out, bits [31:8], [6:3], [1:0] are under swapper control, so only bit[7] is

left for us to select. If we force bit[7]==0 when swapped out, we could use
|
||||
the combination bit[7,2]=2'b10 to indicate an empty PTE. Alternatively, if
|

we force bit[7]==1 when swapped out, we can use all zeroes to indicate
|

empty. This is convenient, because the page tables get cleared to zero
