    perf tools: Add missing initialization of perf_sample.cpumode in synthesized samples · 3ea223ad
    Arnaldo Carvalho de Melo authored
    In 473398a2 ("perf tools: Add cpumode to struct perf_sample"), I
    missed some places where perf_sample fields are directly initialized in
    addition to what is done in perf_evsel__parse_sample(), namely when
    synthesizing PERF_RECORD_{MMAP*,COMM,FORK,EXIT} for pre-existing threads
    and also in intel_pt and intel_bts when synthesizing events from
    processor trace, the jitdump code also was affected, fix it.
    
    The problem was noticed with running:
    
      # perf record -e intel_pt//u true
      # perf script
    
    Where the samples wouldn't get resolved because perf_sample.cpumode
    would be left as zero, i.e. PERF_RECORD_MISC_CPUMODE_UNKNOWN, not
    resolving as kernel, hypervisor or user cpu modes.
