Has anyone face such issue before? My kernel version is 4.2 and ILP32 patches are under development being backported from http://lkml.iu.edu/hypermail/linux/kernel/1601.1/05453.html. Sources for 4.5 available at https://github.com/norov/linux Please let me know if any additional information is necessary. -Vadim _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
