Alex Richardson fa2528ac64 Use atomic loads/stores when updating td->td_state ... KCSAN complains about racy accesses in the locking code. Those races are fine since they are inside a TD_SET_RUNNING() loop that expects the value to be changed by another CPU. Use relaxed atomic stores/loads to indicate that this variable can be written/read by multiple CPUs at the same time. This will also prevent the compiler from doing unexpected re-ordering. Reported by: GENERIC-KCSAN Test Plan: KCSAN no longer complains, kernel still runs fine.
