Patch series "mm/hugetlb: code refine and simplification", v4. Following are some cleanups for hugetlb. Simple testing with tools/testing/selftests/vm/map_hugetlb passes. This patch (of 7): Per my understanding, we keep the regions ordered and would always coalesce regions properly. So the task to keep this property is just to coalesce its neighbour. Let's simplify this.

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.
