Instead of initializing them to uncached, let's set them to PTE for kernel tracking. While at it do some minor adjustments to comments and coding style. From Chris: "What it does mean is that the buffer contents are consistent with our cache tracking; and for userspace the results were always undefined. So we should at least be able to guarantee that the data written by userspace from the CPU is visible. After that, your caches are on your own".

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.
