Subjectlinux-next: build warning after merge of the akpm tree
Hi all,

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

mm/hmm.c: In function 'hmm_vma_walk_pud':
mm/hmm.c:478:9: warning: unused variable 'pmdp' [-Wunused-variable]
478 | pmd_t *pmdp;
| ^~~~
mm/hmm.c:477:30: warning: unused variable 'next' [-Wunused-variable]
477 | unsigned long addr = start, next;
| ^~~~

Introduced by commit
