These two patches were sent separately earlier. There are a couple of

was left behind.

Are you sure this actually implements the CPUID 4 leaf? I bet it simply submits multiple KVM_SET_CPUID ioctls, from which the kernel module picks the last one (0), not exposing _any_ cache information to the guest.

For exactly this purpose KVM_SET_CPUID2 was introduced quite a while ago, enabling support for all CPUID leaf flavors on the kernel side. Merely the userspace call is missing.

Nevertheless - thanks for taking onto this. Cpuid4 enabling is one of the (pretty low-prio) items on my TODO list for Mac OS X guest support.
