Subject: linux-next: build warning after merge of the akpm-current tree

Hi all,

After merging the akpm-current tree, today's linux-next build (i386
defconfig) produced this warning:

mm/hugetlb.c: In function 'huge_pte_offset':
cc1: warning: function may return address of local variable [-Wreturn-local-addr]
mm/hugetlb.c:5361:14: note: declared here
 5361 |  pud_t *pud, pud_entry;
      |              ^~~~~~~~~
cc1: warning: function may return address of local variable [-Wreturn-local-addr]

 5360 |  p4d_t *p4d, p4d_entry;
      |              ^~~~~~~~~
