rcu: Defer rcu_tasks_kthread() creation till first call_rcu_tasks()
It is expected that many sites will have CONFIG_TASKS_RCU=y, but will never actually invoke call_rcu_tasks(). For such sites, creating rcu_tasks_kthread() at boot is wasteful. This commit therefore defers creation of this kthread until the time of the first call_rcu_tasks(). This of course means that the first call_rcu_tasks() must be invoked from process context after the scheduler is fully operational. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
