Uladzislau Rezki (Sony) 462df2f543 rcu: Support direct wake-up of synchronize_rcu() users
This patch introduces a small enhancement which allows to do a
direct wake-up of synchronize_rcu() callers. It occurs after a
completion of grace period, thus by the gp-kthread.

Number of clients is limited by the hard-coded maximum allowed
threshold. The remaining part, if still exists is deferred to
a main worker.
