Pull ftrace trampoline accounting fixes from Steven Rostedt:
 "Adding the new code for 3.19, I discovered a couple of minor bugs with
  the accounting of the ftrace_ops trampoline logic.

  One was that the old hash was not updated before calling the modify
  code for an ftrace_ops.  The second bug was what let the first bug go
  unnoticed, as the update would check the current hash for all
  ftrace_ops (where it should only check the old hash for modified
  ones).  This let things work when only one ftrace_ops was registered
  to a function, but could break if more than one was registered
  depending on the order of the look ups.

  The worse thing that can happen if this bug triggers is that the
  ftrace self checks would find an anomaly and shut itself down"
