Pull tracing fixes from Steven Rostedt:
 "Running tests on other changes, the system locked up due to lots of
  warnings.  It was caused by the stack tracer triggering a warning
  about using rcu_dereference() when RCU was not watching.  This can
  happen due to the fact that the stack tracer uses the function tracer
  to check each function, and there are functions that may be called and
  traced when RCU stopped watching.  Namely when a function is called
  just before going idle or to userspace and after RCU stopped watching
  that current CPU.

  The first patch makes sure that RCU is watching when the stack tracer
  uses RCU.  The second patch is to make sure that the stack tracer does
  not get called by functions in NMI, as it's not NMI safe"

* tag 'trace-fixes-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  tracing: Do not allow stack_tracer to record stack in NMI
  tracing: Have stack tracer force RCU to be watching
