I forgot to account for tracking page table physical addresses, so this is a bit of an overhaul. Major changes: - Refactor bootstrap code into more functions and: - Only allocate 32 pages of scratch space - Remap remaining space into top 256GiB, the "page table space" - Use the page table space to directly offset-map page table pages from their physical addresses, to avoid tracking overhead. - Refactor page_block list functions into static functions to better handle null/empty lists
