[patch 3/4] intr_remap: Allocate intr-remapping table using numa locality info

[Suresh Siddha]

Allocate intr-remapping table using numa locality info. On platforms
having remapping hardware units span different nodes, this enables
optimized intr-remapping table entry access by remapping hardware.
