Subject: [PATCH 14/27] KVM: PPC: Magic Page BookE support
=20
As we now have Book3s support for the magic page, we also=20
need BookE to
join in on the party.
=20
This patch implements generic magic page logic for BookE and specific
TLB logic for e500. I didn't have any 440 around, so I didn't dare to
blindly try and write up broken code.
