workqueue: move function definitions within CONFIG_SMP block
In commit 7ee681b25284 ("workqueue: Convert to state machine callbacks"), three new function definitions were added: ‘workqueue_prepare_cpu’, ‘workqueue_online_cpu’ and ‘workqueue_offline_cpu’. Move these function definitions within a CONFIG_SMP block since they are not used outside of it. This will match function declarations in header <include/linux/workqueue.h>, and silence the following gcc warning (W=1): kernel/workqueue.c:4743:5: warning: no previous prototype for ‘workqueue_prepare_cpu’ [-Wmissing-prototypes] kernel/workqueue.c:4756:5: warning: no previous prototype for ‘workqueue_online_cpu’ [-Wmissing-prototypes] kernel/workqueue.c:4783:5: warning: no previous prototype for ‘workqueue_offline_cpu’ [-Wmissing-prototypes] Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org>
