target-ppc: Use QOM method dispatch for MMU fault handling
After previous cleanups, the many scattered checks of env->mmu_model in the ppc MMU implementation have, at least for "classic" hash MMUs been reduced (almost) to a single switch at the top of cpu_ppc_handle_mmu_fault(). An explicit switch is still a pretty ugly way of handling this though. Now that Andreas Färber's CPU QOM cleanups for ppc have gone in, it's quite straightforward to instead make the handle_mmu_fault function a QOM method on the CPU object. This patch implements such a scheme, initializing the method pointer at the same time as the mmu_model variable. We need to keep the latter around for now, because of the MMU types (BookE, 4xx, et al) which haven't been converted to the new scheme yet, and also for a few other uses. It would be good to clean those up eventually. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
