[patch 26/32] mm/swap: fix for "mm: workingset: age nonresident information alongside anonymous pages"

[Andrew Morton <akpm@linux-foundation.org>]

From: Joonsoo Kim <iamjoonsoo.kim@lge.com>
Subject: mm/swap: fix for "mm: workingset: age nonresident information alongside anonymous pages"

Non-file-lru page could also be activated in mark_page_accessed()
and we need to count this activation for nonresident_age.

Note that it's better for this patch to be squashed into the patch
"mm: workingset: age nonresident information alongside anonymous pages".
