Heiko, if you remove all these:

./time/tick-broadcast.c:#include <linux/irq.h>
./time/tick-oneshot.c:#include <linux/irq.h>
./time/tick-common.c:#include <linux/irq.h>
./hrtimer.c:#include <linux/irq.h>

from kernel/*, do things improve on s390? If yes then please send a
patch for it and i'll check whether there's any include file dependency
fallout on x86.
