From: Laurent Dufour <lduf...@linux.vnet.ibm.com>
During KVMPPC_H_CAS processing, the cpu-version updated value is stored
without taking care of the current endianess. As a consequence, the guest
may not switch to the right CPU model, leading to unexpected results.
If needed, the value is now converted.
