What am I missing here? > There is no such thing as "flat mode" in 64-bit mode. We use a #PF handler to emulate it, but we add the normal kernel offset when doing so. In the 32-bit case the problem is that the kernel offset is not available while in linear mode. It *could* be created using segment bases, but that would break Xen, I'm pretty sure, and possibly some other too-clever environments. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
