Note that if ZONE_DMA is off then ZONES_WIDTH may become
0 and therefore also ZONES_PGSHIFT is zero.

If you then do

#define ZONEID_PGSHIFT ZONES_PGSHIFT

then ZONEID_PGSHIFT will be 0!

So this could be an issue for the optional ZONE_DMA patch.

Could you also make sure that ZONEID_PGSHIFT is set correctly even if 
ZONES_WIDTH is zero?

This affects the optional ZONE_DMA patch. zone table removal should be 
fine with just the above patch.
