It's not solved, this report was closed as a duplicate:

This is the known "Terminator issue" in Cycles (also some other engines have trouble here).
It's a known issue and will probably be improved one day, but not considered a bug at the moment. In the meantime, the only way to avoid this, is to use high-res geometry.

OK. Thank you, Brecht. I hope this issue will be fixed soon.
