With that change, FWIW: Reviewed-by: Dave Martin <Dave.Martin@arm.com> (i.e., this looks reasonable, but I'm not a kselftest expert...) [...] Cheers ---Dave

Modify KSFT arm64 toplevel Makefile to maintain arm64 kselftests organized by subsystem, keeping them into distinct subdirectories under arm64 custom KSFT directory: tools/testing/selftests/arm64/ Add to such toplevel Makefile a mechanism to guess the effective location of Kernel headers as installed by KSFT framework. Fit existing arm64 tags kselftest into this new schema moving them into their own subdirectory (arm64/tags).
