Debian 8 aka Jessie had gcc-4.8.4 and gcc-4.9.2. So do we care about people who haven't bothered to upgrade userspace since 2017? If so, we can't go past 4.9. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
