The quilt patch titled
Subject: MIPS: consolidate mem_init() for NUMA machines
has been removed from the -mm tree. Its filename was
mips-consolidate-mem_init-for-numa-machines.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: MIPS: consolidate mem_init() for NUMA machines
Date: Thu, 13 Mar 2025 15:49:54 +0200
Both MIPS systems that support numa (loongsoon3 and sgi-ip27) have
identical mem_init() for NUMA case.
Move that into arch/mips/mm/init.c and drop duplicate per-machine
definitions.
