Linus, please pull the latest scheduler git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched-devel.git for-linus
(the topology.h change is a NOP for upstream, to make it easier for s390
to work on their topology changes.)
Thanks,
Ingo
------------------>
Heiko Carstens (2):
sched: add exported arch_reinit_sched_domains() to header file.
sched: add arch_update_cpu_topology hook.
Peter Zijlstra (1):
sched: cleanup old and rarely used 'debug' features.
Roel Kluin (1):
sched: remove double unlikely from schedule()
