  From: Arnd Bergmann <arnd@arndb.de>

The schedule_user() function is used on powerpc and sparc architectures, but
only ever called from assembler, so it has no prototype, causing a harmless W=1
warning:

kernel/sched/core.c:6730:35: error: no previous prototype for 'schedule_user' [-Werror=missing-prototypes]

Add a prototype in sched/sched.h to shut up the warning.
