Some compile errors on the (somewhat bizarre) CONFIG_SMP=3Dn,
CONFIG_NUMA=3Dy case:

> --- a/kernel/sched/core.c
> +++ b/kernel/sched/core.c
> +
> + =A0 =A0 =A0 select_task_node(p, p->mm, SD_BALANCE_FORK);
kernel/sched/core.c: In function =91sched_fork=92:
kernel/sched/core.c:1802: error: =91SD_BALANCE_FORK=92 undeclared (first
use in this function)

Also (from an earlier patch?)

In file included from kernel/sched/core.c:84:
kernel/sched/sched.h: In function =91offnode_tasks=92:
kernel/sched/sched.h:477: error: =91struct rq=92 has no member named =91off=
node_tasks=92
