I have no idea what MorphOS uses, but I bet HPT as well. That is
because HPT is fastest in general. Software TLB reloads are good in
special cases only; the most common is real-time OSes, which can use its
lower guaranteed latency for some special address spaces (and can have a
simpler address map in general).
