    Pull tracing updates from Steven Rostedt:
     "No new features this release. Mostly clean ups, restructuring and
      documentation.
    
       - Have ftrace_bug() show ftrace errors before the WARN, as the WARN
         will reboot the box before the error messages are printed if
         panic_on_warn is set.
    
       - Have traceoff_on_warn disable tracing sooner (before prints)
    
       - Write a message to the trace buffer that its being disabled when
         disable_trace_on_warning() is set.
    
       - Separate out synthetic events from histogram code to let it be used
         by other parts of the kernel.
    
       - More documentation on histogram design.
    
       - Other small fixes and clean ups"
