This made the value put_user was putting to user space wrong. But the code continued to build cleanly without errors. Introducing a temporary fixes this problem and at least with gcc-3.3.5 does not cause gcc any problems with optimizing out the temporary. gcc-4.x using SSA internally ought to be even better at optimizing out temporaries, so I don't expect a temporary to become a problem. Especially because in all correct cases the types on both sides of the assignment to the temporary are the same. Signed-off-by: Eric W.
