Sorry, I should have put some background in the description. We have discussed if we can remove walk_iomem_res() in the thread below. https://lkml.org/lkml/2015/12/23/248 But this may depend on how we deal with the last remaining caller, walk_iomem_res() with "GART", being discussed in the thread below. I will update according to the outcome. https://lkml.org/lkml/2015/12/26/144 Thanks, -Toshi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
