KVM/arm64 changes for 7.3, take #3

Hi Paolo,

As promised, the patches I was waiting on have baked and we have another batch of fixes for 7.3. Continuing with the trend, the VGIC is getting some additional attention, particularly on the handling of a vCPU's AP list.

Unless there's something truly horrible brewing in the next couple of weeks, I expect this to be the last fixes pull for 7.3 with Marc taking over the tree for 7.4.

Please pull.

Thanks,
Oliver
