ENABLE_KSM broken on stack.sh

[cminyard]

In stack.sh, you have

if [[ "ENABLE_KSM" == "True" ]] ; then
    if [[ -f /sys/kernel/mm/ksm/run ]] ; then
        sudo sh -c "echo 1 > /sys/kernel/mm/ksm/run"
    fi
fi

ENABLE_KSM needs a $ in front of it to work. Also, I think the == needs to be = to be consistent with the rest of the file.

Change-ID I4c5addfd3e83b6516023b36cbaabd5169f0d5ceb added this code.

    Change ENABLE_KSM to $ENABLE_KSM

    * Since ENABLE_KSM param will be used in local.conf file
      and it's value is received in a variable and while compairing,
      the variable needs to be compared. So we need to change the
      same.
