Hmm, unsure of what was removed. Prefetching across page boundaries should have always been broken/bad from the perspective of the prefetchers. Since they are in the memory system which is purely physical addresses in gem5. Without a TLB/walker interface to the prefetchers, there is no proper way for them to prefetch across page boundaries.
Perhaps you were just lucking out with good translations earlier?
