Component Type: kbuild config
More info: Provide kernel/user boundaries probes necessary for subsystems that need it, such as userspace RCU extended quiescent state. Syscalls need to be wrapped inside user_exit()-user_enter(), either optimized behind static key or 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.
