From 6e3254c4e2927c117044a02acf5f5b56e1373053 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 30 Sep 2005 12:38:27 -0700 Subject: Revert "x86-64: Reverse order of bootmem lists" As requested by Thomas Gleixner : "5d3d0f7704ed0bc7eaca0501eeae3e5da1ea6c87 breaks a couple of ARM boards, which depend on the historical bootmem allocation order. There is a cleaner solution around to remove the pgdat list completely, but this is a topic for post 2.6.14 Andi signalled ACK already."
