Merge branch 'sched-core-for-linus' of git://git./linux/kernel/git/tip/linux-2.6-tip

* 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (37 commits)
  sched: Fix SD_POWERSAVING_BALANCE|SD_PREFER_LOCAL vs SD_WAKE_AFFINE
  sched: Stop buddies from hogging the system
  sched: Add new wakeup preemption mode: WAKEUP_RUNNING
  sched: Fix TASK_WAKING & loadaverage breakage
  sched: Disable wakeup balancing
  sched: Rename flags to wake_flags
  sched: Clean up the load_idx selection in select_task_rq_fair
  sched: Optimize cgroup vs wakeup a bit
  sched: x86: Name old_perf in a unique way
  sched: Implement a gentler fair-sleepers feature
  sched: Add SD_PREFER_LOCAL
  sched: Add a few SYNC hint knobs to play with
  sched: Fix sync wakeups again
  sched: Add WF_FORK
  sched: Rename sync arguments
  sched: Rename select_task_rq() argument
  sched: Feature to disable APERF/MPERF cpu_power
  x86: sched: Provide arch implementations using aperf/mperf
  x86: Add generic aperf/mperf code
  x86: Move APERF/MPERF into a X86_FEATURE
  ...

Fix up trivial conflict in arch/x86/include/asm/processor.h due to
nearby addition of amd_get_nb_id() declaration from the EDAC merge.
