it adds HW and AML parts for CPU_Device._OST method handling to allow OSPM reports status of hot-(un)plug operation. And extends QMP command query-acpi-ospm-status to report CPU's OST info along with already reported PC-DIMM devices. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.
