I found out that the tracer got stuck on ppc32 platforms because some early
functions call _mcount before mcount_enabled is initialized at all. I made a
patch, which marks these functions as notrace to solve this problem. With this
patch I can successfully boot up our mpc5200b platform and make latency trace.
(tested with -b switch in cyclictest). Please comment.

I made my patch against the -rt2 tree since the dummy call early_printk() in
-rt3 conflicts with our implementation of a functional early_printk(). It
should also work with -rt3 though.

Thanks, applied.

But for future reference, if you attach your patch please name it with the
ending of .patch and not .diff. Also do it at a -p1 level and not -p0.
