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.

Simple merge between master and 2.6.34 with conflicts resolved.
This commit does not compile, the following main problems are still
unresolved:
- spinlock -> raw_spinlock API changes
- kfifo API changes
- sched_class API changes

Port 2008.3 Core LITMUS^RT infrastructure to Linux 2.6.32
litmus_sched_class implements 4 new methods:
- prio_changed:
void
- switched_to:
void
- get_rr_interval:
return infinity (i.e., 0)
- select_task_rq:
return current cpu
