Well, I'm happy for the whole series to go in via Greg's tree or however the coresight patches go in (that's why I acked them). The last three patches depend on the first four, so you might as well send them all together. I'd split the series only if there's a conflict with the arm64 tree (I haven't checked). -- Catalin _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
