Cache binning is a page allocation strategy intended to improve performance in a cache-organized memory system. It is not the same thing as a cache line. In doing a little background for this reply, I ran across this paper: http://d3s.mff.cuni.cz/publications/HockoKalibera-Submitted.pdf, which gives an adequate description of cache binning, but also concludes that their experiments with it did not improve general Linux performance on a suite of applications, though there were particular applications that were helped. I can't speak to the quality of the paper itself, but its conclusions are consistent with my understanding.
