    Linus Torvalds authored
    Pull tracing updates from Steven Rostedt:
     "Nothing major this round.  Mostly small clean ups and fixes.
      Some visible changes:
       - A new flag was added to distinguish traces done in NMI context.
       - Preempt tracer now shows functions where preemption is disabled but
         interrupts are still enabled.
      Other notes:
       - Updates were done to function tracing to allow better performance
         with perf.
       - Infrastructure code has been added to allow for a new histogram
         feature for recording live trace event histograms that can be
         configured by simple user commands.  The feature itself was just
         finished, but needs a round in linux-next before being pulled.
         This only includes some infrastructure changes that will be needed"
