Linus Torvalds 7639dad93a Three more changes.
1) I forgot that I had another selftest to stress test the ftrace
    instance creation. It was actually suppose to go into the 4.6
    merge window, but I never committed it. I almost forgot about it
    again, but noticed it was missing from your tree.
 
 2) Soumya PN sent me a clean up patch to not disable interrupts when
    taking the tasklist_lock for read, as it's unnecessary because
    that lock is never taken for write in irq context.
 
 3) Newer gcc's can cause the jump in the function_graph code to the
    global ftrace_stub label to be a short jump instead of a long one.
    As that jump is dynamically converted to jump to the trace code to
    do function graph tracing, and that conversion expects a long jump
    it can corrupt the ftrace_stub itself (it's directly after that call).
    One way to prevent gcc from using a short jump is to declare the
    ftrace_stub as a weak function, which we do here to keep gcc from
    optimizing too much.
