Can you test this patch. It makes the default operation of calling the
function graph tracer trampoline directly being disabled. It is now up
to the arch to define FTRACE_GRAPH_TRAMP_ADDR that can be used to call
directly. If it is not set, the old method of calling the function
tracer first is used.

I'll worked on getting arm to be called directly too. Can you test that
patch as well? I'll reply to this email with that one.

Thanks!
