Force the device registration for nvdimm devices to be closer to the actual device. This is achieved by using either the NUMA node ID of the region, or of the parent. By doing this we can have everything above the region based on the region, and everything below the region based on the nvdimm bus. By guaranteeing NUMA locality I see an improvement of as high as 25% for per-node init of a system with 12TB of persistent memory.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
