------------------------------------------------------
Subject: scheduler: NUMA aware placement of sched_group_allnodes
From: Christoph Lameter <clameter@xxxxxxx>
When the per cpu sched domains are build then they also need to be placed
on the node where the cpu resides otherwise we will have frequent off node
accesses which will slow down the system.
