I just got back from a 3 month sabbatical so I am slowly getting back into the real world and how to be a computer engineer. Yes, I am not sure why someone would want to configure their kernel to load a PTI module when there is not one on the platform to begin with. So that is a configuration problem of a user. But I'll look at it and see if I think of anything; be a good exercise to re-jog my memory.
