Because memory-less node's ->node_present_pages and its zone's ->present_pages are all 0, the judgement before calling node_set_state() to set N_MEMORY, N_HIGH_MEMORY, N_NORMAL_MEMORY for node is enough to skip memory-less node. The 'continue;' statement inside for_each_node() loop of free_area_init() is gilding the lily. Here, remove the special handling to make memory-less node share the same code flow as normal node. And also rephrase the code comments above the 'continue' statement and move them above above line 'if (pgdat->node_present_pages)'.

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.
