Thanks for testing!

hpa, so sorry, but it looks like we need one more patch [PATCH 2/5] x86:
find_early_table_space based on memory ranges that are being mapped:

  https://lkml.org/lkml/2012/8/24/469

on top of this, because find_early_table_space calculation does not come out
correctly for this particular E820 table that Tom has:

  http://pastebin.com/4eSPEAvB

The reason why we hit this now, and never hit it before is because before the
start was hard coded to 1UL<<32.

Thanks,

-Jacob
