When not doing Linux hacks I work on compilers and runtime systems, and I agree that a model with x86_64 native mode enabled (and thus the extra registers and addressing modes) but still in a 32-bit address space looks like a very interesting option for those applications that don't need tons of address space. /Mikael - 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/ | ||||||||||||
