-Subject: Prevent NULL pointer deref in grab_swap_token
-References: 159260
-
-grab_swap_token() assumes that the current process has an mm struct,
-which is not true for kernel threads invoking get_user_pages().  Since
-this should be extremely rare, just return from grab_swap_token()
-without doing anything.
