Thanks, although this was picked up by -tip a couple of days ago [1] since the READ_ONCE() rework relies on it to avoid breaking the sparc32 build. It's obviously harmless to go in both trees, but if you don't need it for anything then you may want to drop these to avoid duplicate commits in mainline.
