Subject: [patch 2/8] [PATCH] Fix SRAT for non dual core AMD systems
Date: Thu, 11 Aug 2005 15:54:47 -0700 [thread overview]
Message-ID: <20050811225556.869832000@localhost.localdomain> (raw)
In-Reply-To: 20050811225445.404816000@localhost.localdomain

-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.
