Integrates UBSAN into the KUnit testing framework. It fails KUnit tests whenever it reports undefined behavior. When CONFIG_KUNIT=n, nothing is printed or even formatted, so this has no behavioral impact outside of tests. kunit_fail_current_test() effectively does a pr_err() as well, so there's some slight duplication, but it also ensures an error is recorded in the debugfs entry for the running KUnit test. Print a shorter version of the message to make it less spammy.

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.
