One of the pagewalk patches introduced a harmless warning:
mm/hmm.c: In function 'hmm_vma_walk_pud': mm/hmm.c:478:9: error: unused variable 'pmdp' [-Werror=unused-variable] pmd_t *pmdp; ^~~~ mm/hmm.c:477:30: error: unused variable 'next' [-Werror=unused-variable] unsigned long addr = start, next; ^~~~
Remove both of the now-unused variables.
