Christoph Lameter 96df9333c9 [PATCH] mm: dequeue a huge page near to this node 
This was discussed at
http://marc.theaimsgroup.com/?l=linux-kernel&m=113166526217117&w=2

This patch changes the dequeueing to select a huge page near the node
executing instead of always beginning to check for free nodes from node 0.
This will result in a placement of the huge pages near the executing
processor improving performance.

The existing implementation can place the huge pages far away from the
executing processor causing significant degradation of performance.  The
search starting from zero also means that the lower zones quickly run out
of memory.  Selecting a huge page near the process distributed the huge
pages better.
