This patch convert different functions to take virtual page number
instead of virtual address. Virtual page number is virtual address
shifted right by VPN_SHIFT (12) bits. This enable us to have an
address range of upto 76 bits.
Mostly looks good. I don't think it's necessary to add the
BUILD_BUG_ON and BUG_ON conditions. I would think a comment next to
the definition saying that VPN_SHIFT can be at most 12 would be
sufficient.
Updated.
Thanks
