Ok, I just noticed this (we must've missed it during review) but why is
this read-only? If it has to be read-only, why do we have a node for
this in sysfs instead of simply issuing the printk statements below and
people who are interested in this, can grep dmesg?

This was added so that user-space tools could find out if we're using thresholds for CMCI.
