This patch set provides functionality that will help to improve the locality of the async_schedule calls used to provide deferred initialization.
This patch set originally started out with me focused on just the one call to async_schedule_domain in the nvdimm tree that was being used to defer the device_add call however after doing some digging I realized the scope of this was much broader than I had originally planned. As such I went through and reworked the underlying infrastructure down to replacing the queue_work call itself with a function of my own and opted to try and provide a NUMA aware solution that would work for a broader audience.
RFC->v1: Dropped nvdimm patch to submit later It relies on code in libnvdimm development tree Simplified queue_work_near to just convert node into a CPU Split up drivers core and PM core patches v1->v2: Renamed queue_work_near to queue_work_node Added WARN_ON_ONCE if we use queue_work_node with per-cpu workqueue v2->v3: Added Acked-by for queue_work_node patch Continued rename from _near to _node to be consistent with queue_work_node Renamed async_schedule_near_domain to async_schedule_node_domain Renamed async_schedule_near to async_schedule_node Added kerneldoc for new async_schedule_XXX functions Updated patch description for patch 4 to include data on potential gains v3->v4 Added patch to consolidate use of need_parent_lock Make asynchronous driver probing explicit about use of drvdata Added Acked-by for PM core patch

Alexander Duyck (6): workqueue: Provide queue_work_node to queue work near a given NUMA node async: Add support for queueing on specific NUMA node device core: Consolidate locking and unlocking of parent and device driver core: Probe devices asynchronously instead of the driver driver core: Attach devices on CPU local to device node PM core: Use new async_schedule_dev command
