Hi Dave, Sima,

One display fix for the merge window relating to DisplayPort LTTPR. It
fixes at least Dell UD22 dock when used on Intel N100 systems.

Hi Dave, Sima,

Two fixes for the merge window - turning off preemption on Gen8 since it
apparently just doesn't work reliably enough and a fix for potential NULL
pointer dereference when stolen memory probing failed.
