3.5.7.18 -stable review patch. If anyone has any objections, please let me know. ------------------ From: bob picco <bpicco@xxxxxxxxxx> commit 771a37ff4d80b80db3b0df3e7696f14b298c67b7 upstream. The Machine Description (MD) property "address-congruence-offset" is optional. According to the MD specification the value is assumed 0UL when not present. This caused early boot failure on T5.
