[PATCH 0/3] Early node associativity

[Srikar Dronamraju <srikar@linux.vnet.ibm.com>]

Abdul reported  a warning on a shared lpar.
"WARNING: workqueue cpumask: online intersect > possible intersect".
This is because per node workqueue possible mask is set very early in the
boot process even before the system was querying the home node
associativity. However per node workqueue online cpumask gets updated
dynamically. Hence there is a chance when per node workqueue online cpumask
is a superset of per node workqueue possible mask.

The below patches try to fix this problem.
