I've posted details on how to set up test configurations using injected HMAT
and SRAT tables here:
https://github.com/rzwisler/hmat_examples
So far I've got two different sample configs, and we can add more as they are
useful. Having the sample configs in github is also nice because if someone
finds a config that causes a kernel issue it can be reported then added to
this list of example configs for future testing.
Please let me know if you have trouble getting this working.
