#     
#     Pull more Kunit updates from Shuah Khan:
#     
#      - add Kunit to kernel_init() and remove KUnit from init calls entirely.
#     
#        This addresses the concern that Kunit would not work correctly during
#        late init phase.
#     
#      - add a linker section where KUnit can put references to its test
#        suites.
#     
#        This is the first step in transitioning to dispatching all KUnit
#        tests from a centralized executor rather than having each as its own
#        separate late_initcall.
#     
#      - add a centralized executor to dispatch tests rather than relying on
#        late_initcall to schedule each test suite separately. Centralized
#        execution is for built-in tests only; modules will execute tests when
#        loaded.
#     
#      - convert bitfield test to use KUnit framework
#     
#      - Documentation updates for naming guidelines and how
#        kunit_test_suite() works.
#     
#      - add test plan to KUnit TAP format
