Yea that's why I've copied linux-mm on the first two patches. 
Reallocating the page tables works sane and is simple, but whether or 
not we may export dup_mm is the real question.

Glad to hear that you like the patchset. It would be cool if you could 
pull from Linus soon, because we do need a patch not yet in the 
kvm.git that the series is based upon. After that, we'll integrate the 
review feedback, rebase to latest git, and resubmit the series.

I'll see what I can do to get you access to a box. We'll also be 
following kvm.git closely during the kernel release cycles and report 
regressions or submit patches to clean them up.
