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
