[patch 2/8] [PATCH] Fix SRAT for non dual core AMD systems

[Chris Wright <chrisw@osdl.org>]

-stable review patch.  If anyone has any  objections, please let us know.
------------------


This fixes a bug in SRAT handling on AMD systems that was introduced
with the dual core support. It would be disabled on CPUs without dual core.
Just drop the bogus check.
