* git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched: sched: proper prototype for kernel/sched.c:migration_init() sched: avoid large irq-latencies in smp-balancing sched: fix copy_namespace() <-> sched_fork() dependency in do_fork sched: clean up the wakeup preempt check, #2 sched: clean up the wakeup preempt check sched: wakeup preemption fix sched: remove PREEMPT_RESTRICT sched: turn off PREEMPT_RESTRICT KVM: fix !SMP build error x86: make nmi_cpu_busy() always defined x86: make ipi_handler() always defined sched: cleanup, use NSEC_PER_MSEC and NSEC_PER_SEC sched: reintroduce SMP tunings again sched: restore deterministic CPU accounting on powerpc sched: fix delay accounting regression sched: reintroduce the sched_min_granularity tunable sched: documentation: place_entity() comments sched: fix vslice
