Weisbecker.
2. Report ignored local enqueue in nohz mode, courtesy of Frederic
Weisbecker.
3. Comment the reason behind BH disablement on batch processing,
courtesy of Frederic Weisbecker.
4. Forbid NOCB toggling on offline CPUs, courtesy of Frederic
Weisbecker.
5. Avoid confusing double write of rdp->nocb_cb_sleep, courtesy of
Frederic Weisbecker.
6. Only (re-)initialize segcblist when needed on CPU up, courtesy
of Frederic Weisbecker.
7. Rename nocb_gp_update_state to nocb_gp_update_state_deoffloading,
courtesy of Frederic Weisbecker.
8. Make nocb_nobypass_lim_per_jiffy static, courtesy of Jiapeng
Chong.
9. Fix missed nocb_timer requeue, courtesy of Frederic Weisbecker.
10. Disable bypass when CPU isn't completely offloaded, courtesy of
Frederic Weisbecker.
11. Remove stale comment above rcu_segcblist_offload(), courtesy of
