Subject: [PATCH] [1/7] i386: Move MWAIT idle check to generic CPU initialization
Date: Wed, 16 Jan 2008 23:27:04 +0100 (CET) [thread overview]
Message-ID: <20080116222704.60FFA14EE3@wotan.suse.de> (raw)
In-Reply-To: <200801161127.268350000@suse.de>
Previously it was only run for Intel CPUs, but AMD Fam10h implements MWAIT too.
This matches 64bit behaviour.
