ARM ftrace function graph tracing support

Russell,

These are the function graph tracing patches posted to the list a couple of weeks ago (and the versatile sched_clock() notrace patch). I'm trying to get this to you via a pull request instead of putting them in the patch system because I'd like to preserve Tim's Author: line on one of the patches.

Please pull or let me know if you'd like this done differently, thanks.
