Bug Description
Function tracer is the most important tracer of the ftrace, we need to enable this option for the further debugging.
And according to bug 570389, function profiler is very useful for the performance analysis, so please consider enable this option as well.

The DYNAMIC_FTRACE is not supported right now, so it will heavily affect the system performance if enable the ftrace.
