This hook will replace the (user-only mode specific) handle_mmu_fault hook, and the (system mode specific) tlb_fill function. The handle_mmu_fault hook was written as if there was a valid way to recover from an mmu fault, and had 3 possible return states. In reality, the only valid action is to raise an exception, return to the main loop, and deliver the SIGSEGV to the guest. Note that all of the current implementations of handle_mmu_fault for guests which support linux-user do in fact only ever return 1, which is the signal to return to the main loop. Using the hook for system mode requires that all targets be converted, so for now the hook is (optionally) used only from user-only mode.
