After the commit 19eaf44954df ("mm: thp: support allocation of anonymous multi-size THP"), We may need to batch update tlb of a certain address range by calling update_mmu_tlb() in a loop. Using the update_mmu_tlb_range(), we can simplify the code and possibly reduce the execution of some unnecessary code in some architectures.
