This changes _PAGE_PTE for 64-bit Book 3S processors from 0x1 to 0x4000_0000_0000_0000, because that bit is used as the L (leaf) bit by PowerISA v3.0 CPUs in radix mode. The "leaf" bit indicates that the PTE points to a page directly rather than another radix level, which is what the _PAGE_PTE bit means.
