Hi,

This patchset include patches for supporting 64TB with ppc64. I haven't booted
this on hardware with 64TB memory yet. But they boot fine on real hardware with
less memory. Changes extend VSID bits to 38 bits for a 256MB segment
and 26 bits for 1TB segments. 

Changes from V1:
* Drop the usage of structure (struct virt_addr) to carry virtual address.
  We now represent virtual address via vpn which is virtual address shifted 
  right 12 bits.

Thanks,
-aneesh
