Hillf Danton e03ed1190d netdevsim: init u64 stats for 32bit hardware ... commit 863a42b289 upstream. Init the u64 stats in order to avoid the lockdep prints on the 32bit hardware like INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.
