The code that handles the early fdt mapping is hard to read and does not create the same mapping size depending on the kernel: - for 64-bit, 2 PMD entries are used which amounts to a 4MB mapping - for 32-bit, 2 PGDIR entries are used which amounts to a 8MB mapping So keep using 2 PMD entries for 64-bit and use only one PGD entry for 32-bit needed to cover 4MB. Move that into a new function called create_fdt_early_page_table which, using the same naming as create_kernel_page_table.

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.
