              cd tools/perf/

         * 'perf report/top' enhancements:

            . Add --max-stack option to limit callchain stack scan in 'top'
              and 'report', improving callchain processing when reducing the

            . 'perf trace' now can can use a 'perf probe' dynamic tracepoints
              to hook into the userspace -> kernel pathname copy so that it
              can map fds to pathnames without reading /proc/pid/fd/ symlinks.
              From Arnaldo Carvalho de Melo.
      
            . Show VFS path associated with fd in live sessions, using a

            . 'perf trace' now emits hints as to why tracing is not possible,
              helping the user to setup the system to allow tracing in the
              desired permission granularity, telling if the problem is due to
              debugfs not being mounted or with not enough permission for
              !root, /proc/sys/kernel/perf_event_paranoit value, etc.  From

            . Address the root cause of that 'perf sched' stack initialization
              build slowdown, by programmatically setting a big array after
              moving the global variable back to the stack.  Fix from Adrian
              Hunter.

      Pull RCU updates from Ingo Molnar:
       "The main RCU changes in this cycle are:
      
         - Idle entry/exit changes, to throttle callback execution and other
           refinements to speed up kbuild, primarily to address performance
           issues located by Tibor Billes.
      
         - Grace-period related changes, primarily to aid in debugging,
           inspired by an -rt debugging session.
      
         - Code reorganization moving RCU's source files into its own
           kernel/rcu/ directory.
      
         - RCU documentation updates
      
         - Miscellaneous fixes.
