Note that ARMv7MState also has a property of the same name but this patch doesn't change it because that class isn't a subclass of CPUState so it wouldn't be a trivial change. This change should not cause any change in behavior.

charset="utf-8" PowerPC sPAPR CPUs start in the halted state, and spapr_reset_vcpu() attempts to implement this by setting CPUState::halted to 1. But that's too late for the case of hotplugged CPUs in a machine configure with 2 or more threads per core. By then, other parts of QEMU have already caused the vCPU to run in an unitialized state a couple of times. For example, ppc_cpu_reset() calls ppc_tlb_invalidate_all(), which ends up calling async_run_on_cpu(). This kicks the new vCPU while it has CPUState::halted =3D 0, causing QEMU to iss= ue a KVM_RUN ioctl on the new vCPU before the guest is able to make the start-cpu RTAS call to initialize its register state. This problem doesn't seem to cause visible issues for regular guests, but on a secure guest running under the Ultravisor it does. The Ultravisor relies on being able to snoop on the start-cpu RTAS call to map vCPUs to guests, and this issue causes it to see a stray vCPU that doesn't belong to any guest. Fix by setting the start-powered-off CPUState property in spapr_create_vcpu(), which makes cpu_common_reset() initialize CPUState::halted to 1 at an earlier moment.

This makes secondary_cpu_reset() unnecessary, so remove it. Also remove setting of cs->halted from cpu_devinit(), which seems out of place when compared to similar code in other architectures (e.g., ppce500_init() in hw/ppc/e500.c). Finally, change creation of CPU object from cpu_create() to object_new() and qdev_realize_and_unref() because cpu_create() realizes the CPU and it's not possible to set a property after the object is realized.
