David Alan Gilbert" Cc: Paolo Bonzini , "Michael S . Tsirkin" , Corey Minyard , Peter Maydell , Corey Minyard , Eduardo Habkost , Marcel Apfelbaum From: Corey Minyard Migration capability is being added for pm_smbus and SMBus devices. This change will allow backwards compatibility to be kept when migrating back to an old qemu version. Add a bool to the machine class tho keep smbus migration from happening. Future changes will use this.
