+Subject: [PATCH] sparc64: Fix BIOS Boot Partition support
+
+Currently, gpt_offset is uninitialised when using a BIOS Boot Partition
+but is used unconditionally inside save_blocklists. Instead, ensure it
+is always initialised to 0 (note that there is already separate code to
+do the equivalent adjustment after we call save_blocklists on this code
+path).
+
+This patch has been tested on a T5-2 LDOM.
