[Qemu-devel] [PATCHv5 2/4] pseries: Move CPU compatibility property to machine

2017-06-01 Thread David Gibson
Server class POWER CPUs have a "compat" property, which is used to set the backwards compatibility mode for the processor. However, this only makes sense for machine types which don't give the guest access to hypervisor privilege - otherwise the compatibility level is under the guest's control.
