Applied to arm64 (for-next/tlbi), thanks!
[3/6] arm64: Add tlbi_user_level TLB invalidation helper
https://git.kernel.org/arm64/c/e735b98a5fe0
[4/6] tlb: mmu_gather: add tlb_flush_*_range APIs
https://git.kernel.org/arm64/c/2631ed00b049
[5/6] arm64: tlb: Set the TTL field in flush_tlb_range
https://git.kernel.org/arm64/c/c4ab2cbc1d87
[6/6] arm64: tlb: Set the TTL field in flush_*_tlb_range
https://git.kernel.org/arm64/c/a7ac1cfa4c05
I haven't included the first 2 patches as I rebased the above on top of
Marc's TTL branch:
