Subject: [PATCH rcu 04/12] rcuscale: Stop testing RCU Tasks Rude asynchronous APIs

From: "Paul E. McKenney" <paulmck@...nel.org>

The call_rcu_tasks_rude() and rcu_barrier_tasks_rude() APIs are currently
unused.  Furthermore, the idea is to get rid of RCU Tasks Rude entirely
once all architectures have their deep-idle and entry/exit code correctly
marked as inline or noinstr.  As a step towards this goal, this commit
therefore removes these two functions from rcuscale testing.
