They were based on Andi's 4-level-pagetable work. Then we merged Nick's
4-level-pagetable work instead, so
numa-policies-for-file-mappings-mpol_mf_move.patch broke horridly and I
dropped it. Steve said he'd redo the patch based on the new pagetable code
and would work with SGI on getting it benchmarked, but that obviously
didn't happen.
I was a bit concerned about the expansion in sizeof(address_space), but we
ended up agreeing that it's numa-only and NUMA machines tend to have lots
of memory anyway. That being said, it would still be better to have a
pointer to a refcounted shared_policy in the address_space if poss, rather
than aggregating the whole thing.
