Probably worth adding something like: "By default, irq_work is tied to the tick processing (update_process_times()) but in full NOHZ mode, no tick means no IRQ work. In order for IRQ work to be done in full NOHZ mode, a self-IPI is used to process IRQ work." Other than the changelog nit, patch looks good, feel free to add Reviewed-by: Kevin Hilman If Russell is OK with this, it can go to his patch system. Kevin
