Implement multi-level page tables.
Define L1_MAP_ADDR_SPACE_BITS to be either the virtual address size (in user mode) or physical address size (in system mode), and use that to size l1_map. This rewrites page_find_alloc, page_flush_tb, and walk_memory_regions. Use TARGET_PHYS_ADDR_SPACE_BITS for the physical memory map based off of l1_phys_map. This rewrites page_phys_find_alloc and phys_page_for_each. Signed-off-by: Richard Henderson <rth@twiddle.net>
