[Qemu-devel] [PATCH 4/4] spapr: Add sPAPRMachineClass


From: David Gibson
Subject: [Qemu-devel] [PATCH 4/4] spapr: Add sPAPRMachineClass
Date: Thu, 7 May 2015 13:57:04 +1000

Currently although we have an sPAPRMachineState descended from MachineState
we don't have an sPAPRMAchineClass descended from MachineClass.  So far it
hasn't been needed, but several upcoming features are going to want it,
so this patch creates a stub implementation.
