For reasons I cannot understand, m68k moves the start of the stack frame for consecutive calls to the same function if the function's test variable is larger than 8 bytes. This was only happening for the char array test (obviously), so adjust the length of the string for m68k only. I want the array size to be longer than "unsigned long" for every given architecture, so the other remain unchanged. Additionally adjust the error message to be a bit more clear about what's happened, and move the KUNIT check outside of the consecutive calls to minimize what happens between them.

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.
