Well, I was going over my config myself after you asked for me to post
it, and I thought to do the same thing. Except, disabling sched_debug
caused the same error as before:
In file included from kernel/sched.c:794:
kernel/sched_fair.c: In function 'task_new_fair':
kernel/sched_fair.c:857: error: 'sysctl_sched_child_runs_first'
undeclared (first use in this function)
kernel/sched_fair.c:857: error: (Each undeclared identifier is
reported only once
kernel/sched_fair.c:857: error: for each function it appears in.)
make[1]: *** [kernel/sched.o] Error 1
make: *** [kernel] Error 2

It only happens with sched_debug=y. I take it back, it wasn't my fault :)

As for everything else, I'd be happy to.
