The Xeon versions of Sandy Bridge, Ivy Bridge and Haswell support an optional additional error logging mode which is enabled by an MSR. Previously, this mode was enabled from the mcelog(8) tool via /dev/cpu, but userspace should not be poking at MSRs. So move the enabling into the kernel.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
