[PATCH -next] riscv/mm: Fix build error while PAGE_TABLE_CHECK enabled without MMU

From: YueHaibing
Date: Fri Jun 24 2022 - 05:46:26 EST


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.

Fixes: 3fee229a8eb9 ("riscv/mm: enable ARCH_SUPPORTS_PAGE_TABLE_CHECK")
