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. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
