Hmm, usually cvs update does a pretty good job merging changes. 
Certainly works for me ( with occasional conflict solving of course )

Fair enough.

Really? 4.0 was rebranched pretty recently, it can't be that far from 
HEAD-before-newlock2. I'd almost bet the OMAP stuff hasn't been touched 
since.

Fair enough. Did anyone do any measurements with the new threading code 
on ARM? I didn't get around to play with it on Shark yet but there are 
some platforms that actually got a noticeable speed boost from the new 
threading code ( namely macppc ).

Seriously - did you even look at the 4.0 branch? Or am I missing 
something here?
