Subject: mm: hugetlb_vmemmap: move alloc_vmemmap_page_list() next to its free helper
Date: Wed, 04 Nov 2026 10:35:06 +0800

Keep alloc_vmemmap_page_list() together with free_vmemmap_page_list(). 
This also allows the folio-oriented optimization helper introduced in a
subsequent change to reuse the allocator without a forward declaration.

No functional change intended.
