Its filename was mm-sparse-vmemmap-drop-unused-section_nr_vmemmap_pages-arguments.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: Muchun Song Subject: mm/sparse-vmemmap: drop unused section_nr_vmemmap_pages() arguments Date: Wed, 30 Sep 2026 22:06:26 +0800 section_nr_vmemmap_pages() no longer uses the altmap or pgmap arguments, so drop them from the helper and its callers.
