The original change for above patch has a bit less checking for gen8. Not really
sure how good or bad that is. Generally thewhole bunch is not really well

It is a bit scary that this time the whole lot goes into the commonly used
driver. A very grudging ACK... and hoping you did test Utopic as thoroughly...
