From 90d34b0e45df3bfe522e9e9d604c4c1a0253699d Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Tue, 29 Mar 2011 16:49:10 -0500 Subject: 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.
