I already indicated that the *pre-existing* set of helpers are enough
for what we want to do, that we *already* use them for KVM/arm64, and
that I didn't need nor want two ways to do the same thing in the same
code base.

My opinion hasn't changed on that front, and I don't see a point in
these patches.
