Tsirkin" , Igor Mammedov We don't touch isapc when we change guest ABI and add new entries to PC_COMPAT_* or new PCMachineClass compat flags. This means isapc never guaranteed guest ABI and cross-QEMU-version live migration compatibility. There's no point in keeping code for kvm-pv-eoi and APIC ID compatibility in pc_init_isa().
