Geert,
the crash was introduced after Finn re-livened the dead code (and
thereby bypassed exception table fix-up AFAICS).
Cheers,
Michael

I think I can find a solution for that. The main reason for this RFC is a
bunch of question I can't answer:
- What are the implications of the existing logic error?
- What was the author trying to achieve? Why a special case for RMW
faults?
- How much latitude is there to change this without breaking weird
platforms?
That's my biggest worry for now.
- Should the dead code be deleted because the live algorithm cannot be
improved upon? (The present algorithm works fine for PDMA for example.)
If it introduced a crash, it is not dead code?
