Hi Arun

These are useful suggestions and we will need a solution that covers all
possible scenarios for the page table walker, I have just begun looking
at the Ia64 code and so my responses may be slow until I get my head 
around it. One question I do have is that if we are initialising vhpt
in do_boot_cpu() are we only talking about SMP machines here, what 
about UNI processor machines?
