  * Improved messages when doing profiling in all or a subset of CPUs
    using a workload as the session delimitator, as in:

     'perf stat --cpu 0,2 sleep 10s'

    from Arnaldo Carvalho de Melo.

  * Add units to nanosec-based counters in 'perf stat', from David Ahern.

  * Fixes for some memory leaks, from Namhyumg Kim.

  * Fix srcline sort key behavior, from Namhyung Kim.

  * Fix failing assertions in numa bench, from Petr Holasek.

  * perf bash completion fixes and improvements from Ramkumar Ramachandra.
