Hello!
This series provides some fixes to prevent sending IPIs to offline
CPUs and also replaces most uses of cond_resched_rcu_qs() with the new
and improved cond_resched(). There are still a few remaining uses of
cond_resched_rcu_qs() in rcutorture because the mechanisms that strengthen
cond_resched() rely on RCU making forward progress. This series contains:
1. Stop resched_cpu() from sending IPIs to offline CPUs.
2. Stop switched_to_rt() from sending IPIs to offline CPUs.
3. Move netfilter from cond_resched_rcu_qs() to cond_resched().
4. Move mm from cond_resched_rcu_qs() to cond_resched().
5. Move workqueue from cond_resched_rcu_qs() to cond_resched().
6. Move trace from cond_resched_rcu_qs() to cond_resched().
7. Move softirq from cond_resched_rcu_qs() to cond_resched().
8. Move fs from cond_resched_rcu_qs() to cond_resched().
9. Remove cond_resched_rcu_qs() from documentation.
10. Improve performance by accounting for rcu_all_qs() in cond_resched().
Thanx, Paul
