Just an FYI, but with next-20150615 (and I think some previous days too IIRC),
In file included from include/linux/rcupdate.h:429:0,
from include/linux/srcu.h:33,
from include/linux/notifier.h:15,
from include/linux/memory_hotplug.h:6,
from include/linux/mmzone.h:797,
from include/linux/gfp.h:5,
from include/linux/kmod.h:22,
from include/linux/module.h:13,
from kernel/rcu/rcutorture.c:28:
include/linux/rcutiny.h: In function ‘rcu_barrier_sched’:
include/linux/rcutiny.h:55:20: internal compiler error: Segmentation fault
static inline void rcu_barrier_sched(void)
^
That's with a random configuration file setting

Agreed. Can you reproduce this with a preprocessed file ("make
kernel/rcu/rcutorture.i" first), and then provide that file in a bug
report to GCC?
