This code change to have various TTU_* be bitflag instead of value. I am
not sure what was the win in that, would need to dig up that patch that
did that. But in all the case i preserve that change here hence starting
at 9.

Unless there is a deeper purpose that I am overlooking, I think it would
be better to leave the _MLOCK, _ACCESS, and _HWPOISON at their original

instead of bit 8...
