While using ticket lock, cores repeatedly poll the lock variable. This is replaced by rte_wait_until_equal API. Running ticketlock_autotest on ThunderX2, Ampere eMAG80, and Arm N1SDP[1], there were variances between runs, but no notable performance gain or degradation were seen with and without this patch.
