[PATCH 3.14 59/77] mm: do not use atomic operations when releasing pages

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Mel Gorman <mgorman@xxxxxxx>

commit e3741b506c5088fa8c911bb5884c430f770fb49d upstream.

There should be no references to it any more and a parallel mark should
not be reordered against us.  Use non-locked varient to clear page active.
