check the tree :-) It has these commits too:

Markers use imv jump
Linux Kernel Markers - Use Immediate Values
Markers - define non optimized marker
Markers - remove extra format argument

LTTng instrumentation net
LTTng instrumentation mm
LTTng instrumentation kernel
LTTng instrumentation ipc
LTTng instrumentation fs

[ the latter ones are only there for testing - Mathieu is working on a
different approach for syscall instrumentation. ]

Enjoy,

Ingo
