From the code it looks good, but to be honest I don't think that this
makes much sense from the organizational point of view.
If a self test exercises internals of TTM it should be moved into TTM
as well.
This particular selftest actually exercises i915 memory regions which is
a level above TTM, but the memory regions are backed by TTM. Since they
are mock selftests they don't have a TTM device. For the buddy allocator
the situation would be the same, but there we have selftests that
exercise the allocator standalone, and those would probably fit best
into a TTM selftest infrastructure.
Although in this particular case, we could of course add a mock TTM
device and be done. Pls let me know what you think.
