  ARM: KVM: arch_timers: Wire the init code and config option
  ARM: KVM: arch_timers: Add timer world switch
  ARM: KVM: arch_timers: Add guest timer core support
  ARM: KVM: Add VGIC configuration option
  ARM: KVM: VGIC initialisation code
  ARM: KVM: VGIC control interface world switch
  ARM: KVM: VGIC interrupt injection
  ARM: KVM: vgic: retire queued, disabled interrupts
  ARM: KVM: VGIC virtual CPU interface management
  ARM: KVM: VGIC distributor handling
  ARM: KVM: VGIC accept vcpu and dist base addresses from user space
  ARM: KVM: Initial VGIC infrastructure code
  ARM: KVM: Keep track of currently running vcpus
  KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR ioctl
  ARM: gic: add __ASSEMBLY__ guard to C definitions
  ARM: gic: define GICH offsets for VGIC support
  ARM: gic: add missing distributor defintions
