I've already tagged a tags/asm-generic-6.15-2 with your fix included
and the same tag description.

I don't think it's worth doing a partial pull here.

Linus, if you have already pulled the tags/asm-generic-6.15 tag,
I suggest you just apply the fix directly yourself, otherwise
you can use the tags/asm-generic-6.15-2 tag instead, or hold off
for today and wait for me to send a new pull request after
I get an ok from Nathan.
