RFC: Speculative Load Hardening (a Spectre variant #1 mitigation)
Hello all,
I've been working for the last month or so on a comprehensive mitigation
approach to variant #1 of Spectre. There are a bunch of reasons why this is
desirable:
- Critical software that is unlikely to be easily hand-mitigated (or where
the performance tradeoff isn't worth it) will have a compelling option.
- It gives us a baseline on performance for hand-mitigation.
- Combined
