The RCU-Tasks family of grace-period primitives can take some time to complete, and the amount of time can depend on the exact hardware and software configuration. Some configurations boot up fast enough that the RCU-Tasks verification process gets false-positive failures. This commit therefore allows up to 30 seconds for the grace periods to complete, with this value adjustable downwards using the rcupdate.rcu_task_stall_timeout kernel boot parameter.
