    Pull perf updates from Ingo Molnar:
     "Features:
    
       - Add "uretprobes" - an optimization to uprobes, like kretprobes are
         an optimization to kprobes.  "perf probe -x file sym%return" now
         works like kretprobes.  By Oleg Nesterov.
    
       - Introduce per core aggregation in 'perf stat', from Stephane
         Eranian.
    
       - Add memory profiling via PEBS, from Stephane Eranian.
    
       - Event group view for 'annotate' in --stdio, --tui and --gtk, from
         Namhyung Kim.
    
       - Add support for AMD NB and L2I "uncore" counters, by Jacob Shin.
    
       - Add Ivy Bridge-EP uncore support, by Zheng Yan
    
       - IBM zEnterprise EC12 oprofile support patchlet from Robert Richter.
    
       - Add perf test entries for checking breakpoint overflow signal
         handler issues, from Jiri Olsa.
    
       - Add perf test entry for for checking number of EXIT events, from
         Namhyung Kim.
    
       - Add perf test entries for checking --cpu in record and stat, from
         Jiri Olsa.
    
       - Introduce perf stat --repeat forever, from Frederik Deweerdt.
    
       - Add --no-demangle to report/top, from Namhyung Kim.
    
       - PowerPC fixes plus a couple of cleanups/optimizations in uprobes
         and trace_uprobes, by Oleg Nesterov.
    
      Various fixes and refactorings:
    
       - Fix dependency of the python binding wrt libtraceevent, from
         Naohiro Aota.
    
       - Simplify some perf_evlist methods and to allow 'stat' to share code
         with 'record' and 'trace', by Arnaldo Carvalho de Melo.
    
       - Remove dead code in related to libtraceevent integration, from
         Namhyung Kim.
    
       - Revert "perf sched: Handle PERF_RECORD_EXIT events" to get 'perf
         sched lat' back working, by Arnaldo Carvalho de Melo
    
       - We don't use Newt anymore, just plain libslang, by Arnaldo Carvalho
         de Melo.
    
       - Kill a bunch of die() calls, from Namhyung Kim.
    
       - Fix build on non-glibc systems due to libio.h absence, from Cody P
         Schafer.
    
       - Remove some perf_session and tracing dead code, from David Ahern.
    
       - Honor parallel jobs, fix from Borislav Petkov
    
       - Introduce tools/lib/lk library, initially just removing duplication
         among tools/perf and tools/vm.  from Borislav Petkov
    
      ... and many more I missed to list, see the shortlog and git log for
      more details."
