It recently became apparent that KVM/arm64 is the last bit of the kernel that still uses perf_num_counters(). As I went ahead to address this, it became obvious that all traces of oprofile had been eradicated from all architectures but arm64, s390 and sh (plus a bit of cruft in the core perf code). With KVM fixed, perf_num_counters() and perf_pmu_name() are finally gone. Thanks, M.
