Could you reword above sentence? We are already starting off with
untagged_addr() not being no-op for arm64 and sparc64. It will expand
further potentially. So something more along the lines of "Define it as
noop for architectures that do not support memory tagging". The first
paragraph in the log can also be rewritten to be not specific to arm64.

Well, as of this patch this actually is a no-op for everyone.

Linus, what do you think of applying this patch (maybe with a slightly
fixed up commit log) to 5.2-rc so that we remove a cross dependency
between the series?

(I have adjusted the patch description and have just sent it out
separately from the series).
