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.
