Good idea, I'll spin up a patch to do this. Hrm, need to add a case to
the slice functions for ia64 after all.
As I understand it, IA64 has one large slice that can contain huge pages
from 2^63 to the end of the address space? Is that accurate?
So start will always be 2^63 and end will always be 2^64-1?
Thanks,
Nish
