Hi all, After merging the rcu tree, today's linux-next build (arm multi_v7_defconfig) failed like this: arch/arm/mach-imx/cpuidle-imx6q.c: In function 'imx6q_enter_wait': arch/arm/mach-imx/cpuidle-imx6q.c:32:7: error: implicit declaration of function 'need_resched'; did you mean 'tif_need_resched'? [-Werror=implicit-function-declaration] 32 | if (!need_resched()) | ^~~~~~~~~~~~ | tif_need_resched Caused by commit 7ca83ec735ce ("ARM: imx6q: Fix missing need_resched() check after rcu_idle_enter()") I have used the rcu tree from next-20201223 for today. -- Cheers, Stephen Rothwell
