v3 contains the following changes since v2:
This is still based on 23-rt1 + Steve's last public patch (I think Steve has a newer version available, but we have not rebased yet).
1) No longer includes the per-cpu-rtoverload patch, since Steve has already ACKed it 2) Dropped the affinity patch because it was buggy. Will revisit later 3) Dropped the pull-patch, since it was RFC only anyway. Will revisit later 4) Addressed review comments/feedback (added patch descriptions across the board, moved semi-colon in while loop, removed superfluous smp_processor_id() etc. 5) Got rid of the second TASK_PREEMPTS_CURR() check, since my anaylsys determined it was not needed.
With this patch series applied, my RT test now passes and we get an average of 23us wake-up latency under load. You can find the test here:

Note: Do not use the "affinity" option, as the validator has a bug related to it and may yield a false negative.
Regards, -Greg
