Ok I got bisection working finally, now I'm at d5be23e2 I have something like 80 revisions left and
I'm stuck with this:

In file included from kernel/sched.c:1861:
kernel/sched_rt.c: In function 'check_preempt_curr_rt':
kernel/sched_rt.c:653: error: implicit declaration of function 'cpupri_find'
kernel/sched_rt.c:653: error: 'struct root_domain' has no member named 'cpupri'
make[1]: *** [kernel/sched.o] Error 1
make: *** [kernel] Error 2

This error is caused by commit 677ceea32cf1d8ba9a4870bc58079cd7e7f77558
("sched: prioritize non-migratable tasks over migratable ones") in the
sched tree (sched/for-akpm).  This commit is either just wrong, is was
misrebased, or is just badly out of order.  It introduces a use of
cpupri_find, but the function is not defined until commit
ea9b3c95b7c666d4658a139b88587269e5baa647 ("sched: use a 2-d bitmap for
searching lowest-pri CPU") about 146 commits later ...
