This looks.. dubious. You're making a change to generic code for a
powerpc feature. Plus it's not entirely clear that simply increasing
the variable size is a good fix here. Again, I think since this is a
256k page special case it will simplify things to get the <=64k stuff
first, then handle this in another patch.
