[Qemu-ppc] [PULL 1/8] target-ppc: KVMPPC_H_CAS fix cpu-version endianess


From: Alexander Graf
Subject: [Qemu-ppc] [PULL 1/8] target-ppc: KVMPPC_H_CAS fix cpu-version endianess
Date: Tue, 8 Jul 2014 12:20:11 +0200

From: Laurent Dufour <address@hidden>

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.
