The original required CPUID bit set for x86-64 came out of very detailed discussions and thinking from AMD. I think they had good reasons to chose the current set. I would only recommend to depart from it for very good reasons and frankly you haven't given any. You're talking about removing two instructions. One problem that we had in the past is that some simulators only implement the absolutely minimum feature set and you might have well broken one of these with this. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
