This patch eliminates the false hole which can form between ZONE_NORMAL and
ZONE_HIGHMEM.  This is most easily seen when 4g/4g split is enabled, but
it's always broken, and we just happen not to hit it most of the time.
Basically, the patch changes the allocation of the numa remaps regions (the
source of the holes) such that they officially fall within VMALLOC space,
where they belong.

Tested in -mjb for a couple of months, and again against 2.6.7-mm1.
