    Pull ftrace fix from Steven Rostedt:
     "While rewriting the function probe code, I stumbled over a long
      standing bug. This bug has been there sinc function tracing was added
      way back when. But my new development depends on this bug being fixed,
      and it should be fixed regardless as it causes ftrace to disable
      itself when triggered, and a reboot is required to enable it again.
    
      The bug is that the function probe does not disable itself properly if
      there's another probe of its type still enabled. For example:
    
         # cd /sys/kernel/debug/tracing
         # echo schedule:traceoff > set_ftrace_filter
         # echo do_IRQ:traceoff > set_ftrace_filter
         # echo \!do_IRQ:traceoff > /debug/tracing/set_ftrace_filter
         # echo do_IRQ:traceoff > set_ftrace_filter
    
      The above registers two traceoff probes (one for schedule and one for
      do_IRQ, and then removes do_IRQ.
    
      But since there still exists one for schedule, it is not done
      properly. When adding do_IRQ back, the breakage in the accounting is
      noticed by the ftrace self tests, and it causes a warning and disables
      ftrace"
