Planned SMP Improvements

I added three tickets that will lead to a major improvement of the SMP
capabilities of RTEMS in case we are able to implement them:
New watchdog handler implementation
Eliminate the Giant lock
Implement the O(m) Independence-Preserving Protocol (OMIP)
It takes several weeks of work to implement them and it will lead to
major changes in core operating system components. Besides the increased
complexity in the locking protocols I don't expect negative impact for
the uni-processor configurations. Please review these tickets. I would
be happy about feedback.
Maybe we can implement
Improve the SMP scheduler with arbitrary processor affinity support
as part of this years GSoC.
Once this is done we have a state-of-the-art real-time operating system
for SMP systems in the single-process/multi-thread environment from my
point of view.
