It requires that all CPUs are online. However there is an early_initcall() wrapper for the PMU init funciton init_hw_perf_events(), so that pmu init funciton is called in do_pre_smp_initcalls() which before function smp_init(). Function reset_counters() cannot work on other CPUs since they haven't boot up still. Here replace the wrapper early_initcall() with pure_initcall(), so that the PMU init function is called after every cpu is online.
