mm: special mapping nopage
Convert special mapping install from nopage to fault.
Because the "vm_file" is NULL for the special mapping, the generic VM
code has messed up "vm_pgoff" thinking that it's an anonymous mapping
and the offset does't matter. For that reason, we need to undo the
vm_pgoff offset that got added into vmf->pgoff.
[ We _really_ should clean that up - either by making this whole special
mapping code just use a real file entry rather than that ugly array of
"struct page" pointers, or by just making the VM code realize that
even if vm_file is NULL it may not be a regular anonymous mmap.
