From 36ce1514117b92b7372e1b041ccc686855454d33 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 21 Aug 2007 14:42:40 +0200 Subject: 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.
