The NULL dereference tests in kunit_fault deliberately trigger a kernel BUG(), and therefore print the associated stack trace, even when the test passes. This is both annoying (as it bloats the test output), and can confuse some test harnesses, which assume any BUG() is a failure. Allow these tests to be specifically disabled (without disabling all of KUnit's other tests), by placing them behind the CONFIG_KUNIT_FAULT_TEST Kconfig option. This is enabled by default, but can be set to 'n' to disable the test. An empty 'kunit_fault' suite is left behind, which will automatically be marked 'skipped'. As the fault tests already were disabled under UML (as they weren't compatible with its fault handling), we can simply adapt those conditions, and add a dependency on !UML for our new option.

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 reStructuredText 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.
