Cover letter [RFC 0/7] LTTng Kernel Instrumentation (Architecture Independent)

Hi,

I submit this instrumentation of the main kernel events using markers to the Linux community as an RFC. This is the instrumentation LTTng (Linux Trace Toolkit Next Generation, at http://ltt.polymtl.ca) uses.

In addition to this, I also have architecture dependent instrumentation for:
- traps
- system call entry/exit
- kernel thread creation
- IPC call
which I plan to submit a bit later, once these architecture independent core instrumentation patches will have been discussed.

The goal here is be be able to tell "what the kernel is doing" so we can :
- get execution traces from bug reporters easily.
- help userspace developers to understand the interactions of their programs with other processes and with the kernel.

Mathieu
