(1) Replace nid_to_addroffset() with nid_to_addrbase() and then remove the
related useless code.
(2) Since end_pfn = start_pfn + node_psize, use "node_psize" instead of
"end_pfn - start_pfn" to avoid the redundant calculation.
(3) After commit 6fbde6b492 ("MIPS: Loongson64: Move files to the
top-level directory"), CONFIG_ZONE_DMA32 is always set for Loongson64
due to MACH_LOONGSON64 selects ZONE_DMA32, so no need to use ifdef any
more, just remove it.

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.
