I don't feel like I'm actually qualified to ack the mm and binfmt
changes, but everything *looks* correct to me, and you've fixed the flag
numbering such that it can go in mman-common.h as I suggested.

So if the name was MAP_FIXED_NOREPLACE I would also be happy with it.

I can resubmit with the name changed if that's what it takes.
