hi,
which commit/branch did you base on? I can't apply arm bits:

Applying: arm64: pmu: Add hook to handle pmu-related undefined instructions
Applying: arm64: perf: Enable pmu counter direct access for perf event on armv8
error: patch failed: arch/arm64/kernel/perf_event.c:836
error: arch/arm64/kernel/perf_event.c: patch does not apply
Patch failed at 0002 arm64: perf: Enable pmu counter direct access for perf event on armv8

thanks,
jirka
