very nice stuff!

i've created a new topic branch for this: 

   tip/tracing/hw-branch-tracing

and applied your patches there. (applied the earlier x86 patches in 
their appropriate x86 topic branches)

Integrated the end result into tip/master and have started testing it.

I've got a few more review comments as well - will post them as a 
reply to the respective patches.
