And... is get_user right primitive for accessing area that may not be there?
I'm pretty sure there's precedent for using __get_user in this way (get_user is a different matter, since it cares about whether the address is within the user part of the address space). Certainly in arch/i386 code there shouldn't be a problem. Is there some other way to achieve the same effect (without manually setting up an exception/fixup block)? J
