Kefeng Wang 01152bd2e4 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.
