If anyone has any objections, please let me know. =============== commit cc904f9cf26dc455cffbdf6e7eb86717e047d8ff upstream. A new limit selected arbitrarily as power of two greater than required minimum for Xeon Phi processor (72 for Knights Landing). Currently driver is not able to handle cores with core ID greater than 32.
