powerpc/pseries: Add POWER8NVL support to ibm,client-architecture-support call
If we do not provide the PVR for POWER8NVL, a guest on this system currently ends up in PowerISA 2.06 compatibility mode on KVM, since QEMU does not provide a generic PowerISA 2.07 mode yet. So some new instructions from POWER8 (like "mtvsrd") get disabled for the guest, resulting in crashes when using code compiled explicitly for POWER8 (e.g. with the "-mcpu=power8" option of GCC). Fixes: ddee09c099c3 ("powerpc: Add PVR for POWER8NVL processor") Cc: stable@vger.kernel.org # v4.0+ Signed-off-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
