Hi Andrew,

After merging the akpm tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

mm/rmap.c: In function 'try_to_unmap_cluster':
mm/rmap.c:1364:9: warning: unused variable 'pud' [-Wunused-variable]
mm/rmap.c:1363:9: warning: unused variable 'pgd' [-Wunused-variable]

Introduced by commit "mm: introduce mm_find_pmd()".
