Hi Tim. We agreed to get the common stuff and one architecture done before proceeding with the rest. Please stick to that plan so we avoid patch-bombing lkml + maintainers. When we have this ready it will be a simple one-patch-per-arch to cover the rest. I will comment on your common patches for now. Sam
