    Other architectures define this differently.

    arch/ia64/include/asm/dma-mapping.h:#define DMA_ERROR_CODE 0
    arch/microblaze/include/asm/dma-mapping.h:#define DMA_ERROR_CODE
    (~(dma_addr_t)0x0)
    arch/powerpc/include/asm/dma-mapping.h:#define DMA_ERROR_CODE
    (~(dma_addr_t)0x0)
    arch/sparc/include/asm/dma-mapping.h:#define DMA_ERROR_CODE
    (~(dma_addr_t)0x0)
    arch/x86/include/asm/dma-mapping.h:#define DMA_ERROR_CODE 0

    Any idea what the reason is?
