The patch looks reasonable to me, but as DaveM mentioned in a later
mail, the do_wp_page case is supposed to be protected with a
semaphore.
Alas, I thought about this some more. And one piece of code needs to
be fixed for this invariant about the semaphore being held in the
fault processing code paths to be true everywhere... ptrace()...
