All supported CPUs other than the old dragonball and in theory other 68000 derivatives use the include/linux/unaligned/access_ok.h implementation for accessing unaligned variables, so presumably this works everywhere. However, m68k never selects CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS, so none of the other conditionals in the kernel get the optimized implementation. Select this based on CPU_HAS_NO_UNALIGNED to make the two settings always match, and then use the generic version of the header.

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.
