Subject: linux-next: build failure after merge of the rcu tree

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.
