Linus Torvalds dc43fc753b - A serious scrubbing of the MTRR code including adding a new map
mechanism in order to look up the memory type of a region easily. Also
   address memory range lookup issues like returning an invalid memory
   type. Furthermore, this handles the decoupling of PAT from MTRR more
   naturally. All work by Juergen Gross

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.
