It's nice to see eagle-eyed review of the tag summary. In this case, I forgot to drop a couple of sections from the previous tag I wrote -- we use the same tag name each time ("arm64-upstream"), so it gets pre-filled with the old contents when we update it and, since Catalin and I take it in turns, that's why 6.16 showed up here. The good news is that the actual pull request is fine and Linus has already pulled it. I now wonder how many quality news sites will report that arm64 is re-enabling SME in 6.18 ;) Will
