4-level paging supports translating 48-bit linear addresses to 52-bit
physical addresses. Since linear addresses are sign-extended,
the linear-address space of 4-level paging is: [0, 2^47-1] and
[0xffff8000_00000000, 0xffffffff_ffffffff]. So only [0, 2^47-1]
linear-address range maps to the identical physical-address range
when 5-Level paging is disabled.
