Subject: [092/111] HWPOISON: remove the anonymous entry

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Wu Fengguang <fengguang.wu@...el.com>

commit 9b9a29ecd75e310f75a9243e1c3538ad34598fcb upstream.

(PG_swapbacked && !PG_lru) pages should not happen.
Better to treat them as unknown pages.
