Sure. I think that FTRACE config is borderline fine, although I think
tracing is pretty different from the debug options that don't need the
user to actually do anything (like PAGEALLOC_DEBUG).
It's the other ones I think were clearly dubious (ok, the MARKERS one
isn't "clearly" dubious, since I have no idea why it got enabled, so I
guess it would count as "unclearly dubious" then).
