-Subject: [PATCH] smp: Process pending softirqs in
- flush_smp_call_function_from_idle()
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.17-rt32.tar.xz
-
-send_call_function_single_ipi() may wake an idle CPU without sending an
-IPI. The woken up CPU will process the SMP-functions in
-flush_smp_call_function_from_idle(). Any raised softirq from within the
-SMP-function call will not be processed.
-Should the CPU have no tasks assigned, then it will go back to idle with
-pending softirqs and the NOHZ will rightfully complain.
-
-Process pending softirqs on return from flush_smp_call_function_queue().
-
-Fixes: b2a02fc43a1f4 ("smp: Optimize send_call_function_single_ipi()")
