This patch ("mm/vmalloc: Add interfaces to free unmapped page table") adds following 2 interfaces to free the page table in case we implement huge mapping.

pud_free_pmd_page() and pmd_free_pte_page()

Some architectures (like arm64) needs to do proper TLB maintanance after updating pagetable entry even in map. Why ? Read this, https://patchwork.kernel.org/patch/10134581/

Please add that information to the changelog.
