rcu-tasks: Drive synchronous grace periods from calling task

Browse source

This commit causes synchronous grace periods to be driven from the task
invoking synchronize_rcu_*(), allowing these functions to be invoked from
the mid-boot dead zone extending from when the scheduler was initialized
to to point that the various RCU tasks grace-period kthreads are spawned.
This change will allow the self-tests to run in a consistent manner.
