Ah, with "the last reserved bit" I didn't mean AutoNUMA is using
it. It just means there is nothing left if somebody in the future
needs it. AutoNUMA happened to need it initially, but I figured how I
was better off not using it. Initially I had to make AUTONUMA=y
mutually exclusive with XEN=y but it's not the case anymore. So at
this point the patch is only a cleanup, I could drop it too but I
thought it was cleaner to keep it.
