Subject: [PATCH -next] powerpc/spufs: Fix build warning when CONFIG_PROC_FS=n

arch/powerpc/platforms/cell/spufs/sched.c:1055:12: warning: ‘show_spu_loadavg’ defined but not used [-Wunused-function]
 static int show_spu_loadavg(struct seq_file *s, void *private)
            ^~~~~~~~~~~~~~~~

Mark this as __maybe_unused to fix this.
