From c94b14bd1cff085df21125a3591378c5081f143a Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Sun, 3 Jul 2022 17:11:52 +0300 Subject: [PATCH] mips: rename PMD_ORDER to PMD_TABLE_ORDER This is the order of the page table allocation, not the order of a PMD. While at it remove unused defintion of _PMD_ORDER in asm-offsets.
