I'm in favour. I do not think this contributes an ABI change, as these values are explicitly outside of the ABI. What it does mean is that the buffer contents are consistent with our cache tracking; and for userspace the results were always undefined. So we should at least be able to guarantee that the data written by userspace from the CPU is visible. After that, your caches are on your own.
