perf/core improvements and fixes:

Browse source 
- Teach about perf_event_attr.clockid to 'perf record' (Peter Zijlstra)
 
 - perf sched replay improvements for high CPU core count machines (Yunlong Song)
 
 - Consider PERF_RECORD_ events with cpumode == 0 in 'perf top', removing one

   events (Arnaldo Carvalho de Melo)
 
 - Add 'I' event modifier for perf_event_attr.exclude_idle bit (Jiri Olsa)
 
 - Respect -i option 'in perf kmem' (Jiri Olsa)
 
 Infrastructure:
