Sorry for not being clear enough, I meant three implementations of page_to_dma(), depending on highmem and platform: return (dma_addr_t)__virt_to_bus((unsigned long)page_address(page)); return (dma_addr_t)__pfn_to_bus(page_to_pfn(page)); return __arch_page_to_dma(dev, page); The generic code right now does the first, which won't work with highmem and also won't handle platform specific requirements that are not present on the other architectures.
