Subject[driver-core PATCH v4 0/6] Add NUMA aware async_schedule calls
This patch set provides functionality that will help to improve the
locality of the async_schedule calls used to provide deferred

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.

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
Renamed queue_work_near to queue_work_node
Added WARN_ON_ONCE if we use queue_work_node with per-cpu workqueue
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
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
