commit 6f64ec74 upstream. Similar to the fix provided by Dominik Heidler in commit 9b3dc0a1 ("l2tp: cast l2tp traffic counter to unsigned") we need to take care of 32bit kernels in dev_get_stats(). When using atomic_long_read(), we add a 'long' to u64 and might misinterpret high order bit, unless we cast to unsigned.
