on i386:

when MEMORY_HOTPLUG is not set and NUMA is not set:

../drivers/nvdimm/e820.c: In function ‘e820_register_one’:
../drivers/nvdimm/e820.c:24:12: error: implicit declaration of function ‘phys_to_target_node’; did you mean ‘set_page_node’? [-Werror=implicit-function-declaration]
  int nid = phys_to_target_node(res->start);
            ^~~~~~~~~~~~~~~~~~~

In include/linux/memory_hotplug.h, phys_to_target_node() is hidden inside
CONFIG_MEMORY_HOTPLUG.
