In each case, the size of the incoming address is widened by 2~bits (to 34, 41, -or 50 bits). +50, or 59 bits). To accommodate the 2~extra bits, the root page table (only) is expanded by a factor of four to be 16~KiB instead of the usual 4~KiB. Matching its larger size, the root page table also must be aligned to a 16~KiB |
