[PATCH] Revert [PATCH] x86-64: Reverse order of bootmem lists

[Thomas Gleixner]

Linus,

please revert the patch 

http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5d3d0f7704ed0bc7eaca0501eeae3e5da1ea6c87

as it breaks a couple of ARM boards, which depend on the historical
bootmem allocation order. AFAIK 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.
