Pretty nice, and once again I congratulate you for not having to
virtualize x86.
I don't know how close you feel you are to merging, but from my point of
view things are looking good. We'll need to coordinate trees and acks
since this is touching more than just arch/arm/kvm.

Suggest eliminating the arm_ prefixes.
