[Qemu-devel] [PATCH 1/4] s390x/cpu: Cleanup init in preparation for hotplug |
Date: |
Mon, 9 Nov 2015 10:17:37 -0500 |
Ensure a valid cpu_model is set upfront by setting the
default value directly into the MachineState when none is
specified. This is needed to ensure hotplugged CPUs share
the same cpu_model.
