Re: [Powertop] [PATCH POWERTOP V3] resolve the bug that powertop doesn't show correct frequency stats

Hi Sergey I tested in powertop tool and find that there is no cpu_id filed in some perf events. such as sched_switch, hrtimer_expire_exit and so on. so we can't modify this change in src/perf/perf_bundle (perf_sample's perf_event_header). And we didn't find any bugs on other perf events. So we only modified it in src/cpu/cpu.cpp.
