I still think this is unnecessary churn. You then end up with
ioremap_prot() having no callers outside of arch/ and if core code just
defines ioremap_user_prot() to ioremap_prot() for everybody apart from
arm64 then the intent isn't clear at all.

FWIW, I've had a crack at implementing this here:

I can post the patches at -rc1.
