As 8cefeb8bd336 ("perf pmu-events: Introduce pmu_metrics_table") is
only on tmp.perf/core then it may be best to just squash this fix into
that.

Yeah, that was my intention, I'll fold it there to keep bisection,
thanks for fixing it so fast, I'll double check on my rk3399 board and
on again on the cross-build container.

tools/perf/pmu-events/pmu-events.c was a leftover from a previous build,
strange as I build using O=, not to clutter the source dir, so perhaps
handling that is missing, I'll check.

Fixed aarch64 specific one with:

diff --git a/tools/perf/arch/arm64/util/pmu.c b/tools/perf/arch/arm64/util/pmu.c
index 801bf52e2ea6..b4eaf00ec5a8 100644

 	if (pmu)
-		return perf_pmu__find_table(pmu);
+		return perf_pmu__find_events_table(pmu);
 
 	return NULL;
 }

Continuing...

tools/perf/pmu-events/pmu-events.c was a leftover from a previous build,
strange as I build using O=, not to clutter the source dir, so perhaps
handling that is missing, I'll check.

Fixed aarch64 specific one with:

diff --git a/tools/perf/arch/arm64/util/pmu.c b/tools/perf/arch/arm64/util/pmu.c

Thanks! Sorry for missing this one. Ideally we'd have less code under
arch/ . The previous error messages made me think you may need to
build clean.
