    kernel/padata.c: hide unused functions · 19d795b6
    Arnd Bergmann authored
    A recent cleanup removed some exported functions that were not used
    anywhere, which in turn exposed the fact that some other functions in
    the same file are only used in some configurations.
    
    We now get a warning about them when CONFIG_HOTPLUG_CPU is disabled:
    
      kernel/padata.c:670:12: error: '__padata_remove_cpu' defined but not used [-Werror=unused-function]
       static int __padata_remove_cpu(struct padata_instance *pinst, int cpu)
                  ^~~~~~~~~~~~~~~~~~~
      kernel/padata.c:650:12: error: '__padata_add_cpu' defined but not used [-Werror=unused-function]
       static int __padata_add_cpu(struct padata_instance *pinst, int cpu)
    
    This rearranges the code so the __padata_remove_cpu/__padata_add_cpu
    functions are within the #ifdef that protects the code that calls them.
