mm/ is not W=1 clean for make allnoconfig but this patch accidentally
made it worse for i386 with the warning
mm/vmstat.c: In function ‘refresh_cpu_vm_stats’:
mm/vmstat.c:785:34: warning: unused variable ‘pcp’ [-Wunused-variable]
struct per_cpu_pages __percpu *pcp = zone->per_cpu_pageset;
^~~
This is a second fix to the mmotm patch
mm-page_alloc-split-per-cpu-page-lists-and-zone-stats.patch.
