movable_node_is_enabled is defined in memblock proper while it is initialized from the memory hotplug proper. This is quite messy and it makes a dependency between the two so move movable_node along with the helper functions to memory_hotplug. To make it more entertaining the kernel parameter is ignored unless CONFIG_HAVE_MEMBLOCK_NODE_MAP=y because we do not have the node information for each memblock otherwise. So let's warn when the option is disabled.

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.
