However, if you feel strongly about it, I am happy to > move back those two functions to arm64. I don't have a strong view on this, only if there's a risk at some point of the implementations diverging (e.g. quirks). We can revisit it if that happens. It may be worth swapping patches 1 and 2 so that you don't have an arm64_* function in the core code after the first patch (more of a nitpick). Either way, feel free to add my ack on both patches: Acked-by: Catalin Marinas _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
