It ensures that possible_cpus contains complete mapping if numa is enabled by the time machine_init() is executed. As result non completely mapped CPUs: 1) appear in ACPI/fdt blobs 2) QMP query-hotpluggable-cpus command shows bound nodes for such CPUs 3) allows to drop checks for has_node_id in numa only code, reducing number of invariants incomplete mapping could produce 4) moves fixup/implicit node init from runtime numa_cpu_pre_plug() (when CPU object is created) to machine_numa_finish_init() which helps to fix [1, 2] and make possible_cpus complete source of numa mapping available even before CPUs are created.
