- Provide kernel entry/exit hooks necessary for userspace
- RCU extended quiescent state. Syscalls need to be wrapped inside
- rcu_user_exit()-rcu_user_enter() through the slow path using
- TIF_NOHZ flag. Exceptions handlers must be wrapped as well. Irqs
- are already protected inside rcu_irq_enter/rcu_irq_exit() but
- preemption or signal handling on irq exit still need to be protected.
