Re: [Qemu-devel] should KVM or userspace be the one which decides what MIPIDR/affinity values to assign to vcpus?

I agree it's not very likely anybody cares about the specific cluster
topology. However if we don't want to support arbitrary topologies
then QEMU is going to end up in the business of editing the user
supplied device tree blob to make its cpu definitions match up with
whatever the kernel provides, which could be pretty tedious.
