My kernel parm has cmma=on. Is there a way to display that it is actually active?

I'm sure cmm.ko is what has been called CMM-1. CMMA has been called CMM-2. From a post in 2009 by Christian Borntraeger makes me assume CMM-2 lite is still there: You also have to distinguish CMM-2 full (SLES10) and CMM-2 lite. We were not able to bring the full CMM-2 version upstream, but the lite version is upstream. So the work in z/VM and hardware is not wasted. CMM-2 lite also uses CMMA, so every recent kernel can use the CMMA facility. CMM2-lite uses only two page states (used vs. unused) while the CMM2 in SLES10 uses 4 page states.
