Hi Viresh,
We are still waiting for some workload automation test results before we can
decide. Sorry I haven't replied yet to your other email, but we don't have
the bandwidth in ARM at the moment to run the tests, so it will fall into
your lap (or someone inside Linaro) to do the tests before we enable it.
I want to see the impact of the patch before deciding.
Regards,
Liviu
