Hi Eric,

arch/arm64/kvm/../../../virt/kvm/arm/vgic/vgic-its.c:1766:33: error: 'its' undeclared (first use in this function)

      return vgic_its_table_restore(its);

I think this is due to the fact the series is applied on KVM: arm/arm64:
Emulate the EL1 phys timer registers (kvmarm-for-4.11).

Please apply it to (kvmarm/queue, kvmarm/next, kvm_next) KVM: arm/arm64:
vgic: Improve sync_hwstate performance  (255905e)
I also checked it compiles on 4.11-rc4.

Please let me know if I got something wrong.

Thanks

Eric
