The quilt patch titled
Subject: ARM: mm: rename PGD helpers
has been removed from the -mm tree. Its filename was
arm-mm-rename-pgd-helpers.patch
This patch was dropped because it was merged into the mm-stable branch

Subject: ARM: mm: rename PGD helpers
Date: Fri, 3 Jan 2025 18:44:13 +0000
Generic implementations of __pgd_alloc and __pgd_free are about to be
introduced. Rename the macros in arch/arm/mm/pgd.c to avoid clashes.
While we're at it, also pass down the mm as argument to those helpers, as
it will be needed to call the generic __pgd_{alloc,free}.
