This update for ucode-intel fixes the following issues:

The CPU microcode for Haswell-X, Skylake-X and Broadwell-X chipsets
was updated to report both branch prediction control via CPUID flag and
ability to control branch prediction via an MSR register.

This update is part of a mitigation for a branch predictor based
information disclosure attack, and needs additional code in the Linux
Kernel to be active (bsc#1068032 CVE-2017-5715)
