H A D | smp.h | fa26d0c7 Tue Apr 06 10:56:40 CDT 2021 Vitaly Kuznetsov <vkuznets@redhat.com> ACPI: processor: Fix build when CONFIG_ACPI_PROCESSOR=m
Commit 8cdddd182bd7 ("ACPI: processor: Fix CPU0 wakeup in acpi_idle_play_dead()") tried to fix CPU0 hotplug breakage by copying wakeup_cpu0() + start_cpu0() logic from hlt_play_dead()//mwait_play_dead() into acpi_idle_play_dead(). The problem is that these functions are not exported to modules so when CONFIG_ACPI_PROCESSOR=m build fails.
The issue could've been fixed by exporting both wakeup_cpu0()/start_cpu0() (the later from assembly) but it seems putting the whole pattern into a new function and exporting it instead is better.
