Subject: [PATCH 0/5] Lock warning clean up 

This patch series adds missing annotations to functions that register warnings of context imbalance when built with Sparse tool.
The adds fix these warnings and give insight on what the functions are actually doing.
In the core kernel,

1. IRQ and RCU subsystems: exactly patch 1 and 3,  __releases() annotations were added as these functions exit the critical section
2. RCU subsystem again, patch 2 and 4, __acquire() annotations were added as the functions allow entry to the critical section.
3. TIME subsystem, patch 5 where lock is held at entry and exit of the function, an __must_hold() annotation was added.

Jules Irenge (5):
  irq: Add  missing annotation for __irq_put_desc_unlock()
  rcu: Add missing annotation for exit_tasks_rcu_start()
  rcu: Add missing annotation for exit_tasks_rcu_finish()
  rcu: Add missing annotation for rcu_nocb_bypass_lock()
  time: Add missing annotation for __run_timer()
