    Pull tracing fixes from Steven Rostedt:
     "A few updates and fixes:
    
       - move the suppressing of the __builtin_return_address >0 warning to
         the tracing directory only.
    
       - metag recordmcount fix for newer glibc's
    
       - two tracing histogram fixes that were reported by KASAN"
