Failure with macOS 15.2 on ARM64: Property 'host-arm-cpu.sme' not found

I ran a FreeBSD arm64 vm on a M4 Mac Mini using macOS 15.1.1. That worked fine.

After updating the OS to macOS 15.2 I get this error:

Unexpected error in object_property_find_err() at ../qom/object.c:1350: qemu-system-aarch64: Property 'host-arm-cpu.sme' not found
