I had sent mail about this before, but did not hear a response, so I am not sure what to next. I had seen in the past there was a similar error for blackfin and someone submitted a patch https://lkml.org/lkml/2015/4/5/4 to add __ucmpdi2. Were there issues with that patch or did you guys want it fixed differently?
