Real-time preemption patches

• Linux kernel patches from Ingo Molnar http://people.redhat.com/~mingo/realtime-preempt/

• Available for any recent kernel version (> 2.6.12)

• When full preemption is enabled, add unprecedented responsiveness to the Linux kernel. Less latency, suitable for real real-time systems (less than 100 us!).

• Definitely worth trying on old systems to improve the user experience!
