    The fact that the mouse stops working is indicative that this patch doesn't
    actually fix the problem, it's just pushing it around in the kernel - sooner
    or later something *else* is going to go pear-shaped on the null *mm. The right
    fix is to figure out why mm is bogus and fix that issue.
