You know, i rethought. Actually, the question concerns only "virt" machine,
because for other real machines the CPU should be the same as on real HW, and
this is no quest

And what is the default in x86_64 ? I believe it's 64-bit CPU, and not i686,
isn't it ?
I agree that -cpu

Yes. qemu-system-aarch64 -cpu cortex-a15 gets you

But 64-bit A15 is nonsense, because it's 32-bit CPU, isn't it?

This small patch fixes a long-standing bug: A15 model is used by default
also on ARM64 target. As a result, attempt to run the VM without explicit
-cpu specification does not do anything good.
