The following series implements support for the architected generic
timers for KVM/ARM.

This patch series can also be pulled from:
    git://github.com/virtualopensystems/linux-kvm-arm.git
            branch: kvm-arm-v16-vgic-timers

Changes since v5:
 - Renamed sync_{to,from} to {flush,sync}_hwstate
 - Removed ISB's in world-switch code
 - Avoid add/sub on vcpu pointer in world-switch

Changes since v1-v4:
 - Get virtual IRQ number from DT
 - Simplify access to cntvoff and cntv_cval
 - Remove extraneous bit clearing
 - Abstract timer arming/disarming to improve code readability
 - Context switch CNTKCTL across world-switches
 - Add CPU hotplug notifier
