Description

https://lists.debian.org/debian-devel/2017/06/msg00308.html

Unfixed Skylake and Kaby Lake processors could, in some
situations, dangerously misbehave when hyper-threading is enabled.

The latest microcode from Intel fixes the issue presented in the link for two processor model.

Debian includes the fix in the "intel-microcode" package and our customer was wondering whether we include anything similar.(For both wrl6 and wrl8). The updated microcode does not include a fix for Kaby Lake.
