[PATCH] [25/26] x86_64: x86-64 system crashes when no memory populating Node 0

[Andi Kleen <ak@suse.de>]

From: James Puthukattukaran <James.Puthukattukaran@sun.com>

I have a 4 socket AMD Operton system. The 2.6.18 kernel I have crashes
when there is no memory in node0.

AK: changed call to _nopanic
