Not to mention that Spectre variants affected AMD, ARM & IBM (at least). This publicly NSA funded research ("The Intel 80x86 processor architecture: pitfalls for secure systems") from 1995 has an interesting section: https://ieeexplore.ieee.org/document/398934/ https://pdfs.semanticscholar.org/2209/42809262c17b6631c0f6536c91aaf7756857.pdf Section 3.10 - Cache and TLB timing channels which warns (in generalities) about the use of MSRs and the use of instruction timing as side channels.
