The invocation of do_softirq() in flush_smp_call_function_from_idle() breaks on RT because RT does not provide do_softirq().
Aside of that flush_smp_call_function_from_idle() is a misnomer since the function is invoked not only from idle, but also from the scheduler migration thread.
The following series addresses this. Changes vs. V4, which can be found here: https://lore.kernel.org/lkml/20220412203649.956258017@linutronix.de
- Fix a boatload of missing prototypes warning related to the scheduler and its header files.
Thanks,
