That would prevent people wanting to run real virtualised 8086 stuff that does use the AC trap, and other vm86 extensions to the basic real mode stuff. If you want an accurate real mode emulation you are stuck with Bochs, not down to the kernel but down to the fact vm86 is a mode for running 8086 applications under a 32bit system, not a mode for emulation of real mode. - 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/
