Currently, we map DRAM as EFI_MEMORY_WB, and the remainder of the entire virtual address space is mapped with EFI_MEMORY_UC attributes, regardless of whether any devices actually reside there. Now that we are relaxing the address space limit to more than 40 bits, mapping all that address space actually takes up more space in page tables than we have so far made available as temporary RAM. So let's get rid of the mapping rather than increasing the available RAM, given that the mapping is not particularly useful anyway.
