Pull second batch of changes for KVM/{arm,arm64} from Marc Zyngier:
 "The most obvious thing is the sizeable MMU changes to support 48bit
  VAs on arm64.

  Summary:

   - support for 48bit IPA and VA (EL2)
   - a number of fixes for devices mapped into guests
   - yet another VGIC fix for BE
   - a fix for CPU hotplug
   - a few compile fixes (disabled VGIC, strict mm checks)"

[ I'm pulling directly from Marc at the request of Paolo Bonzini, whose
  backpack was stolen at Düsseldorf airport and will do new keys and
  rebuild his web of trust.    - Linus ]
