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 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
