      [PATCH] fix sched_domains hotplug bootstrap ordering vs. cpu_online_map issue · c3272d7c
      William Lee Irwin III authored
      cpu_online_map is not set up at the time of sched domain initialization
      when hotplug cpu paths are used for SMP booting.
      
      At this phase of bootstrapping, cpu_possible_map can be used by the
      various architectures using cpu hotplugging for SMP bootstrap, but the
      manipulations of cpu_online_map done on behalf of NUMA architectures,
      done indirectly via node_to_cpumask(), can't, because cpu_online_map
      starts depopulated and hasn't yet been populated.
      
      On true NUMA architectures this is a distinct cpumask_t from
      cpu_online_map and so the unpatched code works on NUMA; on non-NUMA
      architectures the definition of node_to_cpumask() this way breaks and
      would require an invasive sweeping of users of node_to_cpumask() to
      change it to e.g.  cpu_possible_map, as cpu_possible_map is not suitable
      for use at runtime as a substitute for cpu_online_map.
