The above I added because they just made the function tracer output
quite ugly and bloated.  The lockdep got messing when it was debugging
the locks used in the tracer that was tracing lockdep. The above had
nothing to do with what kind of clock we used.  We added recursion
protection, but it was still producing ugly output.
