Message-ID: <20070821124240.GJ32640@bingen.suse.de> Date: Tue, 21 Aug 2007 14:42:40 +0200 From: Andi Kleen <ak@...e.de> To: torvalds@...l.org Cc: linux-kernel@...r.kernel.org, mel@....ul.ie Subject: [PATCH for 2.6.23] i386: Mark NUMA support experimental I did some testing and found quite a lot of problems (doesn't boot at all on non NUMA and misassigns cores on Opteron systems). Mark it as experimental and warn against its use for now. It's still default y for SUMMIT/NUMAQ because it'll presumably work on these systems.
