Subject: [PATCH v2 00/13] Python motivated fixes and cleanup

Various fixes and clean ups done as part of creating the ilist app,
the v4 patch series of which is posted here:
https://lore.kernel.org/lkml/20250628000929.230406-1-irogers@google.com/

These patches are separated out to give something smaller to review
before adding features. As requested by Namhyung.

v2: Additional evlist copying fixes found by testing on hybrid. Add
    fix to set the error for out of bound cpu map and thread map item
    calls.

Ian Rogers (13):
  perf hwmon_pmu: Avoid shortening hwmon PMU name
  perf parse-events: Minor tidy up of event_type helper
  perf spark: Fix includes and add SPDX
  perf pmu: Tolerate failure to read the type for wellknown PMUs
  perf metricgroup: Factor out for-each function and move out printing
  perf stat: Move metric list from config to evlist
  perf expr: Accumulate rather than replace in the context counts
  perf jevents: If the long_desc and desc are identical then drop the
    long_desc
  perf python: In str(evsel) use the evsel__pmu_name helper
  perf python: Fix thread check in pyrf_evsel__read
  perf python: Correct pyrf_evsel__read for tool PMUs
  perf python: Improve leader copying from evlist
  perf python: Set index error for invalid thread/cpu map items
