I'm maintaining the KVM/ARM implementation, which was merged during
the 3.9 merge window.
I'd like for you to pull changes from my kvm-arm-next branch at
git://github.com/columbia/linux-kvm-arm.git into linux-next.
The merge procedure for this tree is typically through the kvm tree,
Unless I'm mistaken, the size field was encoded 4 bits off and a wrong
