Subject: [PATCH] mm: rmap: fix build warning

From: Bob Liu <[email-masked]>
Date: Thu, 25 Oct 2012 16:50:50 +0800

mm/rmap.c: In function 'try_to_unmap_cluster':
mm/rmap.c:1361:9: warning: unused variable 'pud' [-Wunused-variable]
mm/rmap.c:1360:9: warning: unused variable 'pgd' [-Wunused-variable]

I forgot to del these variable in my commit:
0981230ec3206f98dcc58febfef9fd35b540d25a mm: introduce mm_find_pmd()
