Merge tag 'kvm-arm-for-3.18-take-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm
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 ]
