There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's functions. This commit therefore removes the rsp parameter from rcu_nocb_cpu_needs_barrier(), rcu_spawn_one_nocb_kthread(), rcu_organize_nocb_kthreads(), rcu_nocb_cpu_needs_barrier(), and rcu_nohz_full_cpu().

There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's functions. This commit therefore removes the rsp parameter from rcu_boot_init_percpu_data(), rcu_init_percpu_data(), rcu_cleanup_dying_idle_cpu(), and rcu_migrate_callbacks(). While in the neighborhood, line the last three into rcutree_prepare_cpu(), rcu_report_dead() and rcutree_migrate_callbacks(), respectively. This also gets rid of the for_each_rcu_flavor() calls that were in those tree functions. Signed-off-by: -

There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's functions. This commit therefore removes the rsp parameter from __rcu_pending(), and also inlines it into rcu_pending(), removing the for_each_rcu_flavor() while in the neighborhood.. Signed-off-by: -

There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's functions. This commit therefore removes the rsp parameter from rcu_cleanup_dying_cpu() and rcu_cleanup_dead_cpu(). And, as long as we are in the neighborhood, inlines them into rcutree_dying_cpu() and rcutree_dead_cpu(), respectively. This also eliminates a pair of for_each_rcu_flavor() loops. Signed-off-by: -

There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's functions. This commit therefore removes the rsp parameter from rcu_report_unblock_qs_rnp(), which is particularly appropriate in this case given that this parameter is no longer used. Signed-off-by: -

The rcu_data_p pointer references the default set of per-CPU rcu_data structures, that is, those that call_rcu() uses, as opposed to call_rcu_bh() and sometimes call_rcu_sched(). But there is now only one set of per-CPU rcu_data structures, so that one set is by definition the default, which means that the rcu_data_p pointer no longer serves any useful purpose. This commit therefore removes it. Signed-off-by: -
