Patch series "mm/init: minor clean up and improvement". These are all observed when going through code flow during mm init. This patch (of 7): When CONFIG_SPARSEMEM_EXTREME is enabled, mem_section need be initialized to point at a two-dimensional array, and its 1st dimension of length NR_SECTION_ROOTS will be dynamically allocated. Once the allocation is done, it's available for all nodes. So take the 1st dimension of mem_section initialization out of memory_present()(), and put it into memblocks_present() which is a more appripriate place.

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.
