Subject: [PATCH v1 0/5] Add update_mmu_tlb_range() to simplify code

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

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.

Bang Li (5):
  LoongArch: Add update_mmu_tlb_range()
  mips: Add update_mmu_tlb_range()
  riscv: Add update_mmu_tlb_range()
  xtensa: Add update_mmu_tlb_range()
  mm: Add update_mmu_tlb_range()
