sched/numa: Hide numa_wake_affine() from UP build
Stephen reported the following build warning in UP: kernel/sched/fair.c:2657:9: warning: 'struct sched_domain' declared inside parameter list ^ /home/sfr/next/next/kernel/sched/fair.c:2657:9: warning: its scope is only this definition or declaration, which is probably not what you want Hide the numa_wake_affine() inline stub on UP builds to get rid of it. Fixes: 3fed382b46ba ("sched/numa: Implement NUMA node level wake_affine()") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Rik van Riel <riel@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org>
