After clarifying the intended semantics, the previous patch series
went the wrong way with MAP_FIXED handling, so I fixed that.
This series is not quite ready for merge. I prefer to see what x86
does exactly because it also has some fixes to make. But time is
becoming short before 4.14, so I'd like to get some more review and
testing so we can be ready.
Thanks,
Nick
