commit a57c27c7ad85c420b7de44c6ee56692d51709dda upstream.
The newly added function has two definitions but no prototypes:
drivers/base/cpu.c:605:16: error: no previous prototype for 'cpu_show_gds' [-Werror=missing-prototypes]
Add a declaration next to the other ones for this file to avoid the warning.
