Subject: [PATCH 0/3] drop hugetlb_free_pgd_range()

For all architectures that support hugetlb except for sparc,
hugetlb_free_pgd_range() just calls free_pgd_range(). It turns out
the sparc implementation is essentially identical to free_pgd_range()
and can be removed. Remove it and update free_pgtables() to treat
hugetlb VMAs the same as others.

Anthony Yznaga (3):
  sparc64: remove hugetlb_free_pgd_range()
  mm: remove call to hugetlb_free_pgd_range()
  mm: drop hugetlb_free_pgd_range()
