commit 36268223c1 upstream.
As:
1) It's known that hypervisors lie about the environment anyhow (host
mismatch)
2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid
"correct" value, it all gets to be very murky when migration happens
(do you provide the "new" microcode of the machine?).
And in reality the cloud vendors are the ones that should make sure that
the microcode that is running is correct and we should just sing lalalala
and trust them.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
