Subject[PATCH] mm: pagewalk: fix unused variable warning
Date
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.

Fixes: cb4d03d5fb4c ("mm: pagewalk: add p4d_entry() and pgd_entry()")
