Merge 'Linux v3.0' into Litmus
Some notes: * Litmus^RT scheduling class is the topmost scheduling class (above stop_sched_class). * scheduler_ipi() function (e.g., in smp_reschedule_interrupt()) may increase IPI latencies. * Added path into schedule() to quickly re-evaluate scheduling decision without becoming preemptive again. This used to be a standard path before the removal of BKL.
