perf/core improvements and fixes:
- 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
cause of long term memory usage buildup, i.e. not processing PERF_RECORD_EXIT
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:
- Honor operator priority in libtraceevent (Namhyung Kim)
- Merge all perf_event_attr print functions (Peter Zijlstra)
- Check kmaps access to make code more robust (Wang Nan)
- Fix inverted logic in perf_mmap__empty() (He Kuang)
- Fix ARM 32 'perf probe' building error (Wang Nan)
- Fix perf_event_attr tests (Jiri Olsa)
