Yeah, we can add that.

What arches should we expect this to be working on?  For starters
we'll get builds going with CONFIG_LKDTM=y, and then start looking at
adding the tests on arches that should work.

Thes will be an interesting failure modes to catch because a kernel
panic is actually a PASS, and a failure to panic is a FAIL.  :)
