Hi Max,
I have added the SMP patch-set to the for_next tree (for the time
being). Let me know if you wanted it in for this release or if you think
it's not ready for prime time. Note that I skipped the variant
configuration as it is a lot of code and it is more of a 'test'
configuration.
Thanks,
-Chris
