The quilt patch titled
Subject: mm: add pcp high_min high_max to proc zoneinfo
has been removed from the -mm tree. Its filename was
mm-add-pcp-high_min-high_max-to-proc-zoneinfo.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: add pcp high_min high_max to proc zoneinfo
Date: Thu, 10 Oct 2024 20:09:36 +0800
When we do not set percpu_pagelist_high_fraction the kernel will compute
the pcp high_min/max by itself, which makes it hard to determine the
current high_min/max values.
So output the pcp high_min/max values to /proc/zoneinfo.
