parentperf trace: Handle perf.data files with no tracepoints (diff)
perf evlist: Fix id pos in perf_evlist__open()
Ensure the id_pos is correct when perf_evlist__open() is used. This fixes a problem introduced in 7556257 that broke 'perf kvm stat live' in that this tool wasn't updated to use the sample_type bits setting helpers.
