Subject: [workqueue/driver-core PATCH 0/5] 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
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.

v2: 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.

Alexander Duyck (5):
      workqueue: Provide queue_work_near to queue work near a given NUMA node
      async: Add support for queueing on specific NUMA node
      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
