The data type profiling per-sample stream keys cross-CPU contention on sample->cpu, which without PERF_SAMPLE_CPU is the "no CPU info" sentinel, making same-instance accesses from different cores indistinguishable from same-CPU traffic. 'perf mem record' already passes -d and -W to the record parser, add --sample-cpu and document it in perf-mem(1). Also grow rec_argv: the new entry overflows it on PMUs with separate load and store events, as the space for the fixed arguments was not reserved.
