From ffa27b6bc61c3be76a756100f777372768bcc3ab Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Fri, 28 Oct 2005 17:46:58 -0700 Subject: [PATCH] ppc64 memory model depends on NUMA Currently when we first select memory model (FLAT, DISCONTIG, SPARSE) then select whether the machine is NUMA. However NUMA systems may not be FLAT. This constraint it not honoured and we may configure a NUMA/FLAT system. Reorder the configuration such that we choose NUMA first which allows us to only list the memory models which are valid. We now default NUMA for known NUMA systems. Note that this new order also matches that used in x86.
