The other thing is that "legacy" in this context is fungible. No IOMMU was legacy until the Intel x86-64 chips came out, and I can promise you that some legacy code will be necessary once we start seeing VIA and others come out with embedded x86-64. On the other hand, it's pretty bloody safe to assume that we'll never see an x86-64 chip without CPUID, CMOV, FXSAVE, SSE-2, CMPXCHG, etc. -hpa - 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/
