Revert "x86-64: Reverse order of bootmem lists"
As requested by Thomas Gleixner <tglx@linutronix.de>: "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." Signed-off-by: Linus Torvalds <torvalds@osdl.org>
