Caused by

Presumably requires a backport of

Mark or Laura, can you confirm that this is the correct fix? I see additional uses of lm_alias in mainline, but only this one backported to stable, not sure if only this one is required there, or we want the others as well.

I don't think backporting lm_alias is the correct fix. That was introduced as part of DEBUG_VIRTUAL for arm64 which isn't present at all for 4.9. If DEBUG_VIRTUAL isn't present, there should be no need for this fix since it's handled by existing code. I think the patch should be dropped assuming there isn't another issue with kasan.
Thanks, Laura

I've just dropped it now, sorry for this.
