This is a release of Preempt Real-time for ARM . It includes everything
up to CONFIG_PREEMPT_RT , and all of the latency tracing except
interrupts off timing. The timing also excludes syscalls. This patch
includes only a port to OMAP boards. However, it should be straight
forward to get it working on other boards.

The biggest point of discussion relates to the interrupts in threads
implementation. It is largely identical to what is implemented in the
generic irq handling. However, ARM doesn't not implement generic irq
handling, and will not support it in the near future. I am not in
support of two different threaded interrupt implementations.

I recently made a proposal to separate the threaded interrupt handling
from the generic irq handling, but I'm open to other ideas.
