Dapeng Mi f1f96511b1 perf: Fix 0 count issue of cpu-clock ... Currently cpu-clock event always returns 0 count, e.g., perf stat -e cpu-clock -- sleep 1 Performance counter stats for 'sleep 1': 0 cpu-clock # 0.000 CPUs utilized 1.002308394 seconds time elapsed The root cause is the commit 'bc4394e5e7 ("perf: Fix the throttle error of some clock events")' adds PERF_EF_UPDATE flag check before calling cpu_clock_event_update() to update the count, however the PERF_EF_UPDATE flag is never set when the cpu-clock event is stopped in counting mode (pmu->dev() -> cpu_clock_event_del() -> cpu_clock_event_stop()). This leads to the cpu-clock event count is never updated. To fix this issue, force to set PERF_EF_UPDATE flag for cpu-clock event just like what task-clock does.
