Thanks Rick for your reply. Unfortunately I'm in the big bad corporate 
world where a simple minion such as myself is not granted sudo access. 
I've tried passing the callgraph (-g) flag to perf, however I can only 
recover the call stack within the kernel, it begins at what I suspect is 
the kernel entry point. Ideally I could generate a complete call stack.
