The quilt patch titled Subject: mm: page_alloc: use div64_ul() instead of do_div() has been removed from the -mm tree. Its filename was mm-page_alloc-use-div64_ul-instead-of-do_div.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: Thorsten Blum <thorsten.blum@xxxxxxxxxx> Subject: mm: page_alloc: use div64_ul() instead of do_div() Date: Wed, 28 Feb 2024 23:49:12 +0100 Fixes Coccinelle/coccicheck warning reported by do_div.cocci. Compared to do_div(), div64_ul() does not implicitly cast the divisor and does not unnecessarily calculate the remainder.
