And then if somebody actually needs to pass in "modified fault state"
(ie that whole "I'm doing fault-around, so I'll use multiple
addresses") they'd never modify the address in the fault info, they'd
just pass the address as an explicit argument (like most cases already
do - the "change addr or flags in vmf" is actually already _fairly_
rare).

Alright then, I'll take another crack at this for v3 and see how far I
get.

But please do keep it as a separate patch, and if it turns out to be
ugly for whatever reason, treat it as just a "maybe that would help"
suggestion rather than anything stronger..
