At previous week I started to design a kernel patching framework and I have a little holiday. At this week I mostly finished the design, and started to implement the selfpatching framework. Next week I plan to finish the implementation of the framework, and after that migrate the SMAP stuff to use them. The current status can you found on my wiki site.
