Pull tracing fixes from Steven Rostedt:

 - Bring back context level recursive protection in ring buffer.

   The simpler counter protection failed, due to a path when tracing
   with trace_clock_global() as it could not be reentrant and depended
   on the ring buffer recursive protection to keep that from happening.

 - Prevent branch profiling when FORTIFY_SOURCE is enabled.

   It causes 50 - 60 MB in warning messages. Branch profiling should
   never be run on production systems, so there's no reason that it
   needs to be enabled with FORTIFY_SOURCE.
