Its filename was mm-page_table_check-reinstate-address-parameter-in-page_table_check_pud_clear.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Rohan McLure Subject: mm/page_table_check: reinstate address parameter in [__]page_table_check_pud_clear() Date: Fri, 19 Dec 2025 04:09:38 +1100 This reverts commit 931c38e16499 ("mm/page_table_check: remove unused parameter in [__]page_table_check_pud_clear"). Reinstate previously unused parameters for the purpose of supporting powerpc platforms, as many do not encode user/kernel ownership of the page in the pte, but instead in the address of the access.
