I'm not sure if we do. I'd rather keep everything together, spreading
the implementation around the kernel is inconvenient. We already have
software tag-based KASAN implementation (which is also arm64-specific)
in the common code. We could, perhaps, rename mte.c into something
more generic, with other potential future hardware modes in mind.
