This turns off some memory savings that linux-kvm carried. Those savings, however, are minimal, and do not justify the runtime penalty and did not account to significant boot time savings. This also lead to a limit in PIDs on the system that caused degraged boot when systemd-sysctl tried to change the default maximum PID.
