i think these markers are still in active use, so i'd not remove 
them before Ted's TRACE_EVENT() changes are included. We can/should 
do that in a single topic - in a work flow that suits Ted best.

We can do a -git based special-purpose topic branch in -tip, or we 
can do it in tip/tracing, or we can pull a (-git based) branch from 
Ted. Or we can delay it all to the v2.6.31 merge window. Ted's 
choice.
