OS aside, aren't there CPU instructions to store and restore all registers for the purposes of context switching? This takes the requirement away from every OS to somehow know exactly how many registers there are in the CPU that it happens to be running on. i.e. an older or non-updated OS running on newer or slightly different hardware.
