The tagged-address-abi.rst patch (2/3) has been queued in the arm64 for-next/core tree. There is only one patch left in this series (keeping the cover letter for consistency). Changes in v10: - Remove the tag preservation paragraph since the new ABI does not change the behaviour we already have. The only difference is that now the kernel can access tagged addresses (e.g. delivering a signal on a tagged alternate stack).
