Maybe if tools doesn't sounds right, we could move testing from under tools
and have it be testing

We have several selftests spread around in the kernel tree. It makes it easier
to pull them under a single make target devtest. I sent in a patch add devtest
target that runs tests that are under tools/testing/selftests a couple of
weeks ago, hopefully it will be included in 3.17. I am working towards pulling
more kernel selftests that exist under this devtest umbrella. That is
the motivation
behind starting this conversation. :)
