I fixed a double typo in r3053.

Is HWLOC_MEMBIND_MIXED defined somewhere?

I am not sure about "on next touch ... move and rebind" in the NEXTTOUCH
>From what I see, on solaris, it's only supported when we bind to the
entire machine. So there's no binding, only moving there.
Linux doesn't support NEXTTOUCH yet. I think most implementations I have
seen would change the binding immediately and only move the page
(according to the binding) on next-touch.

In short, my feeling is that it's more "bind but only lazily move pages
on next touch" (compared to MIGRATE = "bind and move everything now",
and BIND = "bind but don't move already faulted pages").
