Linux Kernel Markers

Hi,

This updated version of the Linux Kernel Markers mostly adds a unique 16 bits
per marker ID and a per-probe marker group.

Christoph, I think the only concern that I do not plan to address immediately is
to provide a complet in-kernel user of the markers (blktrace patch does not
actually use the markers full potential). I have external patches that provides
that, but I don't want to send too much patches at once. Between providing a
complete marker/tracer stack and sending small incremental patches, I think the
latter is the choice the better suited. This is however an uneasy problem, which
looks very much like the chicken and egg problem. :)

If you have concerns with what I recently added to the markers, or if you still
strongly feel that I must also send the following patches right away, please let
me know.

Mathieu
