Oscar Salvador bbe5d9939e mm/page_alloc.c: drop uneeded __meminit and __meminitdata 
Since commit 03e85f9d5f ("mm/page_alloc: Introduce
free_area_init_core_hotplug"), some functions changed to only be called
during system initialization.  Concretly, free_area_init_node() and the
functions that hang from it.

Also, some variables are no longer used after the system has gone
through initialization.  So this could be considered as a late clean-up
for that patch.

This patch changes the functions from __meminit to __init, and the
variables from __meminitdata to __initdata.

In return, we get some KBs back:

Before:
  Freeing unused kernel image memory: 2472K

After:
  Freeing unused kernel image memory: 2480K

README 

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.
