So this set happens to have more changes than expected because I found out that the timer list full nohz kick also relies on the scheduler IPI. So I had to convert it as well, hence a few more change splitups.
Changes:
* Check also raised lists from irq_work_needs_cpu() (thanks Peterz)
* Comment on SMP functions priority in generic_smp_call_function_single_interrupt() because IPI callbacks there are often synchronous as opposed to irq works. (thanks Peterz)
* s/native_send_call_func_single_ipi/native_send_call_func_single_ipi (thanks Eric Dumazet)
* Only build irq_work_queue_on() on CONFIG_SMP, fixes some broken builds
* Convert full nohz timer list kick
