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
