Default Natty SRU: Fix kswapd 100% CPU utilization

This is a multi-part message in MIME format.The following series was submitted to stable for 2.6.38.8 by Mel Gorman,
but NACK'd by Greg K-H as that stable kernel series is no longer
maintained (but accepted it for 2.6.39). I'd like to suggest that we
need this patch series for low resource Sandybridge based platforms.
