That's the one with the "lazy realize" hack, right? I imagine
what's happening is that we realize the GIC, and the code in
this patch assumes that all the CPUs are already realized at
that point. When we try to get the register value for a
not-yet-realized CPU the kernel complains.

(I strongly agree with Igor's review remarks here
https://lore.kernel.org/qemu-devel/20251006160027.20067fe4@fedora/
that lazy realizing of CPU objects is a bad idea.)
