I discussed this a bit with Metan. We think it would be fairly trivial
to create an LTP wrapper for these.

So we just create an LTP test which forks and execs one of these
reproducers then checks for kernel taints after the child completes or
is killed. It can take the reproducer path as an argument and we can
generate a runtest file with all the reproducers in that we are able to
compile.

I imagine a lot of these reproducers will not work on older kernels, so
this would just be a best efforts basis. We would ignore any problems
during execution unless there is a kernel error.

This should work with existing LTP runners with maybe a minor change or
two to building and configuration.

I will start experimenting with this and post the results to the LTP
mailing list.
