I have applied this to kvmarm/queue, fixing up a few trivial conflicts,
and I have changed the kvm_info message.

If you could test the integrated branch with GICv3 on a 32-bit platform,
that would be great.

I'll give people a few days to give their acks to the non-KVM part of
the series and will then put it in next.

Thanks for the work,
