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

Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

mm/vmscan.c: In function 'snapshot_refaults':
mm/vmscan.c:2969:14: error: implicit declaration of function 'lruvec_page_state_local'; did you mean 'lruvec_page_state'? [-Werror=implicit-function-declaration]
   refaults = lruvec_page_state_local(lruvec, WORKINGSET_ACTIVATE);
              ^~~~~~~~~~~~~~~~~~~~~~~
              lruvec_page_state

Caused by commit

  3c1fea8fbdf7 ("mm: fix inactive list balancing between NUMA nodes and cgroups")

I applied the following patch for today:
