Hi Steve,

I just moved from -rc6 to -rc7, and I noticed that the function-graph
tracer suddenly stopped working properly:  I do not see any output from
seeming most things except a handful of interrupt related events.  I
currently believe it may be an issue with tracing modules.

I haven't had a chance to bisect yet, but I did confirm that reverting
the -rc7 merge restores the previous tracer behavior.  Any help/pointers
appreciated.

Kind Regards,
-Greg
