    perf pmu: Remove perf_pmu__hybrid_mounted · 4ced2c24
    Ian Rogers authored
    perf_pmu__hybrid_mounted is used to detect whether cpu_core or
    cpu_atom is mounted with a non-empty cpus file by
    pmu_lookup. Discussion [1] showed the empty cpus file check to be
    redundant and so pmu_lookup needn't have a call to
    perf_pmu__hybrid_mounted.
    
    Checking hybrid_mounted in pmu_is_uncore is redundant as the next
    cpumask read will fail returning false.
    
    Reduce the scope of perf_pmu__find_hybrid_pmu by making it static.
