I'm sure one could add a callback in vm_fault without much issue.
However this isn't the point of the hook. One can insert the
vm object into the vm map, when a fault occurs the vm_fault code
will call the pager handler to service it.
The only good part for having a fault hook in linux is most likely
for debug purposes.
