Strictly we shouldn't care - we _know_ we've already hit a kernel bug and
who knows, perhaps that buggy code did an unbalanced preempt_disable(). So
make the oops code more robust.
otoh, we don't want to be hiding a bug. What piece of code guarantees that
we ender the oops code with preemption disabled?
