This series is primarily code movement for RCU CPU stall warnings. If I am having a hard time finding the various scattered pieces of this code, it is in need of consolidation! 1-3. Move RCU CPU stall-warning code into kernel/rcu/tree_stall.h. 4. Inline RCU task stall-warning helper functions. 5. Move rcu_print_task_exp_stall() to tree_exp.h. 6. Inline RCU stall-warning info helper functions. 7. Move FAST_NO_HZ stall-warning code to tree_stall.h. 8. Organize functions in tree_stall.h. 9. Move irq-disabled stall-warning checking to tree_stall.h. 10. Move forward-progress checkers into tree_stall.h 11. Fix nohz status in stall warning, courtesy of Neeraj Upadhyay.
