mm/page_table_check.c: In function ‘__page_table_check_pte_clear’:
mm/page_table_check.c:148:6: error: implicit declaration of function ‘pte_user_accessible_page’; did you mean ‘user_access_save’? [-Werror=implicit-function-declaration]
  if (pte_user_accessible_page(pte)) {
      ^~~~~~~~~~~~~~~~~~~~~~~~
      user_access_save

ARCH_SUPPORTS_PAGE_TABLE_CHECK should only enabled with MMU.
