Do you mean "tools/testing/selftest/Makefile"? I try to do it but I could not
get the objtree and srctree if it is called directly(objtree and srctree is
defined in toplevel Makefile)
> make -C tools/testing/selftests kselftest-mergeconfig
make: Entering directory
'/home/bamvor/works/source/kernel/linux/tools/testing/selftests'
Makefile:112: *** No .config exists, config your kernel first!.  Stop.
make: Leaving directory
'/home/bamvor/works/source/kernel/linux/tools/testing/selftests'

Suggestions?
