    perf parse-events: Don't reorder ungrouped events by PMU · 327daf34
    Ian Rogers authored
    The pmu_group_name by default returns "cpu" which on non-hybrid/ARM
    means that ungrouped software, and hardware events are all going to
    sort by the original insertion index.
    
    However, on hybrid and ARM wildcard expansion may mean the PMU name is
    set and events will be unnecessarily reordered - triggering the
    reordering warning.
