The quilt patch titled
     Subject: mm: percpu: increase PERCPU_MODULE_RESERVE to accommodate allocation tags
has been removed from the -mm tree.  Its filename was
     mm-percpu-increase-percpu_module_reserve-to-accommodate-allocation-tags.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

Subject: mm: percpu: increase PERCPU_MODULE_RESERVE to accommodate allocation tags
Date: Thu, 21 Mar 2024 09:36:38 -0700

As each allocation tag generates a per-cpu variable, more space is
required to store them.  Increase PERCPU_MODULE_RESERVE to provide enough
area.  A better long-term solution would be to allocate this memory
dynamically.
