[PATCH 00/14] NUMA balancing segmentation faults candidate fix on large machines

[Mel Gorman]

Alex Thorlton reported segementation faults when NUMA balancing is enabled
on large machines. There is no obvious explanation from the console what the
problem is so this series is based on code review.

The series is against 3.12. In the event it addresses the problem the
patches will need to be forward-ported and retested. The series is not
against the latest mainline as changes to PTE scan rates may mask the bug.
