Hi all,

After merging the akpm-current tree, today's linux-next build (x86_64
allnoconfig) produced this warning:

mm/sparse.c:311:12: warning: 'fill_subsection_map' defined but not used [-Wunused-function]
  311 | static int fill_subsection_map(unsigned long pfn, unsigned long nr_pages)
      |            ^~~~~~~~~~~~~~~~~~~
mm/sparse.c:306:13: warning: 'is_subsection_map_empty' defined but not used [-Wunused-function]
  306 | static bool is_subsection_map_empty(struct mem_section *ms)
      |             ^~~~~~~~~~~~~~~~~~~~~~~
mm/sparse.c:301:12: warning: 'clear_subsection_map' defined but not used [-Wunused-function]
  301 | static int clear_subsection_map(unsigned long pfn, unsigned long nr_pages)

Introduced by commits

  38eb09ac7c29 ("mm/sparse.c: introduce new function fill_subsection_map()")
  334411156ba6 ("mm/sparse.c: introduce a new function clear_subsection_map()")

Or maybe laster patches.
