PTE entries

[Siva Prasad]

Thanks Ben.

I managed to fix this. I am working on how best we can rewrite the self
modifying code we have for create_hpte routine. I would prefer to read
from SDR1, than to hardcode (or self modify the code) the way it is done
now.

Feel free to let me know what you think.

Thanks
Siva
