As discussed in:
https://lore.kernel.org/lkml/20240217005738.3744121-1-atishp@rivosinc.com/
preferring sysfs/json events consistently (with or without a given
PMU) will enable RISC-V's hope to customize legacy events in the perf
tool.

Some minor clean-up is performed on the way.

v2. Additional cleanup particularly adding better error messages. Fix
    some line length issues on the earlier patches.

Ian Rogers (16):
  perf parse-events: Factor out '<event_or_pmu>/.../' parsing
  perf parse-events: Directly pass PMU to parse_events_add_pmu
  perf parse-events: Avoid copying an empty list
  perf pmu: Refactor perf_pmu__match
  perf tests parse-events: Use branches rather than cache-references
  perf parse-events: Legacy cache names on all PMUs and lower priority
  perf parse-events: Handle PE_TERM_HW in name_or_raw
  perf parse-events: Constify parse_events_add_numeric
  perf parse-events: Prefer sysfs/json hardware events over legacy
  perf parse-events: Inline parse_events_update_lists
  perf parse-events: Improve error message for bad numbers
  perf parse-events: Inline parse_events_evlist_error
  perf parse-events: Improvements to modifier parsing
  perf parse-event: Constify event_symbol arrays
  perf parse-events: Minor grouping tidy up
  perf parse-events: Tidy the setting of the default event name
