The kernel test robot reports a link error when the stm driver is a
loadable module on any v5.4 kernel:
> ERROR: "__memcat_p" [drivers/hwtracing/stm/stm_core.ko] undefined!
This was fixed in mainline with commit 7273ad2b08 ("kbuild: link
lib-y objects to vmlinux forcibly when CONFIG_MODULES=y"), which
is fairly intrusive.
Fix the v5.4 specific issue with a minimal subset of that patch,
linking only the failing object into the kernel. Kernels before v4.20
are not affected.

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.
