Subject: Enable C2 for processors without CST
Date: Sat, 02 Jul 2005 18:21:37 +0200 [thread overview]
Message-ID: <da6eui$obf$1@sea.gmane.org> (raw)

Hi,
this patch reenables power saving states for CPU when CST isn't
available. It is needed to make C2 work on my AMD XP-M 2600+ with
2.6.13-rc1-mm1 kernel.
Regards,
