Subject: [PATCH] sparc64 address-congruence property
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.
