From: Herton R. Krzesinski <herton(a)redhat.com&gt; Revert "ARM: fix __get_user_check() in case uaccess_* calls are not inlined" This reverts commit 80660062260dec4bdca9540922577542c16145e8. This was v1 of the patch posted upstream: https://lore.kernel.org/patchwork/patch/1132459/ A second version was sent after it: https://patchwork.kernel.org/project/linux-arm-kernel/patch/2019100108370... And it is the v2 the one which really was integrated upstream through this commit: ... commit 851140ab0d083c78e5723a8b1cbd258f567a7aff Author: Masahiro Yamada <yamada.masahiro(a)socionext.com&gt; Date: Wed Oct 2 11:28:02 2019 +0100 ARM: 8908/1: add __always_inline to functions called from __get_user_check() ... Thus revert the old version which was applied to ARK and shouldn't be needed anymore since the other version is already upstream. Signed-off-by: Herton R.
