Oops. How strange.
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)?
