 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.
