Subject[patch V5 0/3] smp: Make softirq handling RT friendly
Date
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,

tglx
