Its filename was mm-vma-tidy-up-map-kernel-pages-enum-values.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: "Lorenzo Stoakes (ARM)" Subject: mm/vma: tidy up map kernel pages enum values Date: Thu, 17 Sep 2026 17:22:16 +0100 MMAP_MAP_KERNEL_PAGES is a mouthful, discard the MAP_ as that's implied by MMAP. Also while we're here delete useless comments for mmap actions whose names clearly indicate what they are for. Also update the userland VMA tests to reflect this change. No functional change intended.
