This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. Depends on [1]. Changes since v2: - Due to Alan's changes in [1], KUnit can be built as a module. - The name of the tests that could not be run with KUnit has been changed to be more generic: test_kasan_module. - Documentation on how to run the new KASAN tests and what to expect when running them has been added. - Some variables and functions are now static. - Now save/restore panic_on_warn in a similar way to kasan_multi_shot and renamed the init/exit functions to be more generic to accommodate. - Due to [2] in kasan_strings, kasan_memchr, and kasan_memcmp will fail if CONFIG_AMD_MEM_ENCRYPT is enabled so return early and print message explaining this circumstance. - Changed preprocessor checks to C checks where applicable.
