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/

Pass 'addr' in these interfaces so that proper TLB ops
can be performed.
