So we have three types of fields in these registers: a) features defined but not something we care about in Linux b) reserved fields c) features important to Linux I guess for (a), Linux may not even care if they don't match (though we need to be careful which fields we ignore). As for (b), even if they differ, since we don't know the meaning at this point, I think we should just ignore them. If, for example, they add a feature that Linux doesn't care about, they practically fall under the (a) category. Regarding exposing reserved CPUID fields to user, I assume we would always return 0.
Mark, Do you have any comments on this ? The list I have here is what you came up with in SANITY checks.
