Hmm, we do have a way to retrieve the actual return caller from a location
for return_to_handler:

  See kernel/trace/fgraph.c: ftrace_graph_get_ret_stack()

Hmm, I think the x86 ORC unwinder needs to use this.  

I'm confused, is that not what ftrace_graph_ret_addr() already does?

Ah yeah, that does it too. I just searched for the first function that did
the look up ;-)

Now I guess the question is, why is this not working?
