A build failure was reported when sha256() is not present:
gcc-13.1.0-nolibc/s390-linux/bin/s390-linux-ld: arch/s390/kernel/cert_store.o: in function `check_certificate_hash':
arch/s390/kernel/cert_store.c:267: undefined reference to `sha256'
Therefore make CONFIG_CERT_STORE select CRYPTO_LIB_SHA256.
Fixes: 8cf57d7217 ("s390: add support for user-defined certificates")

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.
