Hello!
This series contains RCU-Tasks updates, including some -rt fixups,

race-condition failure.
1. rcu-tasks: Fix race in schedule and flush work, courtesy of
Padmanabha Srinivasaiah.
2. rcu-tasks: Print pre-stall-warning informational messages.
3. rcu-tasks: Use rcuwait for the rcu_tasks_kthread(), courtesy of
Sebastian Andrzej Siewior.
4. rcu-tasks: Make Tasks RCU account for userspace execution.
5. rcu-tasks: Use schedule_hrtimeout_range() to wait for grace
periods, courtesy of Sebastian Andrzej Siewior.
6. rcu-tasks: Restore use of timers for non-RT kernels.
7. rcu-tasks: Make show_rcu_tasks_generic_gp_kthread() check
all CPUs.
8. rcu-tasks: Handle sparse cpu_possible_mask, courtesy of Eric
Dumazet.
9. rcu-tasks: Handle sparse cpu_possible_mask in
rcu_tasks_invoke_cbs().
Thanx, Paul
