Hmm, I think it might be better to separate this from the dump_on_oops.
How about a ftrace_default_tracer parameter?

If one is defined, it is activated as soon as it is initialized. This way
we decouple the dump_on_oops, which we may not always want, and a way to
start tracers before the switch to user space.
