There's lots of text here but it's a little hard to follow, this is an attempt to break it up and align its structure more closely with the code. Reword the top-level function comment to just explain what question the function answers from the point of view of the caller. Break up the internal logic into different sections that can have their own commentary describing why that part of the rationale is present. Note the page_group_by_mobility_disabled logic is not explained in the commentary, that is outside the scope of this patch...

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 reStructuredText 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.
