I left this here to simplify merging with kvm-userspace.git.  I don't 
have any intention of enabling it though and it will disappear once we 
get the DMA API committed.

I didn't want anyone to think there are any plans to enable it as it 
enables code that does bad things (touching guest physical memory directly).
