Subject: [PATCH] [10/20] i386: Move MWAIT idle check to generic CPU initialization
Date: Thu,  3 Jan 2008 01:50:05 +0100 (CET)	[thread overview]
Message-ID: <20080103005005.B13C714D40@wotan.suse.de> (raw)
In-Reply-To: <20080103149.088038000@suse.de>


Previously it was only run for Intel CPUs, but AMD Fam10h implements MWAIT too.

This matches 64bit behaviour.
