23 DISCONTIGMEM is a more mature, better tested system,
107 # Architecture platforms which require a two level mem_section in SPARSEMEM
127 SPARSEMEM_VMEMMAP uses a virtually mapped memmap to optimise
153 boolean "Enable to assign a node which has only movable memory"
160 Allow a node to have only movable memory. Pages used by the kernel,
168 memory of a node as movable memory so that the whole node can be
175 Say Y here if you want to hotplug a whole node.
208 # use a virtual memmap. Disable extended page flags for 32 bit platforms
209 # that require the use of a sectionid in the page flags.
