To add support for running libvirt on PowerPC, a CPU driver for the PowerPC platform must be added. Most generic cpu driver routines such as CPU compare, decode, etc are based on CPUID comparison and are not relevant for non-x86 platforms. Here, we introduce stubs for relevant PowerPC routines invoked by libvirt. Signed-off-by: Prerna Saxena <prerna@linux.vnet.ibm.com> Signed-off-by: Anton Blanchard <anton@au.ibm.com>
