Subject: [PATCH v2 00/11] Python improvements for a real use of parse_events

While parse_events access in python was added, it wasn't used by any
python script. In enabling this for the tracepoint.py script a number
of latent bugs and necessary improvements were discovered.

v2: Fix a whitespace issue on the evlist.config patch spotted by
    Howard and add his reviewed-by tags.

Ian Rogers (11):
  perf debug: Avoid stack overflow in recursive error message
  perf evlist: Add success path to evlist__create_syswide_maps
  perf evsel: tp_format accessing improvements
  perf python: Add evlist enable and disable methods
  perf python: Add member access to a number of evsel variables
  perf python: Add optional cpus and threads arguments to parse_events
  perf python: Update ungrouped evsel leader in clone
  perf python: Avoid duplicated code in get_tracepoint_field
  perf python: Add evlist all_cpus accessor
  perf python: Add evlist.config to set up record options
  perf python tracepoint: Switch to using parse_events
