__GFP_HIGHMEM flag is cleared by upper layer functions (in include/linux/dma-mapping.h) so we'll never get a __GFP_HIGHMEM flag in arch_dma_alloc gfp argument. That's why alloc_pages will never return highmem page here. Get rid of highmem pages handling and cleanup arch_dma_alloc and arch_dma_free functions.
