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

Hi all,

After merging the percpu tree, today's linux-next build (sparc defconfig)
failed like this:

mm/percpu.c: In function 'pcpu_balance_workfn':
mm/percpu.c:1613:3: error: implicit declaration of function 'cond_resched'; did you mean 'should_resched'? [-Werror=implicit-function-declaration]
   cond_resched();
   ^~~~~~~~~~~~
   should_resched

Caused by commit

  accd4f36a7d1 ("percpu: add a schedule point in pcpu_balance_workfn()")

I have added this patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Mon, 26 Feb 2018 14:47:39 +1100
Subject: [PATCH] percpu: include sched.h for cond_resched()
