#     powerpc: Add POWER10 architected mode
#     
#     PVR value of 0x0F000006 means we are arch v3.1 compliant (i.e. POWER10).
#     This is used by phyp and kvm when booting as a pseries guest to detect
#     the presence of new P10 features and to enable the appropriate hwcap and
#     facility bits.
