This commit adds expedited grace-period functionality to RCU's polled grace-period API, adding start_poll_synchronize_rcu_expedited() and cond_synchronize_rcu_expedited(), which are similar to the existing start_poll_synchronize_rcu() and cond_synchronize_rcu() functions, respectively. Note that although start_poll_synchronize_rcu_expedited() can be invoked very early, the resulting expedited grace periods are not guaranteed to start until after workqueues are fully initialized. On the other hand, both synchronize_rcu() and synchronize_rcu_expedited() can also be invoked very early, and the resulting grace periods will be taken into account as they occur.
