    Results from Linaro’s test farm.
    Regressions detected on x86_64 and i386.

    Test failure output:
    CVE-2017-5715: VULN (IBRS+IBPB or retpoline+IBPB+RSB filling, is
    needed to mitigate the vulnerability)

    Test description:
    CVE-2017-5715 branch target injection (Spectre Variant 2)

    Impact: Kernel
    Mitigation 1: new opcode via microcode update that should be used by
    up to date compilers to protect the BTB (by flushing indirect branch
    predictors)
    Mitigation 2: introducing "retpoline" into compilers, and recompile
    software/OS with it
    Performance impact of the mitigation: high for mitigation 1, medium
    for mitigation 2, depending on your CPU
