The below makes more sense to me too; hmm?

This should 'obviously' have been:

		sugov_iowait_boost(j_sg_cpu, &j_util, *j_max);

Actually it should be:

 		sugov_iowait_boost(j_sg_cpu, &j_util, &j_max);

and this is how it was in the commit I reviewed from your tree. But my query
still stands, what difference will it make ?
