Bang Li 23b1b44e6c mm: add update_mmu_tlb_range() 
Patch series "Add update_mmu_tlb_range() to simplify code", v4.

This series of commits mainly adds the update_mmu_tlb_range() to batch
update tlb in an address range and implement update_mmu_tlb() using
update_mmu_tlb_range().

After commit 19eaf44954 ("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.


This patch (of 3):

Add update_mmu_tlb_range(), we can batch update tlb of an address range.
