KVM: PPC: BOOK3S: Remove open coded make_dsisr in alignment handler
Use make_dsisr instead of open coding it. This also have the added benefit of handling alignment interrupt on additional instructions. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
