Linus Torvalds 03fae44b41 With the new ORC unwinder, ftrace stack tracing became disfunctional.

One was that ORC didn't know how to handle the ftrace callbacks in general
 (which Josh fixed). The other was that ORC would just bail if it hit a
 dynamically allocated trampoline. Which means all ftrace stack tracing that
 happens from the function tracer would produce no results (that includes
 killing the max stack size tracer).  I added a check to the ORC unwinder to
 see if the trampoline belonged to ftrace, and if it did, use the orc entry
 of the static trampoline that was used to create the dynamic one (it would
 be identical).
 
 Finally, I noticed that the skip values of the stack tracing were out of
 whack. I went through and fixed them up.
