Update the pseries memory hotplug code to use the newly added dynamic reconfiguration LMB array. Doing this is required for the upcoming support of version 2 of the dynamic reconfiguration device tree property. In addition, making this change cleans up the code that parses the LMB information as we no longer need to worry about device tree format. This allows us to discard one of the first steps on memory hotplug where we make a working copy of the device tree property and convert the entire property to cpu format. Instead we just use the LMB array directly while holding the memory hotplug lock. This patch also moves the updating of the device tree property to powerpc/mm/drmem.c. This allows to the hotplug code to work without needing to know the device tree format and provides a single routine for updating the device tree property. This new routine will handle determination of the proper device tree format and generate a properly formatted device tree property.

README
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.
