The quilt patch titled
Subject: mips: rename PGD_ORDER to PGD_TABLE_ORDER
has been removed from the -mm tree. Its filename was
mips-rename-pgd_order-to-pgd_table_order.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

From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: mips: rename PGD_ORDER to PGD_TABLE_ORDER
Date: Sun, 3 Jul 2022 17:11:55 +0300
This is the order of the page table allocation, not the order of a PGD.
While at it remove unused defintion of _PGD_ORDER in asm-offsets.
