it adds CPU objects to DSDT with _STA method and QEMU side of CPU hotplug interface initialization with registers sufficient to handle _STA requests, including necessary hotplug callbacks in piix4,ich9 code. Hot-(un)plug hw/acpi parts will be added by corresponding follow up patches. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
