ACPI: processor: Only call arch_unregister_cpu() if HOTPLUG_CPU is selected
The kbuild robot points out that configurations without HOTPLUG_CPU
selected can try to build acpi_processor_post_eject() without success
as arch_unregister_cpu() is not defined.
Check this explicitly. This will be merged into:
| ACPI: Add post_eject to struct acpi_scan_handler for cpu hotplug
for any subsequent posting.
