Couple more things. Please change the install directory name
to kselftest

tools/testing/selftests/kselftest
instead of
tools/testing/selftests/install

Also please flatten the directory structure under the install
directory. I don't see any value in creating directory for each
test for install. Also it is makes it cumbersome for users
to navigate and work with after the install. This would mean cpu
and memory hot-plug scripts need unique names.

thanks,
