Extend the existing PRRN infrastructure to perform the actual affinity updating for cpus and memory in addition to the device tree updating. For cpus, dynamic affinity updating already appears to exist in the kernel in the form of arch_update_cpu_topology(). For memory, we must place a READD operation on the hotplug queue for any phandle included in the PRRN event that is determined to be an LMB.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
