cpu: don't allow negative core id
With pseries machine type a negative core-id is not managed properly: -1 gives an inaccurate error message ("core -1 already populated"), -2 crashes QEMU (core dump) As it seems a negative value is invalid for any architecture, instead of checking this in spapr_core_pre_plug() I think it's better to check this in the generic part, core_prop_set_core_id() Signed-off-by:Laurent Vivier <lvivier@redhat.com> Message-Id: <20170802103259.25940-1-lvivier@redhat.com> Reviewed-by:
