could you please send a delta patch against tip/x86/uv - or just 
tip/master? You can pick it all up from:

  http://people.redhat.com/mingo/tip.git/README

it's better to have all these delta patches in a consecutive way, as 
everything up to your previous version of v5 has already been tested 
pretty thoroughly on non-UV hardware and is ready to be pushed into 
linux-next.

I'd suggest you name the new delta patch as v6, as there's a "v5" patch 
applied already.

( Also, you might want to check whether tip/master properly works on
  your simulator - to double-check whether the integration of x86/uv 
  changes with other x86 changes went fine. )

Thanks,

	Ingo
