Subject: [ 11/45] sparc64 address-congruence property

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: bob picco <bpicco@...oft.net>

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.
