Compiling with e.g MARCH=z900 results in compile errors:
arch/s390/lib/uaccess.c: In function 'copy_from_user_mvcos':
>> arch/s390/lib/uaccess.c:65:15: error: variable 'spec' has initializer but incomplete type
65 | union oac spec = {
Therefore make definition of union oac visible for all MARCHs.

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.
