I think it may be best for me to remove the two x86 specific patches, and
rebuild the ftrace work on top of it. For testing, I'll just keep those two
patches in my tree locally, but then I can get this moving for this merge
window.

Next merge window, we can spend more time on getting the perf API working
properly.
