Hi Ingo,
  I have rebased the series against tip/cpus4096 as of today.  I
built/boot this kernel for both SMP/UP on a 4-way x86_64 box, and they
look sane.  Let me know if they still look broken to you.

The following changes since commit 6092848a2a23b660150a38bc06f59d75838d70c8:
  Sergio Luis (1):
        x86: mark get_cpu_leaves() with __cpuinit annotation

are available in the git repository at:

sched/latest

Gregory Haskins (11):
      sched: cleanup inc/dec_rt_tasks
      sched: track the next-highest priority on each runqueue
      sched: use highest_prio.curr for pull threshold
      sched: use highest_prio.next to optimize pull operations
      sched: only try to push a task on wakeup if it is migratable
      sched: pull only one task during NEWIDLE balancing to limit
critical section
      sched: make double-lock-balance fair
      sched: add sched_class->needs_post_schedule() member
      plist: fix PLIST_NODE_INIT to work with debug enabled
      sched: create "pushable_tasks" list to limit pushing to one attempt
      RT: fix push_rt_task() to handle dequeue_pushable properly
