All the comments which explains how HVO works are moved to
vmemmap_dedup.rst since
commit 4917f55b4e ("mm/sparse-vmemmap: improve memory savings for compound devmaps")
except some comments above page_fixed_fake_head(). This commit moves
those comments to vmemmap_dedup.rst and improve vmemmap_dedup.rst as well.

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.
