    kernel - Change pager interface to pass page index 2/2
    
    * Adjust the DRM calls to vm_pager_get_page() to pass the
      page index.
    
    * Greatly simplify drm/linux_shmem.c and drm/ttm/ttm_bo_vm.c,
      removing the need to deal with placemarker pages for
      VM faults on OBJT_MGTDEVICE objects.
