This update for kernel-firmware fixes the following issues :
This new firmware disables branch prediction on AMD family 17h processor to mitigate an attack on the branch predictor that could lead to information disclosure from e.g. kernel memory (bsc#1068032 CVE-2017-5715).
This update was imported from the SUSE:SLE-12-SP2:Update update project.
