I hope you enjoyed the holidays. Thanks for applying the patches.

I've been busy working on the event handling code. I saw a lot of
opportunity for cleanups and improvements and also had some internal
feedback that event handling performance was slow with many signal
events. I hope to have a patch series ready for review by the end of
this week. After that I want to get back to SDMA support.
