Fedora: 2020-d5941ea479 Critical: CPU Microcode Update and System Hang Fix

The microcode_ctl utility is a companion to the microcode driver written

by Tigran Aivazian .

The microcode update is volatile and needs to be uploaded on each system

boot i.e. it doesn't reflash your cpu permanently, reboot and it reverts

back to the old microcode.
