yes, sorry, I shouldn't have been so grumpy about it.

After spending 45 minutes digging through the kernel source and other 
documentation it all makes sense now.  The existing manpage even does a 
mildly accurate job of explaining the situation.  It's just I have enough 
trouble keeping up with the large number of recent perf related patches 
without having to spend a lot of time decoding cryptic Changelogs.
