Make sure we copy pages inserted with "vm_insert_page()" on fork
Linus Torvalds authored 

The logic that decides that a fork() might be able to avoid copying a VM
area when it can be re-created by page faults didn't know about the new
vm_insert_page() case.

Also make some things a bit more anal wrt VM_PFNMAP.
