The Power Hypervisor has introduced a new device tree format for the property describing the dynamic reconfiguration LMBs for a system, ibm,dynamic-memory-v2. This new format condenses the size of the property, especially on large memory systems, by reporting sets of LMBs that have the same properties (flags and associativity array index). This patch updates the powerpc/mm/drmem.c code to provide routines that can parse the new device tree format during the walk_drmem_lmb* routines used during boot, the creation of the LMB array, and updating the device tree to create a new property in the proper format for ibm,dynamic-memory-v2.

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.
