[PATCH 0/2] arm64: spectre-v1 write fixes (CVE-2018-3693)

[Mark Rutland]

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.
