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@arm.com 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). -- Catalin
