Thanks Linus, David for the quick fix and upstreaming. I tested it as
well on arm64 and works fine both with MTE enabled and disabled. I had a
somewhat similar proposal here:

https://lore.kernel.org/r/aRIEkLw7BofLjOWs@xxxxxxx

though dealing with all pages in tag_clear_highpages() is better, it
gives us some room for (small) optimisation later on (e.g. only flag the
head of a compound page like we do for hugetlb).
