Sorry, I have some half-written review comments that I will clean up and send shortly. As commented on prior versions, I'd very much like to see the MCOUNT_ADDR hack go, by teaching the core ftrace code to not assume that an mcount symbol exists. We should be able to do that by separating the notion of NOPing a patch site from the notion of initializing it for the first time. Thanks, Mark.
