Wrong - there is a difference. For pre-ARMv6 CPUs, it returns memory with different attributes from DMA coherent memory. And we're not going to sweep away pre-ARMv6 CPUs any time soon. So you can't ignore dma_alloc_writecombine() which must remain to sanely support framebuffers. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
