Over the past couple of years, the generic mmu_gather gained range tracking - 597e1c35 (mm/mmu_gather: enable tlb flush range in generic mmu_gather), 2b047252 (Fix TLB gather virtual address range invalidation corner cases) - and tlb_fast_mode() has been removed - 29eb7782 (arch, mm: Remove tlb_fast_mode()). The new mmu_gather structure is now suitable for arm64 and this patch converts the arch asm/tlb.h to the generic code. One functional difference is the shift_arg_pages() case where previously the code was flushing the full mm (no tlb_start_vma call) but now it flushes the range given to tlb_gather_mmu() (possibly slightly more efficient previously).
