Patch series "arch, mm: reduce code duplication in mem_init()", v2. Every architecture has implementation of mem_init() function and some even more than one. All these release free memory to the buddy allocator, most of them set high_memory to the end of directly addressable memory and many of them set max_mapnr for FLATMEM case. These patches pull the commonalities into the generic code and refactor some of the mem_init() implementations so that many of them can be just dropped. This patch (of 13): This will help to pull out memblock_free_all() to generic code.

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.
