thanks very much!

I have read your test script, which seems only test the static function
tracer, not include the "dynamic function tracer" and "function graph
tracer". since both of them are ported to mips.

currently, "dynamic function tracer" works well, but "function graph
tracer" maybe crash for some NMI exceptions, need to be fixed later.
