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. V3, which can be found
here: https://lore.kernel.org/lkml/[email protected]
- Rename flush_smp_call_function_from_idle() and add comments
- Confine the RT specifics in the softirq code
Thanks,
