This patch adds a hack to fix the conversion similarly like MIPS. Note that this doesn't fix perfectly: the pages should be marked with proper pgprot value. This will be done in a future implementation like the conversion to dma_mmap_coherent(). Acked-by: Benjamin Herrenschmidt Signed-off-by: Takashi Iwai --- Reading git-diff-tree failed
