Fedora 32: 2020-1afbe7ba2d Critical Microcode Update for System Hangs

The microcode_ctl utility is a companion to the microcode driver written

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.
