Fedora: FEDORA-2020-e8835a5f8e Critical: Microcode Patch for CPU Security

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.
