Yeah, same as Logan:

mm/memcontrol.c: In function ‘get_mctgt_type’:
mm/memcontrol.c:5724:29: error: implicit declaration of function
‘is_device_private_page’; did you mean
‘is_device_private_entry’? [-Werror=implicit-function-declaration]
 5724 |                         if (is_device_private_page(page))
      |                             ^~~~~~~~~~~~~~~~~~~~~~
      |                             is_device_private_entry

...needs:
