OMAP requires bo-pages to be in the DMA32 zone. Explicitly request this by setting __GFP_DMA32 as mapping-gfp-mask during shmem initialization. This drops HIGHMEM from the gfp-mask and uses DMA32 instead. shmem-core takes care to relocate pages during swap-in in case they have been loaded into the wrong zone. It is _not_ possible to pass __GFP_DMA32 to shmem_read_mapping_page_gfp() as the page might have already been swapped-in at that time. The zone-mask must be set during initialization and be kept constant for now. Remove the now superfluous TODO in omap_gem.c.
