Frederic Weisbecker 3352911fa9 rcu: Initialize boost kthread only for boot node prior SMP initialization 
The rcu_spawn_gp_kthread() function is called as an early initcall,
which means that SMP initialization hasn't happened yet and only the
boot CPU is online.  Therefore, create only the boost kthread for the
leaf node of the boot CPU.
