      arm64: Call numa_store_cpu_info() earlier. · c18df0ad
      David Daney authored
      The wq_numa_init() function makes a private CPU to node map by calling
      cpu_to_node() early in the boot process, before the non-boot CPUs are
      brought online.  Since the default implementation of cpu_to_node()
      returns zero for CPUs that have never been brought online, the
      workqueue system's view is that *all* CPUs are on node zero.
      
      When the unbound workqueue for a non-zero node is created, the
      tsk_cpus_allowed() for the worker threads is the empty set because
      there are, in the view of the workqueue system, no CPUs on non-zero
      nodes.  The code in try_to_wake_up() using this empty cpumask ends up
      using the cpumask empty set value of NR_CPUS as an index into the
      per-CPU area pointer array, and gets garbage as it is one past the end
      of the array.  This results in:

      Fix by moving call to numa_store_cpu_info() for all CPUs into

      smp_store_cpu_info() now contains only a single function call,
      simplify by removing the function and out-lining its contents.
