Subject: sched/numa: Hide numa_wake_affine() from UP build

From: Thomas Gleixner <[email protected]>

commit ff801b716effd652f420204eddb36f6e4a716819 upstream.

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.
