Anatol Pomozov 85f58908c0 cfq: explicitly use 64bit divide operation for 64bit arguments ... commit f3cff25f05f2ac29b2ee355e611b0657482f6f1d upstream. 'samples' is 64bit operant, but do_div() second parameter is 32. do_div silently truncates high 32 bits and calculated result is invalid. In case if low 32bit of 'samples' are zeros then do_div() produces kernel crash.
