Yep I'm aware of that and sorry - there's no easy way to "underline" 
stuff in a patch :-)

Depends on who you ask. I think it is still relevant for embedded 
platforms.? Especially when doing new CPU and/or ISA bringup - former we 
tend to do regularly at Synopsys it gives you a great "snapshot" of 
performance of 2 systems: old and new. And this is true starting from 
fork/shell latency to memory latency and bandwidth tests which are still 
pretty smart for something written so long ago.

Thx for merging the patches.
