mm: debug_vm_pgtable: add debug_vm_pgtable_free_huge_page()
Patch series "mm: hugetlb: allocate frozen gigantic folio", v6.
Introduce alloc_contig_frozen_pages() and cma_alloc_frozen_compound()
which avoid atomic operation about page refcount, and then convert to
allocate frozen gigantic folio by the new helpers in hugetlb to cleanup
the alloc_gigantic_folio().
This patch (of 6):
Add a new helper to free huge page to be consistency to
debug_vm_pgtable_alloc_huge_page(), and use HPAGE_PUD_ORDER instead of
open-code.
Also move the free_contig_range() under CONFIG_ALLOC_CONTIG since all
caller are built with CONFIG_ALLOC_CONTIG.
