From 078937549f47a933aa8039acfa36b325e8090ecb Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Mon, 8 Jul 2019 20:38:15 +0100 Subject: [PATCH] ARM: 8875/1: Kconfig: default to AEABI w/ Clang [ Upstream commit a05b9608456e0d4464c6f7ca8572324ace57a3f4 ] Clang produces references to __aeabi_uidivmod and __aeabi_idivmod for arm-linux-gnueabi and arm-linux-gnueabihf targets incorrectly when AEABI is not selected (such as when OABI_COMPAT is selected). While this means that OABI userspaces wont be able to upgraded to kernels built with Clang, it means that boards that don't enable AEABI like s3c2410_defconfig will stop failing to link in KernelCI when built with Clang.
