[PATCH tip/core/rcu 0/10] Dyntick changes for v4.20/v5.0

Hello! Now that there is only one rcu_data structure per CPU, there isn't a whole lot of point in maintaining a separate per-CPU rcu_dynticks structure. This series therefore merges the rcu_dynticks structure into the rcu_data structure. 1. Remove unused rcu_dynticks_snap() from Tiny RCU.
