    x86/Intel: IceLake D + Sapphire Rapids Xeons also support PPIN
    
    This is as per Linux commits a331f5fdd36d ("x86/mce: Add Xeon Sapphire
    Rapids to list of CPUs that support PPIN") and [tip.git] e464121f2d40
    ("x86/cpu: Add Xeon Icelake-D to list of CPUs that support PPIN"), just
    in case a subsequent change making use of the respective new CPUID bit
    doesn't cover either of these models.
