commit 53036937a101b5faeaf98e7438555fa854a1a844 upstream.
Including m68k's <asm/raw_io.h> in vga.h on nommu platforms results
in conflicting defines with io_no.h for various I/O macros from the
__raw_read and __raw_write families. An example error is

Include <asm/io.h>, which avoids raw_io.h on nommu platforms.
Also change the defined values of some of the read/write symbols in
vga.h to __raw_read/__raw_write as the raw_in/raw_out symbols are not
generally available.

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.
