That was my initial reaction but when I reread the documentation the Intel folks are actually saying even back in Pentium MMX days that it isnt guaranteed that the FP/MMX state are not seperate registers - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
