How to counter the Meltdown and specter security flaws

Unless you have been avoiding all news lately, you have no doubt seen or heard countless reports on two security flaws discovered in Intel, AMD and Arm processors. These, combined, affect pretty much everything built in the last 15 years or so. Without going into all the details, reports appear to indicate that the only real fix is a hardware replacement. The hardware fix isn’t available, so patches and fixes are being released to prevent someone from getting access to the process that accidentally leaks data.

Here are the fixes available and where to get them for the second week of January 2018
