Commit b1c5356e873c ("KVM: PPC: Convert to the gfn-based MMU notifier
callbacks") causes unmap_gfn_range and age_gfn callbacks to only work
on the first gfn in the range. It also makes the aging callbacks call
into both radix and hash aging functions for radix guests. Fix this.

Add warnings for the single-gfn calls that have been converted to range
callbacks, in case they ever receieve ranges greater than 1.

Sorry for the breakage.  I queued this patch.

Thanks. Are you planning to send it to Linus before rc1?

If not I can pick it up as I already have some things in my next and am
intending to send a pull request anyway.

cheers
