This version of Sahara's arch_within_stack_frames() series replaces the
open-coded stack walker with a call to arm64's existing walker.

Is this still in progress? Seemed like it was very close?

Ah, sorry, I lost track of this when it jumped between mail folders... Sahara
had comments on the last patch.

How does all this fit with Al Viro's uaccess unification tree?:
