keir & harper,

You know, currently alloc_domheap_pages try to alloc mem from the node where
current LP sit, which is not always right. E.g some hypercall issued from dom0's
LP allocate memory for other domains.

This patch intend to resolve this issue on NUMA system by locating node from 
the 
served domain.

A new interface alloc_domheap_pages_on_node is introduced instead of changing 
current implementation, which is invasive.

There are still many places left for the new interface, but we can change them 
in a incremental way if needed.


Appreciate your comments.
