From: Borislav Petkov <bp@suse.de> Hi all, so this is something which should help fixing the MSR access to IC_CFG on AMD. The usefulness should come, however, from the unification and the additional family, model, stepping helpers in kvm in case one wants to know those of the guest CPU. Who knows, might be much more useful in the future. Quick testing shows it works, I'll hammer on it more after rc1 is out. Thanks.
