Hi all,

After merging the akpm-current tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

lib/vsprintf.c: In function 'ptr_to_hashval':
lib/vsprintf.c:766:14: warning: unused variable 'str' [-Wunused-variable]
  766 |  const char *str = sizeof(ptr) == 8 ? "(____ptrval____)" : "(ptrval)";
      |              ^~~

Introduced by commit

  aea87b9b95b9 ("rss_stat: add support to detect RSS updates of external mm")
