Subject: [PATCH] PPC: KVM: Disable mmu notifier check

When using hugetlbfs (which is required for HV mode KVM on 970), we
check for MMU notifiers that on 970 can not be implemented properly.

So disable the check for mmu notifiers on PowerPC guests, making
KVM guests work there, even if possibly racy in some odd circumstances.
