These patches inhibit spectre-v1-write gadgets found in arch/arm64, using the same mitigation applied to existing spectre-v1-read gadgets.
This issue is also known as CVE-2018-3693, or "bounds check bypass store". More details can be found in the Arm Cache Speculation Side-channels whitepaper, available from the Arm security updates site [1].
Thanks, Mark.
