Hm, your pull request mail was cut short as it ends here abruptly. I figured it 
out nevertheless, from the commit log:

====================>

User visible changes:

  - Force period term to overload global settings, i.e. previously this
    command line:

     $ perf record -e 'cpu/instructions,period=20000/',cycles -c 1000 sleep 1

    would result in both events having a period equal to 1000, with the fix we
    get something saner:

     $ perf evlist -v | grep period
     cpu/instructions,period=20000/: ... { sample_period, sample_freq }: 20000, ...
     cycles: ... { sample_period, sample_freq }: 1000 ...
     $

   (Jiri Olsa)

Infrastructure changes:

  - Use the dummy software event with freq=0 in the twatch.py python
    binding example, to avoid disabling nohz. (Arnaldo Carvalho de Melo)

  - Add some missing constants to the python binding. (Arnaldo Carvalho de Melo)

  - Fix mismatched declarations for elf_getphdrnum, that happens
    only in the corner case where this function is not found on
    the system.  (Arnaldo Carvalho de Melo)

  - Add build test for having ending double slash. (Jiri Olsa)

  - Introduce callgraph_set for callgraph option. (Kan Liang)
