Blackfin is still maintained by Steven Miao right?

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?
