This patch use the previously constructed domain numa-layout info to setup the domain memory. The domain vcpus are pinned according to allocation strategy in the following way : - CONFINE : all vcpus are pinned to the node cpus - STRIPE : all vcpus are pinned to the logical-or of the subset of node cpus - SPLIT : vcpus are pinned to the node from which the vnode is allocated Also, in case of SPLIT, the domain is made aware of the virtual NUMA enlightenment through a flag in xen_start_info (SIF_NUMA_DOMAIN). -dulloor Signed-off-by: Dulloor Rao <dulloor@xxxxxxxxxx>
