Currently x86 numa_meminfo is marked __initdata in the CONFIG_MEMORY_HOTPLUG=n case. In support of a new facility to allow drivers to map reserved memory to a 'target_node' (phys_to_target_node()), add support for removing the __initdata designation for those users. Both memory hotplug and phys_to_target_node() users select CONFIG_NUMA_KEEP_MEMINFO to tell the arch to maintain its physical address to NUMA mapping infrastructure post init.

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.
