Add defconfig for UML and a fragment that can be used to configure other architectures for building KUnit tests. Add option to kunit_tool to use a defconfig to create the kunitconfig.
Signed-off-by: Brendan Higgins brendanhiggins@google.com --- Changes Since Last Version - This patch is new adding default configs to build KUnit. - NOTE: there is still some discussion to be had here about whether we should go with a defconfig, a config fragment, or both. --- arch/um/configs/kunit_defconfig | 8 ++++++++ tools/testing/kunit/configs/all_tests.config | 8 ++++++++ tools/testing/kunit/kunit.py | 17 +++++++++++++++-- tools/testing/kunit/kunit_kernel.py | 3 ++- 4 files changed, 33 insertions(+), 3 deletions(-) create mode 100644 arch/um/configs/kunit_defconfig create mode 100644 tools/testing/kunit/configs/all_tests.config
