Revert "x86-64: Reverse order of bootmem lists"

Browse Source 
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."
