Here as well this is the wrong approach. If you want to save memory,
you should make ksmd quit when run=0 and start only when setting
ksm/run=1. And move the daemon hashes and slabs initializations to the
ksmd daemon start. Not registering in sysfs and crippling down the
feature despite you loaded the proper .text into memory isn't good.
