Add helpers to identify CTL (control) and STATUS MCi MSR types instead of open coding the checks using the offset. Using the offset is perfectly safe, but unintuitive, as understanding what the code does requires knowing that the offset calcuation will not affect the lower three bits. Opportunistically comment the STATUS logic to save readers a trip to Intel's SDM or AMD's APM to understand the "data != 0" check. No functional change intended.

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.
