KVM: PPC: e500: emulate SVR
Return the actual host SVR for now, as we already do for PVR. Eventually we may support Qemu overriding PVR/SVR if the situation is appropriate, once we implement KVM_SET_SREGS on e500. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Alexander Graf <agraf@suse.de>
