commit 9129886b88 upstream.
With huge kernel pages, we randomly eat a SPARC in map_pages(). This
is fixed by dropping __init from the declaration.
However, map_pages references the __init routine memblock_alloc_try_nid
via memblock_alloc. Thus, it needs to be marked with __ref.
memblock_alloc is only called before the kernel text is set to readonly.
The __ref on free_initmem is no longer needed.
Comment regarding map_pages being in the init section is removed.

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.
