rcu: Fix outdated hotplug-exclusion comment in rcu_gp_init()
In the past, RCU grace-period initialization excluded CPU-hotplug operations, but this is no longer the case. This commit therefore removed an outdated comment in rcu_gp_init() claiming that these are excluded. Reported-by: Lihao Liang <lihao.liang@gmail.com> Signed-off-by: Paul E.
