KVM: PPC: E500: Implement MMU notifiers
The e500 target has lived without mmu notifiers ever since it got introduced, but fails for the user space check on them with hugetlbfs. So in order to get that one working, implement mmu notifiers in a reasonably dumb fashion and be happy. On embedded hardware, we almost never end up with mmu notifier calls, since most people don't overcommit. Signed-off-by: Alexander Graf <agraf@suse.de>
