Applied to arm64 (for-next/tlbi), thanks!

[1/3] arm64: tlb: Detect the ARMv8.4 TLBI RANGE feature
      https://git.kernel.org/arm64/c/b620ba54547c
[2/3] arm64: enable tlbi range instructions
      https://git.kernel.org/arm64/c/7c78f67e9bd9
[3/3] arm64: tlb: Use the TLBI RANGE feature in arm64
      https://git.kernel.org/arm64/c/d1d3aa98b1d4

(I introduced a system_supports_tlb_range() to avoid the IS_ENABLED
twice)
