+From dbb988cf34a62e69c8863f212be212c6841004ba Mon Sep 17 00:00:00 2001
+From: David S. Miller <davem@davemloft.net>
+Date: Sat, 26 Feb 2011 23:40:02 -0800
+Subject: [PATCH] sparc64: Fix build errors with gcc-4.6.0
+
+Most of the warnings emitted (we fail arch/sparc file
+builds with -Werror) were legitimate but harmless, however
+one case (n2_pcr_write) was a genuine bug.
+
+Based almost entirely upon a patch by Sam Ravnborg.
+
+Reported-by: Dennis Gilmore <dennis@ausil.us>
