“Intel 64 architecture defines a 64-bit linear address. Implementations can support less. The first implementation of
IA-32 processors with Intel 64 architecture supports a 48-bit linear address. This means a canonical address must
have bits 63 through 48 set to zeros or ones (depending on whether bit 47 is a zero or one).”
