I havent tested but i tested appling rt8 to 3.0 and then git diffstat.
Kind of a manual bisecting. Since you still seem to be currently looking at 
this: 
The current remaining offenders on the list from 3.0-rt7 are:
 git diff --stat rt8-test
 kernel/ksysfs.c       |   12 ------
 kernel/lockdep.c      |    5 ++-
 kernel/sched_cpupri.c |   28 ++-------------
 localversion-rt       |    2 +-
 mm/memory.c           |    2 -
 mm/slab.c             |   92 +++++++++++-------------------------------------
