Currently arm64 allows a choice of FLATMEM, SPARSEMEM and SPARSEMEM_VMEMMAP. However, only the latter is tested regularly. FLATMEM does not seem to boot in certain configurations (guest under KVM with Qemu as a VMM). Since the reduction of the SECTION_SIZE_BITS to 27 (4K pages) or 29 (64K page), there's little argument against the memory wasted by the mem_map array with SPARSEMEM. Make SPARSEMEM_VMEMMAP the only available option, non-selectable, and remove the corresponding #ifdefs under arch/arm64/.
