    We have the following existing _SHORT variants:

    _G
    _EP
    _EX
    _CORE
    _ULT
    _GT3E
    _XEON_D
    _MOBILE
    _DESKTOP
    _NNPI
    _MID
    _TABLET
    _PLUS

    So we should document the list of valid and usable ones and either fixup
    broken ones or document that they are historic ballast and not to be used
    for new ones. Otherwise you end up with the same discussions again.

    Thanks,

    tglx
