Instead of mapping a dummy page upon a page fault, map the page pointed to by the physical address given by IDX_TO_OFF(vmap->vm_pfn). To simplify the implementation use OBJT_DEVICE to implement our own linux_cdev_pager_fault() instead of using the existing linux_cdev_pager_populate(). Some minor code factoring while at it.
