Subject: [PATCH v2 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.
Thanks,
Bang
Changes since v1 [1]:
- Add __HAVE_ARCH_UPDATE_MMU_TLB_RANGE macro (per Lance Yang)
