SLAB_CACHE_DMA32??? WTH is going on here? We are trying to get rid of
the dma slab array.

See the previous two patches in this series. If there's

For level 1/2 pages, ensure GFP_DMA32 is used if CONFIG_ZONE_DMA32
is defined (e.g. on arm64 platforms).
For level 2 pages, allocate a slab cache in SLAB_CACHE_DMA32.
Also, print an error when the physical address does not fit in
32-bit, to make debugging easier in the future.
