Mitigate speculative execution side-channel vulnerabilities

Seems the new year bring us some bad surprises in terms of security. There has been some rumors and now turned out to be truth that certain processors are vulnerable to certain attacks. Yes processors. That means that affects a wide variety of Operating Systems. As Microsoft puts it:
