerating the data files for existing CPUs just causes unnecessary
and often unrelated changes.

While we don't have a special model Ryzen 9, we still want to have it
covered in the test suit to check we assign the appropriate model to it.

Anyway, more on this in my reply to the patch itself.

Thanks for the work so far.
