Add the test counts to the JSON output from kunit.py. For example:
...
"git_branch": "kselftest",
"misc":
{
"tests": 2,
"passed": 1.
"failed": 1,
"crashed": 0,
"skipped": 0,
"errors": 0,
}
...
To output the JSON using the following command:
./tools/testing/kunit/kunit.py run example --json
This has been requested by KUnit users. The counts are in a "misc"
field because the JSON output needs to be compliant with the KCIDB
submission guide. There are no counts fields but there is a "misc" field
in the guide.

The documentation on testing static functions using the KUnit macros
VISIBLE_IF_KUNIT and EXPORT_SYMBOL_IF_KUNIT is lacking clarity and
missing key steps in the example. This has caused bugs and confusion
among developers.
Improve wording of description and add missing steps to the example.
This entails adding the "#include <kunit/visibility.h>" line and the
"MODULE_IMPORT_NS(EXPORTED_FOR_KUNIT_TESTING);" line. Both of which were
missing from the original example and key to exposing static functions.

In preparation for making the kmalloc family of allocators type aware,
we need to make sure that the returned type from the allocation matches
the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct kunit_suite **" but the returned type will
be "struct kunit_suite * const *". Since it isn't generally possible
to remove the const qualifier, adjust the allocation type to match
the assignment.

The 32-bit sparc configuration (--arch sparc) crashes on
the kunit_fault_test. It's known that some architectures don't handle
deliberate segfaults in kernel mode well, so there's a config switch to
disable tests which rely upon it by default.
Use this for the sparc config, making sure the default config for it
passes.
