Add the PAE flag to processor information

To add the PAE flag to the processor information stored in /proc/cpuinfo, run the following:

      cat /proc/cpuinfo | sed 's/flags\t*:/& pae/' > /tmp/cpuinfo_pae
      sudo mount -o bind /tmp/cpuinfo_pae /proc/cpuinfo
      sudo mount -o remount,ro,bind /proc/cpuinfo 

After you have ran those commands, run

 grep flags /proc/cpuinfo 

If the flag was correctly added, the command returns a line that starts with “flags :” and contains the flag “pae”.
