While we do have a bunch of debugging we can turn on in cputlb there
is an argument for making tlb_fill a generally available trace point.
Any fault (via probe or access) will have to be preceded by a tlb_fill
for the address in question.
We don't bother logging the return address as that will be a host
address associated with translation and therefor can move around with
ASLR.
In my particular case I'm trying to track down a difference in memory
fault exception patterns between record and replay phases.
