1. Stability
2. performance
3. easier to read
4. more debug info


The 2nd goal is very hard to measure. It seems function alignment changes swamp
most any other improvements. I think that if the same measurement that I did were done
with a different compiler, you would see different patches increased/decreased
the BPS. But at least the overall trend on the patch set is positive. And
each individual patch has been tested. I would like someone to test on a machine
with 3 queues though.


If you have a more accurate way to measure performance, please let me know.
Also, if you know why freescale's bsp has so much better performance
that would be a very welcome patch.
