Martin J. Bligh e310fd4325 [PATCH] Fix NUMA node sizing in nr_free_zone_pages
We are iterating over all nodes in nr_free_zone_pages().  Because the
fallback zonelists contain all nodes in the system, and we walk all the
zonelists, we're counting memory multiple times (once for each node).  This
caused us to make a size estimate of 32GB for an 8GB AMD64 box, which makes
all the dirty ratio calculations, etc incorrect.

There's still a further bug to fix from e820 holes causing overestimation
as well, but this fix is separate, and good as is, and fixes one class of
problems.  Problem found by Badari, and tested by Ram Pai - thanks!
