Subject: [PATCH] change CONFIG_NUMA description
Date: Wed, 5 Nov 2008 02:27:19 +0900 (JST)	[thread overview]
Message-ID: <20081105022553.7CB2.KOSAKI.MOTOHIRO@jp.fujitsu.com> (raw)


CONFIG_NUMA description talk about a bit old thing.
So, following changes are better.

o CONFIG_NUMA is no longer EXPERIMENTAL
o Opteron is not the only processor of NUMA topology on x86_64 no longer, but also Intel Core7i has it.
