grrr... i was hoping no one would ask that question. I am not aware of 
any in tree. We use it locally in custom tracepoints in the networking 
stack (from what I can tell netdev will not take -- LTTng tried many 
years ago) and in a couple of klms.

The attached patch is what I used to test (plus our local versions). It 
is derived from a patch on the 3.4 kernel which allows us to trace 
address changes.
