All architectures have been converted to use MEMBLOCK + NO_BOOTMEM. The
bootmem allocator implementation can be removed.

-/**
- * DOC: bootmem overview
- *
- * Bootmem is a boot-time physical memory allocator and configurator.
- *
- * It is used early in the boot process before the page allocator is
- * set up.
- *
- * Bootmem is based on the most basic of allocators, a First Fit
- * allocator which uses a bitmap to represent memory. If a bit is 1,
- * the page is allocated and 0 if unallocated. To satisfy allocations
- * of sizes smaller than a page, the allocator records the Page Frame
- * Number (PFN) of the last allocation and the offset the allocation
- * ended at. Subsequent small allocations are merged together and
- * stored on the same page.
- *
- * The information used by the bootmem allocator is represented by
- * :c:type:`struct bootmem_data`. An array to hold up to %MAX_NUMNODES
- * such structures is statically allocated and then it is discarded
- * when the system initialization completes. Each entry in this array
- * corresponds to a node with memory. For UMA systems only entry 0 is
- * used.
- *
- * The bootmem allocator is initialized during early architecture
- * specific setup. Each architecture is required to supply a
- * :c:func:`setup_arch` function which, among other tasks, is
- * responsible for acquiring the necessary parameters to initialise
- * the boot memory allocator. These parameters define limits of usable
- * physical memory:
- *
- * * @min_low_pfn - the lowest PFN that is available in the system
- * * @max_low_pfn - the highest PFN that may be addressed by low
- * memory (%ZONE_NORMAL)
- * * @max_pfn - the last PFN available to the system.
- *
- * After those limits are determined, the :c:func:`init_bootmem` or
- * :c:func:`init_bootmem_node` function should be called to initialize
- * the bootmem allocator. The UMA case should use the `init_bootmem`
- * function. It will initialize ``contig_page_data`` structure that
- * represents the only memory node in the system. In the NUMA case the
- * `init_bootmem_node` function should be called to initialize the
- * bootmem allocator for each node.
- *
- * Once the allocator is set up, it is possible to use either single
- * node or NUMA variant of the allocation APIs.
